the full/half-duplex 100base-fx transceiver provides low cost and high performance network migration  options. features性质 connects mii nodes via an st or sc type  connector, to a fiber optic medium in both  full and half-duplex modes. (the ability to  operate in full-duplex mode allows for  operation between switches and routers using  full-duplex fast ethernet.)  support fiber optic segments up to 2,000  meters on multimode fiber.  single mode version supports fiber optic  segments up to 20,000 meters.

applications 应用

extend network distances: 
extend connection distances between hubs or switches and workstations
 by incorporating fiber optic technology into your network. 

increase your network"s flexibility:
increase the type of components and vendors you can use by providing
 the needed interface for new devices. for example, maintain
 full-duplex fast ethernet connections between wan routers with
 full-duplex capable mii and full/half-duplex ethernet switches.
