16E1 Fiber Optical Transmitter and Receiver(16E1 PDH multiplexer)
Brief introduction
DLX-OP16 16E1 PDH Optical Transmitter and Receiver is PDH optical transmission equipment with high capability. Adopts especial CMOS chip, provides 16E1 digital signals multiple connection, branch connection and optoelectronic switching, realized the long-distance data transmission. Main channel is 16 E1/G.703 ports, offers one channel official telephone connection for the two stations communicate. RS232 low rate data channel, 1+1 Fiber back up, 1+1 redundant power supply,1~4 Ethernet channels and network interior management channel optional(Inside installation administration of network channel can be used to the network management domiciliary transmission and switching, and realize the remote monitoring of equipment.).
This product possess loop back function of the local end and the far end for test and fault location via set up DIP switch in the near end device. Possess perfect fault self-diagnostic function, supports optional Link-Loss alarm function, 2Mbit/s circuit alarm and sound alarm. Possess alarm sound and circuit shielded function. Adopts 16B5H line coding, transmission rate is 42.24Mbit/s, support Single-Strand bi-directional mode or Double-Strand bi-directional mode, meet the different demand of client.
It has high integration degree, high reliability, low power consumption, small in size and consummate function. Adapt to point to point optical transmission link circuit and provides public network and special network with high quality, flexible and reliable optical transmission digital line. It sits perfectly on the network client of telecom, mobile, electric power, police, petroleum and so on.
