Telephone fiber optic multiplexer

Telephone optical transceiver Telephone optical transceiver is a fiber optical transmission equipment ,which is used optical fiber to transmitte telephone over a long distance .This equipment adopt the design of VLSI super scale integrated circuit ,concise appearance ,easy to install and debug ,maintenance-free .This product applies to telecommunication corperations,troops,governments and enterprises. The HS-optel series telephone optical transceiver can transfer 4/8/16/30/46 channel telephone directly through optical cable .Adopting point to point method to construct a network ,supporting FXO,FXS 2/4 wire EM,2/4 wire audio,RS232,V.35,maganetic telephone,ethernet or others interface.The HS-optel series telephone optical transceiver adopt special digital multiplexer chip ,it is powerful ,and can integrated all the function of digital integrated circuits together which not noly improve the performance of the product substantially,but also reduce the cost. This equipment have many advantages,including excellent performance,work reliably,low power consumption,high integration level ,small volume ,easy to install and maintain .In addition,the equipment support the function of CID(caller indentification)and fax .
