Adjusting Existing Category 5 Cabling to Run 1000BASE-T
If your existing Category 5 installation does not meet one of the test
parameters for 1000BASE-T, there are basically three measures that can be
applied to try to correct the problem:
1. Replace any Category 5 patch cables with high-performance Category 5e
or Category 6 cables.
2. Reduce the number of connectors used in the link.
3. Reconnect some of the connectors in the link.

Fiber Standards

The current TIA (Telecommunications Industry Association) 568-A
specification on optical fiber cabling consists of one recognized cable type
for horizontal subsystems and two cable types for backbone subsystems.
Horizontal 62.5/125 micron multimode (two fibers per outlet).
Backbone 62.5/125 micron multimode or single-mode.
TIA 568-B will allow the use of 50/125 micron multimode optical fiber in
both the horizontal and backbone in addition to the types listed above. All
optical fiber components and installation practices must meet applicable
building and safety codes.
