HFBR-1537Z

The 125 MBd Versatile Link (HFBR-0507Z Series) is the most cost-eff ective fi ber-optic solution for transmission of 125 MBd data over 100 meters. The data link consists of a 650 nm LED transmitter, HFBR-15X7Z, and a PIN/preamp receiver, HFBR-25X6Z. These can be used with lowcost plastic or silica fi ber. One mm diameter plastic fi ber provides the lowest cost solution for distances under 25 meters. The lower attenuation of silica fi ber allows data transmission over longer distance, for a small difference in cost. These com po nents can be used for high speed data links without the problems common with copper wire solutions, at a competitive cost. The HFBR-15X7Z transmitter is a high power 650 nm LED in a low cost plastic housing designed to effi ciently couple power into 1 mm diameter plastic optical fi ber and 200 µm Hard Clad Silica (HCS) fi ber. With the recommended drive circuit, the LED operates at speeds from 1-125 MBd. The HFBR-25X6Z is a high band width analog receiver con tain ing a PIN photodiode and internal transimpedance amplifi er. With the recommended application circuit for 125 MBd operation, the performance of the complete data link is specifi ed for of 0-25 meters with plastic fi ber and 0-100 meters with 200 µm HCS fi ber. A wide variety of other digitizing circuits can be combined with the HFBR-0507Z Series to optimize perfor-mance and cost at higher and lower data rates.
