![]() We’ll be sharing information about how Category 8 compares to its predecessor versions. Stay tuned for more information about Category 8 cabling on our blog in January. The timeframe to publish the IEEE 25GBASE-T/40GBASE-T standards is also 2016. It is under development in the TIA TR42.7 Subcommittee, and will be published as TIA-568-C.2-1 by mid-2016. When will the Category 8 standard be ratified? Low power is one of the key objectives of the IEEE 802.3bq taskforce developing the 25GBASE-T/40GBASE-T standard. The power needed to transmit a signal 30 meters at 40 Gb/s is approximately the same as the power needed for 10GBASE-T transmission for distances up to 100 meters. No, because 25GBASE-T/40GBASE-T equipment is designed to operate over shorter distances up to a maximum of 30 meters. Will Category 8 cables require more power? Backward compatibility with RJ45 is not assured, and would most likely require a hybrid patch cord. Various connectors may be used for a Class II system it is not clear whether a choice will be made to select a single connector. It’s based on the Category 7A system specified in ISO 11801 2nd edition. There is also an ISO Category 8.2 (Class II system) under development. 2 Port Serial-to-IP Ethernet Device Server - RS232 - Metal and Mountable - Serial Device Server - RS232 Serial-Over-IP (NETRS2322P) (NETRS2322P) Model : NETRS2322P-0. ![]() To compare, Category 6A is specified to 500 MHz. The transmission performance of a Category 8 mated plug-jack connection is specified and performs well up to a frequency of 2 GHz. Will we need new connector types for Category 8?Ĭategory 8 connectors use the 8-pin modular (RJ45) connector, and are fully backward compatible with previous categories. Today it is intended primarily for 25G and 40G applications for short distances (up to 30 meters) for switch-to-server connections in a data center. The maximum reach for 25GBASE-T/40GBASE-T is 30 meters, which will be sufficient for most switch-to-server connections for top-of-rack (ToR), middle-of-row (MoR) or end-of-row (EoR) topologies. Meeting these requirements requires a shielded cabling system (F/UTP, S/FTP or F/FTP). Port-based, 802.What are the main characteristics of Category 8? How will it affect data center infrastructure?Ĭategory 8 cabling and components are specified with transmission performance of up to 2 GHz (four times the bandwidth of Category 6A cabling) with more stringent alien crosstalk requirements.
