Ethernet Cable Fire Ratings

Ethernet Cable Fire Ratings. A cmr rating means the cable can be used in the risers of commercial buildings because they limit the spread of flames better than cables in the cl/cm family. Category 6 cable is a cable standard for gigabit ethernet and other network protocol that is backward compatible with the category 5/5e and category3 cable standard.

Have you ever thought about what was it that connects networks and computers to one another? Network cable in conjunction with the hardware (network hubs, switches, demarcation equipment) is the reason the computers' capability connect and transfer data across intranets (internal networks) and over the internet. Network cabling nowadays is used in many different ways besides computer networking. It is used to transmit video to security camera systems, as well as video for cables for TV as well as AV (Audio/Visual) software. Network cabling can also be used for control cables in Building Maintenance Systems and Access Control Systems. There are a variety of cables that are used for this purpose, such as unshielded the twisted pair, shielded pair fiber optic and coaxial. In certain instances, only one type of cable can be used in a wireless network, or in some cases, many different types are employed. Wireless systems are becoming more and more popular , but keep in mind that you'll need cabling to connect wireless systems. There are two features that make network cabling more effective than wireless networks because it is more safe and reliable.

This is the type of cable that is used in many Ethernet networks. There are four wires within the cable. There is a sturdy plastic separator that keeps each pair separated throughout the stretch of cable. Each pair of wires are twisted so there will be none interference by other equipment within the network. The wires are also twisted in different ways so that they do not cause interference between themselves. If you're in a situation where there's a lot of Electromagnetic Interference (EMI), for instance, a mechanical room, you may choose to utilize a shielded twisted pair that comes with an outer shielding , which offers an extra layer of protection against EMI. Category 5e, 6A, and 7 are the general selections today. Twisted pair cable can be used up to 295' on a horizontal run. Twisted pair cable is utilized in many different applications. The standard station cabling used for computers and VOIP phones wireless access devices, access control, network cameras in building systems, and access control are just several. It is among the most reliable types of cables, and when used, network issues are more rare than those using other cables.

Fiber optic cable is primarily employed as a backbone connection, although it is becoming used more in the form of station cable (think"FIOS). By "backbone" cable, I mean it connects Telecommunication Rooms within the same space to one another. Fiber optic cables are incredibly bandwidth capacities that permit it to transmit large amounts of information as super fast speeds. The fiber optic cable can travel great distances(hundreds of meters) contrary to copper cables. Because they have to work extremely hard and information travels such distances, there are numerous layers of protective coatings on these cables. Fiber cables transmit light as instead of electrical current. Fiber optic cables require less energy than high-speed copper. Cables made of fiber optic is a fantastic choice for high speed reliable communications.

Cable paths should steer away from electrical light fixtures or another source for EMI (Electro Magnetic Interference). Maintain cable paths in a safe zones of the ceiling to allow for future cable runs as well as ease of maintenance. All paths must be located over corridors or hallways, and cables can enter rooms in circular 90-degree angles. Install a firestop sleeve or putty for every entry point into the wall. Be cautious when pulling cables, so as not to bend them beyond their bend radius. This can result in a failure when testing. DO NOT tie cables to ceiling hangers or sprinkler pipes. They must be secured at most every 5' on horizontal runs, and more often on vertical runs. J-hooks should be tied to the concrete deck over. Use velcro wraps on every 5' or so after you have finished running cable to give your cable bundles an appealing look.
