Magnum14E Media Converters

Installation and User Guide (10/02)

The 100Mb fiber segment must operate in full-duplex (FDX) mode, i.e. a switch (or equal external unit such as a FDX NIC) must be used, and

The worst-case OPB of the fiber link must be greater than the fiber cable’s passive Attenuation.

(Attenuation = Cable loss + LED aging loss + Insertion loss + safety factor)

3.3.2Segment Distances, Full-duplex for copper media (RJ-45) and fiber

Full-duplex ports, such as copper are found in switching hubs and some NICs, can receive and transmit signals simultaneously and do not experience collisions accordingly. There may be only two nodes present on a full-duplex segment. Media distance rules are not the same as for standard (half-duplex) Fast Ethernet because collision distance limitations are not a factor. Specifically, fiber segments can be up to 2Km for multi-mode and up to 25Km for single mode (or 40Km for “Long Reach” single mode).
