250-MBd Compact 650-nm Transceiver for Data Communication over Polymer Optical Fiber (POF) Cables with SMI Connector

Currently Viewing:

The Broadcom AFBR-59SMI2Z transceiver provides system designers with the ability to support serial communication with baud rates of up to 250 MBd over 2.2-mm jacketed standard polymer optical fiber (POF) with 1-mm core diameter and NA 0.5.
The SMI optical interconnect with its push-pull positive latching, with safe-release mechanism, provides secure, safe and easy to mate and de-mate optical connection for miscellaneous industrial and medical applications.
The AFBR-59SMI2Z is Laser Class 1, lead-free and compliant with RoHS.
