Four-Channel Pluggable Parallel Fiber Optic Transceiver
Data Sheet
Description
The HFBR-7934Z 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 3.125 Gb/s 8B/10B encoded per channel
providing a cost effective solution for very
short reach applications requiring 12.5 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-7934Z 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.
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.
