With the 3rd wavelength carriers could double the downstream bandwidth. In that setup, they could send their own IPTV data on the 1550nm wavelength and use the 1490nm exclusively for subscriber data. This would be similar to what NTT is doing, but in the US, the carrier would not need separate receivers for data and video. BTW - I have not heard any carrier plans to implement IPTV in this way. However, it is a option. Carriers may still want to use the 3rd wavelength even if they deploy IPTV. With the 3rd wavelength carriers could double the downstream bandwidth.

One more follow up question. Verizon has stated that they will, sometime in the future when they feel IPTV is truly ready for deployment, drop their RF overlay and deliver their broadcast video in an all IP format, similar to AT&T. Although they will surely have a great number of deployed triplexers and ONT's in the field by that time, will delivering broadcast video along with VOD and voice over the data wavelength completely eliminate the need for the RF overlay/1550nm wavelength and thus future triplexers? Or will this still be an application where the triplexer can fit in? Or just a diplexer? Thanks. Thanks for the detailed response Brad. One more follow up question.

The video is delivered to a separate unit called a V-ONU. From what I know, it has it own optical interface. I imagine an external filter would be used to split off the 1550 nm wavelength, eliminating the need to replace, or redesign the current data only ONU. Also, I have heard that this is a 10G signal. On WDM PON, I am not sure what NTT’s take on it. From what I have seen, WDM PON has the most potential as a metro or “2nd to last mile”. Currently, KT and LG are demonstrating a 100M system, but I think their goal is offer a 1G system. With 1G WDM PON system, they could service businesses, large apartment towers/complexes, and remote DSLAMs more cost effectively than traditional switched Ethernet. One other note, SBC is not following the same path as VZ. They are deploying an IP based video solution and have indicated that their service will be enhanced over what the MSO offer today.

As far as Japanese telecom regulatory info, you might want to shoot an email to Meghan Fuller, senior news editor at Lightwave: meghanf@pennwell.com. She wrote a very informative article some time back that was reprinted in several online publications: http://lw.pennnet.com/Articles/Article_Display.cfm?Section=ARCHI&ARTICLE_ID=217947&VERSION_NUM=2&p=13&pc=ENL She might be able to give you some guidance. Also, you seem to have not only a genuine interest but excellent depth of knowledge in terms of what is currently happening in FTTH today. Two questions. First, how do you see WDM PON technology fitting into the Japanese deployments since this "triplexerless" multimode fiber technology seems to be a possible option. Second, since you raised the possibility before in another post, do you see MRV's Luminent division as having the potential to deploy their triplexer product into these Asian video deployments? They certainly seem to have more experience with the scale needed than anyone else currently out there as well as the means of production (assuming, of course, that the above architecture is eventually deployed).
