High Speed Interconnects

The AFBR-811VxyZ and AFBR-821VxyZ are a set of 12-channel, pluggable, parallel fiber optics trasmitter and receiver modules 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.

Avago's MiniPOD solution offers system designers two module package options to optimize their cable management and board layout. AFBR-811RxyZ Tx/AFBR-821RxyZ Rx is used with round multi-lane cable assemblies for applications requiring multiple turns of the jumper cable inside the chassis. AFBR-811FxyZ Tx/AFBR-821FxyZ Rx is used with flat ribbon cable assemblies, allowing dense tiling of the modules as the jumper cables can be thread under the dust-cap of the next module. This top mounted optical connection maximizes board layout density by eliminating board space lost to the optical connector and strain relief.

The electrical interface uses a 9×9 MEG-Array connector with 1.27 mm pitch:

The optical interface requires the user to provide a custom designed optical turn 1×12 ribbon cable PRIZM^® LightTurn^® connector. The thermal interface provided can require either a user provided heat sink or use of the Avago general purpose clip on heat sink, to maintain the module case temperature to be between 0°C to 70°C.
