HFBR-7924E
Description
The HFBR-7924 transceiver is a
high performance fiber optic
module for parallel optical data
communication applications. It
incorporates 8 independent
data channels (4 for transmit
and 4 for receive) operating
from 1 to 2.7 Gb/s per channel
providing a cost effective
solution for very short reach
applications requiring 10.8 Gb/s
aggregate bandwidth. The
module is designed to operate
on multimode fiber systems at
a nominal wavelength of 850
nm. It incorporates high
performance, highly reliable,
short wavelength optical devices
coupled with proven circuit
technology to provide long life
and consistent service.
The HFBR-7924 transceiver
module incorporates a 4 channel
VCSEL (Vertical Cavity Surface
Emitting Laser) array together
with a custom 4 channel laser
driver integrated circuit
providing IEC-825 and CDRH
Class 1M laser eye safety. It also
contains a 4 channel PIN
photodiode array coupled with a
custom preamplifier / post
amplifier integrated circuit.

HFBR-7924E/H/EH Four-Channel
Pluggable Parallel Fiber Optic Transceiver
Part of the Agilent METRAK family
Data Sheet
Operating on 3.3 V power
supply this module provides
LVTTL/LVCMOS control
interfaces and CML compatible
high speed data lines which
simplify external circuitry. The
transceiver is housed in MTP®/
MPO receptacled package with
integral finned heatsink.
Electrical connections to the
device are achieved by means of
a pluggable 10x10 connector
array.
