Twelve-Channel Transmitter and Receiver
Pluggable, Parallel-Fiber-Optics Modules
Data Sheet
Description
The AFBR-775BxxxZ Twelve-Channel, Pluggable, Parallel-
Fiber-Optics Transmitter and AFBR-785BxxxZ Twelve-
Channel, Pluggable, Parallel-Fiber-Optics Receiver are
high performance fiber optics modules for short-range
parallel multi-lane data communication and interconnect
applications. The modules operate at 5.0Gbps per channel
over multimode fiber systems using a nominal wave-
length of 850 nm. Aggregate bandwidth per transmitter-
receiver link is 60G. The electrical interface uses a 10x10
MEG-Array® low-profile mezzanine connector. The optical
interface uses a MTP® (MPO) 1x12 ribbon cable connector.
The thermal interface can be a factory installed heatsink
for air-cooled systems or thermal seating plane for user
flexibility. The modules incorporate high performance,
highly reliable, short wavelength optical devices coupled
with proven circuit technology to provide long life and
consistent service.
Applications
