HFBR-7924WZ
Four-Channel Pluggable Parallel Fiber Optic Transceiver
Part of the Avago Technologies METRAK family
Data Sheet
Description
The HFBR-7924WZ transceiver is a high performance
fiber optic module for parallel optical data communica-
tion 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 wave-
length 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-7924WZ transceiver module incorporates a 4
channel VCSEL (Vertical Cavity Surface Emitting Laser)
array together with a custom 4 channel laser driver inte-
grated 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 connec-
tions to the device are achieved by means of a pluggable
10x10 connector array.
