ZyXEL SFP100FX2 Multi-Mode 100Base-FX SFP Transceiver follows industry standards to assure compatibility with switches from other manufacturers without barriers set by proprietary technologies. With ZyXEL's comprehensive Fast and Gigabit transceiver product range, users can just plug in the proper model to extend the physical network coverage. Independent transceiver design provides the highest network maintenance flexibility.
Transceivers can be added when required and infrastructure upgrade or transceivers repair can be done easily by just replacing the transceiver instead of the whole device. Two strands of fiber have been required for traditionally fiber optic networking to accomplish communications. In this case, one strand is reserved for transmitting, the other for receiving.
However, bi-directional, dual wavelength transceivers can accomplish communications over just one strand of fiber by using two separate optical wavelengths, one to receive and the other to transmit the signal. Transmission capacity can be expanded immediately without additional cost of running new fiber and the value of existing fiber plant can be maximized.
