Coaxial cable is designed to shield the communications medium from EMI and maintain the integrity of wire transmissions. There are specific distances that various types of coaxial cable can travel without repeaters or bridge filters. The most typical distance for ethernet is about 100meters. High-Speed (DSL) cables can go up to a mile before performance suffers. There are several types of cable in use to support various transmissions. The older STP, Thinnet/RG-58 cable used for ethernet has been replaced by Category-5 cable. Radio feed-lines use RJ-58, LMR-400 or even hard-line "wave guide" between transmitter and radiator (antenna). Cable Television is really the only mass-broadcast medium that still uses cable. It's important to remember that the coaxial connections are as critical as the coax quality it self. An exposed ground-shield on one end of a cable can both radiate unauthorized emissions, as well as be subject to interference from external EMF sources.
What else can I help you with?
What cables carry the signal from a cable modem to a PC is it a RCA cable HDMI ethernet or coaxial?
coaxial
Does coaxial cable carry a current?
Yes, this is how the data is transmitted.
Why does my Dell Inspiron 4000 have a coaxial cable in it?
The Dell Inspiron 4000 does not include a coaxial jack. Unless you are using a third-party add-on, you are most likely confusing the S-Video jack / cable with coaxial. S-Video is used for outputting high-quality video to newer televisions. It does not, unlike coaxial cable, carry an RF signal.
Is the HDMI cable coaxial?
No. HDMI cable uses a 19-pin connector for twisted pair connections that carry video, audio and control in digital format.
What does 'coaxial cable' mean?
The term coaxial comes from the inner conductor and the outer shield sharing ("co-") the same axis. It is often used as a high-frequency transmission line to carry a high-frequency or broadband signal but may also be used for frequencies as low as audio frequency.
Can you use coax cable for digital?
Yes. Coaxial cable is the preferred method for carrying the signal. The important factor is the frequency of the signal that is being carried by the cable. Most coaxial cable that you will want for carrying your signal will be RG-6. This will handle signals for radio, television, and satellite receivers. It is not important whether it is an analog or digital program. Some manufacturers use a deceptive advertising technique and will emphasize that their cable is for digital signals. They want you to think that another competing product that does not make a claim to be for a digital signal is not suited for digital. The cable doesn't know the difference between a digital or an analog radio frequency signal. It handles both of them in exactly the same manner. Some important specifications to consider when selecting a coaxial cable are: -Bandwidth (what frequencies can it carry) -Attenuation (how well does it carry the signal without weakening it) -Impedance (proper impedance matching helps to carry the signal - most cable will be 75 ohm and will need to be used for 75 ohm equipment, 50 ohm cable for 50 ohm equipment) Don't use a long cable when a short one will do. A longer cable attenuates (weakens) the signal more. RG-59 can be used for short distances, but RG-6 is a much better choice. RG-59 is not a good choice for HDTV or satellite signals, but it can be used for connecting a VCR to a television.
What cable is the type used by the cable television industry?
The cable television industry predominantly uses coaxial cable for signal transmission. Coaxial cable is designed to carry high-frequency signals, featuring a central conductor surrounded by insulation, a metallic shield, and an outer insulating layer. This construction helps minimize interference and allows for high bandwidth, making it ideal for delivering television content effectively. Additionally, fiber optic cables are increasingly being used for higher capacity and faster data transmission in modern cable systems.
What is the major factor that makes coaxial cable less susceptible to noise than twisted-pair cable?
A coaxial cable is shielded from electrical interference signals whereas UTP (Unshielded Twisted Pair) cable is not. The random twisting with which UTP is manufactured works very well, however, in locations where the interference levels are relatively low, because its method of construction ensures that any interference affects both wires in the pair equally. It should also be mentioned that STP (Shielded Twisted pair) cable is also available and is sometimes specified for LANs (Local Area Networks) instead of coaxial cable. But the much greater volume of coaxial cable sold means that coaxial cable prices have been kept very competitive with STP. As STP tends to be more tricky to install - its shield has to be very carefully and correctly terminated at each end - coaxial tends to be used more than STP where noisier-than-normal interference conditions are present at a particular site. Since the 1990s NIC (Network Interface Card or Component) equipment has had extra logic cicuits within it to reject ambient interference much more effectively than equipment which was designed in the previous 20 years, so nowadays UTP can be used more extensively in locations where only STP or coaxial cable would have had to be used before. So, in relation to LANs in normal non-industrial office and domestic buildings, this exam question is now almost obsolete! However coaxial cable is still necessary to carry LANs in difficult environments such industrial plants; hospitals; undergound railway and road tunnels and mines; on board ships and aircraft, etc. and must also be used to carry signals for radio, televison, video and other applications which run at much high frequencies and bandwidths than LANs.
Can you connect a high definition tv to regular digital cable?
Co-ax cable is quite capable of carrying HD signals as part of a domestic cable service. However, optical fiber is now far more cost effective than copper so it si increasingly used for trunks with copper links carrying signals the last few feet into a home. Some are now taking fiber right into the home. Regarding video signals within the home, co-ax cable is used to carry composite video (standard definition color signals) and this will not carry HD signals. This is purely because coaxial interfaces for HD in domestic equipment. Coaxial cable is still used widely in broadcast environments to carry SD and HD signals.
What is the difference between Comcast's cable service and Verizon's FIOS?
Using cable industry jargon, cable TV providers don't use optical fiber in the 'last mile.' This means that they use coaxial cable from the main nod in a neighborhood for the last stretch of their network to connect end users. The FIOS technology uses fiber optic cables up to 'the curb,' which means that the TV, phone, and Internet signals coming to your home are carried for the most part by laser beams. Only the wiring inside the home is made up of coaxial cable. One laser bean (Verizon is using three for TV, Internet, and phone) is proven to have more capacity than any commonly used coaxial cable. It is believed that the capacity of optical fiber to carry data is almost limitless.just see www.whyisfiosbetter.viviti.com
What is SPDIF?
S/PDIF or Sony Philips Digital Interconnect Format is a standard/protocol that specifies transmission of audio signals from one device to another in digital format. Both coaxial electrical cable and an optical fiber cable can be used to carry signals in S/PDIF format. - Neeraj Sharma
