Fiber Optic Transmitter OPF340 Series Features: • Low Cost 850 nm LED technology • Herme� c metal can package • High thermal stability • High op� cal coupling efficiency to mul� mode Ţber • Industrial temperature range • 55 MHz Bandwidth Description: The OPF340 series Ţber op� c transmi�ers are high performance devices packaged for data communica� on links. This transmi� er is an 850 nm GaAlAs LED and is speciŢcally designed to efficiently launch op� cal power into Ţbers ranging in size from 50/125µm up to 200/300µm diameter Ţber. Mul� ple power ranges with upper and lower limits are offered which allows the designer to select a device best suited for the applica� on. This product’s combina� on of features including high speed and efficient coupled power makes it an ideal transmi� er for integra� on into all types of data communica� ons equipment. Applications: • Industrial Ethernet equipment • Copper-to-Ţber media conversion • Intra-system Ţber op� c links • Video surveillance systems Typical Coupled Power I = 100mA, 25°C F Fiber Size Type N.A.
