A business is using the local cable company to provide Internet access. Which of the following types of cabling will the cable company MOST likely use from the demarcation point back to the central office?
C. RG-6 is the type of cabling that the cable company is most likely to use from the demarcation point back to the central office.
RG-6 (Radio Guide 6) is a type of coaxial cable that is commonly used for cable TV and broadband Internet service. It is capable of carrying high-frequency signals over long distances and it has a thicker insulation and shielding than other types of coaxial cable. This makes it less susceptible to interference from other sources and better able to maintain signal quality over long distances. Multimode is used for short distance communications and it's not suitable for long distance, Cat 5e and cat 6 is used for Ethernet networks. 100BASE-T is a type of Ethernet standard that uses twisted-pair cables and is typically used for short-distance communication.
RG-6 cable is only used from Demarc to the pole or node. The main line back to the central office would be either 750 cable or fiber. Multimode fiber will allow transmission distances of up to about 10 miles. So, C. RG-6 cable is right for short distances it loose about 5db per 100 feet. So, it cannot get back to the central office.
Most cable companies use hybrid fiber-coax on their plants. Fiber extends out of the CO to the Nodes then convert over to coax from the node to the Demarc. So really there is no right answer. But C is the closes. I worked for cable for 28 years.
Most cable companies use hybrid fiber-coax on their plants. Fiber extends out of the CO to the Nodes then convert over to coax from the node to the demarc.
The cable company will most likely use RG-6 cabling from the demarcation point back to the central office. RG-6 is a type of coaxial cable that is commonly used for cable television and Internet service provider (ISP) installations. It is designed to carry high-frequency signals and has lower signal loss and higher bandwidth capabilities than twisted pair cabling such as Cat 5e or Cat 6. Multimode and 100BASE-T are not types of cabling, but rather refer to different networking standards.
Most cable companies uses HFC network (hybrid fiber-coaxial). Technically, the signal starts at the central office using fiber and it branch out through a combination of Nodes and extenders. RG-6 is only from the service terminal to the home.
