HFBR-7934WZ/EWZ/HWZ/EHWZ
Four-Channel Pluggable Parallel Fiber Optic Transceiver
Data Sheet
Description
The HFBR-7934WZ transceiver is a high performance fiber
optic module for parallel optical data communication
applications. It incorporates 8 independent data chan-
nels (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 pro-
vide long life and consistent service.
The HFBR-7934WZ 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 pack-
age with integral finned heatsink. Electrical connections
to the device are achieved by means of a pluggable
10x10 connector array.
