3.5 Calculating Overall Segment Distance
Important Note: Special consideration must be given to maximum cable
segment lengths on each side of a Magnum TF14 and TB14 Media Converter. It is
recommended that IEEE 802.3 specifications for overall maximum segment distances be
adhered to in order to maintain optimum network performance. (See also Technical
Specs, Maximum Standard Ethernet Segment Distances, Section 1.1 of this manual.)
When installing the Magnum 14-series Media Converter, it is important to
consider the combined overall segment length of both of the attached media types. The
overall segment length is calculated by adding together the segment lengths on both sides
of the Magnum Media Converters. Cable segment length on each side of the Media
Converter is measured as a percentage of the maximum allowable standard media
distance for the given media type. The percentages, when added together, must not
exceed 100%.
Media Distance Formula for Magnum Media Converters:
X% + Y% < 100%
Where X = The segment distance on one side of the Magnum Media Converter
divided by the Standard Maximum Media Distance for that media type, x 100%.
