ERM12N

100BaseTX to 100BaseFX Media Converter Card

ERM12N | Rack Mount

Documentation

  • ERM12N Data Sheet PDF

Overview
Model ERM12N, 100BaseTX to 100BaseFX media converter card, is designed to allow the network designer to add fiber segments as needed. It is designed to fit into ERM21C, 21 slot chassis.

Features & Benefits

  • Converts 100BaseTX to 100BaseFX and vice-versa
  • Allows for the introduction of a fiber segment to: greatly increase segment length, eliminate electro-magnetic interference, and offers protection from lightning
  • Multimode configuration standard, the optional single mode can increase fiber segment lengths from 2 Km. to 50 Km.
  • MDI/MDIX switch on 100BaseTX side of converter
  • Compact rugged steel faceplate
  • Half duplex/full duplex
  • Designed & manufactured in the USA

Description
ERM12,100BaseTX to 100BaseFX media converter, allows 100BaseTX specifications to be used over fiber cable.

Designed to meet the needs of today’s network planers to marry the Fast Ethernet performance with the benefits of fiber segments, The ERM12 media converter complies with the 100BaseTX 802.3u standard.

A complement of 6 LEDs display power for the unit plus link and receive on each segment.

The 100BaseTX side of the unit features a MDI/MDIX crossover switch that dispenses with the any need for specially configured cables.
