Project description:
            According to combination applications of the single E1 PDH,Ethernet PDH and Ethernet converter. The whole project is simple, decreased fault point,equipments investment,saved near half of the cost.

          fiber Modem also be called single port PDH,is a kind of three pcs and one set fiber transmit equipment which aims at special customer environment(three pcs and one set means one set ethernet or V.35 fiber modem,one set E1 fiber modem and a transducer).The equipment adopts large-scale integrate chip,the electric circuit is simple,power is low,the credibility is high,having complete alarm and perfect network management function.

           My company has already developed and produced single E1 PDH,single V.35 PDH and single ethernet PDH at present.These may be used mixed together,also may be use with related interface converter,and provide to plug-in card fiber Modem.
