Giới thiệu
AN-FM-120-4ETH series of Multi E1 & Fast Ethernet Optical Terminal is a product combining of a PDH optical transport system and an Ethernet transceiver.
AN-FM-120-4ETH can provide up to 8 E1 interfaces and 4 Fast Ethernet interface. The Ethernet interface can be operated in 10M/100M, half duplex or full duplex mode by either auto-negotiation or manual setting.
The AN-FM-120-4ETH is a fiber media transport for 8E1 + 4 x 10/100BaseT transmission. The BNC model provides unbalanced 75 Ohm coaxial connections while the RJ-45 model provides balanced 120 Ohm connections over twisted pair wiring.
All media converters are available with either multi-mode or single-mode optical tranceivers and with connectors for SC, ST, or FC. In single mode they are available in up to 120 km versions reach, which will provide the ability to transmit and receive data using only a single optical fiber pair.
AN-FM-120-4ETH provides an order-wire for which a standard telephone can be used.
AN-FM-240-4ETH provides a user RS232 transparent data link with a RJ45 connector.
AN-FM-120-4ETH possesses complete operation monitoring function. Those indicators include Loss of optical signal, LOF, 10-3, 10-6 bit error rate, Loss of each E1 tributary signal and Ethernet status. Since some overhead bytes are taken as monitoring channel, all alarm and status of Remote can be display locally.
AN-FM-120-4ETH provides RS232 interface for Network Management. Supported by AN-NM-PDH GUI network manager utility, users can observe the status of Local and Remote, as well as other alarm information unable to be displayed by LEDs in the front panel. Also, with AN-NM-PDH, user can make certain E1 loop back for testing purpose.
4 x 10/100 Ethernet ports support intelligent Layer 2 switch features, such as QoS, dot1Q and port based VLAN’s, flow control per port with steps n x 32 Kbit/s and more.
