GarrettCom 10Mb TF14 and TB14 Media Converters


Family of fiber models provides media (multi-mode and single-mode; transparent half-duplex and full-duplex) flexibility in installation and operations.

Install easily - simply attach cable segments to appropriate connectors on converter. An up-link switch on the RJ-45 port is included

TB14 BNC model provides an internal BNC termination switch, and operates with collision detection and indication

Provide diagnostic and network status information at a glance through a full set of LEDs

Rack-mount tray option (MC14-TRAY) available


Small physical size, rugged packaging, ease-of-use features, energy efficiency, and low cost are the primary characteristics of the Magnum 10Mb TF14-series and TB14 Media Converters.

Models are available for RJ-45 to fiber (all types) or RJ-45 to BNC media combinations, offering a graceful way to convert and transmit data between twisted pair and fiber or thin coaxial network cables for media flexibility in new or expanded 10Mb Ethernet networks. They cost significantly less than full repeaters and can be used whenever media distance limitations are not restrictive. The TF14 fiber models provide transparent half-and full-duplex operating mode.

The TB14 BNC model provides standard collision detection and indication. All units are compatible with Ethernet V1.0 / 2.0 specifications and comply with IEEE 802.3 standards. Magnum TF14 and TB14 Media Converters are designed for quick and easy installation even in very tight spaces. An up-link switch on the RJ-45 port provides manual crossover selection. The compact units, which are about the same size as traditional mini-transceivers, can be mounted securely on a closet wall or the side of cabinet, or by using the metal mounting clips included.

A rack-mount tray option is available, for up to 16 units. Magnum TF14 and TB14 Media converters are designed to provide low-temperature operation over an extended period to make them some of the most reliable in the industry. Their high-strength fabricated metal packaging shields against Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI).

Like all Magnum Ethernet connectivity products, they are designed and manufactured in the USA and are backed by a three year warranty.
