Requirements Of Low Voltage Cabling Fremont CA

By Laura Jackson


There are various types of cabling that can be done in a house. Low voltage cabling Fremont CA is the cabling that is done in for internet access, CCTV or TV. It typically involves installing one cable comprising two coaxial cables and two cat 5e, one could also use cat6 instead of the cat5e cables. The cables are bundled together making the installation process faster.

There are three types of cables that can be used. To be able to choose which cable type is best for you. It is important to study the different present cable types. Namely, unshielded twisted pair cables, shielded twisted cables and fiber optic cables.

Each of these cables serve its own purpose. The twisted pair cables as their name suggest are usually twisted together in a bid to minimize cross talk which is a form of attenuation. They are also known as Ethernet cables. These cables are usually cost friendly when compared to any other type of cables and do not have a complex installation process.

Normally, they are terminated using RJ-45 terminations. The weakness of these cables is its proneness to interference from electromagnetic and radio frequency interference and it can also be tapped into hence insecure. It comes in two types, the shielded cables which have an extra coating for shielding and the un shielded cables. The shielded twisted pair cables provide internet connectivity in offices while the unshielded twisted pair cables are most for homes.

Fiber optic cables transmit signals using light pulses unlike the other type of cables that use electrical signals. They have the disadvantage that they are expensive to install and need a higher level of expertise. But they are more secure as it cannot be tapped into and also has a higher bandwidth. In the single cables comprising two coaxial cables and two cat6e cables, two fiber optics cables can be added.

Fiber optic cables are the most expensive of the cable types. They also require the most attention to install. They transmit signals by optical pulses as opposed to other cable types which transmit information through electrical signals. Due to this, they are not affected by electromagnetic or radio frequency and is usually the most secure. It also has a very high bandwidth but is usually the most expensive. Its used to connect to fast internet and also high definition TV.

wire-ring must also be properly done to avoid encountering some problems such as lower performance in terms of bandwidth, that is for internet wire-ring. Also, improper installation leads to attenuation which is loss in signal strength. Some of the ways one could fail in wire-ring is by bending or not terminating in the right way. That is with Ethernet cables, the RJ-45 might be improperly placed.

Low voltage cables is the way to go, first and foremost because it is easy and can be done within a short time. Internet access in homes is made easier. The installation process has also been made faster.
