Each power supply has a separate power cord to support its work. Server power cord connecting the servers and PDU (power distribution unit) plays a critical role in this process. Since the power cords standard for connector types and voltage levels varies from country to country. It’s important to choose the most suitable one for network systems. This post intends to give a simple introduction to server power cords and their applications in different systems. Power Cords Overview Usually standard power cords or jumper power cords are available for connection to the server. Power cord consists of three necessary parts: plug, cord and receptacle. And there are many different types of power cords used all over the word. The most commonly seen types are the IEC60320 power cord and NEMA power cord. The former one is often used in US. While the latter is usually seen in North America and other countries that use the standards set by the NEMA. Among these two types of power cords,

DWDM MUX/DEMUX plays a critical in WDM network building. 16 channels transmission is very common in DWDM networks. How to realize it in a simple way? This article intends to introduce two solutions to achieve 16 channels with different types of components. Which one is more cost-effective and competitive? The comparison between the them also will be explored. Hope it will help you when choosing fiber mux for your DWDM networks. Solutions to Achieve 16 Channels Transmission in DWDM Network In order to illustrate the solution more clearly, I take two types of DWDM MUX/DEMUX as an example. One is the traditional 16 channels dual fiber DWDM MUX/DEMUX. Another is two FMU 8 channels dual fiber DWDM MUX/DEMUX. The latter has an expansion port. Solution One: Using Traditional 16 Channels DWDM MUX/DEMUX The 16 channel DWDM MUX/DEMUX is a passive optical multiplexer designed for metro access applications. It’s built fiber mux and demux in one unit and can multiplex 16 channels on

CATV technology has matured steadily over the past several years, and has expanded into diverse applications. However, as the quick expansion in technology and services, it’s important to improve CATV network component performance for higher visual and audio signals transmission. Optical amplifier for CATV application is the key element in such transmission. This post intends to give a clear introduction of optical CATV amplifier and its application in CATV transmission. Introduction to CATV Amplifier CATV amplifier is also a type of EDFA (Erbium Doped Fiber Amplifier) amplifier which is the most popular optical amplifier in optical network communications. It is mainly used to amplify damped TV signals (compensation for loss) for improved signal quality before sending them to each subscriber. Moreover, CATV amplifiers not only amplify the signal, but also amplify the noise on the line, and bring some return loss. That’s why a quality CATV amplifier price is a little high, becaus
