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 and 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 subsytems 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.
