Whats the Problem With DSL Deployment?
Copper lines have it rough. Twisted pairs get spliced and respliced. They’re subject to a wide variety of vibrating, radiating, noise-making elements in the environment, not to mention bad weather if they’re aerial, digging cuts and contamination if they’re buried. Loop design parameters such as working length, cable gauge, and the number and location of add-on physical components can be expected to affect DSL performance in a variety of ways. These are some of the most common factors that disqualify loops for DSL: Cable length – DSL was designed deliberately to use low power, to avoid interfering with other transmissions. But that also means its signals can get lost in the background noise if they have to travel over too long a cable. Right now, 12 to 15 thousand feet is the usual limit, as much as 18 thousand feet under otherwise ideal conditions. Load Coil – is a piece of electrical hardware that was widely installed in an earlier time to improve voice transmission by effectively bo
