14EH
14EH
FEATURES
- Two models, regular for wiring closets and Hardened for Industrial, AC and DC power
- Provides 100Mb Ethernet media conversion between twisted pair and fibre, FDX and HDX, with Link Pass-Through
- Supports IEEE 802.3u auto-negotiation on the RJ-45 port to enable an attached switch port to operate at 100Mb/s FDX for full fibre distance
- Available with fibre connectors for SC, ST, LC, or MTRJ types, multi-mode, single-mode, or 40km “long reach” single mode
- Metal enclosure. Panel mounting, DIN-Rail or Rack-mount tray option
All fibre media types, robust packaging, a selection of extended temperatures, choice of AC and DC power types, ease-of-use features, and energy efficiency are the primary features of the 100 Mb 14E and 14EH Media Converters.
The 14E regular-package units are for wiring closet environments and offer the choice of external AC power supplies for either 0° to 40°C or the more stressful industrial 0° to 50°C ambient temperature. A heavy duty metal case with convection cooling is featured. The 14EH Hardened units feature a sealed metal case which is also used as a heat sink. No internal air flow is required for cooling, so the 14EH resists dust, dirt, moisture, smoke and insects, and is rated for above-the-ceiling “plenum” applications. Choices of models for use with external AC or internal DC power are available. Ambient temperature rating is up to –40°C to +75°C depending on the power source used. The 14EH is suitable for temperature un-controlled “outdoor” applications. Mounting options include stand-alone panel-mounting, DIN-rail, or rack-mount tray.
All models supports both full and half-duplex mode via auto-negotiation so that an attached auto-negotiating RJ-45 switch or hub port operates at its highest performance level. A manual AN/reg switch allows the user to select auto-negotiation, and then the Media Converter transmits applicable auto-negotiation Fast Link Pulses (FLPs) to the attached device at LINK-enable. Operation on both the copper port and the fibre port is at 100 Mb F/H transparent in any case, providing support for full length 100 Mb fibre media distances on all fibre types. The Link Pass-Through feature is standard so that managed switches can “see through” the Media Converter for LINK indication that includes downstream cable segments. For the installer, a blinking LED on the fibre side shows fibre cable status.
The up-link switch on the TX port allows the unit to gracefully fit into any installation without crossover cables. All models come with two (2) sets of LED indicators, one set on the front for viewing convenience when the Media Converter is wall-mounted, and one LED set mounted in the end adjacent to the media ports for easy viewing when units are in a rack-mount tray. The 14E and 14EH Media Converters and other products are designed and manufactured in the USA and backed by a three-year warranty.
