Data Sheet
Description
The AFBR-776BxxxZ Twelve-Channel, Pluggable, Parallel-
Fiber-Optics Transmitter and AFBR-786BxxxZ 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 6.25Gbps per chan-
nel over multimode fiber systems using a nominal wave-
length of 850 nm. Aggregate bandwidth per transmitter-
receiver link is 75G. 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.

for expanded functionality including:
o Individual channel functions: disable, squelch
disable, lane polarity inversion, margin
o Programmable equalization integrated with DC
blocking caps at transmitter data input
o Programmable receiver output swing and de-
emphasis level
o A/D readback: module temperature and supply
voltages, per channel laser current and laser power,
or received power
o Status: per channel Tx fault, electrical (transmitter)
or optical (receiver) LOS, and alarm flags
• 0 to 80 C case temperature operating range
