Dense Wavelength Division Multiplexing (DWDM) is anoptical multiplexingtechnology used to increase bandwidth overexisting fiber networks.DWDM works by combining and transmittingmultiple signals simultaneouslyat different wavelengths on the samefiber. The technology createsmultiple virtual fibers, thus multiplyingthe capacity of the physicalmedium. DWDM provides ultimate scalability and reach for fiber networks.Withoutthe capacity and reach of DWDM systems, most Web…

Physically, PVC and LSZH are very different. PVC are very soft; LSZH are more rigid because they contain the flame retardant compound, and they are aesthetically more pleasing. A PVC cable (made of polyvinyl chloride) has a jacket that gives off heavy black smoke, hydrochloric acid, and other toxic gases when it burns. Low Smoke…

FTTP (fiber-to-the-premises) This term is used either as a blanket term for both FTTH and FTTB, or where the fiber network includes both homes and small businesses. FTTH (fiber-to-the-home): Fiber reaches the boundary of the living space, such as a box on the outside wall of a home. Passive optical networks and point-to-point Ethernet are…

What is 5G? 5G is the term used to describe the next-generation of mobile networks beyond the 4G LTE mobile networks of today. As of mid-2016, there was no standard so the definition is still very fluid. It is assumed that 5G networks will not become commercially available until the 2020 timeframe. The International Telecommunications…

Differences between 5G and 5GHz 5G and 5 GHz Wi-Fi technically, they do have some things in common. First, both terms revolve around wireless technology. More specifically, 5G is the cellular standard for digital signals used by mobile phones, in effect an upgrade from the previous 4G mobile network standard. 5 GHz refers to the…
