What is the “Cloud” and why do I need Fiber to get there?

by Fiber-MART.COM
Cloud computing is one of the hottest buzzwords in technology. It appears 48 million times on the Internet. But exactly what is cloud computing? In general terms the cloud refers to using a network of remote servers hosted on the Internet to store, manage and process data, rather than a local server or a personal computer.

According to research by Nasuni, there is over 1 Exabyte of data currently stored in the cloud. Okay if you are not familiar with Exabyte that equates to 1,073,741,824 Gigabytes of data. And this number is growing exponentially every day.
 
Technology has evolved almost immeasurably in the past several decades. To access the tremendous amounts data we need fiber networks that can carry Terabits—one trillion bits per second. That is an enormous amount of information passing at the speed of light through this one strand of fiber the size of a human hair.
 
 
Data centers of the past were copper-based with multiple DS1 and Digital Signal 3 (DS3, 45 Mbits/sec) lines handling the load of servers to an Optical Carrier 3 (OC3, 155 Mbits/sec). This OC3 would connect the servers to the network cloud or outside world. Copper dominated in a data center environment and the only fiber installed was that single line connecting the servers to the network cloud. 
 
Today with applications such as iTunes, Netflix, Hulu and others and cloud computing/hosted servers, backup and storage, Microsoft CRM, hosted private branch exchanges (PBXs), web analysis tools and web hosting are driving enormous growth in data center server deployments. Data centers are offering rates at DS1, DS3, 5 Mbits/sec, 10 Mbits/sec, 20 Mbits/sec and up to an OC3, all connecting to the outside world via 10-Gbit Ethernet or 100-Gbit Ethernet connections from multiple providers. To alleviate risk, the data center architecture is evolving away from the previous copper DS1 and DS3 panels, to fiber panels with multiple connections to the client and to the cloud for redundancy.
 
As the amount of data in the cloud continues to increase, more data centers will be built, more fiber will be installed and older copper deployments will become new fiber installs. fiber-mart.com was established to help new contractors who are getting into the fiber field succeed. From training your technicians, equipment sales and rental and a sounding board to help you through job opportunities, whatever the job you have, we have the solution.

Common Armored Fiber Optic Cables

  Armored fiber optic cables are often installed in a network for added mechanical protection, as they have extra reinforcing in the cable housing to prevent damage. Two types of armored fiber optic cables exist: interlocking and corrugated. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers ruggedness and superior crush resistance. Corrugated armor is a coated steel tape folded around the cable longitudinally. It is found in outdoor cables and offers extra mechanical and rodent protection.   The Structure of an Armored Fiber Optic Cable In basic armored fiber cable designs, the outer sleeve provides protection against wind, solvents, and abrasion. This outer sleeve is usually made of plastic such as polyethylene. The next layer between the sleeve and the inner jacket is an armoring layer of materials that are difficult to cut, chew, or bu

what the Differences Between FBT Splitter and PLC Splitter

  In FTTx and PON architectures, optical splitter plays an increasingly significant role to create a variety of point-to-multipoint fiber optic networks. But do you know what is a fiber optic splitter? In fact, a fiber optic splitter is a passive optical device that can split or separate an incident light beam into two or more light beams. Basically, there are two types of fiber splitter classified by their working principle: fused biconical taper splitter (FBT splitter) and planar lightwave circuit splitter (PLC splitter). You may have one question: what’s the difference between them and shall we use FBT or PLC splitter?   What Is FBT Splitter? FBT splitter is based on a traditional technology to weld several fiber together from side of the fiber. Fibers are aligned by heating for a specific location and length. Because the fused fibers are very fragile, they are protected by a glass tube made of epoxy and silica powder. And then a stainless steel tube covers the inner glass tu

Introduction of Optical Fiber Couplers and How Do They Work?

 What are optical fiber couplers? A fiber optic coupler can be defined as an optical component used with one or more input fibers and several output fibers in fiber optic systems. A coupler essentially puts two or more cores of fibers together to connect. The simple coupler is the fused fiber 2x2 coupler. Couplers are used as multiplexers that are resistant to certain wavelengths. A fiber output depends on the wavelength of light and the frequency of polarization. The fiber refractive index also plays a significant role in the performance. Let’s checkout how do optic couplers work to understand this better. How do fiber optic couplers work? Either fiber optic couplers separate optical signals into multiple paths or combine multiple signals in one direction. Optical signals are more complicated than electrical signals, making it more difficult to design optical couplers than their electrical copy. Unlike electrical currents, the optical signal consists of a stream of signal carriers, in
