At ECOC last week, France Telecom spoke publicly about its participation in the EU's SARDANA research initiative and the cost savings it hopes to achieve with the resultant technology. The carrier plans to evaluate SARDANA's WDM-PON during a trial in the town of Lannion, France in 2010.

지난주 ECOC에서 프랑스 텔레콤이 유럽연합의 SARDANA 연구 시작에 참여했다고 발표. 프랑스의 Lannion 시에서 SARDANA's WDM-PON 개시.

SARDANA stands for "Scalable Advance Ring-based passive Dense Access Network Architecture." As the name implies, the goal of the three-year program is to develop a ring-based WDM-PON architecture with a reach of around 100 km.

The EU has also funded a WDM-PON initiative known as GigaWaM, championed by the likes of Ignis Photonyx (See "EU to fund Ignis-led WDM-PON project.")

And I couldn't help but notice that the first publicly announced customer for LG-Nortel's WDM-PON-based Ethernet Access system is a Dutch broadband service provider (See "UNET deploys Nortel's WDM-PON based system.")

All of which makes me wonder: Is WDM-PON better suited to the European marketplace? Or are the Europeans simply going to be the early adopters of the technology, much like Japan led the way with its early deployments of PON technology?

그래서 궁금하다. WDM-PON이 유럽에서 더 좋나? 혹은 유럽이 얼리 어답터가 되려고 하는건가? 마치 일본이 PON 기술의 전개에서 그러했듯이..

I recently interviewed Giovanni Manto, leader of Nortel's Ethernet Fiber Access Solutions Division, on the subject of WDM-PON. He noted that in North America, Verizon has settled on GPON, and in Asia, NTT has standardized on GE-PON. But in Europe, there is no such "900-lb. gorilla," as he called them.

최근 Giovanni manto (노텔) 을 WDM-PON 관련해서 인터뷰 했다.
걔가 "북아메리카에서는 버라이존이 GPON 깔아놓았고, 아시아에서는 NTT 가 GE-PON 표준화 해 놓았는데 유럽에서는 그런 고릴라가 아직 없다"고 말했다.

"A lot of the EMEA customers we deal with historically are in two camps right now," Manto told me. "One is basically saying, 'We want to build point-to-point networks. We believe point-to-point networks are scalable networks, they are foundational, and we can change the personality of that particular fiber connection depending on what our customers want.' Some of them have actually stipulated publicly that GPON will never be deployed in their network because of all the encumbrances and issues that GPON brings to their network, specifically from an operations standpoint and from a scalability standpoint."

어떤 커스터머들은 GPON 싫어한다. 절대 앞으로 걔네들 네트워크에 전개 못할거라 한다. 왜냐면 운용과 확장/축소 입상에서 GPON은 골칫거리가 많으니까.

"Then there are customers in Europe that are looking at GPON," he admitted, "but they are reevaluating their decisions based on the fact that now there’s another solution in town."

다른 유럽 커스터머들은 GPON을 보고 있는데, 걔네들은 다른 솔루션이 있기에 아직 결정을 못하고 있다... 그 솔루션이 WDM-PON 이라는 것?


While there is certainly a great deal of PON and active Ethernet already deployed in Europe, there isn't a clear-cut front-runner, and that makes me wonder if European operators will be more likely to consider WDM-PON versus some version of 10G PON going forward.

유럽에 이미 많은 PON과 active Ethernet 이 깔려 있지만, 딱히 선두주자라 부를만 한 넘은 없다. 그래서 나는 유럽애들이 진행되고 있는 10G PON보다 WDM-PON을 고려하고 있는 것이 아닌가 한다.

What do you think? Feel free to respond to this post or drop me an email (meghanf@pennwell.com) with your thoughts on the subject. I'm thinking about writing a follow-up article that tackles this very question.

I think whether WDM-PON is good or not is fully depending on the pattern of traffice of applications. If down- and up- streams are equal, the WDM-PON is better than TDM-PON, otherwise TDM-PON is better. Some say that WDM-PON is expensive. It's not true. Optiblue, Inc. (www.optiblue.co.kr) is providing low-cost WDM-PON already.
About the traffic pattern, I'm confident that it would be like P2P because of wide use of VoIP with video functions and vidoe clip upload and interactive home game.

WDM-PON 이 좋냐 나쁘냐는 어플리케이션의 트래픽 패턴에 의존한다고 본다. Upstream과 downstream 이 같다면, WDM-PON이 TDM-PON보다 낫다. 그게 아니면 TDM-PON이 더 낫다.

어떤 넘들은 WDM-PON이 비싸다고 하는데 한국에 www.optiblue.co.kr 같은 애들은 저가의 WDM-PON을 제공하고 있다.

트래픽 패턴에 대해서는 이건 P2P랑 비슷하다고 본다. VoIP나 영상통화, 비디오 업로드 그리고 인터렉티브 비디오게임처럼..

Actually, the upstream / downstream traffic balance was much closer to being symmetric (1:1.4) than it is now (1:2.1) and increasing. Mainly the video hosting websites like YouTube etc. are responsible for that. People do not use P2P so heavily any more in certain countries because of legal constraints. So unless P2P becomes legal or there is another killer app with symmetric bandwidth requirements, TDM-PON does not seem to look so much less attractive than WDM-PON.

지금 u/d 비율은 1:2.1 정도 되는데 예전에는 1:1.4정도로 비교적 대칭적이었다. 지금은 증가하고 있다. 이유는 youtube같은 비이오 호스팅 사이트들 때문이다.

사람들은 더 이상 P2P를 많이 쓰지 않는데, 법적 문제때문이지. P2P가 합법적이 되거나 혹은 또 다른 킬러앱이 있다면 대칭적 대역폭 요구가 있겠지만.. 안그렇다. 즉, 지금은 비대칭이어도 상관 없다.

그래서 TDM 이 WDM 에 비해 그리 나쁘지는 않다고 본다
