How many no of twist per feet in cat 6 cable?
Cable twisting length is not standardized. In a typical cable there are 1.5 to 2 twists per cm in Cat-5(e) and 2 or more twists per cm in Cat-6. One cm equals 0.393701 inches. Within a single cable, each coloured pair have different twist lengths. Each cable manufacturer's twists per pair is usually different from another manufacturer.
What are the number of twists in communications cable pairs?
Twists in telecom cable pairs lowers their tendency to radiate electromagnetic radiation, also known as crosstalk ,or overhearing in adjacent circuits. If you separate the twists for jointing purposes you increase em radiation at that pont. Twisting also keeps the loss of signal per metre to a low level.Pairs are twisted round each other at a rate of about 25 twists per metre and the pairs are then twisted again around the core of the cable.
What is the allowable propagation delay for a 100 meter Category 5 cable at 10 MHz?
200ns
Type of cable used in active air circulating spaces of an HVAC system?
The type of cable is called 'plenum' cable. There will be a P in the cable designation. For instance:CM means communication cable not suitable for plenums.CMP means communication cable suitable for plenums.
What is maximum allowable cable length between phone jack and modem according to V9x specifications?
10 feet
What is allowable resistance of the cable in mergers test?
A good number on a megger test should be around 2 megohms.
Why do UTP and STP have twists?
STP - Shielded Twisted Pair is twisted to reduces crosstalk. Crosstalk is when the signal crosses wire and reduces the communication quality. Twisting the pairs reduces the signal transmission to other wires in the cable "pack". Twisting them increases the length the cable can be run. Category 5 has a usable length of 100m, 330ft.
Communication uses cable lines that already exist in millions of households?

How the twist in twisted wire cable reduce the noise effect?
The twists in the wire cancels the magnetic coupling (or nearly all of depending on if there are even or odd number of twists). See Clayton Paul's book on Introduction to EMI/EMC.
