Optic Transceivers. HFCT-53D5 Datasheet
HFBR-53D5 Family, 850 nm VCSEL
HFCT-53D5 Family, 1300 nm FP Laser
1 x 9 Fiber Optic Transceivers for Gigabit Ethernet
The HFBR/HFCT-53D5 transceiver from Avago
Technologies allows the system designer to implement
a range of solutions for multimode and single mode
Gigabit Ethernet applications.
The overall Avago Technologies transceiver product
consists of three sections: the transmitter and receiver
optical subassemblies, an electrical subassembly, and
the package housing which incorporates a duplex SC
The transmitter section of the HFBR-53D5 consists of
an 850 nm Vertical Cavity Surface Emitting Laser
(VCSEL) in an optical subassembly (OSA), which mates
to the fiber cable. The HFCT-53D5 incorporates a 1300
nm Fabry-Perot (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.
The receiver of the HFBR-53D5 includes a silicon 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 post-amplification and quantization. The
HFCT-53D5 utilizes an InP PIN photodiode in the same
configuration. 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 W PECL load.

Package and Handling Instructions
Electrostatic Discharge (ESD)
The HFBR/HFCT-53D5 transceiver housing is made of
high strength, heat resistant, chemically resistant, and
UL 94V-0 flame retardant plastic.
Recommended Solder and Wash Process
The HFBR/HFCT-53D5 is compatible with industry
standard wave or hand solder processes.
This transceiver is supplied with a process plug (HFBR-
5000) for protection of the optical ports within the
duplex SC connector receptacle. This process plug
prevents contamination during wave solder and
aqueous rinse as well as during handling, shipping and
storage. It is made of a hightemperature, molded
sealing material that can withstand 80°C and a rinse
pressure of 110 lbs per square inch.
Recommended Solder fluxes Solder fluxes used with
the HFBR/HFCT-53D5 should be water-soluble, organic
fluxes. Recommended solder fluxes include Lonco
3355-11 from London Chemical West, Inc. of Burbank,
CA, and 100 Flux from Alpha-Metals of Jersey City, NJ.
Recommended Cleaning/Degreasing Chemicals
Alcohols: methyl, isopropyl, isobutyl.
Aliphatics: hexane, heptane Other: soap solution,
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, HP does not recommend the use of cleaners that
use halogenated hydrocarbons because of their
potential environmental harm.
(See the Regulatory Compliance Table for transceiver
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.
There are two design cases in which immunity to ESD
damage is important. 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. The
transceiver performance has been shown to provide
adequate performance in typical industry production
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
Electromagnetic Interference (EMI)
Most equipment designs utilizing these high-speed
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.
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.
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 EN60825-1.
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 certi-fication 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.
