What about My Installed Category 6 Cabling Plant?
The good news for category 6-compliant cabling plant owners is that a large percentage of the installed base is anticipated to be able to support the 10GBASE-T application. Based upon IEEE objectives, 10GBASE-T is designed to operate over at least 55 meters of category 6 cabling within a "reasonable" worst-case alien crosstalk environment. Furthermore, data presented by IEEE members during the 10GBASE-T objectives development phase illustrated that approximately 68% of today's installations fall below this minimum length requirement.
Look to the guidance specified in the pending TIA TSB-155 document for a comprehensive overview of the minimum transmission performance (including alien crosstalk and extended frequency characterization) required to support the 10GBASE-T application over reduced lengths of category 6 cabling. The final channel length to be specified in TSB-155 is, at the time of writing, undetermined.
Requirements for the level IIIe compliant field testers needed to verify the performance of the installed based and their associated test and sampling methods are provided. Since field evaluations have indicated that bundling practices may have resulted in excess alien crosstalk in some category 6 installations, TSB-155 also lists mitigation techniques that may be employed to improve alien crosstalk performance.5
The cabling industry universally recommends that it is not good practice to design new cabling plants to support 10GBASE-T with reduced-length category 6 cabling. Return-on-investment (ROI) modeling demonstrates that the additional testing and downtime costs to ensure that a category 6 cabling plant can support 10GBASE-T for distances up to 55 quickly surpasses the cost differential between category 6 and augmented category 6A media at installation time (see figure below).
