NXF-742 : Enhanced 10/100Base-TX to 100Base-FX Converter

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.

Features

‧ Automatic MDI/MDI-X selection on RJ-45 port
‧ Link Fault Signaling (LFS)
‧ Store-and-forward at full wire speed
‧ Auto-negotiation, NWay support
‧ Half / Full-duplex mode selection
‧ Remote and local loopback Test via DIP switch
‧ When DIP switches are set, the system auto-reboots
to new configurations without powering off.
‧ Extends distances to up to 2km (6600 feet) multi-mode
fiber and 60km (198000 feet) long-haul single mode fiber
‧ Compatible with other 10Base-T & 100Base-TX/FX devices
‧ LEDs for at-a-glance device status
‧ Suitable as stand-alone or in a 19" 4 or 12-slot rack-mounted
converter chassis or in a single-slot mini chassis (with internal power supply)
‧ FCC Class A & CE approved
