描述 Description

The HFBR-0508 Series consists of a fber-optic transmitter and receiver operating at a 650 nm wavelength (red). The HFBR-1528 transmitter is an LED in a low cost plastic housing designed to effciently couple power into 200 μm diameter HCS and 1 mm diameter POF. The HFBR-2528 receiver incorporates a PIN detector and digital output IC compatible with CMOS and TTL logic families.

特性 Features

? Data transmission at signal rates of dc to 10 MBd

? Up to 50 meters distances with 1 mm Plastic Optical Fiber (POF)

? Up to 500 meters distances with 200 μm Hard Clad Silica (HCS?)

? Wide dynamic range receiver allows operation from zero to maximum link distance with a single transmitter drive current

? Link distances specifed for variations in temperature, power supply, and fber attenuation

? DC coupled receiver with CMOS/TTL output for easy designs: no data encoding or digitizing circuitry required

? Pulse width distortion controlled to limit distortion from low duty cycle or burst mode data

? High noise immunity

? Compatible with Avago’s Versatile Link family of connectors, for easy termination of fber
