Hi Ray-- Glad you found that exchange interesting. As for the "c" in OC-3c, OC-12c, OC-48c, OC-192c, that stands for
concatenated. A concatenated payload structure allows for
the elimination of unnecessary overhead Bytes in the SONET/SDH frame when there are no sub-rate TDM multiplexed
structures in the frame. In this case, the "c" case, the
entire frame payload is then used for data in a direct fashion.

You might find a recent book published by the IEEE Press of
interest. It is a semi-technical overview of DWDM. "Introduction to DWDM Technology-Data in a Rainbow",
by S. V. Kartalopoulos, IEEE ISBN-0-7803-5399-4.
IEEE Order Number PC5831.
