Nowadays, fiber optic cable is a popular medium for both new cabling installations and upgrades, including backbone, horizontal, and even desktop applications. Although fiber offers various advantages over copper, copper still has a space in telecommunication networks, for example, direct attach copper cables, like HP JD096C 10G SFP+ direct attach copper cable or Cisco QSFP+ breakout cable (Cisco QSFP-4SFP10G-CU5M). The twisted pair cable has been widely deployed for telephone line networks ever since it was first developed in 1881. Today, it has already been extended worldwide mainly for outdoor land lines offering telephone voice services.

What Is Twisted Pair Cable

As a kind of copper wiring, twisted pair cable is made by putting...

Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. Compared with copper cable, fiber optic cable can support longer transmission distance, high speed, high bandwidth, etc. However, not everything is perfect. There are still some factors that may influence the transmission distance over fiber cables. This article will introduce the most common factors that limit the data transmission distance.

Fiber Optic Cable Type

Generally speaking, the maximum transmission distance is limited by dispersion in fiber optic cable. There are two types of dispersion that can affect the optical transmission distance. One is chromatic dispersion, which is the...
