The OPF345 series fiber optic transmitters are high performance devices packaged for data communication links. This trans-

mitter is an 850 nm 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 de-

signer 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 inte-

gration into all types of data communications equipment.

Applications

♦ Industrial Ethernet equipment

♦ Copper-to-fiber media conversion

♦ Intra-system fiber optic links

♦ Video surveillance systems
