Applications

The primary function of a Magnum 14E Media Converter is to permit two different

media types to coexist within the same network by allowing data to be transmitted / received

between different media types.  Magnum 14E media converters provides an effective solution for

a network environment where auto-negotiation is a primary concern for the attached devices.

They also support 100Mb half duplex or full duplex mode, transparent.  Because of its auto-

negotiation feature, the Magnum 14E supports an attached “N-way” auto-negotiating RJ-45

switch or hub port, allowing it to operate at its highest performance level, i.e., full-duplex

100Mb/s. 

Magnum 14Es are typically used where new 10/100Mb switches or switching hubs with

auto-negotiating RJ-45 ports are being installed, and where full-duplex fiber segments (of up to

2Km for multi-mode or 25Km to 40Km for single mode) are needed
