re: FiOS Tracker
My limitations, but I can't make much sense out of this posting... Never knew JDS is a communication gear maker. And who said OEO is the best thing in fiberoptics?

"Demand exists, an ability to pay exists, but no market mechanism is fulfiling the need." I like this thoughtful statement. I can't but agree that the business leaders have a lot to cath up with.

re: FiOS Tracker

Yes, I do and they are indoor units without battery backup. They are not that much cheaper than US ONTs. The primary differences are:

- Mechanical
- Power
- 3rd wavelength
- Integrated POTS interfaces

re: FiOS Tracker
Dear dwdm:
JDSU is a huge component vendor, IMHO. That is why I called Rot at the ROOTS. Component business profits are often based on volumes, particularly in commodity businesses. If optical components are commoditizing, then JDSU should be the last to give up, given their size. The fact that they are even potentially considering selling their component business bodes poorly for future investment.

As to the relative merits of OEO, INFN seems to think an integrated system saves big bucks. Perhaps LVLT agrees. I wonder what VZ is using in competitive situations.

re: FiOS Tracker
Tera,
You are correct in that multimode simply will not work. The FSAN standard calls out either 10km or 20 km links. At Gb data rates you can only go a few hundred meters over MM fiber so it's totally out of the question.

dwdm2,
The OEMs are already looking at next gen technologies beyond GPON. At this point in time the leading contenders are probably 10G PON or some sort of WDM PON as you mentioned. Yet seven is correct in that economics will drive this not necessarily the "best" technology. It's all about installed cost. If you have a way to increase bandwith without having to roll a truck to upgrade every ONT in the system your equipment cost could actually be higher. It'll be interesting to see who wins the day.......

re: FiOS Tracker
Japan's pon network is built using diplexors or so called "bidi's". Only 1 optical transmitter and one receiver. North America to date is using triplexors. 3 wavelenghts: 1 for video RX, 1 for Data & POTS RX, and one for Data TX.

Hence higher costs.

also Japan (NTT and Yahoo BB) has been deploying for much longer than North American operators. They are further into the volume ramp and hence further into cost reduction curve than North American operators. Tellabs and Motorola are selling mostly triplexors into north american market.

This will change as operators in north america move to a diplexor or bidi type architechture. This is coming with GPON.

Also in Japan, the Japanese operators buy the optics for the ONT deeper into the supplier food chain. Tellabs and Moto and ALU buy stuff from PON suppliers who then source the optical TOSA from others in the middle of the food chain and then those middle companies source from asian base component suppliers. Extra layers in middle of value chain also adds to Tellabs and Moto costs.

re: FiOS Tracker
There have been all sorts of revenue & cost/customer numbers put out by Verizon and by various analysts who follow FiOS. One thing that I haven't seen, to any real extent, is the impact of cannibalizing Verizon's DSL offerings in areas now serviced by FiOS.

For example: Prior to FiOS there were X Verizon DSL customers who contributed $Y ARPU. Now, with FiOS, there are A FiOS customers. How many of the X customers are now included in A and what is the delta in ARPU? Spending $1700+/existing-DSL-customer would surely put the FiOS ROI (which would be based on the ARPU delta, not simply the ARPU) well beyond the decade mark.

I understand that Verizon is still claiming significant growth in DSL as well. My guess is that this is more a factor of re-deploying the DSL equipment that was displaced by FiOS to areas that previously did not have DSL service.

Steve.

re: FiOS Tracker

Actually the 3rd wavelength is possible in EPON as well but NTT does not have the legal right to carry video at the moment, so it does not make sense.

There were also products called "bidi's" using some optical processing which ran both directions under a single wavelength.

You mean data only goes in one direction in Japan? ;)

All three: BPON, GPON, EPON transmit/receive over one fiber, so they use two wavelengths for IP traffic. One for upload, and one for download.

BPON/GPON have the option of muxing in a third wavelength for unidirectional video--kind of like cable over fiber. It saves cost in the short term because Verizon doesn't have to have an IPTV infrastructure set up yet.
