Applications
Functional Description
Receiver Section
Design
The receiver section for the
HFCT-5963xxx contains an
InGaAs/InP photo detector and a
preamplifier mounted in an
optical subassembly. This optical
subassembly is coupled to a
postamp/decision circuit on a
circuit board. The design of the
optical assembly is such that it
provides better than 14 dB
Optical Return Loss (ORL).
Figure 1 also shows a filter
function which limits the
bandwidth of the preamp output
signal. The filter is designed to
bandlimit the preamp output
noise and thus improve the
receiver sensitivity.
These components will reduce
the sensitivity of the receiver as
the signal bit rate is increased
above 155 Mb/s.
The postamplifier is ac coupled to
the preamplifier as illustrated in
Figure 1. The coupling capacitors
are large enough to pass the
SONET/SDH test pattern at
155 Mb/s without significant
distortion or performance
penalty. If a lower signal rate, or
a code which has significantly
more low frequency content is
used, sensitivity, jitter and pulse
distortion could be degraded.

Package
The overall package concept for
these devices consists of the
following basic elements; two
optical subassemblies, two
electrical subassemblies and the
housing as illustrated in the
block diagram in Figure 3.
The package outline drawing and
pin out are shown in Figures 4
and 5. The details of this package
outline and pin out are compliant
with the multisource definition
of the 2 x 5 DIP. The low profile
of the Agilent transceiver design
complies with the maximum
height allowed for the LC
connector over the entire length
of the package.
The electrical subassemblies
consist of high volume
multilayer printed circuit boards
on which the IC and various
surface-mounted passive circuit
elements are attached.
encased with a metal EMI
protective shield. The case is
connected to signal ground and
we recommend soldering the four
ground tabs to host card signal
ground.
The receiver electrical
subassembly includes an internal
shield for the electrical and
optical subassembly to ensure
high immunity to external EMI
fields.
The PCBs for the two electrical
subassemblies both carry the
signal pins that exit from the
bottom of the transceiver. The
solder posts are fastened into the
molding of the device and are
designed to provide the
mechanical strength required to
withstand the loads imposed on
the transceiver by mating with
the LC connectored fiber cables.
Although they are not connected
electrically to the transceiver, it
is recommended to connect them
to chassis ground.
The optical subassemblies are
each attached to their respective
transmit or receive electrical
subassemblies. These two units
are then fitted within the outer
housing of the transceiver that is
molded of filled nonconductive
plastic to provide mechanical
strength. The housing is then

Agilent’s HFCT-5963xxx fiberoptic transceivers are designed
to couple to +3.3 V PECL signals.
The transmitter driver circuit
regulates the output optical
power. The regulated light output

The HFCT-5963xxx have a
transmit disable function which is
a single-ended +3.3 V TTL input
which is dc-coupled to pin 8.
As for the receiver section, it is
internally ac-coupled between
the preamplifier and the postamplifier stages. The actual Data
and Data-bar outputs of the postamplifier are dc-coupled to their
respective output pins (pins 4, 5).
The two data outputs of the
receiver should be terminated
with identical load circuits.
Signal Detect is a single-ended,
+3.3 V TTL output signal that is
dc-coupled to pin 3 of the
module. Signal Detect should not

Power Supply Filtering and Ground
Planes
It is important to exercise care in
circuit board layout to achieve
optimum performance from these
transceivers. Figures 6a and 6b
show the power supply circuit
which complies with the small
form factor multisource
agreement. It is further
recommended that a continuous
ground plane be provided in the
circuit board directly under the
transceiver to provide a low
inductance ground for signal
return current. This
recommendation is in keeping
with good high frequency board
layout practices.

with the circuit board “Common
The HFCT-5963xxx is
intrinsically eye safe and does
not require shut down circuitry.
Eye Safety Circuit
For an optical transmitter device
to be eye-safe in the event of a
single fault failure, the transmitter must either maintain eye-safe
operation or be disabled.
Signal Detect
The Signal Detect circuit
provides a deasserted output
signal when the optical link is
broken (or when the remote
transmitter is OFF). The Signal
Detect threshold is set to
transition from a high to low
state between the minimum
receiver input optical power and
-45 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). The
Signal Detect does not detect
receiver data error or error-rate.
Data errors can be determined by
signal processing offered by
upstream PHY ICs.
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. Agilent
has designed the HFCT-5963xxx
to provide excellent EMI
performance. The EMI
performance of a chassis is
dependent on physical design and
features which help improve EMI
suppression. Agilent encourages
using standard RF suppression
practices and avoiding poorly
EMI-sealed enclosures.
Agilent’s OC-3 LC transceivers
(HFCT-5963xxx) have nose
shields which provide a
convenient chassis connection to
the nose of the transceiver. This
nose shield improves system EMI
performance by effectively
closing off the LC aperture.

LC SFF Cleaning Recommendations
In the event of contamination of
the optical ports, the
recommended cleaning process is
the use of forced nitrogen. If

Regulatory Compliance
The Regulatory Compliance for
transceiver performance is
shown in Table 1. 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.
The second case to consider is
static discharges to the exterior of
the equipment chassis containing
the transceiver parts. To the extent
that the LC 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.
Electrostatic Discharge (ESD)
There are two design cases in
which immunity to ESD damage
is important.
Electromagnetic Interference (EMI)
Most equipment designs utilizing
these high-speed transceivers
from Agilent will be required to
meet FCC regulations in the
United States, CENELEC
EN55022 (CISPR 22) in Europe
and VCCI in Japan. Refer to EMI
section (page 9) for more details.
The first case is 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.
Immunity
Transceivers will be subject to
radio-frequency electromagnetic
fields following the IEC 61000-4-3
test method.
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 foreseeable single
fault conditions per EN60825-1.
Agilent 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 60825-2
applications. Their performance
enables the transceivers to be
used without concern for eye
safety up to 3.5 V transmitter VCC.

Absolute Maximum Ratings (HFCT-5963xxx)
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter in
isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that limiting
values of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum ratings for
extended periods can adversely affect device reliability.

Notes:
1. The output power is coupled into a 1 m single-mode fiber. Minimum output optical level is at end of life.
2. The relationship between FWHM and RMS values for spectral width can be derived from the assumption of a Gaussian shaped spectrum which
results in RMS = FWHM/2.35.
3. These are unfiltered 10-90% values.
4. PIN represents the typical optical input sensitivity of the receiver. Sensitivity (P INMIN ) and saturation (PIN MAX) levels for a 2 23-1 PRBS with 72 ones
and 72 zeros inserted. Over the range the receiver is guaranteed to provide output data with a Bit Error Rate better than or equal to 1 x 10-10.
