re: Nokia Siemens Dumps on GPON It's possible that NSN has made the right decision for its own business RIGHT NOW, but is it also possible that NSN might be reducing its chances of being a market leader in the next wave of PON access deployments by stepping away from the GPON melting pot?

re: Nokia Siemens Dumps on GPON ... was my first thought upon seeing this. Purely business reasons cited by both, and rather short sited reasoning if I remember correctly.

GPON is spawning necesary IP that can be made to do more than just what the FSAN/ITU standard will lay out. I'm grateful to folks taking on investment in any of the technologies really. 'sort of afraid of the variety & complexities approaching that of xDSL and wireless, but that's job growth one can argue!

re: Nokia Siemens Dumps on GPON I guess NSN has come to the same conclusion as Nortel - WDM-PON will be the end game for FTTH. They have sold their entire stake (50%+) in Dasan, the South Korean market leader in GE-PON. Until WDM-PON becomes widespread, they hope to sell VDSL2 thus dissing GPON. Pure politics re. VDSL2 and in the end it could end up being a wise decision to go the lambda route.

re: Nokia Siemens Dumps on GPON Interesting that they are pushing the AT&T argument over the Verizon argument.

I've seen AT&T VRAD boxes. I could hear the fans trying to cool down the internal chassis in the hot sun. This isn't a bunch of chassis inside a CO building somewhere--these are outside, sprinkled all over the neighborhood--exposed to hot sun, rain, snow, hurricanes--you name it. When something in the electronics blows (and this will invariably happen), you have to send out a tech to drive around the neighborhood and try to debug and fix the problem outside, potentially in the middle of a freezing snowstorm.

In an era when CO's income, costs, and staffs are shrinking (or should be), these companies are signing themselves up to a labor-intensive, outdoor high-maintenance problem for the rest of time (or until they realize their mistake).

GPON has no active electronics in outside boxes. It is fiber from the CO to the home with passive splitters in between. Maybe initial costs are higher, but long term it will be much cheaper. And once the fiber is in, other technologies can be implemented as they improve. In other words, there's lots of room to grow, as opposed to a high-maintenance dead-end.

Harsh words, but the customer is the one who ultimately loses out when short-sighted cheapskates (and their sour-grapes vendors) try to keep low-bandwidth copper alive.

re: Nokia Siemens Dumps on GPON NSN is so full of it, guess since they had no shot at GPON they can say anything they want now. reality is GPON is being used globally by many carries now (including VZ and AT&T here in USA) and the evolution from 2.5G to 10G PON will give it a long life indeed. The same argument that this idiot uses for copper (VDSL2) can be extended to fiber. NSN you guys lose... just admit it....

re: Nokia Siemens Dumps on GPON Yes Like Nortel has made allot of wise decsions lately huh? The reality is this, GPON will be widely deployedfor the next several years. It's got a ton of runway with 10G PON coming next. Everybody knows that the key cost issue for the carries is the fiber runs (in the last mile) not the technology being used. Once they have invested in the fiber for FTTH they can move along the technology curve as needed (GPON @ 2.5G, the @ 10G then move to Lambda's - all this is business case driven)

End of story!

re: Nokia Siemens Dumps on GPON Telecomm used to be built on some sort of grand-unification schemes. However, the reality today is very diversified so much so that everyone (including both carriers and vendors) can only take one area that they think best fits their game to start with.

From technology point of view, if GPON is going to be obsolete when WDN-PON comes around, VDSL local loop is already obsolete. But this is only technology we are talking about here. There are still market segments that are perfect for VDSL.

NSN cannot catch GPON, then why not scale back to copper. To justify their position, they will use WDM-PON to slow down G-PON if they can.

When WDP-PON is indeed here someday, let's see where NSN would be at.

re: Nokia Siemens Dumps on GPON I never argued that GPON will be widely deployed - and so will WDM-PON. Sooner rather than later (citation from HR). Oh, and if the fiber run is the key kost (which it is) - why not go lambda straight away? Several operators are talking about going that route, skipping GPON all together (and don't pull the VZ/ATT card - the world is much bigger than the US)
telecom_guru 12/5/2012 | 3:30:19 PM
re: Nokia Siemens Dumps on GPON yes yur scenario is possible but I'm thinking unlikely.. and it's not just VZ and AT&T going with GPON for FTTH, my information suggeste that there are several other large carries, outside NA, looking to do the same. WDM PON needs to mature much more b4 one can conside it replacement for GPON.

re: Nokia Siemens Dumps on GPON yes, those are typos. my bad, my fat fingers too.
