Thanks to the advances made in fiber optical technologies, fiber solutions have been deployed in ever-increasing applications where high-speed and high-performance data transmission is needed. They outweigh the copper solutions in such aspects as higher bandwidth, longer distances and Electromagnetic interference (EMI) immunity. Transceivers, one of the key components required in such fiber connections for high networking performance, have experienced the never-ceasing industrial designs, from lower port density to higher, from the standard modules to the final hot-plable ones, to meet the ever more flexible networking infrastructure. There is a broad selection of hot-plable transceiver modules available for fiber networking use, and you may feel a little confused about how to select the correct transceivers for your networking transmission. In this article, I will illustrate different aspects of transceivers that need to be known before choosing a transceiver. Transceiver Basics ...

by Fiber-MART.COM In recent years, Fiber to the Home (FTTH) has started to be taken seriously by telecommunication companies around the world, and enabling technologies are being developed rapidly. There are two important types of systems that make FTTH broadband connections possible. These are active optical networks (AON) and passive optical networks (PON). By far the majority of FTTH deployments in planning and in deployment use a PON in order to save on fiber costs. PON has recently attracted much attentions due to its low cost and high performance. In this post, we are going to introduce the ABC of PON which mainly involves the basic components and related technology, including OLT, ONT, ONU and ODN.   First of all, it is necessary to have a brief introduction of PON. In contrast to AON, multiple customers are connected to a single transceiver by means of a branching tree of fibers and passive splitter/combiner units, operating entirely in the optical domain and without...

1G and 10G data rates are not adequate to meet the future needs of high-bandwidth appli- cations. The requirement for higher data rates is being driven by many factors. Switching and routing, virtualization, convergence and high-performance computing environments are examples of where these higher network speeds will be required within the data center environment. Additionally, Internet exchanges and service provider peering points and high-bandwidth applications, such as video-on-demand will drive the need for a migration from  10G to 40/100G interfaces . Bandwidth OM3 and  OM4 fibers  were selected as the only multimode fiber for 40/100G consideration. The fibers are optimized for 850 nm transmission and have a minimum 2000 MHz∙km and 4700 MHz∙km effective modal bandwidth (EMB), respectively. Two EMB measurement techniques are utilized today for the bandwidth measurement. The minimum effective modal bandwidth calculated (EMBc) method offers the most reliable and pr...

A fiber optic cable is a network cable that contains strands of glass fibers inside an insulated casing. They’re designed for high performance data networking and telecommunications. Fiber optic cable carry communication signals using pulses of light, faster than copper cabling which uses electricity. They are becoming the most significant communication media in data center. Then how much do you know about them? This post serves as a guide for beginners. Fiber Components The three basic elements of a  fiber optic cable  are the core, cladding and coating. Core is the light transmission area of the fiber, either glass or plastic. The larger the core, the more light that will be transmitted into the fiber. The function of the cladding is to provide a lower refractive index at the core interface, causing reflection within the core. Therefore the light waves can be transmitted through the fiber. Coatings are usually multi-layers of plastics applied to preserve fiber strengt...

http://www.fiber-mart.com/fiber-optic-transceivers-sfp-transceivers-c-1_2.html The tunable DWDM SFP+ is one kind of DWDM SFP+ transceivers. They both can be used in the DWDM system. In the market, tunable DWDM SFP+ transceivers are often between two and four times more expensive than DWDM SFP+ transceivers. Thus, many may think DWDM SFP+ transceivers are enough in the DWDM system and wonder why tunable DWDM SFP+ transceivers are also needed. This post will introduce what is tunable DWDM SFP+ transceiver and explain why they need to be used in DWDM systems in details.   What’s Tunable DWDM SFP+ Transceiver? Tunable SFP+ transceivers are a new technology that is in development for a few more years due to the limiting power specifications of the SFP+. They are only available in DWDM form because the CWDM grid is too wide. So a tunable SFP+ transceiver is also called tunable DWDM SFP+ transceiver.   The tunable DWDM SFP+ transceiver is equipped with an integrated...
