100/1000Base-T to 100/1000Base-X SFP Managed Fibre Converter

The IMC-1000MS is an industrial grade electrical to optical media converter for Gigabit Ethernet. There are two models, one with fixed optical transceiver (1000M) and one supporting pluggable SFP transceiver (1000MS). These converters sport embedded stand-alone Web based management over IP networks as well as IEEE802.3ah OAM for remote in-band management.

The SFP slot supports a wide range of standard SFP modules to address any network situation. Single-mode, Multi-mode, Multi-rate, Dual Rate (100/1000), Single fibre bi-directional, Coarse and Dense Wave Division Multiplexing (CWDM and DWDM) and Copper media.

Management

Comprehensive features include bandwidth control, speed, VLAN, Diagnostic, storm filter and converter configurations. In addition, network administrators can manage IMC-1000MS via standard SNMP manager such as SmartView™. It also provide loop-back test and dying gasp, and can be monitored from a centrally located OAM- enabled FRM220-1000MS converter via remote in-band management.

Alarm  relay

A removable terminal block provides both power and alarm connections. Power can be provided through the dual inputs from separate sources. One electrical relay can be wired into an alarm circuit. From the common pin (COM), the relay can be connected as Normally Open (NO) or Normally Closed (NC). The alarm is triggered by programmable events of either link loss for optical or electrical or both. The relay is able to support a maximum current carrying capacity of 1A@24VDC.

 802.3ah OAM Functions

This converter supports IEEE 802.3ah, an OAM protocol that operates at Ethernet Layer 2 (Data Link layer). OAM provides mechanisms to monitor link operation / health and to improve fault isolation. OAM only works point-to-point over the fiber link. In addition to standard 802.3ah functions like loop back and dying gasp, IMC-1000MS also implements OAM to provide complete provisioning of the remote fibre connected converter, without using Layer 3 IP protocol. By using OAM, we can remote manage another fibre connected 1000M(S) converter, without IP addressing. From this menu we can also perform some basic diagnostics, such as loop back test.
