Commonly called Cat 3, this is an unshielded twisted pair (UTP) cable designed to carry data up to 10 Mbit/s, with a possible bandwidth of 16 MHz. Cat3 was a popular cabling format with computer network administrators in the early 1990s, but fell out of popularity due to the very similar, but higher performing, Cat 5 standard. Now that Cat 5 is becoming obsolete, most new structured cable installations are done using Cat 5e or Cat 6 cable. Cat 3 is still used in two-line telephone systems, although Category 5 or higher would do the same work and allow an easy transition to VOIP at a later date.
CAT 5e Cabling
Category 5 cable, commonly known as Cat 5, includes four twisted pairs in a single cable jacket. It is an unshielded twisted pair cable designed for high signal integrity. In 2001, with the introduction of the TIA/EIA-568-B standard, the CAT 5 cabling specification was made obsolete and superseded by the category 5e specification. It is most commonly used for 100Mbit/s networks, such as 100BASE-TX Ethernet, although IEEE 802.3ab defined standards for 1000BASE-T - gigabit Ethernet over category 5 cable.
CAT 6 Cabling
Cat 6- Category - 6, (ANSI/TIA/EIA-568-B.2-1) The CAT6 cable contains four twisted copper wire pairs and is a cable standard for Gigabit Ethernet and other network protocols that is backward compatible with both the Category 5/5e and the Category 3 cable standards. The CAT6 cable standard is suitable for 10BASE-T / 100BASE-TX and 1000BASE-T (Gigabit Ethernet) connections, and it provides outstanding performance of up to 250 MHz. When used as a patch cable, Cat6 is normally terminated in an RJ-45 connector. As with all cables defined by TIA/EIA-568-B, the maximum allowed length of a Cat6 cable run is 90 meters. A complete channel (includes horizontal cable plus cords on either end) is permitted to be up to 100 meters in length, depending upon the ratio of cord length/horizontal cable length.
Cat7 Cabling
Category 7 cable (CAT7), This cable contains four twisted copper wire pairs just as the earlier standards, and is a cabling standard for Ethernet and other similar interconnect technologies that can be backwards compatible with traditional CAT5 and CAT6 Ethernet cable. CAT7 features several even more stringent specifications for system noise and crosstalk than CAT6. To achieve this level of performance, shielding has been added for individual wire pairs and the cable as a whole. (ISO/IEC 11801:2002 category 7/class F)
The CAT7 cabling standard has been created to allow up to 10-gigabit Ethernet over 100 meters of copper cable. CAT7 can be terminated either with RJ-45 compatible GG45 electrical connectors that incorporate the RJ-45 standard or with special TERA connectors. When combined with GG-45 connectors, CAT7 cable is then rated for transmission frequencies of up to 600 MHz. If combined with TERA connectors, CAT7 cable is rated for transmission frequencies above 600 MHz.
Fiber Optic Cabling
Fiber Optic cabling provides a far greater bandwidth than standare copper and is commonly used for backbone connection between local networking equipment. It is increasingly becoming the preferred choice for both top quality and highly reliable analog and digital communications. Although the higher cost can be prohibitive for standard desktop applications, fiber optic cabling provides a high security link with immunity from EMI (electromagnetic interference). It is now also the standard solution for inter-building links, inter-network links, and other connections that extend beyond the maximum 90 meters for Category 5e copper cabling.
All types of fiber optic cabling systems are offered, and all cables are internal and externally graded.
Coax Cabling
Coaxial cable is an electrical cable commonly used in video and high speed broadband applications. Coaxial cable consists of a round conducting wire, an insulating spacer, surrounded by a cylindrically shaped conducting sheath, and is usually surrounded by a final insulating layer. It is used as a high-frequency transmission line to carry high-frequency video applications or broadband signals.
Additional Cabling
In addition to the above cabling projects, we also offer wireless infrastructure cabling, server room cabling, voice cabling, data cabling, video cabling, surveillance camera cabling, phone system cabling, and data network cabling.
