Detailed Product Description

AN-FM-120-4ETH is state-of-art 4 x E1 G.703 + 4 x Ethernet 10/100BaseT fiber multiplexer with logical bandwith control which allows effetive transmission of those protocols over fiber optical cable over distances more than 120 km. Single mode, dual mode and WDM (BiDi) versions

The AN-FM-120-4ETH is a fiber media transport for4E1 x E1 + 4 x 10/100BaseT transmission. The BNC model providesunbalanced 75 Ohm coaxial connections while the RJ-45 model providesbalanced 120 Ohm connections over twisted pair wiring.
All mediaconverters are available with either multi-mode or single-mode opticaltranceivers and with connectors for SC, ST, or FC. In single mode theyare available in up to 120 km versions reach, which will provide theability to transmit and receive data using only a single optical fiberpair.

When the AN-FM-120-4ETH is linked to the AN-CH03 or AN-CH02 with AN-FM-120-4ETH card,it allows network engineers to get greater functionality throughadvanced SNMP features, the network administrator can manage anyconverter module from anywhere on the network, detect any link loss andmaintain each loop.
