What is a structured cabling system?
A structured cabling system (SCS) is a set of cabling and connectivity products that integrates the voice, data, video, and various management systems of a building (such as safety alarms, security access, energy systems, automation, etc.).

Networking Components for Structured Cabling
Our LAN support solutions make office environments expandable, manageable, and organized. They comprise all the network components you'll need, from the work area to the cross-connect in the telecommunications closet. Our total systems eliminate the risk of lurking weak points that can affect your network's critical performance.


UTP Patch Cables/Line Cords -  Unshielded Twisted Pair (UTP) Patch Cables and Line Cords are used to connect two nearby components, such as a PC to a wall outlet, or a patch panel to a hub. We offer these Cables and Cords in a wide variety of colors and styles.
Fiber Optic Patch Cables - Used to connect two nearby components with fiber connectors, these Cables transmit data with light, so you don't have to worry about electrical interference.
UTP Horizontal Cables - These Cables are made from solid-conductor wires and typically used for in-wall premise installation. We provide high-quality Category 5e and Category 6 horizontal cables.

RJ45 Plugs - RJ45 Plugs are used to make UTP Patch Cables. We carry Plugs with both flat and round entrances, for making flat cables and rounded UTP cables.
Jacks -  We offer a vast selection of jacks, so you can complete and customize your networking outlets.
Outlets and Faceplates -  Our outlets provide the perfect combination of insert and faceplate features. They are the hardware you need to interface patch and horizontal cables.
Inserts -  We carry a full array of inserts for all your networking needs. They snap easily into a faceplate, to make your workspace network-ready.
Patch Panels -  We carry a variety of patch panels, featuring from 12 to 96 ports. We provide everything you need to set up a manual switching center for incoming and outgoing telecommunication and electronic lines.

Racks & Cabinets -  We offer a wide range of racks and enclosures to store, secure, and organize your data and voice equipment. They help ensure that your devices run effectively and efficiently.
Cable Management -  We provide various types of cable management. From a 19-inch rack-mountable panel for racks and cabinets, to simple cable ties, we have the best ways to keep your network organized and your cables optimally arranged.
Raceways - This on-the-wall tracking protects and conceals networking cables without requiring you to run cables behind the wall.   
Token Ring, Legacy Systems - Systems developed before TIA/EIA 568A standards, such as the token-ring network, are still in use today. We carry everything needed to maintain legacy systems. 


Cat- 3
The standard interface for phone system connections and analog data connection such as modems and fax machines.

The CAT5e standard allows for transmission speeds of up to 1000mbps (giga-bit Ethernet). There is little real difference in the cabling standards between CAT5 and CAT5E, the standards for CAT5E being only a little more stringent over CAT5. CAT6 gives a more stringent standard for 1000mbps Ethernet network cabling. 

Cat-6, is a cable standard for Gigabit Ethernet and other network protocols that is backward compatible with the Category 5/5e and Category 3 cable standards. Cat-6 features more stringent specifications for crosstalk and system noise. The cable standard provides performance of up to 250 MHz and is suitable for 10BASE-T / 100BASE-TX and 1000BASE-T (Gigabit Ethernet). It is expected to suit the 10GBASE-T (10Gigabit Ethernet) standard, although with limitations on length if unshielded Cat 6 cable is used. Category 6 cable can be identified by the printing on the side of the cable sheath. The cable contains four twisted copper wire pairs, just like earlier copper cable standards. Although Cat-6 is sometimes made with 23 gauge wire, this is not a requirement; the ANSI/TIA-568-B.2-1 specification states the cable may be made with 22 to 24 AWG gauge wire, so long as the cable meets the specified testing standards. When used as a patch cable, Cat-6 is normally terminated in 8P8C modular connectors, often incorrectly referred to as "RJ-45" electrical connectors. Cat-6 connectors are made to higher standards that help reduce noise caused by crosstalk and system noise. Attenuation, NEXT (Near End Crosstalk), and PSNEXT (Power Sum NEXT) are all significantly lower when compared to Cat-5/5e.

 (CAT7), (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 CAT5 and CAT6 Ethernet cable. CAT7 features even more strict specifications for crosstalk and system noise than CAT6. To achieve this, shielding has been added for individual wire pairs and the cable as a whole. The CAT7 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 Cat6A). The cable contains four twisted copper wire pairs, just like the earlier standards. CAT7 can be terminated either with RJ-45 compatible GG45 electrical connectors which incorporate the RJ-45 standard or with TERA connectors. When combined with GG-45 or TERA connectors, CAT7 cable is rated for transmission frequencies of up to 600 MHz.

 Optical Fiber
Fiber optics are typically employed when data transmission speed requirements are extremely high, or distance of greater than 3,000 feet are required between network connections.

Type of wire that consists of a center wire surrounded by insulation and then a grounded shield of braided wire. The shield minimizes electrical and radio frequency interference.
Coaxial cabling is the primary type of cabling used by the, cable television video service and video surveillance.

Unshielded Twisted Pair
This flexible, low cost media can be used for either voice or data communications. Its greatest disadvantage is the limited bandwidth, which restricts long distance transmission with low error rates. A Twisted Pair is a pair of copper wires, with diameters of 0.4-0.8 mm, twisted together and wrapped with a plastic coating. The twisting increases the electrical noise immunity, and reduces the bit error rate (BER) of the data transmission. A UTP cable contains from 2 to 4200 twisted pairs

Pratt Communications can provide full network cabling, including hubs, routers, switches, jacks, and patch cables.
