The an-fm-480/eth is a fiber media transport for 8e1 x e1 + 1 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. When the an-fm-480/eth is linked to the an-ch02 with an-fm-480/eth card, it allows network engineers to get greater functionality through advanced snmp features, the network administrator can manage any converter module from anywhere on the network, detect any link loss and maintain each loop. Features Can provide up to 16 e1 channels transmission transparently and 1 10/100m ethernet data channel. Provide 1 ethernet interface (support vlan, flow control, and self- negotiation, full/semi duplex,10m/100m optional) Local device monitor remote device (2 row leds, upper indicate local status, lower indicate remote status) Provide function of 16 e1 remote loop, fiber local loop, and 1 interface of phone. Power supply option: Ac220v, dc-48v, dc+24v (optional). Transmission distance:2-120 km Two fiber two direction and single fiber two direction (optional). Match telecom operation requirement, mtbf above 70,000 hours. High reliability, provide install type of 19 inch rack, desktop, hanging, and card, rack support both DC and AC power supply. Provide snmp function.
