400G: Titanic Revolution in Data Center

图片
Nowadays, with the rapid growth of data centers, people’s need for better network capacity and higher speed is increasing dramatically. Consequently, the Ethernet speed upgrade has become a hot issue in recent years. The past few years have witnessed the titanic revolution of Ethernet speed from 1G, 10/25G to 200G. And 400G will be the next driving force of the data center. Recently, FS has launched several 400G direct attach cables to follow the trend. Then what is 400G Ethernet network? And what is new in the current 400G market? This post will give you the answer. What Is 400G Ethernet? 400G Ethernet is also known as 400 Gigabit Ethernet. It is developed by IEEE P802.3bs Task Force and is published in 2017. And 400 Gigabit Ethernet is an advanced version of 100 Gigabit Ethernet because the speed of 400 Gigabit Ethernet is four times as fast as 100 Gigabit Ethernet and it can provide a denser configuration than 100 Gigabit Ethernet. Besides, the products of 400 Gigabit Ethernet

How to Realize Long Distance 40G Network With DWDM Solution

图片
Nowadays, many customers are in need of better data storage capacity and long-distance transmission. Faced with this phenomenon, FS has developed DWDM series products such as DWDM Mux, OADM, OEO and so on. And FS is always committed to meeting the specific needs of our customers and providing customized DWDM solutions for them. Currently, one of our customers from the NineStar Connect company is faced with a problem of long-distance data transmission and asks FS for help. Let’s see how FS company tackles this problem with DWDM solution. Background As mentioned above, this customer is seeking for solution for longer distance transmission. This customer wants to realize 48km transmission, while the maximum transmission distance of 40G QSFP+ optics is limited to 40 km and each 40G interface requires a dedicated fiber between sites. Besides, this customer told FS that their network has a dark fiber linking two sites beyond 40km, but they don’t know the link loss between these sites. F

How to Realize 100KM DWDM Network With FMT 4000E

图片
Nowadays, DWDM technology has been one of the most commonly used technology in the optical transport network (OTN) applications due to the increasing bandwidth need of telecommunication providers. Faced with unpredictable traffic requirements and increasing bandwidth demands, FS has developed a new standardized optical transport solution, which called FMT WDM transport platform. And this FMT WDM transport platform is divided into four specific series according to different transmission distance, including CWDM solution FMT 1800, DWDM solution FMT 1600E, 4000E, 9600E. In this post, we will take FMT 4000E optical transport platform as an example to illustrate how does this transport platform realizes 100km network connections and its advantages. What Is FMT 4000E DWDM Network  Transport Platform ? As mentioned above, FMT 4000E DWDM network transport platform is one type of the FMT WDM transport platform series. This optical transport platform is a 4U managed chassis. It is equipped

WDM Mux/Demux Transmission Modes Overview

图片
WDM (wavelength division multiplexing) is one of the technology which can expand the capacity of a fiber optic network without requiring additional fiber, and it plays a very important role in long-haul data transmissions. In a WDM system, there is an important component called WDM Mux Demux (multiplexer/demultiplexer), which can multiplex multiple wavelengths into one single fiber to increase the network capacity. Usually there are three transmission modes in WDM networks: duplex bi-directional transmission, simplex bi-directional transmission and simplex uni-directional transmission. And this post will illustrate some detailed information about three transmission modes of WDM Mux/Demux. Duplex Bi-directional Transmission Mode In this transmission mode, one fiber only transmits one direction optical signal and the reverse optical signal will be sent by another fiber, which is often seen in dual fiber WDM Mux/Demux. And the same wavelengths can be used in two directions. Take the

Quick View of Copper Patch Panel Types

图片
Nowadays, patch panels play an essential role in network functionality. By centralizing cables in one place, patch panels make it easy for network administrators to move, add or change complex network architectures. And patch panels can be divided into two types, that is fiber patch panel and copper patch panel. The copper patch panel is designed for both shielded and unshielded copper cables like Cat5e, Cat6, Cat6a. It is commonly used in a local area network (LAN). This post will introduce some common copper patch panel types for you. Common Copper Patch Panel Types In the next part, some detailed information about common copper patch panel types will be illustrated. Cat5e Patch Panel In general, Cat5e copper patch panels can be divided into shielded and unshielded patch panels. Cat5e shielded patch panels are designed for high EMI environments, while unshielded patch panels are used in areas where has no high power electrical wires. And Cat5e copper patch panel is availabl

UTP vs STP vs SFTP: Difference and Application

图片
Generally, in terms of different bandwidth, network cables can be divided into Cat5, Cat5e, Cat6 and other common types. Based on the function of shielding, network cables can also be grouped into UTP, STP, SFTP. And this post will shed light on some detailed information about UTP, STP, SFTP and help you to have a deep understanding about them. UTP UTP is also called unshielded twisted pair, and unshielded means no additional shielding like meshes or aluminum foil. It is a ubiquitous type of copper cabling used in telephone wiring and local area networks (LANs). UTP cables use eight wires grouped in four pairs, each composed of a solid-colored wire and a stripped wire. The maximum length of a single segment of UTP cable should not exceed 295 feet to avoid data loss. And UTP is the thinnest and most flexible Ethernet cable on the market, which is easy to work with and install. STP STP is also known as shielded twisted pair. It incorporates a conducting shield built of metallic

12U Wall Mount Cabinet Recommendation

图片
Nowadays, cabinets play an important role in the data center because they can be used to achieve high-density cabling and improve the efficiency of data center network management and operation. According to different applications, cabinets can be divided into sever cabinets and network cabinets. Server/network cabinets are generally divided into two types. There are floor cabinet and wall mount cabinet. As for wall mount  cabinet , 6U,9U, or 12U types are commonly seen in the market. This post will focus on two types of 12U wall mount cabinets, some detailed information about them will be elaborated below. 12U Wall Mount Cabinet Overview For 12U, the “U” stands for the rack unit that is an EIA standard measuring unit for rack mount type equipment. 1U is equal to 1.75″ in height. A 12U wall cabinet means it would have 21″ internal usable space (12×1.75″). As for the wall mount cabinet, it is designed to be attached to the wall so as to save spaces. The 12U wall mount cabinet uses
