| Enough fiber in your diet?
With more services comes the need for more reliability. With that comes the need for redundancy and diverse paths for fiber. Yes, a buried copper line can be damaged just as quickly as a fiber cable can, but comparing the restoration time between a copper cable and, say, an 864-count ribbon fiber (864 individual fiber fusion splices takes a LONG time!) is apples to oranges. Fortunately the operators know of the problems and, at least Comcast, is very heavily into building diverse paths for convergent networking between facilities. I design 'em.
CWDM and DWDM is used more and more frequently to make full use of the fiber plant we already have in virtually all areas, and I can tell you that we're not stingy with putting up major amounts of new fiber for diversity, capacity management, plant hardening, node-splitting and the like. Fortunately Comcast has made a commitment to strengthening the fiber plant, both backbone (long-haul) and local node distribution.
You can never have enough fiber. Period. If you put it up now, there will be a use for it, if not now, then within a couple of years. |
