craig,

According to IEEE Communications (Feb 1998):

The problems in moving to OC-192 include:

1. Engineering problems

2. Some of the installed fiber is unsuitable for 10 Gb/s speed.

3. Span engineering and the need for signal amplification and regeneration rise as the bit rates rise.

The article actually talks about OC-768 and how most experts doubt that this will be possible in the forseeable future. Fujitsu, Nortel, and Hitachi claimed they had plans for 16 or 32 wavlengths at 10 Gb/s and MCI said it "wanted to" transmit 32 wavelengths at 40 Gb/s or 1.2 Tb/s per fiber.

Clearly, at this point in time the market is so lucrative that many vendors are making claims that do not take points 1-3 into account or the fact that they do not have a product ready to sell.
