Open networking possesses distinct interpretations in different fields. It gradually picked up steam when adopted in open network switching, attracting flocks of vendors to take a share from the giant and burgeoning market. What is open ne…
The network switch has now grown in the same way that the server was developed in the market. Proprietary switches are now challenged by the white box switches that bring open source software. There are many network operation systems that …
Lots of customers have found the letters “CM”, “CMR” and CMP” in the product description when purchasing copper cables like Cat5e cable and Cat6 cable. These terms are the most common cable jacket ratings specified by the National Electric…
As switch stacking, the premium feature of few network switches, evolves as a core competence of Ethernet switches in the market, vendors strives to release varies stackable switches and produce switch stacking tutorials for customers. Thi…
24-port Ethernet switch not only adds more ports for your home router, but also becomes a preferable option for enterprise networks, with dramatically decreased price, expanded feature sets and improved ease of use. Most 24 port switch pri…
The entire network today has expanded and there emerge faster Ethernet switch like gigabit Ethernet switch and even 10gb switch which provide us with higher information switching speed. However fast they can forward the data packets, they …
The computer switch though has long existed in the market, few people can speak on it with great familiarity. As the network expands, the computer switch grows more sophisticated and diversified. This post sheds light on the computer switc…
The Internet switch, since its birth, has been growing rapidly not only in function but also in performance. Experts have researched and developed generations of Internet switches, while the majority of people may be new to the devices, no…
With the development of technology, no matter how far you are away from families, you can communicate with them at any time in any places. The same is true to the optic communication, regardless of the physical locations of two hosts or th…
With the development of technology, network switch grows not only in speed like the migration from gigabit Ethernet switch, to 10gb switch, 40gb switch and 100gb switch, but also in complexity to acquire more functions and meet complicated…
Why should fiber optic cable not be tightly bent? Are fiber optic cable fragile? These issues are what users care about when deploying fiber patch cables. Usually, fiber optic cable is made from two bend sensitive materials: plastic or gla…
Optical transceivers usually work coordinately on a pair of network switches. As switch is responsible for directing the flow of data, optical transceiver works for transforming light to data or the opposite. Then how do two transceiver mo…
As we slip further in the internet era, the internet boom pushed service providers to find a method to increase the capacity on their network in the most economical way. Therefore, two technology come into our sight: DWDM vs. OTN, the tech…
NAT, which is critical to the IPv4 networks we still use today, has been hotly debated as the IPv6 grows with more addresses. However, since the IPv6 is not full-fledged, the existence of NAT still makes sense. Here I will introduce NAT de…
As the network grows, the network equipment producers flourish, bringing many different exclusive products into the market. How to manage or operate so many equipment as the different vendors own diversified CLI and web interface to debug …
We know that if any chain in the network fails, the operation may break down. Facing this problem, we’ve introduced the stackable switches and together with it is the concept of redundant links. When stacking switches, except the shortest …
Fibre Channel (FC) is a serial I/O interconnect network technology capable of supporting multiple protocols. It is used primarily for storage area networks (SANs). Ethernet (and TCP/IP) is the most frequently used technology these days for…
What Is a Patch Panel? The patch panel is a device that integrates both cable management and termination functions. The patch panel cabling is conducive to the structured cabling as the cables are put orderly on the patch panel. As the int…
Cables are in the right position. Patch panels are terminated. All slack cables are put orderly in the cable manager. Let’s see what is missing? Well, where should the patch panels and cable managers be? Just lying on the ground? If indeed…
Can you distinguish different types of cable manager and tell whether they are applied for vertical or horizontal cable managemen, as well as their practical usage?
The patch panel, a significant element in cabling design, has many ports on it. Through these ports, the cables are located elsewhere in your building. Patch panel at present has fiber and copper patch panel(also known as Ethernet patch pa…
Why is the D-ring horizontal cable manager standing out among all those cable managers? Why you want choose it? Look here.
Increasing bandwidth has always been the most important task of telecom engineers. Through decades of research and engineering effort, 40Gbps and 100Gbps solutions have been used for network applications. But 40G and 100G transceivers can’…
Since the overwhelming growth in data traffic, many data centers are loaded with 10G and 40G based Ethernet switches for 10G to 40G migration. 40G switches allow the configuration of 40G port to act as one port or break out into four indiv…
As 40G connectivity is accelerating, many data centers prepare to migrate from 10G to 40G. But the link distance between 10G and 40G switches is a big challenge. This article can help you extend 40G connection distance. Current 40G QSFP+ C…
SFP is short for small form factor. It refers to fiber optic transceivers supporting 1Gbps data rate. Except SFP, current market is full of various types of fiber optic transceivers, such as QSFP, QSFP+ and QSFP28. At the first sight, thes…
Among so many different Cisco SFP modules, sometimes you may feel confused. Because the differences of some SFP modules are tiny, for instance, Cisco SFP GLC-LH-SM and Cisco SFP GLC-LH-SMD. If you can’t understand the the difference betwee…
Currently 10GbE and 40GbE network are efficient and enough for some users. However, to some large-scale data centers, 40GbE Internet speed can’t meet their demands as the Internet continues to grow in size and traffic. According to researc…
When migrating to 10G data center, you may have two choices: SFP+ or 10GBASE-T technology. 10GBASE SFP+ interface has always been widely deployed for 10 Gigabit ToR (top of rack) witches due to low power consumption. Due to advanced techno…
As we all know, single mode fiber optic transceiver is designed for long distance data transmission and multimode fiber optic transceiver is for short distance link. How to calculate the specific distance that a fiber optic transceiver can…
