Safecom SA-OPFN Series Mini Optical Node is a state of the art two way optical platform which enables operators delivering video (digital or analog) and high-speed data services through advanced HFC network , it features 
high performance but low costs, offering an economic but effective solution for the last mile of the cable network. This OFN node features low distortion, flexible input level, temperature compensation for the gain, low power consumption, 6KV surge protection and working for long time constantly without failure. OFN Series offer full range of 5-1000MHz bandwidth, with flexibility in choice of wavelength, laser type and band splits for maximum application, support what DOCSIS3.0 requires a wider bandwidth at the return path. WDM models of OFN Series make it available for one fiber transmission.
