ECI Telecom emphasizes Layer 3 capabilities in next-generation packet-optical transport systems
ECI Telecom today has unveiled the Apollo family of Optimized Multi-Layer Transport (OMLT) systems that the company describes as the next generation of packet-optical transport platforms. The company cites the line’s support of Layer 3 functions and its ability to tightly integrate multiple network layers under a single network management system as chief points of differentiation.According to Rafael Francis, head of technology and marketing, Americas, at ECI, current packet-optical transport systems fall short in three areas:True convergence of Layer 1, 2, and 3 functionality, which requires the use of Carrier Ethernet platforms to support advanced data services.Reliance on multiple network management systems to manage operations at these different layers.Lack of configuration flexibility.The Apollo OMLT platforms address each of these concerns, Francis asserted in a meeting with Lightwave last week. Key enablers include a universal switch fabric that supports Ethernet and Optical Transport Network (OTN) requirements, including interworking between the two traffic types, as well as support of IP/MPLS and MPLS-TP where network demands require it. The systems also feature colorless, directionless, and contentionless ROADMs in 2-degree and greater formats, Francis said.The family includes:Apollo OPT9603 – A metro access platform for aggregation of TDM and Ethernet/MPLS over OTN and WDM.Apollo OPT9604 – A metro-edge OMLT for aggregation of TDM, Ethernet, and IP/MPLS over OTN and WDM. It also can be configured to act as a pure optical networking platform with OTN, ROADM, and WDM capabilities or a Carrier Ethernet switch router with 50-Gbps of packet switching capacity as well as an integrated packet-optical transport system.Apollo OPT9608 – Another metro-edge OMLT focused on aggregation of TDM, Ethernet and IP/MPLS over OTN and WDM, but with 100 Gbps of packet switching capacity. Like the OPT9604, it also may serve as an optical networking system or Carrier Ethernet switch router.Apollo OPT9624 –This OMLT targets metro, metro core, and long-haul applications. It is designed to provide aggregation of TDM, Ethernet, and IP/MPLS over OTN and WDM. It also can be used as a pure-play optical networking platform, a multi-terabit ODU crossconnect with WDM capability, or Carrier Ethernet switch router with 100-Gbps and multi-terabit packet switching capacity. As its name implies, it supports 24 universal I/O slots.Apollo OPT9648 – The Cadillac of the Apollo line, this is a 48-slot version of the OPT9624.Other elements of the line include the Artemis 1P/2P passive optical platforms, and LightSoft unified network management system. ECI also will offer its suite of 1Net consultancy, planning, and network design services.The Apollo line will support 40-Gbps transmission rates initially, with 100-Gbps capabilities available in the latter part of 2012, Francis said. The OPT9603 and OPT9608 (an enhanced version of ECI’s existing 9608 Carrier Ethernet switch router) are the first members of the family to be made available. ECI will release the OPT9624 early in 2012, with the OPT9648 following in the later half of the year, Frances says.

Hibernia Atlantic plots transatlantic 100G course after trials with Huawei
Transatlantic fiber-optic network services supplier Hibernia Atlantic says it plans to deploy 100-Gbps technology on several legs of its network after successful trails of the technology. Having run technology from Huawei through its paces, with help from Huawei Marine, Hibernia Atlantic will deploy 100-Gbps between Halifax and Montreal and between Amsterdam and London by the first quarter of next year, with other deployments to follow.“Additional capacity to our existing network system will provide the ability to meet the growing service needs of our clients,” said Bjarni Thorvardarson, CEO for Hibernia Atlantic, in a press release. “The carrier, multimedia, and enterprise industries all require high capacity at the 100-Gbps level to ensure high-performance data transmissions. In addition, we are deploying Project Express, the first transatlantic, fiber-optic cable with the shortest latency in history at sub-60 milliseconds roundtrip. With this innovative cable link, as well as our existing, diverse cable assets, our clients will now be able to access secure and diverse connectivity at the highest-performance capacity currently available.” The trial, which Huawei Technologies (USA) Vice President – Optical Network Marketing and Product Management Reg Wilcox told Lightwave occurred within the past month, tested 100-Gbps transmission between Halifax, Nova Scotia and Southport, England, a distance greater than 5,000 km. The demonstration, which Huawei asserts is the 100G test across the Atlantic, included transmission alongside 40-Gbps at 50-GHz spacing. It also demonstrated co-propagation of 100 Gbps at 50-GHz spacing.The 100-Gbps technology, currently available on Huawei’s OptiX platforms, conforms to the OIF’s specifications, including use of dual-polarization quadrature phase-shift keying (DP-QPSK) with coherent detection. It also benefits from the company’s digital signal processing (DSP) algorithms and forward error correction (FEC) technology.The 40-Gbps signals involved in the trial used Huawei’s Enhanced DQPSK modulation format. Wilcox says that coherent 40-Gbps technology is coming to market as well.

Infinera, TeliaSonera complete terabit field trial
Infinera Corp. (NASDAQ: INFN) and TeliaSonera International Carrier say they have successfully completed the world’s first terabit optical transmission based on 500-Gbps superchannels. The field trial covered a total distance of 1,105 km using a route between Los Angeles and San Jose.Like every announcement of a field trial, this one contained enough qualifiers so that the company involved can claim a first. Infinera is not first to demonstrate terabit transmission, nor is it first to demonstrate superchannels – a large unit of optical capacity created by combining multiple optical carriers into a single managed entity. What’s significant in this instance is that Infinera has demonstrated not one but two superchannels based on its 500G photonic integrated circuit (PIC) technology in a situation that closely mimics the real world using pre-production equipment over installed fiber that is carrying other traffic. “Every time we do one of these field trials, there is a specific goal,” explains Geoff Bennett, director of solutions and technology at Infinera. “Because it costs a fair amount to do, the team has to demonstrate significant progress.”Infinera had previously demonstrated a single 500G superchannel. Now it has scaled up to two superchannels by using pre-production boards from the DTN-X, the next-generation packet-optical platform that it unveiled in September (see “Infinera debuts DTN-X packet-optical transport platform with 500G PIC, OTN/MPLS support”).Most field trials are still an experiment and vendors don’t have enough resources to build the equipment for more than one superchannel. Typically such experiments occupy multiple racks of equipment because they have to be built from discrete components. However, in Infinera’s case all they needed was two briefcase-sized line cards. “The big difference is that we’ve got enough kit to demonstrate more than one superchannel,” Bennett added. “We’re using pre-production equipment; stuff that’s going to start early shipping next year.”Another important aspect of the field trial, he says, was that the fiber was carrying 300 Gbps of existing traffic encoded with non-return-to-zero (NRZ) modulation. In the past, people were worried that it wouldn’t be possible to mix coherent and non-coherent channels on the same optical fiber because of non-linear interactions between the different signals; this demonstration shows that vendors can manage the interaction.Another high-profile demonstration of terabit transmission was described in a post-deadline paper at OFC/NFOEC earlier this year. Verizon and NEC transmitted 100 Gbps, 450 Gbps, and 1 Tbps superchannels simultaneously over a long-haul fiber link in the Dallas area (see “Verizon, NEC tout high-speed optical network trials”).TeliaSonera has been using Infinera’s DTN system equipment on its US network since 2009, so it makes sense that it’s kicking the tires of the upcoming product, the DTN-X (see “TeliaSonera taps Infinera for US network”).
