The Avago AFBR-821vx3Z is a 12-channel pluggable, parallel fiber optics receiver module device that supports 12x10G bandwidth with OM3 link distance up to 300 meters. The AFBR-811vx3Z and AFBR-821vx3Z are a Tx/Rx module pair optimized for short-range parallel multi-lane data communication and interconnect applications. The high density optical modules are designed to operate over multimode fiber systems using a nominal wavelength of 850 nm. These MiniPOD devices can support 300m 10GBASE-SR with Avago SFP+ transceivers over OM3 fiber. Avago’s MiniPOD solution offers system designers two module package options to optimize their cable management and board layout. The AFBR-811RxyZ Tx and AFBR-821RxyZ Rx are used with round multi-lane cable assemblies for applications requiring multiple turns of the jumper cable inside the chassis. The AFBR-811FxyZ Tx and AFBR-821FxyZ Rx are 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
http://portal.fciconnect.com/Comergent//fci/drawing/55714.pdf 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 accept either a user provided heat sink or Avago's general purpose clip on heat sink to maintain the module case temperature between 0 °C and 70 °C during continuos operation.
