The AFBR-77D4SZ and AFBR-78D4SZ are a set of 12-channel, pluggable, parallel fiber optics transmitter and receiver modules set optimized for short-range parallel multi-lane data communication and interconnect applications. These high-speed, high density optical modules are designed to operate over multimode fiber systems using a nominal wavelength of 850 nm.

The optical interface requires the user to provide a custom designed optical turn 1×12 ribbon cable PRIZM® LightTurn® connector.
