Product Description

Magnum TF14 and TB14 10Mb Media Converters offer a compact, cost-effective
way to adapt to non-RJ-45 Ethernet cabling as network requirements change and grow.
The design provides units that are very small, power-efficient, but also full-function.

The “14” series offer a graceful way to convert and transmit data among twisted
pair, fiber and thin coaxial network cabling environments. A variety of twisted-pair-to­fiber models provide for multi-mode or single-mode, transparent full- and half-duplex
mode, and normal or Link Pass-through operation. Magnum TF14 and TB14 Media
Converters cost significantly less than full repeaters and can be used whenever media
distance limitations will not be exceeded in the segment. All units are compatible with
Ethernet V 1.0 / 2.0 specifications and comply with IEEE 802.3 standards.
