3.5 Calculating Overall Segment Distance
Important Note: Special consideration must be given to maximum cable
segment lengths of a Magnum FT14 and FT14H 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 FT14-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%.
