Description

The AN-FM-240/480-GETH-SNMP is optical transmission equipment based on Application Specific Integrated Circuit (ASIC). It integrates the traditional PDH multiplexer and 1000Mbps Ethernet optical transceiver, and can realize the 8/16 E1s and four 1000Mbps Ethernet data channel transmission over optical line of 1.25Gb/s, the four 1000Mbps Ethernet data channel share 1000M bandwidth.

In point-to-point mode, the Ethernet transmission bandwidth can be doubled to 2.5G by setting the port-trunking function.

The AN-FM-240/480-GETH-SNMP is designed as a modular system with several optional E1 cards and power cards to meet the various application requirements. It provides one optical Gigabit Ethernet interface (SFP optical module) and three electrical Gigabit Ethernet interfaces (RJ45 connector) compliant with IEEE802.3 serial standard.

It provides dual hot-pluggable optical interfaces to realize 1+1 optical protection, furthermore, it owns many humanize functions, such as Automatic Laser Shutdown (ALS), Remote Power down Detect (RPD), prevent Ethernet frames from looping back in case of unexpected optical loopback and so on. 

It supports the management based on Command Line Interface (CLI). With the super terminal integrated by PC, user can realize the monitor and configuration of the device. It also supports Simple Network Management Protocol (SNMP).

With low power consumption, high integration and well stability, it is a cost-competitive solution for the application where gigabit Ethernet and E1 are required simultaneously, such as the telecommunication, the electric power and the finance fields.
