Re: PMD Objectives
The rationale for providing the distance granularity in the internet data
the central office was to stimulate debate on the target distances and to
The generic cabling (ISO/IEC 11801 and TIA/EIA-568) topologies and
distances are understood and therefore the granularity was not provided.
1. 300 meters covers the centralized fiber optic cabling distances which
2. A 300 meter solution can be applied to the 100 meter distance.
