9 The Move to Cat 5e June 1996 - IEEE 802.3 begins work on Gigabit Ethernet Questions raised about unspecified parameters of Category 5 Also need to standardize manufacturers claims of performance in excess of Cat 5

Addendum 1 1 0 September 1997 - TIA/EIA-568-A-1: Propagation delay and skew requirements added for Cat 5 cable.

1 3 Addendum vs. TSB The TIA changed its position on SP-4194 Can t place new specifications on existing components and installations Information has been published as TSB 95 Informational purposes Changes from shall to probably!

TSB95 - Additional Cat 5 Specifications 1 4 The development of certain high-speed applications has brought to the attention of the TIA the need for additional transmission requirements such as return loss and far end crosstalk (FEXT). These parameters are needed by system designers for applications that utilize all four pairs in the cable for full duplex transmission. Although these are new specifications, the existing worst-case, two-connector topologies compliant with TIA/EIA-568-A are expected to meet these requirements. Other topologies are supported as long as they meet the ELFEXT and Return Loss requirements of this document.

SP-4195 - Enhanced Cat 5 1 9 The development of certain high-speed applications has brought to the attention of the TIA the need for additional transmission requirements such as multi-disturber NEXT, return loss and multi-disturber far end crosstalk (FEXT). These parameters are needed by system designers for applications that utilize all four pairs in the cable for simultaneous bi-directional transmission. Addendum 5 for category 5e cabling provides higher performance over a minimally compliant category 5 channel and recognizes advances in cabling technology.

What Do You NEED to Run 1000BASE-T? 2 2 IEEE 802.3ab Physical layer specification for 1000 Mb/s operation on four pairs of Category 5 or better balanced twisted pair cable (1000BASE-T) 40.8 Link Segment Characteristics 1000BASE-T uses a duplex transmission system. Four full duplex channels are required to transport data between two PMDs. Each duplex channel supports an effective data rate of 250 Mbps in each direction simultaneously. The term link segment used in this clause refers to four duplex channels and the term duplex channel will be used to refer a single channel with full duplex capability. Specifications for a link segment applies equally to each for the four duplex channels. 1000BASE-T is designed to operate over a 4-pair Category 5 cabling system.

Designed to Operate Over Cat 5, BUT... 2 3 ANNEX 40A Additional Cabling Design Guidelines Although the 1 Gb/s specification described in Clause 40 was designed to operate over 4- pair Category 5 cabling systems as specified in ANSI/TIA/EIA-568-A and ISO/IEC 11801, there are additional steps that may be taken by network designers that will provide additional operating margins and ensure the objective BER of 10-10 is achieved. Power Sum NEXT Defined but not spec d higher than Cat 5 Power Sum ELFEXT Spec d in TSB95 (Cat 5) Don t use 25-pair Don t use crossconnect or transition point

2 4 Cat 5 and Cat 5e Bottom Line Cat 5 will probably run Gigabit Ethernet. But maybe only with two connectors! Cat 5e provides the extra margin required to ensure 1000BASE-T support with 4-connector channels. It s been ratified as TIA/EIA-568-A-5. Cat 5 is not recommended in TIA/EIA-568-B. It s been relegated to an annex. Cat 5e is the minimum recommendation for data cabling.

2 5 What About Category 6? Cat 6 was originally a German DIN standard addressing shielded cabling systems with performance out to 600 MHz. Category 6/Class E was re-proposed by ISO/IEC 11801-A as specifying positive channel performance to 250 MHz. Both the ISO and the TIA are now working on Cat 6 and its frequency range has been extended to 250 MHz. The German DIN Cat 6 is now Cat 7/Class F, also under development by the ISO.

Category 6 Patch Panels 3 5 Use identical circuitry for each port to ensure consistent performance Many panels use different circuitry for each port. This means that the performance is different for each port.

3 6 Category 6 Patch Cable Assemblies Designed to provide optimum performance when combined with AMP NETCONNECT Cat 6 jacks, panels and cable Flexible, robust stranded cable Color matched snagless boots ½ Ft. to 50 ft. lengths

The Channel 3 7 The most important performance characteristics are those of the channel. The channel numbers represent the performance of the entire cabling system.

3 8 Channel Performance In order to be Cat 6 compliant, the entire cabling system must meet all of the requirements when configured in the worst-case configuration. The worst-case configuration allowed by the TIA is the 100-meter, 4-connector channel. On March 5, 2001 Intertek Testing Services tested AMP NETCONNECT plenum and non-plenum channels constructed from production Category 6 products. The following slides show the absolute worst performance at each frequency point from those tests.

4 3 Why a System Approach? Piecemealing cabling infrastructure components is no longer a viable approach to delivering reliable, high performance networks The entire system must be evaluated as a whole to ensure the best performance The AMP NETCONNECT Category 6 System has been independently tested to confirm 250 MHz bandwidth performance Customers attempting to assemble cabling systems through so-called best of breed components are not guaranteed the best system performance levels

Category 6 System Benefits 4 4 Designed, engineered and manufactured as a System It s not enough to have good components Installed as a System NETCONNECT Design and Installers (ND&Is) Rigorous and demanding training and qualification Tested and certified as a System Leading-edge, state-of-the art Demanding test procedures are required Warranted as a System From Tyco to the end-user The Total System from One Source
