PDH Optical Multiplexer
PDH optical multiplexer is a kind of point-to-point optical transmission equipment developed based on ultra large scale integrated circuit. Have perfect alarm function, data office telephone optional, high reliability and stabilization, low power consumption, high integration, small bulk, easy installation and maintenance. The device is popularly with telecommunication operator. It is suitable in business for communication operator, government and kinds of entities.
PDH Multiplexer refers to design of highly integrated structure and provides 16 standard E1 interfaces together with one channel of order wire, with self-contained alarm and NM functions,as well as self-testing and E1 loop-back testing functions.Alarm signals are provided in a full range,including LOS,LOF,10-3 error code,and 10-6 error code alarms of line side as well as LOS and HDB3 coding violation alarms of E1 bypass,and available with sound alarming signals.All performances have been satisfactorily designed,so that it has become a steady and reliable NG transmission product,nice in appearance and delicate,economical and practical,with good transmission performance. Transmission impedance can be matched through simple contact pin and patch cord or DIP switch setting,and at the same time different adapters can be selected to adapt to different interfaces.The product can be applied to construct economical and flexible multi-service transmission networks,used for relay between switch offices,data transmission of LAN,2M access of lease service for key clients,voice cutover for residentical areas/intelligent buildings,and connection of base stations and other various digital transmission networks.
