GarrettCom 100Mb 15E Media Converters


• Provides Fast Ethernet media conversion from twisted pair to fiber
• Available with fiber connectors for either SC or ST types, multi-mode or singlemode
• Full or half-duplex mode operation, transparent
• Complies with 100Mb/s Fast Ethernet standards, IEEE 802.3u
• Comes with a compact durable metal enclosure, has an external power supply 


Magnum™ 15E Media Converters offer a compact, cost-effective way to incorporate fiber media into a Category 5 TX-based Fast Ethernet network. They cost significantly less than full repeaters and do not use as much of the Fast Ethernet cable and repeater distance budget.

Each Magnum 15E transparently supports both half- and fullduplex operation, and can be used in any Fast Ethernet network application. The up-link switch on the Magnum 15Es TX port allows the units to gracefully fit into any installation, without crossover cables. When the Magnum 15E is used to convert a 100Mb/s RJ-45 shared or switched hub port to fiber media, the up-link switch is set to the “X” position. When the Magnum 15E is used to convert a fiber link to the RJ-45 port of a NIC card or workstation, the up-link switch is set to the “=” position. Category 5 twisted-pair cable should be used to connect to the TX port.

Separate LEDs indicate LINK status for each port, lighting when the associated cable segments are properly connected at both ends and are ready for data transmission. Collisions (if any) are not detected, and 15Es operate properly when connected to either FDX or HDX ports. 15Es do not respond to auto-negotiation FLP requests.

The Magnum 15E Media Converters meet the IEEE 802.3u specifications and are interoperable with other standards-compliant Fast Ethernet products. They have a 115vac 60Hz or 230vac 50Hz external power supply that plugs into a nearby AC wall socket or power strip. The compact packaging, about the size of a bar of soap, does not require rack space and can be conveniently mounted in an office, or out-of-the-way wiring closet area. Metal brackets for optional wall mounting are included.

The Magnum 15E Media Converters and other Magnum products are designed and manufactured in the USA and backed by a three-year warranty.
