  by www.fiber-mart.com Data centers are never ceased their steps to bring greater speed and efficiency to telecommunication and datacoms industries. An enormous amount of data is transmitted, gathered and analyzed everyday, all which requires a vast number of high-bandwidth interconnections between data centers, and people. During these interconnections, fiber optic cables see their heaviest use.   Fiber optic cables  can deliver more bandwidth for voice, video and data applications, and carry thousands of times more information than copper wire. With fiber optic cables, reliable and secure data transmission is ensured. Fiber optic cables are available in single-mode and multi-mode versions based on transmission mode standard. This article puts its focus on the latter version: multi-mode fiber (MMF), discussing MMF from its core size attenuation, bandwidth and manufacturing ways.   MMF: Larger Core Size It’s known that MMF has a much larger core size and cladding diameter, whose diffe

  by www.fiber-mart.com With the rapid advancement of fiber optic technology and trend towards optical communications, fiber optic patch cord has realized its great use in high speed data transmission networks, found in routers, fiber patch panels, media converters and even in hubs and switches. Compared to its previous counterpart, fiber optic jumper causes lower signal loss, delivers more bandwidth and carries more information, becoming more and more popular in cabling installation or upgrading between or inside buildings. Just like the transceiver modules which fall in many types based on different standards, fiber optic patch cables are also available in several kinds, including single-mode/multi-mode, simplex/duplex, MPO/MTP cable, armored patch cord, and so on. This article aims to introduce the last three useful fiber patch cords and their use.   Simplex/Duplex Patch Cables Simplex cable, also known as single strand cables, has one fiber, tight-buffered (coated with a 900micron

  by www.fiber-mart.com Fiber optic joints or termination is a necessary process when installing a network. Every network operators who aim to deploy a next-generation fiber network have to determine how to build a flexible, reliable and long-lasting infrastructure at the lowest possible cost. In general, there are mainly two fiber optic termination methods: splices which create a permanent joint between the two fibers, or connectors that mate two fibers to create a temporary joint. When people decide to use either method, many factors should be taken into account. Today’s article will evaluate both methods from the aspect of cost to help you choose the effective termination method.     Weighting the Two Methods     Besides the features of low loss, minimal reflectance and high mechanical strength, fiber optic termination must be compatible to the environment in which they are installed. Before we come to the cost comparison of these two termination methods, let’s firstly have a brief

  by www.fiber-mart.com A fiber optic data link carries signals for communications, security, control and similar purposes by using transceivers and optical fibers. Designed to protect the fibers, an optical fiber cable should be installed, spliced and terminated with the proper hardware to mate the data link transceivers, and included in a fiber optic cable plant. This cable plant must be selected and installed to withstand the environment, and typically terminated at outlets or patch panels near the communications equipment. It’s connected to the transceiver by short fiber optic jumper. Last blog introduces fiber optic data links: parts, signals and power budget. Today’s blog details another device used in data links: fiber optic cable plant.   Cable Plant Basicst Basics Since the fiber optic cable plant consists of the optical cable which is terminated with the transceiver, this cable plant must be compatible with the performance parameters of the transceivers for the link to operat

  by www.fiber-mart.com Optical fibers  can be divided according to the material they are made of. As mentioned in previous post, optical fibers can be made of glass, but they can also be made of plastic. Both of the materials have their pros and cons.   The fibers made of glass are great for long-distance transmission, but are very expensive. They are divided into two different types: Single mode and Multimode. The main difference between both of them is the core diameter and the number of light bundles in the fiber. Single mode fibers allow only one beam of light to be transmitted, and Multimode fibers can transmit multiple light beams at a time.   As we already said, we also know optical fibers made of plastic, also called POF fibers (Polymer optic fiber). Plastic fibers are used at shorter distances and have a larger core diameter. Their transmission routes are less reliable than the ones of glass fibers, but their main gain is the low cost. Plastic fibers are, compared to the glas

  by www.fiber-mart.com The electrical circuitry of the SFP transceiver modules is connected to copper or optical network. This type of transceivers is widely used for both data communications and telecommunication applications. Any official standards organization does not regularize the fiber optic SFP. The construction and specifications of this form-factor are specified by an MSA (multisource agreement) between competing manufacturers. SFP transceivers are readily available in a diverse range of options.   Advantages of SFP Transceivers SFP Transceiver Module  can be considered as the improved version of GBIC, and it is also called mini-GBIC. However, it allows better port density as its physical attributes are much compact than the GBIC. These transceivers are designed to offer data rates of up to 5 gigabits per second and even higher. With SFP transceiver, the up-gradation and maintenance of fiber optic network become more convenient than it has been with soldered-in modules. A si

  Electrodes are the most essential consumable of fusion splicing machine. In general, after a period of use, it needs to be replaced. This is the basic maintenance of fusion splicing machine. Thus, users of fusion splicing machines should have the ability to judge when to replace electrodes and master the maintenance knowledge of replacing electrodes. This post will guide you how to judge when to replace the electrodes and explain the replacing steps by taking example of the latest Fujikura fusion splicing machine FSM-80S.   When to Replace Electrodes of Your Fusion Splicing Machine What’s the best time to replace the electrodes of your fusion splicing machine, and how do you know when to replace it? Different users have different methods according to their working experiences. But the most basic method to judge when to replace the electrodes will be introduced here. Generally, there are two basic ways to judge whether the fusion splicing machine needs to be replaced its electrodes. T

  There are many fiber tools available for testing at different stages of the network, to meet various test requirements. These tests are used to reveal the total loss, optical return loss (ORL) and fiber length, can be in a single fiber or a complete network. In addition, the test may require further examination of the different elements of the measured link. Whether identify the characteristics of each component in the link, locate potential problems for a fiber, or find fault in the network, all will inevitably have to use optical time domain reflectometer (OTDR) – from commissioning to the optical network troubleshooting and maintenance, OTDR is the ideal choice. This article will describe the basic principles of an otdr test, for you better understanding the instrument specifications. What Is An OTDR? OTDR shows the link condition by reading the light level sent back from the optical pulse. Note that there are two types of reflected light: a continuous low-level light produced by
