• Single +5 V Power Supply Operation with PECL Logic
Interfaces
The HFCT-53D5 incorporates a 1300 nm FabryPerot (FP) Laser designed to meet the Gigabit
Ethernet LX specification. The OSA is driven
by a custom, silicon bipolar IC which converts
differential PECL logic signals (ECL referenced
to a +5 Volt supply) into an analog laser diode
drive current.
Receiver Section
The receiver of the HFCT-53D5 includes a InP
PIN photodiode mounted together with a custom,
silicon bipolar transimpedance preamplifier IC
in an OSA. This OSA is mated to a custom
silicon bipolar circuit that provides postamplification and quantization.
The post-amplifier also includes a Signal Detect
circuit which provides a PECL logic-high output
upon detection of a usable input optical signal
level. This singleended PECL output is designed
to drive a standard PECL input through a 50
Ω PECL load.

Alcohols: methyl, isopropyl, isobutyl.
Aliphatics: hexane, heptane Other: soap solution,
naphtha.
Do not use partially halogenated hydrocarbons
such as 1,1.1 trichloroethane, ketones such as
MEK, acetone, chloroform, ethyl acetate,
methylene dichloride, phenol, methylene chloride,
or N-methylpyrolldone. Also, Avago Technologies
does not recommend the use of cleaners that
use halogenated hydrocarbons because of their
potential environmental harm.
Regulatory Compliance
(See the Regulatory Compliance Table for
transceiver performance)
The overall equipment design will determine
the certification level. The transceiver
performance is offered as a figure of merit to
assist the designer in considering their use in
equipment designs.
Electrostatic Discharge (ESD)
There are two design cases in which immunity
to ESD damage is important. The first case is
2
during handling of the transceiver prior to
mounting it on the circuit board. It is important
to use normal ESD handling precautions for
ESD sensitive devices. These precautions include
using grounded wrist straps, work benches,
and floor mats in ESD controlled areas. The
transceiver performance has been shown to
provide adequate performance in typical industry
production environments.
The second case to consider is static discharges
to the exterior of the equipment chassis
containing the transceiver parts. To the extent
that the duplex SC connector receptacle is
exposed to the outside of the equipment chassis
it may be subject to whatever system-level
ESD test criteria that the equipment is intended
to meet. The transceiver performance is more
robust than typical industry equipment
requirements of today.
Electromagnetic Interference (EMI)
Most equipment designs utilizing these highspeed transceivers from Avago Technologies will
be required to meet the requirements of FCC
in the United States, CENELEC EN55022 (CISPR
22) in Europe and VCCI in Japan. Refer to
EMI section (page 5) for more details.
Immunity
Equipment utilizing these transceivers will be
subject to radio-frequency electromagnetic fields
in some environments. These transceivers have
good immunity to such fields due to their
shielded design.
Eye Safety
These laser-based transceivers are classified as
AEL Class I (U.S. 21 CFR(J) and AEL Class 1
per EN 60825-1 (+A11). They are eye safe
when used within the data sheet limits per
CDRH. They are also eye safe under normal
operating conditions and under all reasonably
forseeable single fault conditions per EN608251. Avago Technologies has tested the transceiver
design for compliance with the requirements
listed below under normal operating conditions
and under single fault conditions where
applicable. TUV Rheinland has granted
certification to these transceivers for laser eye
safety and use in EN 60950 and EN 60825-2
applications. Their performance enables the
transceivers to be used without concern for
eye safety up to 7 volts transmitter VCC.
CAUTION:
There are no user serviceable parts nor any
maintenance required for the HFCT-53D5. All
adjustments are made at the factory before
shipment to our customers. Tampering with or
modifying the performance of the HFCT-53D5
will result in voided product warranty. It may
also result in improper operation of the HFCT53D5 circuitry, and possible overstress of the
laser source. Device degradation or product
failure may result.
Connection of the HFCT-53D5 to a nonapproved
optical source, operating above the recommended
absolute maximum conditions or operating the
HFCT-53D5 in a manner inconsistent with its
design and function may result in hazardous
radiation exposure and may be considered an
act of modifying or manufacturing a laser
product. The person(s) performing such an act
is required by law to recertify and reidentify
the laser product under the provisions of U.S.
21 CFR (Subchapter J).

APPLICATION SUPPORT
Optical Power Budget and Link Penalties
The worst-case Optical Power Budget (OPB) in
dB for a fiberoptic link is determined by the
difference between the minimum transmitter
output optical power (dBm avg) and the lowest
receiver sensitivity (dBm avg). This OPB provides
the necessary optical signal range to establish
a working fiber-optic link. The OPB is allocated
for the fiber-optic cable length and the
corresponding link penalties. For proper link
performance, all penalties that affect the link
performance must be accounted for within the
link optical power budget. The Gigabit Ethernet
IEEE 802.3z standard identifies, and has
modeled, the contributions of these OPB penalties
to establish the link length requirements for
62.5/125 mm and 50/125 mm multimode fiber
usage. In addition, single-mode fiber with
standard 1300 nm Fabry-Perot lasers have been
modeled and specified. Refer to the IEEE 802.3z
standard and its supplemental documents that
develop the model, empirical results and final
specifications.
10 km Link Support
As well as complying with the LX 5 km standard,
the HFCT-53D5 specification provides additional
margin allowing for a 10 km Gigabit Ethernet
link on single mode fiber. This is accomplished
by limiting the spectral width and center
wavelength range of the transmitter while
increasing the output optical power and improving
sensitivity. All other LX cable plant
recommendations should be followed.
Data Line Interconnections
Avago Technologies’ HFCT-53D5 fiber-optic
transceiver is designed to directly couple to +5
V PECL signals. The transmitter inputs are
internally dc-coupled to the laser driver circuit
from the transmitter input pins (pins 7, 8).
There is no internal, capacitively-coupled 50
Ohm termination resistance within the
transmitter input section. The transmitter driver
circuit for the laser light source is a dccoupled circuit. This circuit regulates the output
optical power. The regulated light output will
maintain a constant output optical power
4
provided the data pattern is reasonably balanced
in duty factor. If the data duty factor has long,
continuous state times (low or high data duty
factor), then the output optical power will
gradually change its average output optical power
level to its pre-set value.
As for the receiver section, it is internally accoupled between the pre-amplifier and the
postamplifier stages. The actual Data and Databar outputs of the postamplifier are dc-coupled
to their respective output pins (pins 2, 3).
Signal Detect is a single-ended, +5 V PECL
output signal that is dc-coupled to pin 4 of
the module. Signal Detect should not be accoupled externally to the follow-on circuits
because of its infrequent state changes.
Caution should be taken to account for the
proper interconnection between the supporting
Physical Layer integrated circuits and this HFCT53D5 transceiver. Figure 3 illustrates a
recommended interface circuit for interconnecting
to a +5 Vdc PECL fiber-optic transceiver.
Some fiber-optic transceiver suppliers’ modules
include internal capacitors, with or without 50
Ohm termination, to couple their Data and
Data-bar lines to the I/O pins of their module.
When designing to use these type of transceivers
along with Avago Technologies transceivers, it
is important that the interface circuit can
accommodate either internal or external
capacitive coupling with 50 Ohm termination
components for proper operation of both
transceiver designs. The internal dc-coupled
design of the HFCT-53D5 I/O connections was
done to provide the designer with the most
flexibility for interfacing to various types of
circuits.
Eye Safety Circuit
For an optical transmitter device to be eyesafe in the event of a single fault failure, the
transmitter must either maintain normal, eyesafe operation or be disabled.
The HFCT-53D5 utilizes an integral fiber stub
along with a current limiting circuit to guarantee
eye-safety. It is intrinsically eye safe and does
not require shut down circuitry.
Signal Detect
The Signal Detect circuit provides a deasserted
output signal that implies the link is open or
the transmitter is OFF as defined by the Gigabit
Ethernet specification IEEE 802.3z, Table 38.1.
The Signal Detect threshold is set to transition
from a high to low state between the minimum
receiver input optional power and –30 dBm
avg. input optical power indicating a definite
optical fault (e.g. unplugged connector for the
receiver or transmitter, broken fiber, or failed
far-end transmitter or data source). A Signal
Detect indicating a working link is functional
when receiving encoded 8B/10B characters. The
Signal Detect does not detect receiver data
error or error-rate. Data errors are determined
by Signal processing following the transceiver.
Electromagnetic Interference (EMI)
One of a circuit board designer’s foremost
concerns is the control of electromagnetic
emissions from electronic equipment. Success
in controlling generated Electromagnetic
Interference (EMI) enables the designer to pass
a governmental agency’s EMI regulatory standard;
and more importantly, it reduces the possibility
of interference to neighboring equipment. There
are two options for the HFCT-53D5 with regard
to EMI shielding which provide the designer
with a means to achieve good EMI performance.
The EMI performance of an enclosure using
these transceivers is dependent on the chassis
design. Avago Technologies encourages using
standard RF suppression practices and avoiding
poorly EMI-sealed enclosures.
The first configuration, option EM, is for EMI
shielding applications where the position of the
transceiver module will extend outside the
equipment enclosure. The metallized plastic
package and integral external metal shield of
the transceiver helps locally to terminate EM
fields to the chassis to prevent their emissions
outside the enclosure. This metal shield contacts
the panel or enclosure on the inside of the
aperture on all but the bottom side of the
shield and provides a good RF connection to
the panel. This option can accommodate various
panel or enclosure thickness, i.e., .04 in. min.
to 0.10 in. max. The reference plane for this
panel thickness variation is from the front
surface of the panel or enclosure. The
recommended length for protruding the HFCT-
5
53D5EM transceiver beyond the front surface
of the panel or enclosure is 0.25 in. With this
option, there is flexibility of positioning the
module to fit the specific need of the enclosure
design. (See Figure 5 for the mechanical drawing
dimensions of this shield.)
The second configuration, option FM, is for
applications that are designed to have a flush
mounting of the module with respect to the
front of the panel or enclosure. The flushmount design accommodates a large variety of
panel thickness, i.e., 0.04 in. min. to 0.10 in.
max. Note the reference plane for the flushmount design is the interior side of the panel
or enclosure. The recommended distance from
the centerline of the transceiver front solder
posts to the inside wall of the panel is 0.55 in.
This option contacts the inside panel or
enclosure wall on all four sides of this metal
shield. See Figure 7 for the mechanical drawing
dimensions of this shield.
The two metallized designs are comparable in
their shielding effectiveness. Both design options
connect only to the equipment chassis and not
to the signal or logic ground of the circuit
board within the equipment closure. The front
panel aperture dimensions are recommended
in Figures 6 and 8. When layout of the printed
circuit board is done to incorporate these metalshielded transceivers, keep the area on the
printed circuit board directly under the metal
shield free of any components and circuit board
traces. For additional EMI performance
advantage, use duplex SC fiber-optic connectors
that have low metal content inside them. This
lowers the ability of the metal fiber-optic
connectors to couple EMI out through the
aperture of the panel or enclosure.

Notes:
1. The maximum Optical Output Power complies with the IEEE 802.3z specification, and is class 1 laser eye safe.
2. Optical Extinction Ratio is defined as the ratio of the average output optical power of the transmitter in the high (“1”) state to the low (“0”) state. The
transmitter is driven with a Gigabit Ethernet 1250 MBd 8B/10B encoded serial data pattern. This Optical Extinction Ratio is expressed in decibels
(dB) by the relationship 10log(Phigh avg/Plow avg).
3. These are unfiltered 20-80% values.
4. Laser transmitter pulse response characteristics are specified by an eye diagram (Figure 2). The characteristics include rise time, fall time, pulse
overshoot, pulse undershoot, and ringing, all of which are controlled to prevent excessive degradation of the receiver sensitivity. These parameters
are specified by the referenced Gigabit Ethernet eye diagram using the required filter. The output optical waveform complies with the requirements
of the eye mask discussed in section 38.6.5 and Fig. 38-2 of IEEE 802.3z.
5. TP refers to the compliance point specified in 802.3z, section 38.2.1.
6. The receive sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.
7. The stressed receiver sensitivity is measured using the conformance test signal defined in 802.3z, section 38.6.11. The conformance test signal is
conditioned by applying deterministic jitter and intersymbol interference.
8. The stressed receiver jitter is measured using the conformance test signal defined in 802.3z, section 38.6.11 and set to an average optical power 0.5
dB greater than the specified stressed receive sensitivity.
9. The 3 dB electrical bandwidth of the receiver is measured using the technique outlined in 802.3z, section 38.6.12.
10. Return loss is defined as the minimum attenuation (dB) of received optical power for energy reflected back into the optical fiber.
