NXF-742MT: Enhanced 10/100Base-TX to 100Base-FX Multi-mode Converter (ST Connector)
 NXF-742MC: Enhanced 10/100Base-TX to 100Base-FX Multi-mode Converter (SC Connector)
   NXF-742SC: Enhanced 10/100Base-TX to 100Base-FX Single Mode Converter (SC Connector)

The NXF-742 Media Converter is a compact, cost-effective and feature-packed solution for expanding an existing Ethernet / Fast Ethernet network. For total reliability the converter boasts enhanced features such as remote and local loopback testing, auto-negotiation, and link-fault signaling. It also features seven DIP switches for manual activation of the enhanced features. This gives the NXF-742 the ability to be quickly integrated into a network configuration.

The NXF-742 can support a variety of fiber optic cables and connectors. Whether data is transmitted over multi-mode, single mode or long-haul single-mode fiber optics, or operating in full or half-duplex mode, the NXF-742 is capable of handling all the various cable-type configurations.

Main Features:

  • Ideal for Telco and Cable Network application
  • Extends distances ranging from 2km (multi-mode fiber) to 60km (single mode fiber)
  • NWay Auto-negotiation support on RJ-45 port
  • DIP switch manual setting on 10 or 100 and half or full duplex in case of auto-negotiation failure
  • Store-and-forward at full wire speed
  • Chassis compliant (internal power supply)
  • Auto MDI
  • Manual setting on speed and duplex for compatibility with non auto-negotiation devices
  • Link Fault Signaling LED illuminates to indicate link down
  • Device DIP switches allow multiple configuration options
  • Link Fault Signaling function can boot up redundant link if network is installed with primary and redundant link
  • Local and remote loopback test for first time installation and trouble-shooting
  • Available with external & internal power supply
  • FCC Class A & CE approved
