Technical Manager



UTP vs. FTP

• Two copper solutions for 10Gb/s – UTP and FTP

• Effects of Alien Crosstalk (ANEXT)

• ANEXT Mitigation Methods

• Standards Approach

Data Rates

• Standard written around 10Gb/s• Category 6A Added to Standard

• Backwards Compatible with Cat6 and Cat5e

• Category 5e removed from standard

• IEEE 802.11an Standard

• 10Gb/s over installed base of Category 6 – May Require Mitigation

Performance of Channel vs.

Components

• Be careful of Cable test measurements that exceedthe TIA568.B.2 - 250 MHz frequency sweep

– 600 MHz frequency is not achievable in a field channel

• When comparing performance specif ications it isimportant to view the entire channel

• Ensure manufacturer is warranting the entire channelnot just the components they manufacture

FIELD TESTING

• Field Testing is NOT specified in theStandards for UTP or FTP – it is an

option.

• Most UTP manufacturers do not require

ANEXT testing to warranty system

• To ensure meeting quality metrics both

UTP and FTP should be tested.

• FTP Shield continuity testing

Shared Cable Pathways

• TIA-568-B.2-10 E.4 Test Configurations“ Alien Cross-talk requirements for category 6Achannels and permanent links are specif ied for bundled configurations containing only category

6A cabling requirements”• Manufacturers publish specific installation

guidelines for various situations



• Separation of Cat6A UTP cabling from lower categories is an issueif the lower categories are supporting 10G. For all other applicationsthere is no issue.

• Typical Cabling Requirements

• Cable types are laid, routed, and/or bundled in separate groups

• Pull each cable type separately• Cables can be layered but not intermingled• If alternate pulling of each cable type is planned, then side by side

posit ions in the tray must be allocated for each cable type
