<<The more profound effects, I believe, will be to break the lock that the industry now has been subjected to by yet another seemingly cast in stone approach, namely WDM, to increasing transport capacity on fiber >>
First let me say that this thread's technical level is way beyond my skills.
However, let me venture a question anyway - don't bite my head off.
Silkroad claims a 90+GB/sec pipe using only one wavelength, thus faster, cheaper, simpler, etc. than DWDM - and the technology is supposedly scalable to the terabit/sec range.
But DWDM so far I think has been simply increasing the number of wavelengths sending concurrent OC-48 datastreams - probably because this is a common connection speed today.
Surely this is not anywhere near the limits of this technology? If pushed, cannot the existing DWDM technology increase to OC-192 or OC-768 data streams without great add-on cost, instead of moving to say 120 wavelengths from 80?
In other words DWDM is now the entrenched technology. "Breaking that lock" may be more difficult than it might seem at first glance, if the industry responds for the first time to a challenging technology. |
