Fiber Optic Transmitter for 25 MBaud MOST

Currently Viewing:

AFBR-1013 Transmitter are designed to transmit up to 25MBit/s optical data which are biphase coded (up to 50Mbaud). They are packaged in 4-pin transfer molded, low-cost packages ready for assembly into MOST® plastic fiber optic connector receptacles.
The transmitter utilizes a 650 nm LED source with integrated optics for efficient coupling into 1mm Polymer Optical Fiber (POF).
Input data has TTL switching levels, compatible with MOST® Network Interface Controller ICs.
This optical components are specified for operation over a -40°C to +95°C temperature range, and reliability requirements of automotive applications.
It is allowed to process the AFBR-1013 devices with reflow soldering.
