RPM-GS16E Gigabit Ethernet and 16 E1s to fiber multiplexer

Overview

The RPM-GS16E is designed as point to point optical transmission system based on
Application Specific Integrated Circuit (ASIC). It integrates the traditional PDH multiplexer and 1000Mbps Ethernet optical transceiver, and can realize the 16 E1s and one 1000Mbps wire-speed Ethernet transmission over fiber.
It not only provides dual hot-pluggable optical interfaces to realize 1+1 optical protection,but also integrates one RS232 auxiliary channel and one Engineering Order Wire (EOW) channel. Furthermore, it owns many humanize functions, such as Automatic Laser
Shutdown (ALS), Remote Power down Detect (RPD) and so on.
It supports the management based on Command Line Interface (CLI). With the supper 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.

Features

Realizes up to 16 E1s and one 1000M wire-speed Ethernet mixed multiplexing to optical fiber

Optical interface
Provides dual optical interfacesMSA(INF-8074i), ITU-T G.695, FC-PI V2.0 standards compliable, therefore hot pluggable is supported
Support 1+1 protection and Automatic Protect Switch (APS) with the recovering time less than 50ms
The line bit rate is 1.25Gb/stransmission distance is 30Km by default, and 80Km/120Km selectableoptical loop-back function, a great convenience for trouble shootingfunction supportableRemote Power down Detect (RPD) function, which can be used to distinguish the failures of remote power down or fiber broken

E1 interface
Provides up to 16 E1 interfaces, compliant to G.703, and balanced/unbalanced selectable Jitter tolerance, jitter transfer characteristic and jitter generation fully comply withG.823 and G.742 recommendationsloop-back function supported

Ethernet interface
Provides an Ethernet channel with up to 1000Mb/s bandwidthto IEEE 802.3, IEEE 802.3u, IEEE 802.ab, IEEE 802.3x recommendationsauto-negotiation function, and can works in 10M full/half duplex, 100M full/ half duplex, 1000M full duplex mode (1000M half duplex is not support)
Proprietary technique (patent pending) adopted to prevent Ethernet frames from looping back in case of unexpected optical loop-back
