12 Megabaud Versatile Link Fiber Optic Transmitter

Currently Viewing:

The HFBR-1525EZ transmitter is an LED in a low cost plastic housing designed to efficiently couple power into 200 μm diameter Hard Clad Silica (HCS®) and 1 mm diameter Plastic optical fiber (POF).
The HFBR-1525EZ/HFBR-2525EZ links operate from DC to 12 MBd at distances up to 50 meters with 1 mm POF and up to 500 meters with 200 μm HCS®. No minimum link distances are required when using recommended circuits, simplifying design.
Versatile Link components can be interlocked (N-plexed together) to minimize space and to provide dual connections with the duplex connectors. Up to eight packages can be interlocked and inserted into a printed circuit board.
