Name: 8 E1 + 100M PDH Optical multiplexer

8 E1 + 100M PDH oprical multiplexer focuses on the programmed logic devices and transmits the hybrid coded E1 and Ethernet signals in a pair of fibers.It has adopted the latest design techniques and ultra-large-scale programmable integrated circuits.It provides 32M transmission capacity for PDH optical transmission system,and realizes10/100M Ethernet and E1 business hybrid transmission.

Main features:

• 8 channels for E1 business interfaces,all- digital clock recovery and the smooth lock-in technology,large-scale programmable logic devices’ design make the replacement rate of this product much higher than that of traditional ASIC based optical transmitter and receiver.Support local/remote tributary jitter,particularly for high reliability requirements occasion,such as:mobile,China Union,telecommunications,electricity,highways,public security,military,aviation etc.private wire network.
• Optional SNMP network management
