Next-Generation PON will Support at Least 40 Gbps Downstream

By admin, July 18, 2012 8:50 pm

What the next generation of fiber-to-the-premises networks will look like is becoming clear, now that members of the Full Service Access Network (FSAN) have reached an agreement on what they’re calling NG-PON2.

The agreement is not actually a standard, but instead outlines the direction that standards efforts will take, explained FSAN Chair Martin Carroll, who is also a distinguished member of the technical staff at Verizon?(News – Alert).

As FSAN considered the next generation of FTTP, various members proposed a wide range of approaches, including some that were “more elaborate and on the bleeding edge” and some that were “more current and readily available,” Carroll said.

Members ultimately settled on what they’re calling time and wavelength division multiplexing (TWDM) because the group believes that approach will meet target bandwidth and other requirements and can be developed relatively quickly. Standards could be ratified by as early as 2013 and products could be deployable by 2015, FSAN says.

Like today’s FTTP networks based on GPON, TWDM will rely on time division multiplexing but in addition will “use multiple wavelengths to stack TDM streams,” said Carroll.

The minimum bandwidth goal for an individual NG-PON2 is 40 Gbps downstream and 10 Gbps upstream, with total bandwidth shared among multiple subscribers. Noting that the current highest-speed PON, XG-PON, operates at 10 Gbps downstream, Carroll said the minimum target bandwidth levels should be easily reachable by using four wavelengths.

He added that systems with downstream bandwidth as great as 160 Gbps could be part of the standard, but he believes the 40 Gbps system will be considerably more cost effective.

The 40 Gbps requirement was driven by the per-customer bandwidth goal of 1 Gbps and apparently envisions each PON continuing to serve about 32 customers as with typical PONs deployed today. But bandwidth will not have to be allocated equally between all of the customers served from a single PON. Carroll believes network operators are likely to give residential customers service at rates below 1 Gbps, while business customer data rates will start around 1 Gbps.

Operators envision a wide range of use cases for NG-PON2, including support for mobile backhaul and potentially as a replacement for Sonet and SDH-based data services. Because NG-PON2 will use a point-to-multipoint approach, Carroll expects it to be more cost effective than point-to-point alternatives.

I asked Carroll whether the people creating the NG-PON2 standard would consider home run wiring – an approach that is gaining in popularity because some operators believe it is more future-proof than PON. Carroll said the emphasis is on PON, but he noted that the group also wants to have some wavelengths available for using WDM technology in more of a point-to-point configuration.

“It would be a PON architecture on the fiber side, but when you look at what the signal itself does, it would be more of a point-to-point allocation of the wavelength,” he said.

FSAN initially was primarily a North American organization dominated by the former RBOCs, but over the last decade it has become a much more global organization – and that reality has driven some of the requirements for NG-PON2. Carroll noted, for example, that NG-PON2 must co-exist not only with GPON, which has been widely deployed by Verizon, but also with XG-PON. The latter requirement was driven largely by China Telecom and China Unicom?(News – Alert), Carroll said.

FSAN expects to work through the International Telecommunications Union in creating the NG-PON2 standard – another example of the global nature of the technology. online casino .

Finisar Corporation Acquires RED-C Optical Networks

By admin, July 5, 2012 11:31 am

Finisar Corporation announced that it has signed an agreement to acquire the outstanding equity interests in RED-C?(News – Alert) Optical Networks, Inc. This will expand the portfolio of Finisar’s product lines for telecom applications by adding amplification technologies like Erbium Doped Fiber Amplification (EDFA), Raman amplification and dynamic Hybrid amplification.

In a release Eitan Gertel, Finisar’s CEO said, “RED-C has been an innovator in optical amplification, which we view as an increasingly critical technology as networks get faster and more complex.”

RED-C Optical is a Delaware- based corporation operating from Tel Aviv in Israel. RED-C’s amplification technologies are imperative for ROADM?(News – Alert) line cards and can extend the reach of transceivers and transponders. This will be particularly useful for 100 Gbps and 40 Gbps coherent transmission, ultra-long repeater-less links, and low latency networks, said officials.

?“As we have further penetrated the line card market with our differentiated WSS technology, we see this acquisition as a tremendous opportunity to further innovate for our customers and advance our vertical integration strategy,” Gertel added.

The demand for bandwidth has resulted in a major transition to coherent transmission and mesh topologies for optical networks. These are capable of delivering better resilience cost effectively but need advanced optical amplification technologies to optimize performance.

RED-C’s Hybrid amplifier products are equipped to offer better performance when compared to standalone EDFA and Raman optical amplifiers. They are based on RED-C’s core underlying IP and the RED-C’s Hybrid optical amplification platform and will soon replace standard EDFAs for next-generation LH and ULH optical networks. Further, greater opportunities are expected for the Hybrid Raman EDFA platform. I have no idea what the ingredients in my buy detox drink were meant to do (I have been on other detoxes before that did make me feel different / possibly even better) but this one didn’t do that..

“Finisar is pleased to be joining with RED-C to deliver this next wave of optical amplifier technology. We expect RED-C’s high performance EDFAs and Raman amplifiers, currently deployed in optical networks around the globe, to continue to deliver strong growth for the RED-C business,” said John Clark, Finisar’s EVP, Technology and Global R&D.

In related company news, Steve Frisken, CTO of Finisar Australia Finisar presented a paper on the topic “WSS and ROADM Architecture Advances and Evolution” at Telco Components World, co-located with the WDM & Next Generation Optical Conference which took place in June 2012. The presentation threw light on the fundamentals of wavelength switching technologies like Liquid Crystal on Silicon (LCoS), and Wavelength Selective Switches (WSS).

In March this year, Abovent’s boards of directors approved a definitive agreement to be acquired by Zayo Group?(News – Alert) for approximately $2.2 billion. Each share of AboveNet common stock issued and outstanding immediately prior to the transaction was entitled to get $84.00 per share in cash, which reflected a 13-percent premium over AboveNet’s closing price on March 16, 2012, and a 21-percent premium over the average closing stock price for the past 60 days.

Recently, Zayo Group announced that the company completed $3.34 billion in equity and debt financing in conjunction with the close of its previously announced acquisition of AboveNet. The company also refinanced all existing Zayo and AboveNet debt. Your Medicare Advantage Plan essentially replaces Original Medicare, meaning instead of Medicare paying it’s share of your claims Medicare pays the private buy-detox.com company and that company then pays it’s share of your claims as dictated by your plan..

Along with a $250-million revolving credit facility, which is undrawn, Zayo also closed on $2.87 billion of new debt in the form of a term loan and senior secured and unsecured notes. Zayo also closed on $2.87 billion of new debt financing plus a new $250-million revolving credit facility that remains undrawn, the company stated in a press release.

“Zayo welcomes our new equity and debt investors, as well as current investors who have provided continued support of our growing business,” said Ken desGarennes, CFO at Zayo Group. “We are pleased with the market reception to our recent fundraising effort, particularly given the uncertainty in the broader markets.”

Recently, TMC’s?(News – Alert) Brittany Walters-Bearden reported that the company announced plans to make its business even bigger for mobile than it has already been. The company has formed a core group to concentrate on small cell and Fiber to the Tower (FTT) technology. The group will report directly to the company president, Matt Erickson. This technology makes use of the small antennas that can be attached to lampposts, buildings, or existing poles to better help network reach for mobile network providers.

High Bandwidth Networks are Needed to Meet Increasing Demands

By admin, June 11, 2012 7:36 pm

As smartphones and an array of other type of next-generation devices are continually introduced to a corporate network, many infrastructures are folding under the pressure as they are not able to withstand the pressures associated with the newly added content.

As broadband usage will only be getting larger by the day, some of the major drivers for growth include the network being forced to expand geographically as building and data centers are being erected, causing consumers to require larger and larger pipes and wavelengths which is prompted by the media or more specifically cable companies, media providers and content providers.

Custom private networks are an ideal solution for a wide customer base, as they easily handle the volume of ever increasing video traffic.?Fiber-to-the tower and bandwidth to the tower needs are also being raised as both capacity and connectivity needs are growing alike.

Recently at The Cable Show 2012 which took place in Beantown, a.k.a. Boston, Mass, when asked about when she believes new content will demand more than 100G, Colleen Gallagher, vice president of business development, First Communications stated, “We are actually already working with some companies to provide them with something called alien wavelength, where you are not limited by that first 10 or first 100G—so the technology is there to address that if anyone has that kind of need.”

This “alien wavelength” is also proving highly valuable for people who are not looking for huge amounts of bandwidth but want to have finite control over their bandwidth including financial companies who are completing high transaction trading who are looking to have a high level of security over that network. In essence, its one step away from owning and lighting your own fiber network but another company is powering that network for them.

Gallagher added, “They like the idea of not having to come back to a service provider and having another cost to light the next circuit. So, they invest in a different kind of a platform with us and then they can even have us be the provisioning arm for them if they don’t want to do it internally but know it is there when they need it.”
