2.2 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 transmit data among twisted pair, thin 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.

Magnum Media Converters are designed for quick and easy installation even in
very tight spaces. Media cables are easily attached to the corresponding Media
Converter. Because of their compact size, Magnum Media Converters can be Velcro®-
mounted on an office wall or the side of a desk or cabinet. The external power supply
plugs into a nearby AC wall socket or power strip. Each converter features a full set of
LEDs that convey essential diagnostic and status information. See Section 4.1, LED
Indicators, for specific LED function information.
Magnum 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).

Magnum Media Converters are specifically designed to convert data signaling
to allow transmission between two different Ethernet cabling types, allowing migration to
a new media type while preserving segments of the pre-existing wiring structure.
All of the Magnum Media Converters comply with the IEEE 802.3 10BASE-T
specification for 10 Mb/sec traffic via shielded (STP) or unshielded twisted pair (UTP)
segments. The Media Converters feature an up-link or cross-over switch to eliminate the
need for a special cross-over cable when connecting to a hub or concentrator.
Note: experience shows that the maximum number of 10Mb Media Converters
that can be used in series is three. The cumulative noise from 4 or more units together
causes packet alignment errors.
