Product Description

Magnum 10Mb Media Converters offer a compact, cost-effective way to adapt a
pre-existing Ethernet cabling configuration as network requirements change. They offer
a graceful way to convert and tran smit data among twisted pair, t hin coaxial and fiber
network cabling environments. A variety of twisted-pair-to-fiber models provide for
multi-mode or single-mode, full- or half-duplex, ST or SC connectors, and normal or
Link Pass-through operation. Magnum Media Converters cost significantly less than full
repeaters and can be used whenever media distance limitations will not be exceeded in
the new environment. All units are compatible with Ethernet V 1.0 / 2.0 specifications
and comply with IEEE 802.3 standards.
