AFBR-77D2SZ, AFBR-78D2SZ
12.5 Gbps/Channel
Twelve Channel
Parallel Fiber Optics Modules
Product Brief
Description
The AFBR-77D2SZ Twelve Channel, Pluggable, Parallel Fi-
ber Optics Transmitter and AFBR-78D2SZ Twelve Channel,
Pluggable, Parallel Fiber Optics Receiver are high perfor-
mance fiber optics modules for short-range parallel multi-
lane data communication and interconnect applications.
The high density optical modules are designed to oper-
ate over multimode fiber systems using a nominal wave-
length of 850 nm.
The optical interface requires the user to provide a cus-
tom designed optical turn 1×12 ribbon cable PRIZM
LightTurn
connector.
