In the past week, there have been several successful demonstrations of terabit super-channel transmission using ultra-narrow channel spacings, which can increase overall system capacity by an additional 50 per cent compared to today’s commercial systems. ADVA Optical Networking and T-Systems, the systems and services division of Deutsche Telekom, took part in the ‘Terabit Demonstrator’ project, […]
Big Data for Telcos: cutting OPEX, improving service quality – and deploying services faster
Big Data has won acclaim – and rightfully so – for helping marketers improve the efficiency of their campaigns, assisting doctors in making diagnoses, fighting fraud, detecting hacker attacks, and even predicting financial markets. While most of the attention has been on consumer applications, Big Data analytics and techniques can be applied to telecommunications and […]
Coarse WDM and its applications
Coarse WDM and its applications Coarse Wavelength Division Multiplexing (CWDM), a WDM technology, is characterized by wider channel spacing than Dense WDM (DWDM) as defined in ITU-T Rec. G.671. CWDM systems can realize cost-effective applications, through a combination of uncooled lasers, relaxed laser wavelength selection tolerances and wide passband filters. CWDM systems can be used […]
Технология PON
PON (Passive optical network) — технология пассивных оптических сетей. Одна из главных задач, стоящих перед современными телекоммуникационными сетями доступа – так называемая проблема «последней мили», предоставление как можно большей полосы пропускания индивидуальным и корпоративным абонентам при минимальных затратах. Суть технологии PON заключается в том, что между приемопередающим модулем центрального узла OLT (Optical line terminal) и […]
Технология CWDM
Технология CWDM доказала свою эффективность для решения задач уплотнения оптических несущих – WDM (Wavelength Division Multiplexing). Суть этой технологии заключается в том, что потоки данных, передаваемые по отдельным оптическим линиям, с помощью СWDM устройств (CWDM мультиплексоров) cоединяется в единый оптический сигнал, передаваемый по оптоволокну. На ответной стороне выполняется демультиплексирование (обратная операция). Ключевые преимущества CWDM: До […]
Ultrahigh density MPO/MTP cabling system in Data Center
As the data throughput increases, 40Gb/s and 100Gb/s are more commonplace and now become a trend and hotspot for data-center cabling system, plus the fact that MPO/MTP connector is the up-and-coming standard optical interface for 40G and 100G Ethernet network, so it is predicted that MPO/MTP will eventually replace the standards for fiber optics as […]
Telkom has reduced the price of its fibre-to-the-home services and Do bundles on DSL, with some bundles now 15% cheaper.
Telkom has reduced the pricing of its ADSL and fibre-to-the-home packages. The company said its broadband bundles are now up to 15% cheaper, which follows a recent reduction in pricing of its LTE and LTE-Advanced offerings. “The new Do Bundle prices start at R399 a month (reduced from R408 previously) for the Do Basic Bundle, […]
FTTH Roll Out – Operational Considerations
There are new operational realities in the highly competitive world of FTTH based communication services. This competition has implications for customer service and network expectations. Customers have little loyalty to services so customer interactions become high risk/reward opportunities for building loyalty. The ability to give a live answer with the correct information during a single […]
FTTH Rollout – First Things First
Management of the entire life cycle is our focus and there are at least three aspects of management that work together for success. Vision – what do I want to accomplish? Planning – how can I best accomplish it? Action – doing it Vision is a picture in the mind of the finished accomplishment. For […]
Nigerian telcos looking for post-election stability in northern states
Given its potential for further growth, Nigeria’s large and fast growing telecom markets continues to attract considerable foreign investment. Far reaching liberalisation has enabled hundreds of companies, operating under a unified licensing regime, to provide a full range of telecom and value-added services. Mobile and broadband services are being rolled out rapidly, backed by new […]
