May 15, 2016
Lightwave Staff
Fiber-optic network services provider Interoute says it has created a 2x100-Gbps fiber network connection for Sophia Connect. The route, which Interoute says it brought up in three weeks, will enable Sophia Connect to offer its wholesale customers connectivity from the Balkans, Caucasus region and the Middle East to western Internet hubs.
The fiber-optic network connection runs from Sofia, Bulgaria to Frankfurt, Germany through some of the major network hubs (including Budapest, Bratislava, Vienna, Prague and Munich) on Interoute's pan-European network (see "Interoute adds DTN-X to 100-Gbps pan-European fiber-optic network"). Interoute says it designed and packaged the connectivity for Sofia Connect within three days, then brought it into service in three weeks.
"We have worked with Interoute for four years and our relationship continues to flourish. Interoute consistently produces innovate services and is able to commit to deliver complex solutions over short lead times, which is exactly what we needed," said Yuliy Nushev, managing director and owner at Sofia Connect. "Speed and flexibility are vital for our operations and at all stages of the deployment we were confident that these commitments would be met." |

Tucked into Oclaro's third-quarter 2016 financials was an announcement that it plans to wind down production of its 40G line side products, signaling the end of the use of 40G technology in transport networks.
With 100G rapidly becoming the new standard in transport, the death of 40G was never in doubt; the only question was when. The answer looks as though it might be sometime in 2017.
Oclaro Inc. (Nasdaq: OCLR) had $11.5 million in revenue for 40G transport products in Q3, down $5 million from the prior quarter. The company expects sales to drop by $3 million to $4 million each quarter going forward. Oclaro said demand for 10G product is going to remain stronger than the company had expected, but growth is coming from 100G products.
The company's 100G growth is being driven in part "by more 100G being deployed in packet optical networks, the move to single mode 100G in the data center and the emerging metro market," said Oclaro CEO Greg Dougherty in the company's conference call with analysts. The quote was taken from the transcript provided by Seeking Alpha.
"40G line side (transport) optical modules are 300-pin modules and are now very old designs," Heavy Reading analyst Simon Stanley said. "Most transport systems now have 100G interfaces so I am not surprised that Oclaro [is] stopping production of 40G modules."

To be clear, there is still substantial demand for 40G products in data centers, but "interest in 40G is already dropping off in the data center," Stanley said, noting that QSFP+ 40G interfaces are being replaced by QSFP28 100G interfaces in many implementations.
Data centers don't always need 100G everywhere, but 10G is increasingly insufficient. Some of the interest in 100G, then, is in the lower splits -- 25G and 50G -- that can be ganged to get to 100G. (See Google: Give Us Better Interconnect... Now)
Stanley said 25G is still being developed, but "25G SFP28 interfaces will be replacing 10G SFP+ in data centers and other applications."
The role of 50G is unclear at the moment, Stanley noted. "50G may be limited to specific implementations such as the Microsoft/Inphi 2x50G PAM4 DWDM QSFP28 transceiver announced at OFC. The IEEE has chosen 8x50G PAM4 for 2km and 10km 400GE ports." |

from Yahoo poster

Gen 4 pic to enter TM. Not 1.2/2.4Tb, as it sounds like it's overkill, but still gen 4 pics with coherent technology.
"On the metro side of the business, we will obviously incorporate this kind of technology. Not the 1.2/2.4Tb technology but still gen 4 technology into pics and coherents that will go into the transmode portfolio as well. That will be more traditional, I would say, and require some testing cycles"
When he says more traditional, he is referring to the fact that with DTN-X and CX adoption of new pics it will be high margin. Existing customers can just take out old pic and plug in new pic on same infrastructure. With transmode, they had no pics so new boxes will need to be purchased/new product entering market.
"We don't tend to be guys that announce things very far in advance, so you can imagine the components are very far along"
See my earlier posts. This product line is obviously already in testing, as Infinera always announces products with in-production testing results to back them up.
Re new technologies to be announced at insight infinera:
"You better believe we're gonna expand it across the entire portfolio and I think it will give us another technology lead across every vertical we play in."

Pics and coherent not going to be in transmode till mid 2017
They say it's not preventing sales right now but really not till PIC is in Transmode will it improve cost structure (not paying other vendors for components or coherent) for them to really expand TM to their existing customer base that represents a massive metro network.
On the bright side, existing customer base has been "pushing them to go into metro for a long period of time."
TM systems and board layouts were all designed for discrete components. They have to redesign their solutions - essentially, rebuilding TM products to incorporate PIC is not insignificant.
Expects Telia to go broader with TM metro in Europe and North America.
Very good traction for TM with Cable Co's |

17 May 2016 | Jason Mcgee-Abe
Nokia Bell Labs has claimed a “significant breakthrough” in the effort to meet surging data demand by demonstrating 10Gbps symmetrical data speeds over traditional cable access networks.
The firm states that its lab test delivered 10Gbps download and upload speeds over traditional Hybrid Fibre Coax (HFC) cable systems. Using a prototype technology called XG-CABLE, the test demonstrates how existing cable systems can be used, aiding operators to deliver enhanced symmetrical ultra-broadband access services to residential and business subscribers seeking greater upload speeds.
"The XG-CABLE proof of concept is a great example of our ongoing effort and commitment to provide the cable industry with the latest innovations and technology needed to effectively address the growing demand for gigabit services,” said Federico Guillén, president of fixed networks at Nokia.
“The proof of concept demonstrates that providing 10Gbps symmetrical services over HFC networks is a real possibility for operators; it is an important achievement that will define the future capabilities and ultra-broadband services cable providers are able to deliver."
Achieving 'symmetrical' services – where the network can simultaneously support 10Gbps data speeds for both uploading and downloading content – is a major breakthrough for the cable industry, said Nokia.
Nokia Bell Labs started to explore the feasibility of delivering symmetrical service over HFC cable plants in 2014, but now claims it has successfully demonstrated the concept is valid and achievable as the XG-CABLE test used point-to-point cable topologies to deliver 10Gbps symmetric data speeds over coaxial cable using 1.2GHz of spectrum.
By leveraging the XG-CABLE technology, operators can effectively use existing HFC cables over the last 200 meters to provide upstream speeds never before achievable due to the limited spectrum available. This will enable operators to more effectively bring ultra-broadband services to consumer locations that were not physically or economically viable unless fiber was brought all the way to the residence. XG-CABLE will also provide operators with greater agility in how they use and manage their spectrum.
Commenting on the announcement, Robert Howald, vice president, network architecture at Comcast Cable, said: "While it is still early in the development of full duplex, Nokia's XG Cable proof of concept shows that multi-Gigabit symmetrical speeds over HFC, as targeted in the CableLabs FDX initiative, are achievable.” |

May 16, 2016 | By Mike Dano
BOSTON -- The cable industry is working to embrace software defined networking (SDN) and network function virtualization (NFV), but the transition will require a significant amount of work.
"I'm seeing a lot of variety [among cable operators embracing SDN]. There's not a single path," said Chris Bastian, SVP and CTO of cable industry trade group SCTE, during a FierceTelecom event here on the sidelines of the INTX trade show. "It's a very different answer depending on who you're talking about."
But, according to research firm IHS Technology, the market for SDN is poised to take off. The firm today reported that the service provider SDN market -- including hardware, software and services -- will grow from $289 million in 2015 to fully $8.7 billion in 2020, figures that represent a compound annual growth rate of 98 percent.
"Carriers have defined the vision, goals and architectures and are progressing through use cases, proof-of-concept projects, field trials and a small but growing number of commercial deployments," the research firm noted in a release announcing its new SDN report. "The partially proven promise keeps the industry moving as fast as it can, but we are still early in this long-term, 10- to 15-year transformation of service provider networks."
IHS also said that software and outsourced services will comprise 46 percent of SDN revenue in 2020, and that SDN orchestration and controller software revenue is forecast to grow to over $1.8 billion in 2020.
"There are many ways you can approach" deploying SDN, noted Dan Pitt, executive director of the Open Networking Foundation.
Adam Saenger, VP of global product development and management for Level 3, said that moving to SDN and NFV also requires operators to re-evaluate their workforce. He noted that Level 3 has been using SDN technologies internally for five years, and externally with its customers for four years.
"This has been a journey," Saenger explained, adding that cable operators will need to "plan for that [workforce] shift."
In order to smooth the transition from legacy systems to software-defined systems, ONF's Pitt said the group has developed a certification program for network technicians to become familiar with SDN technologies and deployments. "Programmers are going to be needed," Pitt noted.
And, according to several executives, the cable industry's move to DOCSIS 3.1 network technology creates an opening for them to begin virtualizing parts of their network. "That's a trend the vendors are going in," SCTE's Bastian explained.
Ryan McCowan, product manager with vendor Adtran, agreed. DOCSIS 3.1 "is a place where it makes sense to virtualize."
Interestingly, Pitt said that the move to SDN will allow operators to deploy a range of new services to customers. Once such service he pointed to was "data border control," whereby operators will be able to limit the types of data that can pass over country borders. He said regulators in Europe are keen to implement such technology for cyber security.
