OP-2Eth Fiber optical modem

 OP-2Eth

Function: transmit the signal between Ethernet interface and optical interface.

          It is a high-performance, self-learning distant Ethernet

Bridge with small size and low cost, which makes it suitable for cost-sensitive bridge connection as the LAN stretcher or separator based on the bite flow. It can study MAC destination address from the connected LAN constantly and determine whether forward or filter according to destination Mac address of data frames.

               The desk device and the rack share the same equipment; the rack has slots for 15 pieces of cards and two power cards with heat backup function.

3. Features

1.     Voltage select: desktop supports both AC200V and DC -48V; mounting rack: AC200V or DC -48V can be available with heat backup and support mixed insertion different cards.

2.     Ethernet interface has five kinds of work modes: 10M half duplex, 10M full duplex, 100M half duplex, 100M full duplex and auto-negotiation.

3.     Ethernet interface supports cross connection and direct connection cable.

4.     it can support 2 Ethernet interfaces at most which have exchanging function.

5.     Ethernet interface has channel isolation function.

6.     The desk and rack style share one board.

7.     cooperate with OP-4E1, 4E1-2Eth and can manage all the network in the 4E1-2Eth side.
