Telecom services are shifting to a cloud infrastructure in which new services can be rapidly provisioned by deploying virtual network functions (VNFs) instead of physical boxes. This dramatically reduces the operating cost of carrier networks and allows carriers to invest in new infrastructure as revenue grows. The challenge in deploying telecom cloud services is to […]

Choosing the right backhaul for small operators
There is a near universal consensus among mobile operators that small cells are the way of the future – the only solution that will enable them to provide the capacity they need to meet the expectations for the fast growing numbers of smartphone users. Small cells allow operators to use their existing and new spectrum […]
Fluke Networks 3×3 802.11ac portable analysis tool
Fluke Networks has announced a new version of the AirMagnet WiFi Analyzer PRO offering new 802.11ac features to help organizations troubleshoot migration or co-existence path to the new 802.11ac technology and solve any 802.11ac problems in the network. With new toolkits, and the industry’s only 3×3 portable capture and analysis capability, businesses can now troubleshoot 802.11ac […]
Fiber-Optic Components: Harsh-environment optical fiber coatings: Beauty is only skin deep
For most people, optical fibers are made “special” by what is inside them—the complex optical structures that enable them to preserve polarization in sensors, harness high levels of pump energy in fiber lasers, or even the advanced core chemistries that make them resistant to hydrogen downhole, photo-darkening, or ionizing radiation. But the increasing deployment of […]
Applied Optoelectronics Reports First Quarter 2015 Results
“Although first quarter revenue was below our initial expectations as a result of the previously announced 40G supply shortages, we delivered 22 percent year over year growth and maintained gross margin above 33 percent,” said Dr. Thompson Lin, Applied Optoelectronics Inc. (AOI) founder and CEO. “With steady shipments of 40G components from our external supplier […]
Beyond the Triple Play
More than a decade ago, cable companies introduced the triple play of voice, video and data that is now the standard telecom offering worldwide. Fiber’s greater bandwidth and reliability allow FTTH providers to think beyond the triple play and offer services tailored to communities’ needs. Some of these services help differentiate fiber-to-the-home communities; some generate […]
Measuring Bandwidth of 10G Laser-optimized Multimode Fiber
1. The traditional Overfilled Launch (OFL) method of measuring bandwidth in multimode fiber has been replaced by new, more advanced techniques. The advent of 850 nm VCSEL light sources and 10G laser-optimized 50 µm multimode (OM3) fiber has enabled cost-effective 10G transmission for short reach enterprise applications. Unlike LEDs, VCSELs don’t light up the entire […]
IoT to deliver $1.9 trillion boost for logistics industry, says DHL and Cisco
The IoT will deliver a US$1.9tn boost to supply chain and logistics operations, according to a report by DHL and Cisco. And it estimates that $8tn will be generated through new connections over next decade. DHL and Cisco jointly released the trend report at the DHL Global Technology Conference in Dubai this month. DHL and […]
CONNECTOR TERMINATION TECHNOLOGY CHOICES
There are four basic classifications of fiber termination: no-epoxy/no-polish, no-epoxy/polish, epoxy/polish and pigtail splicing. No-epoxy/no-polish connectors No-epoxy/no-polish connectors offer the easiest and quickest termination technology available. Installers only need to strip, cleave, and lock the fiber into the connector body, which also contains a short pre-polished fiber stub in the ferrule. In effect, this is […]
The differences between SDH and SONET
SDH stands for synchronous digital hierarchy. SDH is the synchronous technology used everywhere except the US, Canada and Japan. Development of this international counterpart to SONET began a few years after SONET. The differences between SONET and SDH are based primarily on the different asynchronous bit rates that must be mapped into them. In developing […]
