Sumitomo Electric Lightwave offers jacketed MPO splice-on connector
Sumitomo Electric Lightwave (SEL) has expanded its Lynx2 CustomFit Splice-On Connector product line with what the company asserts is the first jacketed MPO ribbon splice-on fiber-optic connector.The new Lynx2-MPO Ribbon Jacket splice-on connector is designed to address the migration from 10-Gbps to 40- and 100-Gbps data rates, applications which increasingly call for ribbon fiber-optic cables. The connectors bring real-time scalability, reduced installation times, and cost-efficiencies when installing such ribbon cables, SEL says.SEL adds that jacketed ribbon has emerged as the preferred choice to maintain fiber protection and tensile integrity in data center, enterprise, MDU and FTTx, and other applications where ribbon cable has become necessary. In the case of optical fiber ribbon trunk cables, furcation is used to provide the added fiber protection in patch panels, since the cables are often re-entered for network moves, adds, and changes, SEL advises. The Lynx2-MPO Ribbon Jacket 12-fiber splice-on connector facilitates connectivity of these jacketed ribbon cables and jumpers by enabling exact length cable builds and terminations to be performed on-site, according to SEL. This eliminates the shorts, excess slack, and logistic delays that SEL asserts are associated with factory pre-connectorized cable assemblies.As a small form factor connector, the new MPO splice-on connector reduces space requirements in racks, panels, pedestals, and hubs. The Lynx2–MPO Ribbon Jacket connector, like all Lynx2 connectors, offers support of full media types and polishes required for low loss in standard singlemode and 62.5µm, 50 µm, and 50 µm laser optimized gigabit multimode fiber types.
“As the company to have designed and introduced the industry’s very first MPO splice-on connector, we understand the importance of continuous innovation, ensuring that our customers have the latest and most advanced solutions that are vital for the success of their network,” comments Joshua Seawell, Sumitomo Electric Lightwave’s director of its Lightwave Network Products division.

Verizon deploys more coherent 100-Gbps fiber-optic network technology
Verizon (NYSE, NASDAQ: VZ) reveals that it deployed coherent 100-Gbps capabilities across 13,000 miles (20,921 km) of its U.S. network and 1616 miles (2600 km) of its European infrastructure this year.The U.S. Tier 1 service provider says it has targeted high-traffic routes for the deployments, including Atlanta to Tampa, Kansas City to Dallas, and Salt Lake City to Seattle in the U.S. The deployments used the same routers and coherent-enabled optical transport equipment as on the company's first 100G routes deployed in 2011 – which means Ciena and Juniper Networks are happy companies (see “Verizon offers U.S. 100-Gbps deployment details”). Those deployments included Chicago to New York, Los Angeles to Sacramento, and Minneapolis to Kansas City.In Europe, Verizon’s deployments focused on connections between London and Paris and London and Frankfurt. Combined with the previous Paris-to-Frankfurt deployment (see “Verizon to deploy 100 Gigabit Ethernet on Paris-to-Frankfurt route”), Verizon now has a 100-Gbps European ring of more than 2600 km. Ciena supplied the 100-Gbps technology for these deployments as well. Juniper Networks supplied the routers for the initial Paris-to-Frankfurt deployment, and therefore would have been well positioned to supply the routers for the new 100G deployments.In addition to expanding route capacity, the 100-Gbps technology also improves network performance and scalability as well as create a converged core network. The company announced its intention to create such a converged core earlier this year (see “Verizon begins backbone convergence”)."Expanding 100G technology on our high-performance U.S. and European networks means Verizon is able to successfully meet traffic demand while increasing efficiency and capacity," said Kyle Malady, senior vice president of global network operations and engineering for Verizon. "Increased video traffic, LTE 4G growth, and cloud usage are driving bandwidth demand, and 100G is critical to creating that rich end-user experience."

IEEE establishes IEEE 802.24 Smart Grid Technical Advisory Group
The IEEE has announced the formation of the IEEE 802.24 Smart Grid Technical Advisory Group (TAG). The newly formed collective will aid in addressing challenges related to the use of IEEE 802 standards in smart grid applications.IEEE 802.24 is a collaborative umbrella organization that will work with multiple IEEE 802 working groups (WGs) and will liaise with key stakeholders in the smart grid ecosystem, such as regulatory agencies, other standards development bodies, and industry organizations.“IEEE 802 networking standards have achieved near-ubiquitous adoption – they’re essential underlying technologies found in almost every computing device made today, whether it’s a desktop computer, laptop, tablet, or smartphone. These standards are an integral part of the connected world,” said Bill Ash, strategic program manager, IEEE Standards Association (IEEE-SA). “Now with the smart grid’s continued evolution, IEEE 802 standards will also play a fundamental role in critical applications like home automation, advanced metering infrastructures, renewables integration, and demand response. The IEEE 802.24 Smart Grid TAG will serve as the ultimate resource for practical information and insight about the use of IEEE 802 standards in the smart grid.”Among the IEEE 802 WGs taking part in the new collective are the IEEE 802.1 Higher Layer LAN Protocols WG, IEEE 802.3 Ethernet WG, IEEE 802.11 Wireless LAN WG, IEEE 802.15 Wireless Personal Area Network (WPAN) WG, IEEE 802.16 Broadband Wireless Access WG, IEEE 802.18 Radio Regulatory TAG, IEEE 802.21 Media Independent Handoff WG, and IEEE 802.22 Wireless Regional Area Networks (WRAN) WG.Primary responsibilities and activities falling under the IEEE 802.24 Smart Grid TAG’s purview include facilitating coordination and collaboration among IEEE 802 groups and providing conference and event speakers able to address the use of IEEE 802 standards in smart grid applications. Participants will cooperatively develop a range of materials such as white papers, guidelines and presentations.
