OIF to tackle metro 100G, new gearbox, chip-to-chip communications
The Optical Internetworking Forum (OIF) launched three new projects at its third-quarter meeting last week. The projects will investigate extending the organization’s work in long-haul 100-Gbps DWDM to intermediate-reach application such as the metro, create the second generation of its Multi-Link Gearbox specifications, and look at optical engines for chip-to-chip communications.
Metro applications of 100-Gbps have become an area of interest for carriers and vendors alike. However, it also has threatened to become fragmented, as some vendors have touted coherent-based approaches similar to that specified within the OIF’s 100G DWDM work, while others have pursued direct-detect methods based on 4x28-Gbps technology (see, for example, "ADVA Optical Networking offers cost-reduced 100-Gbps for metro networks" and "ECI Telecom targets metro 100-Gbps via 4x28G with MultiPhy"). As the OIF’s long-haul work created an industry consensus around a single modulation format – dual-polarization quadrature phase-shift keying (DP-QPSK) with coherent detection – that the industry lacked at 40 Gbps, stepping into an increasingly bifurcated intermediate-reach applications space would appear to be a natural move.However, it is too early to tell whether the group working on this project will merely attempt to drive consensus around a lower-cost, streamlined version of coherent-enabled DP-QPSK or bring non-coherent 100G approaches within the OIF umbrella, according to spokesman Dave Stauffer, chair of the OIF’s Physical and Link Layer (PLL) Working Group. The project members likely will begin to examine this aspect at the OIF’s next quarterly meeting, October 16-18 in Hawaii, he told Lightwave.Stauffer’s PLL Working Group will have its hands full at that meeting with the other two projects. The Multi-Link Gearbox 2.0 project will build on version 1.0 of the specifications, with a particular emphasis on the aggregation challenges of marrying board-level interfaces designed to support the IEEE’s 40- and 100-Gigabit Ethernet multi-lane approach with the generally higher-speed interface requirements of optical modules. Stauffer hopes that this project will establish a path that can be followed when transmission rates exceed 100 Gbps in the future.
Verizon: 4G/LTE in more than 400 markets by year end
Verizon Wireless says it’s on track to serve more than 400 markets with its 4G/LTE technology. The service provider made the assertion as it revealed that starting July 19, its 4G/LTE network will become available in 33 new markets and expanded in 32 other markets.The new market launches will bring the total number of markets covered by Verizon Wireless to 337."Our rollout of Verizon Wireless 4G LTE in the United States is on track and we are confident we will meet our target of providing 4G LTE to our customers in more than 400 markets by the end of the year," said Nicola Palmer, Verizon Wireless CTO. "With more markets than all other U.S. wireless providers combined, our customers are the first to learn of the great advantages of the Verizon Wireless 4G LTE network for streaming video, downloading files, uploading pictures, and so much more, at consistently reliable fast data speeds."The 33 new markets are El Dorado/Magnolia and Russellville, Ark.; New London County, Conn.; Fort Pierce/Vero Beach and Melbourne/Titusville, Fla.; Columbus and Rome, Ga.; Burley, Idaho; Mattoon, Ill.; Anderson and Muncie, Ind.; Manhattan/Junction City and McPherson, Kan.; Lafayette/New Iberia, La.; St. Joseph, Mo.; Bozeman/Livingston, Kalispell and Missoula, Mont.; Goldsboro/Kinston, Roanoke Rapids and Rocky Mount/Wilson, N.C.; Zanesville, Ohio; Meadville and Punxsutawney/DuBois/Clearfield, Pa.; Orangeburg, S.C.; Sherman/Denison, Texas; Cedar City and Logan, Utah; Rutland/Bennington, Vt.; Lynchburg and Winchester, Va.; Bellingham, Wash.; and Beckley, W.Va.The company will also expand its 4G LTE network in 32 markets: Mobile, Ala.; Los Angeles, San Diego and San Francisco, Calif.; Washington, D.C.; Fort Lauderdale, Miami and Sarasota/Bradenton, Fla.; Hilo, Honolulu and Kahului/Wailuku/Maui County, Hawaii; Blackfoot/Idaho Falls/Rexburg, Idaho; Peoria, Ill.; Indianapolis, Ind.; Wichita, Kan.; Baton Rouge, La.; Baltimore, Md.; Kansas City and Springfield, Mo.; Akron, Cleveland, Columbus and Toledo, Ohio; Allentown/Bethlehem, Harrisburg and Scranton/Wilkes Barre, Pa.; Columbia and Greenville/Spartanburg, S.C.; Provo/Orem and Salt Lake City/Ogden, Utah; Fredericksburg, Va.; and Seattle, Wash.In real-world, fully loaded network environments, 4G LTE users should see average data rates of 5 to 12 Mbps on the downlink and 2 to 5 Mbps on the uplink, Verizon asserts.
Infonetics: Latin America is cable broadband market to watch
While North America was the only CMTS and edge QAM market to show sequential growth in the first quarter of 2012, market research firm Infonetics Research suggests equipment vendors should keep their eyes on Latin America.“Latin America has become the most competitive and dynamic market for CMTS vendors, with market share fluctuating wildly from quarter to quarter,” notes Jeff Heynen, directing analyst for broadband access and video at Infonetics Research. “Motorola regained the lead in the CALA region this quarter by a comfortable margin, whereas last quarter, Cisco surged and led with over half the market. Meanwhile, ARRIS was number-one in Latin America a year ago, dropped to a close third for the rest of 2011, but then popped up to second in the first quarter of 2012.”Three major trends will ensure the Latin American CMTS market remains at a boil, according to Heynen:The cable companies are locked in major battles with incumbent telcos for subscribers CMTS vendors have reduced prices for their DOCSIS 3.0 line cards A surge in sustained bandwidth use is coming as Netflix and other over-the-top video providers enter the market.Looking at the global market’s performance as a whole for the first three months of the year, North American sales jumped 13%, according to the latest "CMTS and Edge QAM Hardware and Subscribers" market share and forecast report from Infonetics. The spending decline throughout the rest of the world is typical for the season, the report states. International operators often use the first quarter to absorb new capacity gained at the close of the previous year, Infonetics says.Nevertheless, global CMTS port shipments hit record levels in the quarter, reaching 412,000. This 28% jump from the year-ago quarter derived from MSOs’ continued purchases of downstream and upstream CMTS capacity to deliver DOCSIS 3.0 and unicast video services.Cisco benefited most from this trend and retained its worldwide CMTS revenue share lead with 55%. However, Motorola was the only CMTS vendor to see a revenue increase. Harmonic, thanks to its ongoing video on demand, linear broadcast, and SDV deployments with operators worldwide, held onto the top spot among edge QAM vendors.The quarterly CMTS and edge QAM report provides worldwide and regional vendor market share, market size, and forecasts for standard and wideband cable broadband subscribers; upstream and downstream CMTS revenue and ports; and edge QAM channels and revenue by application, including linear broadcast TV, video on demand and unicast video, switched digital video, and DOCSIS.
