Fiber Optical Networking

Enterprises are quickly evolving with new network devices to improve communication and security. Power over Ethernet (PoE), a way to deliver electrical power over LAN cables to network devices, has been widely deployed to provide power to various endpoints in the enterprise environments. If you want to upgrade you network to PoE, one way is to deploy a PoE switch. This paper will provide an overview of the PoE technology and PoE switches . What Is a PoE in Networking? Power over Ethernet, also known as PoE, is a networking feature defined by the IEEE 802.3af and 802.3at standards. POE is able to combine the two connections into one Ethernet cable so that single network cable will transmit both data and 25W of electricity. By this way, it can minimize the number of wires when installing the network, which realize the lower cost, less downtime, easier maintenance, and greater installation flexibility in networking. Why Use PoE? Because PoE is allowed to use one cable for bo

With the development of Cloud services and networking, a series of high performance 40G/100G white box switches have been introduced. The goal is to provide Web scale organizations and service providers more control and flexibility in their data center networks. So what are white box switches? White box switches refers to the ability to use 'generic,' off-the-shelf switching (or white box switching) and routing hardware, in the forwarding plane of a software-defined network (SDN). Moreover, white box switches rely on an operating system (OS), which may come already installed or can be purchased from a software vendor and loaded separately, and then integrate with the deploying organization’s Layer 2/Layer 3 topology and support a set of basic networking features. On the whole, OS is an integral part of white box switches, and the rise of SDN has brought white box switches into the public eye. Next, let’s take a closer look at white box switches. OS Defines White Box Sw

Today's data centers and telecommunication environments heavily depend on the foundation of the optical network. So what makes your optical network different to others? The design and performance of the pre-terminated optical cabling systems will contribute more to your data environments. It’s achievable with FS ultra high density solutions that take your data environments beyond the next level. This article will mainly talk about the ultra high density MPO/MTP cassette in data centers. MPO/MTP Cassette Overview MPO/MTP cassette is a module, which is used for interconnect or cross connect if the distance between two devices is too long. As a pre-terminated fiber product, MPO/MTP cassette is loaded with 12 or 24 fibers and have LC or SC adapters on the front side and MPO/MTP at the rear. The cassettes come in a variety of connector styles and modes, including multimode, single-mode, SC, LC, etc. It is designed to reduce the installation time and effort associated with conn

Today, more and more cables are used in data centers, thus high-density cable management devices become more popular and essential than before. Taking FHD fiber enclosure as an example, a high density 1RU rack mount fiber enclosures can hold up to 4 HD fiber adapter panels (FAPs) or 4 HD MPO/MTP cassettes. And now, he new FHX series ultra HD fiber enclosures have been launched, which efficiently optimize space utilization and save more cost in rack cable management. So, let’s learn more about FHX ultra HD fiber enclosures . Rack Mount Fiber Enclosure Before learning about FHX ultra HD fiber enclosures, we need to know what are rack mount fiber enclosures. In fact, a range of modern rack mount enclosures conform to the DIN 41494 and IEC 291-1 international standards. They are available in various rack unit configurations, such as 1RU, 2RU, 3RU, 4RU and 6RU. And they are designed in cable patching, storage and protection for rack fiber cable management in the data center. The rac

The 10G SFP+ modules allow a wide variety of 10 Gigabit Ethernet connectivity options for enterprise, data center, and service provider transport applications. A single piece of hardware can accommodate a wide variety of cable and connection types, simply by substituting transceiver for the connector being used. Unfortunately, this also means that finding the right SFP+ transceiver for your application can sometimes be confusing and difficult, because many connection types exist: SFP-10G-SR, SFP-10G-LR, SFP-10G-LRM, SFP-10G-ER, SFP-10G-ZR, SFP-10G-T-S, CVR-XENPAK-SFP10G and CVR-X2-SFP10G. This article mainly talks about the difference between Cisco SFP-10G-SR and Cisco SFP-10G-LR. Overview of SFP+ The SFP+ is the enhanced small form-factor pluggable. It is also called SFP 10G to avoid confusion with the 1G version (SFP). It has the same shape as the SFP, but SFP+ can support data rates up to 10 Gbit/s. Specifically, it can support 8 Gbit/s on Fibre Channel and 10 Gbit/s on Gigab

With the introduction of IEEE 802.3an 10GBASE-T, it was determined that a new category of twisted-pair cabling was required to guarantee performance of the 10G network. Most of the time, Cat5e is suitable for 1G network. But now, many streaming media applications can be seen everywhere, the demands for faster data rates will be increased. These new applications are really pushing the limits of Cat5e cabling. Therefore, Cat6 will be a successful choice to deploy a new cabling system. So what is Cat6? What is the difference between Cat5e and Cat6? And so on. This article will provide simple answers to these questions. Q1: What Is Cat6? A: Cat6 is a standardized twisted pair cable for Ethernet and other network physical layers that is backward compatible with the Cat5/5e and Cat3 cable standards. Cat6 cables have a tighter twist in the cables allowing for two-way communication, which eliminate some or all cross talk with other cables. The cable standard provides performance of up to
