PCMMultiplexer 4E1+10/100M+15FXS/FXOoptical multiplexer 4E1+10/100M+30FXS/FXOoptical multiplexerOP-4E1*ETH*nVO transfer 4E1, 1 10/100M Ethernet as well as 15 or 30 telephones FXS/FXO signals over fiber optical. Functions: OP-4E1*ETH*nVO Voice Optical Multiplexer is an optical transmission equipment realizing long-distance voice transmission through fiber. This equipment uses design of ultra large scale integrated circuit, and its outward appearance is succinct. The merits include easy installation and debugging, unnecessary for maintenance and steady performance. It is suitable in business for communication operator, government and kinds of entities with less investment.OP-4E1*ETH*nVO can provide 1-15 channels, or 1-30 channels telephone through optical fiber, the network application is point-to-point, supporting FXO/FXS. It has solved telephone transmission problem of edge customers. This equipment works stable and reliable and has good performance such as low power consumption, high integration rate, small volume and easy for installation and maintenance. Technical parameters1.
