Optical amplifiers serve as an integrated part of long haul data transmission. Fiber optical transponders and fiber optical amplifier are used in the WDM fiber optic system, and it makes WDM transmission possible. In recent years, fiber optic CATV EDFA System, especially the 1500nm optical fiber CATV System, is being rapidly developed in our country. What is EDFA? Erbium Doped Fiber…

FTTx technology plays an important role in providing higher bandwidth for a global network. And FTTx (fiber to the x) architecture is a typical example of substituting copper by fiber in high data rate traffic. According to the different termination places, the common FTTx architectures include FTTH, FTTB, FTTP, FTTC, and FTTN. This article will introduce these architectures respectively. What…

A network is essential for establishing communications among devices such as computers, routers, or fiber switches to operate over the area they cover. LAN (Local Area Network), WAN (Wide Area Network) and MAN (Metropolitan Area Network) are the three most prevalent types of networks that are utilized today. There are some similarities and differences between them. LAN vs WAN vs MAN,…
