Comparison Between Different Fiber Optic Cable Types

图片
Nowadays more and more fiber-based networks have been built in the backbone and risers environment. Both multimode and single-mode fibers are available for the applications. But different fiber types have briefly different limitations for speed and maximum distance. These characteristics they possess and the way cause the fiber to operate determine the application to which a given fiber is most appropriate. Today’s article will offer you some information about the classification of fiber optic cables and the difference in speed and distances. Difference Between OM Multimode Fibers Multimode fibers, according to the specification and briefly by their bandwidth performance are commonly classified into OM1, OM2, OM3 and OM4. Each multimode type has different transmission data rates, link length and bandwidth for specific protocols, applications and transceiver types. Table 1 outlines the international standards organization classification for multimode fiber which describe the strength f…

The Do’s & Don’ts of UTP Cable Installation

图片
With the technology evolving rapidly and new products keep coming out, optical technicians have to upgrade their knowledge accordingly. Take the UTP (unshieled twisted pair) network cabling as an example, lately telecommunication industry witnessed the evolution of copper cable from the old cat 3, cat 5 to the existing popular cat 5e and cat 6 cable (even to the cat 7 cable or cat8). Therefore, cable installers attach great importance on the TIA-568B installation. Even the experienced installer may discover the problems that they have never been aware of before. Today’s article is going to present all the detailed information necessary to complete a fully compliant TIA-568B UTP installation. Overview of UTP Cable & TIA-568B Wiring Standard Designed primarily for data transmission in local area networks (LANs), UTP network cable is a 4-pair, 100-ohm cable that consists of 4 unshielded twisted pairs surrounded by an outer jacket. Each pair is wound together for the purposes of cance…

Which Is Perfect for Your Business – Data Center or Server Room?

图片
Every enterprise or small business that needed a server was required to invest in its own infrastructure, hardware and maintenance solutions, with all the equipment accommodated in a dedicated room of the office. However, thanks to the cloud technology and the rapidly increasing availability of fiber connectivity, other options like data center have opened up in recent years. So how should you decide whether you will go with a data center service or a server room? To ease out the confusion, today’s article presents the differences between data center and server rooms. Data Center & Server Room Of course, every company has their own needs, and what works best for one company is not necessarily going to be the best solution for another. A server room is a room that devoted to store servers. A data center, to this purpose, is a whole building specially designed to contain and support a large amount of computing hardware of some sort. The main difference between them is the size, but …

Why Recommend Fiber Over Copper in 2017?

图片
2017 is coming in less than a month, looking back, in the communication field, the old remaining dilemma between fiber and copper is still left behind. People are struggling about whether they should hold on to the tried-and-tested copper cables that are sufficient so far, or make the leap into the future, and go fiber optic. From a technical perspective, the case for switching to fiber is growing ever stronger. Using a fiber system will lead to more bandwidth, reliability, less down time and end up saving you money. Today’s article will make you understand the trend for switching to fiber. More Bandwidth, Faster and Longer People are aware that fiber optics is winning out over copper because of its higher performance, namely more bandwidth, faster speed and longer link distance. Bandwidth decides how much data you can receive and send. Copper cable that can be used for 10 Gigabit cabling, and 100 Gigabit cables is at the point of topping out, but these data rates can be sent only for…

Telecom Cable Rating: CMP or CMR Cables

图片
We usually use terms—CMP, CMR, PVC and LSZH to describe telecom cables, but do you know what these terms really mean? And, more importantly, which one does your project actually need? The article below will briefly outline many industry cable types, along with their features to help you have a better understanding of them. Plenum Rated Cables CMP cable refers to the communication plenum cable that is laid in the plenum spaces of buildings. Plenum rated cable or just plenum cable is jacketed with a fire-retardant plastic jacket of either a flame retardant low-smoke polyvinyl chloride (PVC) or a fluorinated ethylene polymer (FEP). Owing to its material in this network cable, it doesn’t emit a toxic smoke when they burn. Plenum rated cables are slower to burn and produce less smoke than other cables. As seen in the above image, plenum refers to the air handling space. In a standard commercial building, the plenum is the space between the drop ceiling and the structural ceiling. In reside…
