OPF372 Family Features: Low Cost 850 nm LED technology Popular ST style receptacle Pre-tested with fiber to assure performance Component pre-mounted and ready to use 35MHz operation Description: The OPF372 family fiber optic transmitters are high performance devices packaged for data communication links. This transmitter is an 850nm GaAlAs LED and is specifically designed to efficiently launch optical power into fibers ranging in size from 50/125µm up to 200/300µm diameter fiber. Multiple power ranges with upper and lower limits are offered which allows the designer to select a device best suited for the application. This product’s combination of features including high speed and efficient coupled power makes it an ideal transmitter for integration into all types of data communications equipment. The mechanical design of this packaged is intended for PC Board or panel mounting. It is shipped with a lock washer, jam nut, 2 #2-56 screws, and a protective dust cap. Applications: Industrial Ethernet equipment Copper-to-fiber media conversion Intra-system fiber optic links Video surveillance systems Typical Coupled Power IF = 100mA, 25°C Fiber Size Type N.A.
