Introduction to H-PCF Optical Fiber Cables
On the outside, Optical Fiber Cords and Cables look like electrical cords and
cables. However, instead of metal wires carrying electrical signals, Optical
Fiber Cords and Cables use quartz-glass fibers with a hard-clad coating
(hard acrylic fluoride plastic) to carry light signals. Optical signals travel
through the glass fiber for distances up to 1 km. Though the plastic coating
protects the glass fiber, Optical Fiber Cords and Cables require much greater
care during handling and installation than conventional electrical cords and
cables. It is very important to protect the cord and cable from impact, and
care should be taken to avoid excessive bending or twisting of the cord and
cable. The Optical Fiber Cords are intended for indoor use while the Optical
Fiber Cables are intended for outdoor use.
The following diagram shows the construction of the SI-type (step index type)
multimode optical fiber used in H-PCF Optical Fiber Cables. The optical fiber
shown below consists of a quartz-glass fiber with a hard plastic coating.

The H-PCF optical fiber’s mechanical strength and resistance to temperature
changes is increased by its soft fluoroplastic (ETFE) jacket. The following
diagram compares the construction of the H-PCF hard-clad fiber (HC-20/07)
to the older PCF silicon-clad fiber (PC-20/07).

Features of H-PCF Optical Fiber
This section describes the basic features of H-PCF Optical Fiber Cables.
Signal Loss vs. Wavelength H-PCF optical fibers have a stable signal loss at a wavelength of about
0.8 mm. The signal loss for H-PCF is equal to or better than the low loss levels of the older PCF optical fibers (about 4 to 6 dB).
The following graph shows signal loss vs. wavelength for a 1 km CCVHC-20/07 H-PCF Optical Fiber Cord at a temperature of 25°C (77°F).

Wavelength (mm)
Signal Loss vs. Distance
The maximum signal loss (α) for a given length (L) of two-fiber DCVHC-20/07 optical fiber can be calculated from the following equations. Equation 1 is for a wavelength of 0.810 mm at a temperature of 25°C (77°F), and
equation 2 is for a wavelength of 0.655 mm at a temperature of 25°C (77°F).
1) α(L) ≤ (7–4×log(L))×L dB (for λ = 0.810 mm and T = 25°C)
2) α(L) ≤ (15–4×log(L))×L dB (for λ = 0.655 mm and T = 25°C)

Connectors
Since the H-PCF optical fibers are hard-clad, it is possible to use crimp connectors as well as the older style that requires gluing and polishing. This is the most
important characteristic of H-PCF optical fibers, and greatly simplifies the attachment of connectors.

Connector Assembly
The specialized connector assembly tools needed to attach connectors to the
H-PCF Optical Fiber Cord or Cable on site must be purchased separately. All of
the required tools are included in the Optical Connector Assembly Tool Kit in a
compact carrying case. Refer to Appendix A Standard Models for ordering information.
In the past, attaching connectors to the optical fiber required time-consuming
gluing and polishing, but crimp connectors can be attached quickly and easily
using a ferrule crimper and optical fiber cutter. Refer to 3-4 Optical Power Testing for details on testing light transmission through the connector/fiber junction
with an Optical Power Tester.

This manual does not provide information regarding oil and chemical resistance
of cords and cables or specifications for special applications in which the cord or
cable is subjected to bending motions. Consult your OMRON dealer for details
on these specifications.
Caution
4-2
An Optical Fiber Cable or Cord’s transmission characteristics will deteriorate if it
is stretched beyond 0.2%. Be sure to pull the Optical Fiber Cable or Cord by the
tension member and observe the tensile load limits listed in the specifications.
Do not allow the cable or cord to be stretched by a falling load, or bent or twisted
to an extreme angle.
Installation Conditions
The following table provides information for installing Optical Fiber Cord or
Cable in a variety of conditions.
Installation
Optical Fiber Cord
Optical Fiber Cable
Hanging Rack
Provide adequate protection.
Protect the cable when there are external
forces that might damage the cable.
Trough
Use a cover, etc., to provide adequate protection.
Protect the cable when there are external
forces that might damage the cable.
Electrical Conduit Use steel electrical conduit, PVC pipe, or plastic duct.
Use steel electrical conduit, PVC pipe, or
plastic duct.
Outdoor Conduit
A connector-less cord can be laid in an outdoor conduit if locations subject to flooding or high temperature
are avoided. (see note 1)
Be sure to avoid locations subject to flooding or high temperature. (see note 1)
Elevated Wiring
Not recommended.
Be sure to prevent excessive tensile vibrations.
Buried Wiring
Not recommended.
Not recommended. (see note 2)
Note
4-3
1. The outer sheath of cords and cables is PVC. Consult your OMRON dealer if
the installation site has oils or chemicals that can damage PVC. Also consult
your dealer if the cable will be subject to movement.
2. It is possible to bury a cable if special construction is used. Consult your OMRON dealer for details.
Basic Installation Methods
4-3-1 Preparing a Cord for Pulling
Optical Fiber Cords must not be pulled by their optical fibers, but by the cord’s
reinforcement material. This section describes three methods for preparing a
24
Basic Installation Methods
Section 4-3
loop at the end of an Optical Fiber Cord. These methods will not make the end of
the cord watertight. If the cord is being pulled through water, be sure to treat the
end of the cord so it is watertight.
Example 1
The following diagram and list describe the basic procedure for preparing an Optical Fiber Cord for pulling.
Approx. 40 mm
Approx. 50 mm
(1)
(4)
1, 2, 3...
(3)
(5)
(2)
1. First remove about 300 mm of the outer PVC sheath from the end of the Optical Fiber Cord (1).
2. Wrap about 1 mm of adhesive PVC tape (3) about 40 mm from the end of the
PVC sheath.
3. Create a loop by folding back the internal reinforcement material (2) about
50 mm from the end of the PVC sheath and secure it to the cord by wrapping
PVC tape around it (4).
4. Wrap another layer of tape around the reinforcement material close to the
end of the PVC sheath (5).
5. Finally, wrap the end of the cord from the exposed PVC sheath to close the
the loop made from the reinforcement material. This last layer of PVC tape
will protect the end of the cord but won’t make it watertight.
6. When laying the cord, connect a lead wire to the loop of reinforcement material and pull the cord.
Example 2
In order to increase the tensile force that can be applied when laying the cord, a
loop knot can be tied in the reinforcement material. The end of the cord should
then be covered from the PVC sheath past the loop knot. This treatment will not
make the end of the cord watertight.

tain climbers when the rope is tied around the body and can be mastered quickly
by beginners.
Example 3
If the cord is being pulled through a relatively large conduit, a cord can be folded
back onto itself and taped to make a loop. If this method is used, the end of the
cord which was folded will be damaged and cannot be used to transmit light. Cut
off the end of the cord after it has been installed.
4-3-2 Preparing a Cable for Pulling
Optical Fiber Cables must not be pulled by their optical fibers or power wires, but
by the cable’s tension member. The methods described here will not make the
end of the cable watertight. If the cord is being pulled through water, be sure to
treat the end of the cable so it is watertight.
Cable Without a Connector
Follow the procedure below to prepare an Optical Fiber Cable without a connector attached.

Tension member (3)
300 to 500 mm
Optical Fiber Cord or Power Wire (2)
Steel wire
(pulling wire)
PVC adhesive tape (4)
1, 2, 3...
1. First remove 300 to 500 mm of the outer PVC sheath from the end of the

4-3-3 Cord or Cable Installation
This section describes three methods for pulling cable through conduit. When
pulling the cord or cable from the reel, raise it off of the ground with a reel jack so
that it can turn easily. Pull the cable off of the reel while spinning the reel so that
only moderate force is place on the cable itself.
Cable reel
Reel jack
When removing cable from the reel, apply less than 2/3 of the maximum tensile
load for the cable and unreel the cable at less than 10 m/min.
One-way Pulling
With this method, the cord or cable is pulled or laid in one direction. Pull the cable
from the higher to the lower end of the route if one end is higher than the other
and pull from the end closest to the turn if there is a turn or bend in the route.
Station people along the route to monitor the installation or pull the cable to avoid
excessive force (pulling tension, compression, bending, or twisting) on the
cable. Insert a tension meter to monitor pulling tension if the tension is suspected
to be too great.
Midpoint puller
(Station a puller along the pulling
route if the tension is too high.)
Endpoint puller
Pull steadily by hand or winch.
27
Basic Installation Methods
Multiple-stage Pulling
Section 4-3
With this method the cable is installed in one direction, but the cable is pulled
through the route in stages. The remainder of the cable is temporarily piled in
figure-eight layers at the end of each successive stage. A single stage might be
selected because it is a practical pulling distance or because it ends at a turn in
the route.
In the following example, a cable is laid in two stages which are separated by a
90° turn.
(1)
(1)
Stage #1
Intermediate point
Stage #2
(2)
1, 2, 3...
Two-way Pulling
28
1. Pull or lay all of the required cable through stage #1 and pile the remaining
cable in figure-eight layers at the turn in the installation route.
2. Pull or lay the second stage of the installation route from the turn, taking care
not to tangle or twist the cable.
3. Repeat steps 1 and 2 for installation routes with 3 or more stages.
If it is impossible to install the cable in one direction because of restricted access
or sharp turns along the route, pull the cable in two directions from an intermediate point on the route.
Install the cable in one direction, remove the remaining cable from the reel and
pile it in figure-eight layers, and install that part of the cable in the opposite direction.
Installation Precautions
Section 4-4
Be sure to follow the precautions described above under the heading “one-way
pulling” and eliminate any bends or twists in the cable after installation.

3. Install the remaining cable in the second part of the installation route, taking
care not to tangle or twist the cable (3).
Installation Precautions
4-4-1 Rack or Trough Installation
Install the cord or cable on the rack (or in the trough) being careful not to apply
too much tension, bending, or twisting, and allowing a little slack (about 10
mm/m).
2m
Saddles
Saddle
(The cable should not be too loose, nor too tight.)
Do not install the cord or cable on top of or between power supply wires. The
power wires might cut into the cord or cable or pinch it, increasing the pulling
tension. Allow at least 10 mm between the Optical Fiber Cord or Cable and
power supply wires or install the Optical Fiber Cord or Cable off to the side,
as shown below.

Installation Precautions
Section 4-4
Note Be sure to protect the connector on Optical Fiber Cords or Cables that have connectors attached. In particular, use a protective cap to prevent the tip of the connector from being contaminated by dirt.
4-4-2 Installation in Electrical Conduit
Use a steel conduit, high or low-relief PVC pipe, or flexible plastic pipe. Use a
conduit with a diameter taken from the following table.

The inside of the conduit should be smooth, without any projections or joints
that might impede the cord or cable. Install just one Optical Fiber Cord or
Cable in a conduit.
The length of the conduit should be no more than 25 meters when the conduit is straight and level. When the conduit has bends along its path, the
overall length should be approximately 20 meters or less. When the route is
vertical, pull boxes (about 200 × 300 × 700 mm) should be installed at intervals of approximately eight meters.
In the following diagram P.B. indicates a pull box.

Use a pre-bent piece of pipe or bend the conduit with a pipe bending tool.
The radius of the bend should be at least six times larger than the internal

Section 4-4
diameter of the conduit. Attach a bushing and saddles at the end of the conduit so that the Optical Fiber Cable does not bend at too sharp an angle.
Normal conduit bend
Turns in the installation route should be avoided if possible, but if a turn must
be made, pull boxes are preferred to bends in the conduit. The pull boxes
should be large enough to allow the Optical Fiber Cord or Cable to bend with
a large enough radius, and the connecting conduit should be straight.
The Optical Fiber Cord or Cable can be installed by the “multiple-stage pulling” or “two-way pulling” methods described in 4-3-3 Cord or Cable Installation. Three stages would be required for the route shown in the following diagram.
Pull box
(1)
(2)
(3)
Pull box
Use the pull boxes as intermediate points when installing the cable. Pull the
cable through the first pull box and set aside the remainder in figure-eight
layers as described in 4-3-3 Cord or Cable Installation. Repeat this process
for each pull box, being careful not to pull, bend, or twist the cable excessively.
The pull box must be large enough to allow room for the minimum bend radius shown in the following table plus some room for expansion.
Item
Bend Radius at Installation
Bend Radius after Installation
Optical Fiber Cord
Greater than 60 mm
Greater than 30 mm
Optical Fiber Cable
Greater than 200 mm
Greater than 100 mm
Insert bushings at the entrance and exit of the pull box and guides to prevent
sharp bends in the cable. The cable should be held in place and not move
freely.
If the area where the turn must be made is inaccessible (when the electrical
conduit bends), two bends can be made very carefully in the conduit. The
installation will be limited by the radius of the bends (R), angle of the

4-4-3 Installation in Ducts
The instructions for installation in electrical conduits also apply to installation
in ducts. Flooding might occur in outdoor underground installation sites, so
be sure to waterproof the end of the Optical Fiber Cord or Cable with a waterproofing compound or adhesive tape before pulling it through the duct.
4-4-4 Elevated Installation
Optical Fiber Cables can be hung from a support cable like ordinary low-tension power lines. It is not recommended to hang Optical Fiber Cords, especially outdoors.
Support the Optical Fiber Cable from a sufficiently thick support cable (greater than the earlier 22 mm2 metal cable) using suitable hooks spaced at intervals of 50 mm max.
Support cable
50 cm max.
32
Securing the Cord or Cable
Section 4-5
Gently unreel the Optical Fiber Cable at less than 10 m/min by spinning the
reel, so that no pulling tension is applied to the Optical Fiber Cable itself. Be
sure not to apply any force to the cable (tension, bending, compression,
twisting, or impact) during installation that exceeds its maximum specifications.
The minimum bend radius for an Optical Fiber Cable during installation is
200 mm (20 times the cable diameter). Use a a tool such as a pulley at
bends of the cable to ensure that the bends exceed the minimum radius.
When installing straight sections, use pulleys as guides to ensure that the
tension on the cable does not exceed the maximum value. Set the pulleys no
more than 25 meters apart and allow the cable to sag at least 0.5 m.
Use a tension meter to monitor the tension in the cable if it is suspected to be
too high, and pull the cable along the installation route by hand or other
means if the tension is found to be too high.
Note It is good practice to leave about 2 or 3 meters of spare cable before each
node connection. This margin of cable allows room for attaching the connector and some repositioning of the node.
4-5
Securing the Cord or Cable
After laying the Optical Fiber Cord or Cable along the installation route, remove
the tape or tube used to protect the end of the cable. If a ferrule is going to be
attached to the end of the cable, clean the end of the ferrule surface with water
and wipe it with a soft, clean, and lint-free cloth or paper towel.
Optical Fiber Cord
When installed in a rack or trough, secure the cord gently with mounting brackets
or saddles to prevent movement. Be sure not to attach the brackets or saddles
too tightly, because excessive compression will damage the cord.
At the last mounting bracket, bushing, or saddle, protect the cord with a rubber
ring, strip of rubber, or a few layers of PVC tape and secure it. Leave enough
slack in the cord to attach and remove the connector or move the node, if necessary.

Optical Fiber Cable
When installed in a rack or trough, secure the cable with mounting brackets or
saddles to prevent movement. Be sure not to attach the brackets or saddles too
tightly, because excessive compression will damage the cable.
Use a bushing with a rubber ring, saddle, etc., to secure the cable to the wall of
the housing or panel where the cable ends. If the bushing or saddle is too large
for the cable, wrap a strip of rubber or a few layers of PVC tape so it fits snugly.
Leave 2 to 3 m of slack in the cable if connectors are being attached on site.
Take up any slack from the tension member and fasten it securely. The tension
member’s metal fastener must be properly grounded. Always secure the tension
member.

1. Protect the end of the cable with conduit if the exposed cable is in a location
where it might be stepped on or damaged accidentally.
2. If conduit is used, insert a bushing at the end of the conduit and use saddles
or guides to prevent the cable from being bent at too severe an angle.
Increasing Cable Length
In general, an Optical Fiber Cord or Cable that is not long enough should be replaced with a cord or cable of sufficient length.
When a cord or cable is installed in a trough or rack, the connection point is indoors and accessible, and an increase in signal loss of 1.5 dB is acceptable, an
extension cable can be connected with an inline adapter. Transmissions with
two cables connected by an inline adapter are less reliable than transmissions
through a single cable.
Use of an inline adapter in conduit, duct, or elevated installation should be
avoided because of reliability concerns.
