PDH Optical Multiplexer
1) Product Overview
PDH optical multiplexer is a kind of point-to-point optical transmission equipment developed by our company on the core of large-scale integrated circuit chips. It is applicable to remote transmission of switches, and small/medium-capacity applications transmitted over fibers, including mobile communication base stations, wireless local communication base stations and paging stations. The equipment features perfect overall performance, stable and reliable operation, low power consumption, high integration, small size and easy installation and maintenance. It is intended for carries and such fields as post and telecommunications, electrical power, railway, water resources, oilfields, and banks.
2) Main Features
• NT240B+/NT480B+ adopts two integrated media converter modules operating in active/standby mode (optional);
• Providing 4 to 16 E1 (2.048KB/S) interfaces and one wire speed 10/100M adaptive Ethernet interface;
• Full duplex/half-duplex adaptive operating mode;
• Full digital clock recovery and smooth phase lock technology;
• The code pattern of the E1 interfaces is HDB3 code, and the E1 jitter tolerance, transfer characteristic and output jitter completely meet the ITU-T G.703, G.823 and G.742 protocol.
• One PCM, without occupying 2M channel for transmission;
• Providing a user RS232 transparent data channel, and supporting unified network management;
• Providing perfect alarm and indication signals as well as alarm mask functions, using LED to display local and remote alarms and general alarms, capable of controlling remote loopback;
