Introduction to Semiconductor Optical Amplifier (SOA)

Optical amplifier, with the introduction in the 1990s, conquered the regenerator technology and opened doors to the WDM technology. It is mainly used to amplify an optical signal directly, without the need to first convert it to an electrical signal. There are many types of optical amplifiers, namely Raman amplifiers, erbium doped fiber amplifiers (EDFAs), and semiconductor optical amplifier (SOA)….

Cisco Vs Huawei – Which One is the better Choice for Ethernet Switches?

Cisco, as the big brother in the telecom industry, has dominated the market of networking devices (like routers and switches) for a long time. No one can compete with him. Huawei, however, is the rising star in the Chinese market. It ranked 83rd in the latest Fortune 500 list on July 23, 2017. Many people assume that in the near…

Mikrotik Vs Ubiquiti – Which One is Better for Home Network?

Ubiquiti Networks and Mikrotik were the rising stars in telecom field for the past year and a half, I have heard various fiber optic technicians telling me that Ubiquiti is better suited wireless applications while Mikrotik is excellent at what it does best—routers. As the cheap and reliable alternative to Cisco expensive equipment, Mikrotik has a learning curve not many…

Four Basic Elements in a WDM System

We know that fiber can carry more data over long distances than any other physical medium. That makes fiber a very precious material. And how to make the most use of your fiber plant becomes a question. So there comes Wavelength Division Multiplexing (WDM). Why Should We Deploy WDM? WDM can multiply your fiber capacity by creating virtual fibers. The…
