FE1/10&100Base-T Bridge

Function of Product
FE1/10&100Base-T Bridge is designed based on ASIC chip, the chip adopts jitter reduced, digital phase locked and clock distilled, E1 anti-jamming technology. The inner software and hardware are of modular design, integrating coding, decoding, message insertion and alarm, and make the circuit simple so as to improve the reliability of the device.

FE1/10&100Base-T Bridge provides 64K~2M bandwidth data transmission channels for Ethernet over E1 lines, connects two LANs by PDH devices etc. It is suitable for many situations, such as LAN expansion, networks isolation, WAN access, it can connect Ethernet to telecom transmission network, special network or WAN.
