I'm learning about optical networking at a new job, and am confused by some introductory terminology. I'm pondering this statement:
There is typically one transponder for every client signal and SFP transceiver, however as the DWDM wavelength is at least 10Gigabits per second, smaller client signals, such as 1GbE can be joined up together so that they share the same 10G wavelength.
I'm a bit thrown off by that phrase "10G wavelength."
My understanding is that a wavelength corresponds to a frequency of light, e.g. blue, red, and human-visible colors.
But in regard to a wavelength of light, e.g. something in the C-band - say 1535 nm - traveling down a fiber optic cable...what is the relationship between that 1535 nm wavelength and 10G?
Does that mean, e.g., that if ASK (amplitude shift keying) was the modulation mode, then there could be 10G pulses (whatever combination of "1" or "0") of 1535 nm light per second sent down the fiber?
