4FE Fiber Modem （Bandwidth 2M）

This device is the extension device of Ethernet, using network to achieve local and remote Ethernet interconnecting with serial interfaces at a lower cost. The device has inter-set loop test function to facilitate the project launching and daily maintenance.

● Based on self -copyright  IC

● The device can manage the remote device condition , OAM management data did not take up user’s timeslot

● The local device can forced the remote device rate follow it

● The Ethernet interface supports jumbo frames (2036 Bytes);

● Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering

● Optical Ethernet Interface supports 100M, full duplex

● 4Channel 10M/100M Ethernet interface can isolate each other to realize communication independently

● Have Ethernet monitor self-reset function, the equipment will not dead

● The local device can forced the remote device rate follow it(when the device is unframed mode, that is invalid)

● Support SNMP Network Management

● The device supports unframed mode (2048K) set, it can the remote device condition when unframed

● Ethernet interface supports 10M/100M, half/full duplex auto- adaptable, support VLAN

● Ethernet interface supports AUTO-MDIX (crossed line and straightly connected line self-adaptable )

● Can form the structure: ETH+E1 (A)－－-E1 Optical Fiber Modem(B)－－-Ethernet Fiber Modem (C)

● Fiber
