HFBR-7934Z and HFBR-7934EZ/HZ/EHZ
Four-Channel Pluggable Parallel Fiber Optic Transceiver
Data Sheet
Description
Features
The HFBR-7934Z transceiver is
a high
•
•
RoHS Compliant
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.
Four Transmit and Four Receive Channels; 1 to 3.125
