Mac,

As the channel spacing narrows, its ability to carry the bit rate is reduced. In theory, a 1G channel spacing is limited to a 1G bit rate. The bottom line is that we are quickly approaching fundamental limits of bandwidth over fiber.

Ciena has announced that it will have a 320 channel system next year using its proprietary Bragg fiber grating technology.

there is a huge difference between making things work in the lab and making it work in the field for long long hours.

Nortel will not have the field to itself. NEC SpectralWave-160 is said to achieve 160 wavelengths on a single fiber at OC-48 and OC-192 rates. AT&T is a major customer for NEC's 32/64 DWDM systems.
