CAT 7 Standards- SIEMON CAT7 Specifications- TIA CAT7 Standards

Category 7 cable (Cat 7), (ISO/IEC 11801:2002 category 7/class F), is a cable standard for Ethernet and other interconnect technologies that can be made to be backwards compatible with traditional Cat 5 and Cat 6 Ethernet cable. Cat 7 features even more strict specifications for crosstalk and system noise than Cat 6. To achieve this, shielding has been added for individual wire pairs and the cable as a whole. Category 7 is recognized for all the country organizations members of ISO.

The Cat 7 cable standard has been created to allow 10 Gigabit Ethernet over 100 m of copper cabling (also, 10-Gbit/s Ethernet now is typically run on Cat 6a). The cable contains four twisted copper wire pairs, just like the earlier standards. Cat 7 can be terminated either with 8P8C compatible GG45 electrical connectors which incorporate the 8P8C standard or with TERA connectors. When combined with GG45 or TERA connectors, Cat 7 cable is rated for transmission frequencies of up to 600 MHz.

[edit] Category 7a

Category 7a (or Augmented Category 7) is defined at frequencies up to 1000 MHz, suitable for multiple applications in a single cable (just like all other categories) including CATV (862 MHz).^[1][2][3] Simulation results have shown that 40 Gigabit Ethernet is possible at 50 meters and 100 Gigabit Ethernet is possible at 15 meters.^[1] Mohsen Kavehrad and researchers at The Pennsylvania State University believe that either 32 nm or 22 nm circuits will allow for 100 Gigabit Ethernet at 100 meters.^[4][5]

However, similar studies in the past have shown that Cat5e could support 10 Gbps, so these should be read with caution. Furthermore, as of June 2010, the IEEE is currently not looking into 40 Gbps or 100 Gbps for Cat7a in its draft 802.3ba. It may in the future, but there is absolutely no guarantee that such applications will ever exist.

Cat7a is currently in ISO standards for channel performance in Amendment 1, recently component performance has been ratified in Amendment 2. The formal names are ISO 11801 Amendment 1(2008) and ISO 11801 Amendment 2 (2010).

Class F

Class F requirements were published in 2002 and describe performance criteria for a fully shielded media type (i.e. cabling with an overall shield and individually shielded pairs). Category F cabling delivers positive attenuation-to-crosstalk margin up to 600 MHz and offers unsurpassed electromagnetic capability (EMC) performance because of its shielded construction.

Due to its ease of use, performance headroom, ability to support multiple applications under one sheath, and its specification as the recommended category 7 interface in the ISO 15018 Standard, the non-RJ style plug and socket interface specified in IEC 61076-3-104:2002 is the most commonly specified category 7 connector. This interface is commercially available from multiple manufacturers whose products are interoperable. There is significant evidence that the cabling industry and applications developers are ready to adopt fullyshielded cabling. For example, class F cabling was identified as the copper media of choice in one IEEE new application call-for-interest and the published ISO/IEC 14165-114 application Standard, entitled, "A Full Duplex Ethernet Physical Layer Specification for 1000 Mbit/s operating over balanced channels Class F (Category 7 twisted pair cabling)", specifies operation over a minimally rated class F channel.

It is interesting to note that, although TIA is not actively developing a standard for category 7 at this time, it is acceptable to specify class F cabling in North American and other markets. The rationale for this is that, in addition to being recognized by BICSI, NEMA, IEEE, and other standards organizations, class F is simply a superset of TIA category 6A requirements. Field test requirements and adapters for class F cabling qualification have been commercially available since 2002.

The advantage that class F has over other grades of cabling is that it is targeted for support of next generation applications beyond 10GBASE-T. Class F cabling is the only media to have a 15-year lifecycle and class F cabling provides the maximum return-on-investment when calculations are performed using a 15-year lifecycle.

Class F_A

Class F_A requirements are based upon the existing class F cabling requirements and category 7 non-RJ style plug and socket interface. The significant enhancement in class F_A specifications is the extension of the frequency bandwidth of characterization from 600 MHz to 1,000 MHz. This enhancement allows class F_A cabling to be uniquely capable of supporting all channels of broadband video (e.g. CATV) that operate up to 862 MHz. It is likely that all fully-shielded cabling solutions specified in the near future will be class F_A.

Conclusion:

When designing and installing structured cabling systems, choose the strongest foundation to support your present and future network applications needs. To ensure support of emerging technologies that utilize the latest advances in signaling schemes, it is critical to be as informed as possible. Trust the TIA and ISO standards developmental groups to specify complete cabling criteria capable of providing applications assurance for tomorrow's technologies today.

TERA®-MAX® Adapters for CT Faceplates	Siemon offers multiple CT adapter options for TERA and UTP MAX outlets to extend use of CT faceplates and other CT accessories beyond the use of CT couplers. Siemon`s new angled CT adapter allows TERA and MAX outlets to be mounted in CT faceplates and other accessories with CT openings. The adapter provides an angled work area mounting solution while using flat outlets, particularly useful in TERA applications. By orienting the outlets at an angle, it also reduces the mounting depth requirements to overcome shallow back boxes and other application challenges. Siemon`s new horizontal angled CT adapter allows TERA and MAX outlets to be mounted in CT faceplates and other accessories with CT openings. By orienting the outlets at an angle, this adapter reduces the mounting depth requirements to overcome shallow back boxes and other application challenges.

TERA® Patch Cords	Part of the TERA cabling solution, TERA-to-TERA patch cords deliver twice the bandwidth of category 7A/class FA specifications when combined with the TERA outlet. TERA delivers up to 1.2 GHz of bandwidth per pair, providing the extra bandwidth critical for demanding applications like Broadband Video, with an upper frequency requirement of 862 MHz. Facilitated by 1- and 2-pair patch cords, TERA’s extended performance also supports cable sharing — the simultaneous convergence of video, voice and data onto a single 4-pair cable and outlet. 4-pair TERA-to-TERA supports category 7A/class FA performance to 10Gb/s and beyond Standard compliant interface — recognized within ISO/IEC 11801 Ed. 2.0 2-pair TERA-to-screened category 5e MC modular plug for 10/100 Ethernet, VoIP and video over IP 4-pair TERA-to-screened augmented category 6A MC modular plug for 1G/10G Ethernet performance 1-pair TERA-to-TERA for analog voice and video patching.

TERA® 4-Pair Outlet	TERA outlets are the industry’s highest performing network cabling connectors. Outlets accept 1-, 2- and 4-pair plugs and terminate fully shielded category 7/class F cables. TERA outlets can be used in both the work area and in the telecommunications room.
TERA® Cable Preparation Tool	The TERA cable preparation tool uses a patent pending process to significantly reduce the time required to prepare fully shielded (S/FTP) cable. The tool includes an insert die with a blade, which is specifically designed to accurately strip the jacket and foil from 4-pair fully shielded cable without damaging the conductors. A template is also included to pre-align cable pairs and ensure proper pair positioning during termination.
TERA® Video Patch Cord	TERA CATV baluns provide the optimum solution for the transmission of TV or CATV signals over structured cabling systems that were historically limited to voice and data transmission. These products convert the unbalanced TV signals designed for coaxial cabling (75 Ohm impedance) to balanced signals (100 Ohm impedance) as required for transmission over twisted pair (balanced) cabling. The TERA CATV adapters are specified and useable to 862 MHz. The 1-pair TERA to PAL and TERA to F-Type patch cords utilize an integrated balun. The 1-pair shielded TERA to shielded RJ45 patch cord allows connection to third-party RJ45 baluns. One cord used on each end of the video channel Minimizes cabling material and labor costs by consolidating applications on a single cable Only occupies a single pair in a TERA system to allow cable sharing Enables video transmission over structured cabling PAL or F-Type connector (IEC 60169-24) with integrated balun to interface with common video equipment
