The AN-FM-240/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 fober modems 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-240/ETH is linked to the AN-CH03 with AN-FM-240/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. - Can provide up to 8 E1 channels transmission transparently, and 1 10/100M Ethernet data channel. - Provide 1 Ethernet interface (support VLAN, flow control, and self- negotiatio, 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 8 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. The rack support both DC and AC power supply. Provide SNMP function, MIB\'\'s for your SNMP third party platform - everything you you need for your E1 transmission! All other type and configuration multiplexers are available on request. You can choose single fiber WDM,16 port E1 or even E1 + V.35 + 30 POTS for tributaries, all is possible by using our fiber products!
