Optical Modem Introduction:  The SPC-30AV fiber optical modem converts a V.35 electrical signal into an optical signal. After the conversion, the signal is transmitted over fiber optic cable, extending the V.35 service range up to 120 km. It is designed to provide a cost-effective point-to-point solution for extending the transmission distance and improving the transmission reliability of V.35 traffic. It converts V.35 electrical signal into optical data stream for transport. This fiber optic modem is developed for long distance and secure data link between data communication devices like routers, multiplexers and etc.  Features:Extends the range of equipment with electrical V.35 interface over fiberIn-band management of both local and remote unitsV.35 interface supports DCE/DTE modeV.35 interface supports local and remote loop-back functionCan be connected to SPC-30A or other SPC-30AV unitSupports single mode or multimode fiberOptional dual-strand fiber and single-strand fiber (WDM technology)
