Types of Fiber An optical fiber transmits light through a flexible, transparent strand of pure glass not much wider than a human hair. It functions as a waveguide, or “light pipe,” to direct the light. On a cell tower, an optical transceiver module inside the towermounted radio converts the optical signal into electrical signals for […]
While a number of different system designs have been deployed, FTTA cabling architectures generally consist of a smaller base band unit (BBU) at the bottom of the tower and multiple fiber-fed remote radio units (RRUs) at the top of the tower. Fiber cables replace coaxial feeders running up the tower in order to support advanced technologies such […]
Not all FTTH networks are built the same. Since construction and outside plant account for the majority of total network costs, getting the architecture right has a major impact on the business case. The network architecture can also impact time-to-market, labor/training requirements, future upgradeability, network performance, and ultimately customer satisfaction. This paper provides an overview […]
The Vodafone Group has started rolling out fibre to the home (FTTH) programmes in Ireland and Portugal as part of a €600 million network expansion programme. Ireland will be the first country in Europe to deliver the end to end fibre through its electricity infrastructure nationwide. As part of SIRO, a joint venture in Ireland […]
There are five things you should know before your next installation in order to avoid potential network failure and reduce your risk of costly mistakes. 1 Know your contractor 2 Increase error-free work with trained technicians 3 Ensure a quality installation with quality fiber optic products 4 Require a 25-year warranty for additional network protection […]
The connectors and adapters are coded throughout to ensure the correct orientation of the plug connection. The three polarity methods A, B and C as defined in TIA-568-C, for their part, are used to guarantee the right bi-directional allocation. This chapter describes these methods briefly. Method A Method A uses straight-through type A backbones (pin1 […]
What is MPO connectors: structure and function The MPO connector (known as multi-fiber push-on and also as multi-path push-on) is a multi-fiber connector defined according to IEC 61754-7 and TIA/EIA 604-5 that can accommodate up to 72 fibers in the tiniest of spaces, comparable to an RJ45 connector. MPO connectors are most commonly used for […]
Sales of 10-, 40-, and 100-Gbps optical transceivers for datacom applications grew 14% year over year in the first half of 2015, says IHS (NYSE: IHS). Growing interest in 40G QSFP and 100G CFP/CFP2 helped spur datacom optical module sales to $752 million in that timeframe, according to the most recent «IHS Infonetics 10G/40G/100G Data […]
ACG Research expects the global market for optical data center interconnect (DCI) technology will increase from just over $1.1 billion in 2014 to $4.7 billion in 2019, a compound annual growth rate (CAGR) of 44.9%. «Uptake of optical DCI is being driven by the migration of services to data centers and the cloud as service […]
On a data transmission network, one of the main cause for insertion loss on a fiber link is macro bending. This is commonly caused by tight installation or handling. As Fiber-to-the-Home (FTTH) networks lead to a significant increase of fiber installation in the last mile, even G657 fiber are used. the space constraints become increasingly […]
