125 MBd Optical Transmitter for Industrial Applications

Currently Viewing:

Avago’s 125 MBd Robust Versatile Link Transmitter series offers a cost-effective fiber optic solution for transmission of 125 MBd data over 100 m. Our 125 MBd Robust Versatile Link Transmitter consists of an LED transmitter, HFBR-1527ETZ, and a PIN/preamp receiver, HFBR-2526ETZ. These can be used with low-cost plastic or silica fiber. Plastic fiber, with a 1 mm diameter, provides the lowest cost solution for distances under 25 m. The lower attenuation of silica fiber allows data transmission, over longer distances, for a small difference in cost. These components can be used for high-speed data links without the problems common with copper wire solutions, at a competitive cost.

The HFBR-1527ETZ 125 MBd Robust Versatile Link Transmitter is a high-power 650 nm LED in a low-cost plastic housing used to efficiently couple power into 1 mm diameter plastic optical fiber and 200 µm Hard Clad Silica (HCS®) fiber. With the recommended drive circuit, the LED operates at speeds from 1-125 MBd.
