Cyan unveils single-slot 100-Gbps line card
Packet-optical transport specialist Cyan has released the DTM 100G, a single-slot 100-Gbps transponder for its Z-Series platforms. Besides its small size, the optical transponder also offers significant flexibility through its ability to accept a variety of CFPs, thus accommodating multiple reaches and traffic types. At least one non-U.S. Tier 1 carrier appears interested in the technology, according to company sources.Cyan designed the DTM-100G using off-the-shelf components, including a transponder module based on dual-polarization quadrature phase-shift keying (DP-QPSK) with coherent detection, revealed CMO and Vice President of North American Sales Eric Clelland and Vice President Product Development Scott Pradels. Despite the company’s current focus on metro and regional applications for 100G, Cyan currently doesn’t have plans to come up with a 4x25G version of the transponder, Pradel said.The unit is designed to accept a wide variety of client-side CFP optical transceivers, including SR10 (100 m), LR10 (2 km), LR4 (10 km), and ER4 (40 km) modules. It also features a DWDM interface that is fully C-Band tunable. In addition to 100-Gbps optical transport, the card also will support 100 Gigabit Ethernet and G.709 Optical Transport Network (OTN) OTU4 regeneration.The DTM-100G also operates under Cyan’s Blue Planet software-defined network (SDN) umbrella (see “Cyan offers Blue Planet OpenFlow-based SDN capabilities”), which Clelland said makes the card among the first SDN-compatible 100-Gbps technologies.The line card has already reached the field, with Great Plains Communications among the first customers.“The flexibility and form factor of the DTM-100G are perfect for our network,” said John Greene, chief network engineer at Great Plains Communications, via a Cyan press release. “As we build out our network, we typically do not know how far our customers will be from our points of presence, and the optical reach flexibility inherent in the DTM-100G means that we don’t have to.”Meanwhile, other carriers are putting the card through its paces. A Tier 1 carrier outside of the U.S. is an example; the carrier is not yet a Cyan customer, but Clelland expressed confidence the operator soon would be. Meanwhile, both Clelland and Pradels believe that, because of the card’s client-side flexibility, they will see some business from carriers interested in using the DTM-100 to generate 100-Gbps signals that would be carried by equipment from other vendors as alien wavelengths.
Prysmian intros RetractaNetxs retractable FTTH cable
Prysmian Group has introduced RetractaNetxs, a direct buried retractable fiber-optic cable. The new fiber cable is particularly well suited to fiber-to-the-home (FTTH) deployments, Prysmian says.RetractaNetxs features the company’s RetractaCable, which is filled with small fiber modules. These modules are designed to be cut at one point in the network and retracted to another, where they can be fed or blown through microducts directly to the customer premises. Thus, the system offers a retractable cable from the Optical Distribution Point splice closure to the customer premises.With RetractaNetxs, ducts can be installed at a depth of 30 cm instead of the normal 60 or 120 cm. This makes it possible to lay 600 m of fiber a day, limit public inconvenience, and significantly reduce carbon dioxide emissions, the company asserts.Prysmian says that several pilot projects using the new cabling technology are already underway with such service providers as Reggefiber, VolkerWessels Telecom, Jelcer Networks, Deutsche Glasfaser, and BAM. They include the deployment of a fiber-optic network in Noorderveld, Netherlands; a sewer-based fiber-optic broadband network in Lonneker, Netherlands; and a network deployed in the Bocholt Bario district, which Prysmian says is now being called “the fastest village in North Rhine-Westphalia.”“This solution makes rollouts faster, reduces pollution and cuts labor costs. It provides quick connections at a low total cost of ownership, through significant savings on labor and materials. Compared to traditional point-to-point network solutions, RetractaNetxs can reduce the overall cost of OSP network deployment by 7%-9%,” explains Edgar Aker, director Telecom Benelux, Prysmian Group. “RetractaNetxs is a prime example of our ‘Value Innovation’ concept, which essentially means we are rethinking technologies, in order to come up with instantly applicable solutions for real challenges that our clients face.”
Infonetics sees 2013 growth in optical hardware sales
Sales of optical transport gear dropped 10% in 2012 versus 2011, according to market research firm Infonetics Research. But disappointed equipment vendors should take heart: 2013 will be a better year, says an Infonetics analyst.“After ending 2012 on a flat note, things are looking up for the optical market in 2013,” offers Andrew Schmitt, principal analyst for optical at Infonetics. “Our conversations with equipment providers continue to trend positive, particularly in North America where 100G spending is about to ramp. The general consensus remains that an optical cycle for equipment in the core is emerging, what we call the ‘optical reboot.’“Meanwhile, there are positive rumbles in the EMEA region, where 2012 ended with a spending flourish and carriers are cutting dividends to plow capital into general capex,” Schmitt adds. “And we are looking forward to our visits with carriers in Beijing this spring to get a good read on the year, but the preliminary indication is it will be a huge year for 100G. China is about half of the global 40G WDM market, and 2013 will be the peak year for 40G worldwide.”The positive outlook is no doubt welcome after the trials of 2012, which was capped by a good news/bad news fourth quarter. According to Infonetics Research’s upcoming Optical Network Hardware report (available February 27), the fourth quarter saw sales 2% greater than the previous quarter. However, that figure was still down 13% from the same quarter in 2011.Similar sentiments could be expressed about some of the optical network equipment vendors as well. For example, Alcatel-Lucent bounced back from its worst-ever results in the third quarter to see sales rise 29% sequentially, thanks to a boomlet in spending from the EMEA region. However, like the overall performance of the market during 4Q12, revenues from the company’s WDM product line still weren’t as high as they were in 4Q11.Meanwhile, as Dell’Oro Group recently noted (see “Optical hardware sales shrank in 2012, confirms Dell'Oro”), sales of SONET/SDH equipment tanked in 2012, dropping 30%.Infonetics’ quarterly Optical Network Hardware report offers estimates of worldwide and regional market size, market share, analysis, forecasts, and trends for metro and long haul SONET/SDH and WDM equipment, Ethernet optical ports, SONET/SDH/POS ports, and WDM ports.
