Product Overview
The Model 1188 Optical Splitter/Coupler provides the ability to create a variety of
point-to-multipoint fiber optic networks. Used with Force’s CATVLinx® transport
products, the 1188 allows a single transmitter to power two, four, six, eight, ten,
12, or 16 optical receivers with very low insertion loss and excellent flatness. The
Model 1188 accepts both 1310 nm and 1550 nm optical inputs and splits the signal
into the required number of optical outputs for distribution to separate receive
locations. For each configuration, Force offers two performance grades for the
splitter/coupler, allowing private network providers to configure their exact
requirements while providing the most cost-effective solution.

Applications
Figure 1.1 illustrates the Model 1188 in a multichannel CATV network using a
redundant fiber path configuration via the Model 5615 Optical A/B Switch. In this
application, eight CATV transmitters feed into an eight channel CWDM or DWDM
which feeds the Model 1188 Optical Splitter/Coupler. The two outputs of splitter
connect to the A and B inputs of the Model 5615 switch. Normally each fiber will
take a different route to improve reliability. At the receive end, The A/B switch
feeds a CWDM or DWDM which outputs the original CATV signals.
Figure 1.1 CWDM CATV Network in a Redundant Path Configuration
Figure 1.2 illustrates a basic point-to-multipoint CATV network. In this configuration, the splitter at the main transmit section feeds multiple receive sections.

Installation and Operation
Initial Power-up
1) Install the Model 1188 as described in Section 2, page 5 of this document.
2) Clean the optical connectors. See Section 3.2, page 9 for cleaning instructions.
3) Connect the “Common” connector to the optical transmitter optical output.
Be sure that the fiber has continuity and less the allowable optical loss for the
transmitter.
4) Connect optical connections 3-25 from the Model 1188 to the optical receivers.
5) Apply power to the optical transmitter and receivers as detailed in the user
manuals for the companion equipment. Assuming that the transmitter and
receivers are operating properly, the units are now fully operational. No additional user adjustment or attention is required. See Section 3.2, page 9 for
instructions on maintaining and cleaning the link.
2.9
Troubleshooting
The Model 1188 Optical Splitter/Coupler is a passive device and rarely represents
a point of failure for a point-to-multipoint system. Be sure to maintain clean optical
connections at all times. More common problems involve the optical transport terminals, including using an optical transmitter as a receiver and vice versa, lack of
continuity in the optical fiber, lack of power (or reversed power) at the transmitter
or receiver ends, or improper transmitter or receiver input levels. If problems persist contact the factory.

Section 3 Maintenance
and Safety Precautions
3.1
Unit Maintenance
No user maintenance is required. The Model 1188 contains no user serviceable
parts and requires no routine service. Contact the factory if the unit requires warranty repair work.
3.2
Cleaning
If the units need to be cleaned, avoid the use of all solvents and use low-pressure
clean air to remove loose dirt. Use low-pressure clean air to clear the connectors
of any debris. Dirty or scratched connector end faces will greatly reduce the unit’s
performance. Foam-tipped swabs such as the 2.5mm Mini Foam Swab offered by
Fiber Instrument Sales (P/N F1-0005) may be saturated with denatured alcohol
and inserted into the optical port for cleaning. DO NOT INSERT A DRY SWAB
INTO THE OPTICAL PORT AS THIS MAY DAMAGE THE FIBER END FACE. Many
fiber optic installations experience degraded performance due to dirty optical connector end faces. The following procedure should be used to properly clean the
optical connector end faces.
3.2.1
Optical Connector Cleaning Equipment
• Kimwipes® or any lens-grade, lint-free tissue. The type sold for eyeglasses work
quite well.
• Denatured Alcohol.
NOTE
Use only industrial grade 99% pure isopropyl alcohol. Commercially available isopropyl
alcohol is for medicinal use and is diluted with water and a light mineral oil. Industrial
grade isopropyl alcohol should be used exclusively.
• 30X Microscope.
• Canned Dry Air.
3.2.2
Directions for Optical Connector Cleaning
1) Fold the tissue twice so it is four layers thick.
2) Saturate the tissue with alcohol.
3) First clean the sides of the connector ferrule. Place the connector ferrule in
the tissue, and apply pressure to the sides of the ferrule. Rotate the ferrule several times to remove all contamination from the ferrule sides.
Revision 2.0

Maintenance and Safety
Model 1188 Optical Splitter/Coupler
4) Now move to a clean part of the tissue. Be sure it is still saturated with alcohol,
and it is still four layers thick. Put the tissue against the end of the connector
ferrule. Put your fingernail against the tissue so that it is directly over the ferrule. Now scrape the end of the connector until it squeaks. It will sound like a
crystal glass that has been rubbed when it is wet.
5) Use the microscope to verify the quality of the cleaning. If it isn’t completely
clean repeat the steps with a clean tissue.
6) Mate the connector immediately! Don’t let the connector lie around and collect dust before mating.
7) Air can be used to remove lint or loose dust from the port of a transmitter or
receiver to be mated with the connector. Never insert any liquid into the
ports.
3.2.3
Connector Handling
1) NEVER TOUCH THE FIBER END FACE OF THE CONNECTOR.
2) Connectors not in use should be covered over the ferrule by a plastic dust
cap. It is important to note that inside of the ferrule dust caps contains a sticky
gelatinous residue that is the by-product of the making of the dust cap. This
residue will remain on the ferrule end after the cap is removed. Therefore it is
critical that the ferrule end be cleaned thoroughly BEFORE it is mated to the
intended unit.
3.3
Safety Precautions
The optical emission from the units are laser-based Class IIIb, and may present eye
hazards if improperly used. NEVER USE ANY KIND OF OPTICAL INSTRUMENT TO VIEW THE OPTICAL OUTPUT OF THE UNIT. As always, be careful when working with optical fibers. Fibers can cause painful injury if they
penetrate the skin.
3.3.1
Laser Safety Procedures
1) ALWAYS read the product data sheet and the laser safety label before powering the product. Note the operating wavelength, optical output power, and
safety classification.
2) If safety goggles or other eye protection are used, be certain that the protection is effective at the wavelength(s) emitted by the device under test
BEFORE applying power.
3) ALWAYS connect a fiber to the output of the device BEFORE power is
applied. Power should never be applied without an attached fiber output. If
the device has a connector output, a connector should be attached that is
connected to a fiber. This ensures that all light is confined within the fiber
waveguide, virtually eliminating all potential hazard.
4) NEVER look in the end of a fiber to see if light is coming out. NEVER! Most
fiber optic laser wavelengths (1310 nm and 1550 nm) are totally invisible to
the unaided eye and will cause permanent damage. Shorter wavelength
lasers (e.g. 780 nm) are visible and are very damaging. Always use instruments, such as an optical power meter, to verify light output.
5) NEVER NEVER NEVER look into the end of a fiber on a powered device
with ANY sort of magnifying device. This includes microscopes, eye loupes,
and magnifying glasses. This WILL cause a permanent, irreversible burn on
your retina. Always double check that power is disconnected before using
such devices. If possible, completely disconnect the unit from any power
source.

Shipping and Handling Precautions
The units are, in general, very rugged and can withstand the stresses of most shipping and handling circumstances. However, the following precautions should be
taken:
1) When the units are shipped they should be wrapped in a protective material,
such as bubble wrap, to protect against excessive jarring and to prevent damage to the external finish of the units. Always use packing material to separate
multiple units that are packaged together.
2) Care should be taken not to drop or strike the units in any way, especially
around the optical connectors.
3) The units should never be submersed in any liquid.
3.5
Storing the Unit
If a unit is to be out of use for an extended period of time, the following steps
should be taken to ensure the preservation of the unit:
1) The storage temperature range is -40°C to +85°C.
2) A low humidity environment is preferable for long term storage.
3) All connectors should be covered with active device receptacle caps.
3.6
Repair Service
For equipment repair or technical assistance, contact Customer Service (800) 7325252 (USA) or (540) 382-0462. A Returned Material Authorization (RMA) number
must be issued by Customer Service before the return of a failed unit. Units should
be returned in their original shipping carton, if available. Always include a complete description of the failure or observed anomalies. All units are marked with
model number and serial number. This identification sticker is placed on the rear
panel or on the product label. The serial number is a date code used as a reference for warranty service.
