One of the key tasks of a data center manager is to plan the infrastructure of the data center based on actual needs and future needs. So how do you build a database of the best and most efficient data centers? This tutorial will provide you an answer.The necessary components for building the best d

40G Ethernet comes to be more dominated in the modern network with its high transmission rate. 40G QSFP+ optical module is an important component of 40G Ethernet, which provide high density 40G Ethernet interface for the data centers of the network service providers. Now a verity of 40G QSFP+ optica

With the maturity of wavelength division multiplexing (WDM) technology, CWDM & DWDM multiplexer / demultiplexer have been widely used in fiber extension application, it not only save the fiber resources, but greatly extend the network capacity as well. Anyone who has seen CWDM & DWDM multiplexer / d

In the Coarse Wavelength Division Multiplexing (CWDM) system, there are two main types of CWDM multiplexer / memultiplexer: dual fiber bidirectional CWDM multiplexer / memultiplexer and single fiber bidirectional CWDM multiplexer / memultiplexer, of which dual fiber bidirectional CWDM multiplexer /

Dense Wavelength Division Multiplexing (DWDM) is a wavelength division multiplexing (WDM) technique that extends the transmission capacity of existing fiber networks. It can multiplex multiple optical carrier signals onto an optical fiber for transmission and save a lot of fiber resources in long-di

With the popularity of smart phones, laptops and other mobile devices, WiFi has become an indispensable part of the home and enterprise networks, and there are many ways to deploy WiFi networks. Among them, through the PoE technology is considered as the most commonly used ways to build enterprise w

Dense Wavelength Division Multiplexing (DWDM) network is the most effective and feasible solution to achieve long-distance fiber expansion, which has been widely recognized by the people. In practice application, apart from increasing network bandwidth, we also need to focus on the fact that how to

Wavelength division multiplexing（WDM）technology commonly divided into coarse wavelength division multiplexing (CWDM) technology and dense wavelength division multiplexing (DWDM) technology, which can be widely used in various optical telecommunication network, of which the channel density of DWDM sy

Over the past few decades, communication network has undergone a milestone development, software defined network (SDN) is a new network structure which sprang up in recent years, it uses OpenFlow technology to separate control planes and data planes from network equipment, thereby to achieve flexibl
