HFBR-2526

The 125 MBd Versatile Link (HFBR-0507 Series) is the most cost-effective fiber-optic solution for transmission of 125 MBd data over 100 meters. The data link consists of a 650 nm LED transmitter, HFBR-15X7, and a PIN/preamp receiver, HFBR-25X6. These HFBR-25X6  can be used with low-cost plastic or silica fiber. One mm diameter plastic fiber provides the lowest cost solution for distances under 25 meters. The lower attenuation of silica fiber allows data transmission over longer distance, 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-15X7 transmitter is a high power 650 nm LED in a low cost plastic housing designed to efficiently couple power into 1 mm diameter plastic optical fiber and 200 mm Hard Clad Silica (HCSF) fiber. With the recommended drive circuit, the LED operates at speeds from 1-125 MBd. The HFBR-25X6 is a high bandwidth analog receiver containing a PIN photodiode and internal transimpedance amplifier. With the recommended application circuit for 125 MBd operation, the performance of the complete data link is specified for of 0-25 meters with plastic fiber and 0-100 meters with 200 mm HCSF fiber. A wide variety of other digitizing circuits can be combined with the HFBR-0507 Series to optimize performance and cost at higher and lower data rates.
