Twisted-Pair (Balanced) Cabling
The categories of transmission performance specified by Siemon for cables, connecting hardware links and channels are:
 |
Transmission characteristics are specified up to 16 MHz. | Meets applicable category 3 and class C requirements of ISO/IEC 11801:2002, ANSI/TIA/EIA-568-B.1 & B.2. Requirements are specified to an upper frequency limit of 16 MHz. |
 |
Transmission characteristics are specified up to 100 MHz. | Performs to category 5e of '568-B.1 & B.2 and additional class D requirements of ISO/IEC 11801:2002. Requirements are specified to an upper frequency limit of 100 MHz. |
 |
Transmission characteristics are specified up to 250 MHz. | Performs to category 6 of '568-B.2-1 TIA-TSB-155 draft, and class E requirements of ISO/IEC 11801:2002. Requirements are specified to an upper frequency limit of 250 MHz. This classification is a superset of Category 5e. |
 |
Transmission characteristics are specified up to 500 MHz. | Performs to category 6 of '568-B.2-1 and '568-B.2-10 and class E of ISO/IEC 11801:2002 and amendment NBS 1 to ISO/IEC 11801. Requirements are specified to an upper frequency limit of 500 MHz. This classification is specified with the additional requirements of TSB-155 to support the operation of 10GBASE-T over 4-connector channel to typologies over distances from at least 55m up to 100m. |
 |
Transmission characteristics are specified up to 1.0 GHz. | Performs to category 7 and class F requirements of ISO/IEC 11801:2002. Requirements are specified to an upper frequency limit of 600 MHz. This classification is an electrical superset of Category 6. Supports all parameters to 1.0 GHz for compliance to ISO/IEC 15018 and ISO/IEC 11801 Ed. 2, Amd. 1st draft. |
- Note:
- Augmented category 6 draft requirements are still in development and are intended to be published before 2006.
Terminology and classifications specified in ISO/IEC 11801:2002 for cabling links differ slightly from TIA categories. Components and installation practices are subject to all applicable building and safety codes that may be in effect.
