ADTRAN Adds Four-Degree ROADM

ADTRAN introduced a new four-degree, scalable, compact Reconfigurable Optical Add/Drop Multiplexer (mini-ROADM) system-on-a-blade enables greater flexibility for service providers to respond to shifts in traffic and capacity demands in their residential, business, wholesale and mobile backhaul networks. ADTRAN's Optical Networking Edge (ONE) blade solution integrates into its flagship Total Access 5000/5006 platform.

ADTRAN said the flexibility of the four-degree, gridless mini-ROADM design reduces complexity in the network compared to alternative ROADM architectures that typically require a multi-blade implementation and a separate service delivery platform. The mini-ROADM design also simplifies agile optical network deployments by uniquely integrating into a single card the typical distributed and over-sized ROADM sub-elements, such as the amplifiers required to adjust for optical losses. These new features allow service providers to rapidly respond to customer requirements in dynamic markets like residential broadband, carrier Ethernet and 4G backhaul.

In addition, ADTRAN has doubled the transmission capacity of its ONE portfolio for up to 88 wavelengths of 10 Gbps. Future upgrade to 100Gbps networking and services will also be supported.

"ADTRAN has been working closely with customers to deliver a solution that allows them to merge multi-service access, aggregation and packet optical transport for increased network flexibility and scalability,” said Mano Nachum, packet optical networking product line manager, ADTRAN’s Carrier Networks Division. "The new ONE capabilities allow service providers to take full advantage of the benefits of agile photonics in response to the ever growing traffic and capacity demands on their metro, middle-mile and access edge networks." 01-Aug-12

Telefónica Tests Automated, Multi-Layer Control Plane with Juniper/ADVA

 Telef√≥nica I+D has tested an automated multi-layer, packet/optical network using ADVA Optical Networking's FSP 3000 and Juniper Networks' MX Series 3D Universal Edge Routers.

The trial, which was conducted in northern Germany as part of the IST project ONE funded by the European Union, tested the use of ROADM technology, RAYcontrol GMPLS control plane software and multi-layer configuration mechanisms to enable multi-layer restoration and automated DWDM service provisioning between IP/MPLS routers.

The trial enabled Telefonica to verify the significant potential for reduced operational and capital expenditures while driving new levels of speed and efficiency. According to Telefonica I+D analysis, multi-layer restoration led to over 37% reductions in capital expenditures in IP/DWDM networks. In addition, mean time to repair can be extended by a factor of 20 while keeping 99.999% availability, which translates to significant reductions in operating costs. However, the biggest impact was seen in the provisioning of new services.

Telefonica discovered that new services could be activated in less than 50 seconds. Previously this could take hours and was both costly and time intensive.

“The network is undergoing a huge transformation,” commented Christoph Glingener, CTO at ADVA Optical Networking. “This trial perfectly underlines the opportunities available to service providers to balance customer demand for bandwidth while at the same driving increased profitability and new business opportunities. Network automation is critical to this process and Telefonica has shown just how simple and effective unified multi-layer operations can be.”

London Internet Exchange Builds SuperCore with Juniper PTX

The London Internet Exchange (LINX) has deployed Juniper Networks' PTX Series Packet Transport Switch to create a new "SuperCore" network at the heart of one of the world's largest Internet Exchanges. The deployment, which went live in May, will be the second phase of a project announced by LINX in October 2011 to create a new network designed to meet current and future levels of customer demand for online activity.

Telindus serves as integrator for the project.

LINX’s 10 Points of Presence (PoPs) across London are connected by Juniper Networks MX Series 3D Universal Edge Routers, the first phase of LINX’s new network deployment which went live in late 2011. Both the PTX Series and MX Series run on Juniper’s Junos operating system.
LINX interconnects over 400 networks, including service providers and content owners from 50 countries, providing data, video and voice connectivity to hundreds of millions of customers using mobile and fixed connections. LINX’s infrastructure provides connectivity for high-profile events streamed online, including the Queen’s Diamond Jubilee, The Euro 2012 soccer championships, The Wimbledon Championships, and The London 2012 Olympic and Paralympic Games, in addition to everyday rich content upload and download demand.
  • In June, Verizon confirmed plans to deploy the Juniper Networks' PTX Series packet transport switches in major markets in the U.S. and Europe by the end of this year. Financial terms were not disclosed. The deployment marked the first major announced customer for the new packet transport platform. The companies cited an initial capacity of eight terabits per second for the high-density MPLS platform, which underpins an upgrade of the Verizon global IP backbone to 100G Ethernet, supports customer access speeds of 10G and above and enables growth for FiOS, wireless and cloud services.

Fujitsu Releases 100G Packet ONP

Fujitsu introduced a packet optical networking platform (Packet ONP) that employs the latest digital coherent technology with DP-QPSK optical modulation to enable ultrafast optical transmission speeds of 100Gbps x 80W over long distances. The Packet ONP platform employs a modular architecture that enables flexible assembly of WDM and packet transmission. It also features high-speed switchover to back-up lines in under 50ms in the event of network failure. A mesh network also makes trouble isolation possible with Colorless/Directionless/Contentionless (CDC) functionality, which allows for discretionary selection to channel through up to eight circuit routes. Fujitsu is supporting MPLS-TP with this platform.

Fujitsu has previously conducted 100G field trials at transmission speed of 100Gbps in North America. The company said these technologies will strengthen its FLASHWAVE 9500 multiplexed optical transport platform which is widely deployed in the global market. Moving forward, Fujitsu will make available its Packet ONP, integrated with WDM technology for optical transmission, to the domestic Japan and overseas markets.

ECI Converges Layers 0-3 with Apollo OMLT

ECI Telecom is taking the next step beyond packet-optical transport system (P-OTS) with a new modular platform that integrates L0 to L3 functionality with a single management system for all layers.

The Apollo Optimized Multi-Layer Transport system (OMLT) addresses metro core and regional networks for carriers shifting from traditional ring-based architecture to mesh-based and OTN switching architecture. With the OMLT, ECI's aim is to address shortcomings of packet-optical transport system (P-OTS), especially the need to deploy additional Carrier Ethernet platforms with separate management systems to support advanced data services.

ECI said its OMLT reduces infrastructure costs by optimizing the whole (multi-layered) architecture instead of the individual parts (layers), while simplifying the provisioning of new wavelength, private line, L2 or L3 services. The OMLT features a Universal fabric supporting OTN, Ethernet and switching between the two. The control plane uses GMPLS across the data (MPLS-TP) and optical layers.

The Apollo product launch includes six platforms:

Apollo OPT9603 – A compact OMLT system for metro access. It provides cost-effective aggregation of TDM and Ethernet/MPLS over OTN and WDM.

Apollo OPT9604 – Metro-edge OMLT that provides cost-effective aggregation of TDM, Ethernet and IP/MPLS over OTN and WDM. It can be configured as a pure optical networking platform (with OTN, ROADM and high-capacity WDM capabilities), a CESR with 50Gbps packet switching capacity, or an integrated packet-optical solution.

Apollo OPT9608 – Metro-edge OMLT that provides cost-effective aggregation of TDM, Ethernet and IP/MPLS over OTN and WDM. It can be configured as a pure optical networking platform (with OTN, ROADM and high-capacity WDM capabilities), a CESR with 100Gbps packet switching capacity, or an integrated packet-optical solution.

Apollo OPT9624 – OMLT for the metro, metro core and long-haul portions of the network. It provides cost-effective aggregation of TDM, Ethernet and IP/MPLS over OTN and WDM. It can be configured as a pure optical networking platform (with OTN, ROADM and high-capacity WDM capabilities), a multi-terabit ODU cross-connect with full WDM capability, a CESR with 100Gbps and multi-terabit packet switching capacity, or an integrated packet-optical solution.

Fujitsu: Ethernet Tag Switching Achieves 32% Percent Lower OpEx Than MPLS-TP

Fujitsu's implementation of Connection-Oriented Ethernet (COE), called Ethernet Tag Switching, reduces service providers' annual operating expenses by 32 percent over five years when compared to an MPLS-TP implementation, according to a research report by Network Strategy Partners (now part of ACG Research) cited by the company.

Fujitsu said its Connection-Oriented Ethernet enables a single metro network infrastructure with all the flexibility and cost benefits associated with Ethernet, while providing the performance, quality-of-service and security previously only available via SONET/SDH.

The study by Network Strategy Partners calculated the impact of using Ethernet Tag Switching, and then MPLS-TP, across six categories of service provider operations: OSS System Integration and Software Expenses, Network Management Equipment and Software, Training, Testing and Certification Operations, Network Care and Network Upgrades and Patches. In each category, Fujitsu Ethernet Tag Switching resulted in greater cost savings versus MPLS-TP.

"We found that the Fujitsu Ethernet Tag Switching implementation of COE produces lower OpEx than the MPLS-TP implementation of COE when service providers migrate from a SONET-centric to a packet-centric transport network infrastructure," said Michael Kennedy, Ph.D., principal analyst for ACG Research. "In particular, Ethernet Tag Switching goes a long way toward simplifying Operations, Administration and Maintenance (OAM) while incorporating widely-accepted Carrier Ethernet standards. The combination allows transport operations personnel to continue using the procedures and applications they've used for years, even as service delivery and transport functions become increasingly packet-based."
