Which Kind of Ethernet Cables Should I Use?

Not all Ethernet cables are created equally. They are grouped into sequentially numbered categories (“cat”) based on different specifications. Cat 5e, Cat 6, Cat 6a, Cat 7 cable are the most common kinds of Ethernet cables. How to tell the difference between them and choose the suitable one for your network?

First and foremost, let’s have a rough sketch of their ...



High-Speed Copper Transceivers Overview

The last few decades have seen the broad adoption of fiber optic transceivers used in optical communications for both telecommunication and data communications applications. However, would the copper connectivity withdraw from the market? Copper medium usually doesn’t require any transceivers, as they are part of the interface module. However, in order to cut down ...


Six Basic Procedures for Fiber Cable Testing

Customers for fiber optic cable installations usually require documentation of test results before accepting and paying for the work. Testing needs to be done carefully to ensure the measurements are accurate and reliable. A definitive repertoire of tests, known as the "essential six," can benefit the inexperienced system engineer. Six basic test procedures measure distance,...


Twisted Pair Cabling Overview

Nowadays, fiber optic cable becomes one of the most popular mediums for both new cabling installations and upgrades, including backbone, horizontal, and even desktop applications. Though fiber offers a number of advantages over copper, copper still has a space in telecommunication networks, for example, direct attach copper cables, like HP JG081C 10G SFP+ direct attach copper...



Pre-terminated Fiber Cabling for 40G/100G Data Center Applications

The deployment and termination of fiber optic cabling in data center usually cost a lot of time and labor. However, with the increasingly need for high density cabling in 40G/100G data centers, fiber cabling and termination become even more difficult and time-consuming if traditional field termination methods are still applied. And fiber optic networks are becoming more and more...

10 Gigabit Ethernet (10GbE) now is a commonplace for current network backbones and data centers to support high-bandwidth applications. And with the continuous advancement and improvement in 10GbE technology, it has extended its applications to midmarket networks for the purpose of ensuring faster data transmission and better network performance. How to achieve an efficient and...


How to Properly Handle Optical Fiber?

Fiber optic cables have been more and more widely used in all kinds of applications. You can use fiber optic jumper cables to connect end devices or network hardware to the structured cabling system and one popular type of fiber optic jumper cables, MPO cable, is a good solution for your high density applications. The technique to handle optical fiber can have a significant...


Factors to Consider for 10 GbE Network Deployment

Nowadays, 10 Gigabit Ethernet network has been very popular and been employed by large amount of enterprises in their corporate backbones, data centers, and server farms to support high-bandwidth applications. To achieve a reliable and cost-effective 10 Gigabit Ethernet network, here are several factors that you should take into consideration for the deployment.



Cabling Solutions for 40G Short Reach QSFP+ Transceivers

40G parallel optical transceivers use four 10G channels to transmit and four 10G channels to receive signals over a 12-fiber assembly. The middle four fibers remain unused or dark. Each fiber either transmits (Tx) or receives (Rx) 10G traffic at a single wavelength. 40gb QSFP+ is the dominant transceiver type and popular choice for 40 Gigabit Ethernet applications. Among all...


What Are Simplex, Half Duplex and Full Duplex?

When talking about fiber optic jumper cables, such as LC LC multimode duplex fiber cable or LC SC single-mode simplex fiber optic patch cable, we came across simplex and duplex, or full duplex. What are simplex and full duplex? They are two kinds of communication channels in telecommunications and computer networking, which provide pathways to convey information. In fact, other...
