B Twisted-Pair Cable and Pin Assignments

Note that when testing your cable installation, be sure to include all patch cables between switches and end devices.

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 International Telecommunication Union (ITU-T) has standardized various fiber types for data networks. These are summarized in the following table.

TABLE 8	FIBER STANDARDS

ITU-T Standard	Description	Application

G.651	Multimode Fiber	Short-reach connections in the 1300-nm or
	50/125-micron core	850-nm band.

G.652	Non-Dispersion-Shifted	Longer spans and extended reach.
	FiberSingle-mode, 9/125-micron core	Optimized for operation in the 1310-nm
		band. but can also be used in the 1550-nm
		band.

G.652.C	Low Water Peak
	Non-Dispersion-Shifted Fiber
	Single-mode, 9/125-micron core

Longer spans and extended reach.

Optimized for wavelength-division multiplexing (WDM) transmission across wavelengths from 1285 to 1625 nm. The zero dispersion wavelength is in the 1310-nm region.

G.653	Dispersion-Shifted Fiber	Longer spans and extended reach.
	Single-mode, 9/125-micron core	Optimized for operation in the region
		from 1500 to 1600-nm.

G..654	1550-nm Loss-Minimized	Extended long-haul applications.
	FiberSingle-mode, 9/125-micron core	Optimized for high-power transmission in
		the 1500 to 1600-nm region, with low loss
		in the 1550-nm band.

G.655	Non-Zero Dispersion-Shifted	Extended long-haul applications.
	FiberSingle-mode, 9/125-micron core	Optimized for high-power dense
		wavelength-division multiplexing (DWDM)
		operation in the region from 1500 to
		1600-nm.
