RE:Self-healing: Is that to say that it's self-healing to nicks and scrapes, but not to limb-severing wounds? Geographic diversity of the cable routes (i.e the redundant path is physically separated by some distance greater than the bucket width of a backhoe, and preferably many miles) is the only way to achieve this, correct? [Maybe they can market this as Spatial Division Multiplexing<gg>]. Do the undersea routes have such geographic separation of redundant paths typically? Also, regarding splices in FO cable, over time this gets potentially as ugly as the many-decades-old spliced-together copper infrastructure(including coax) unless there exists some "zero-loss" splice. For the case where there isn't enough slack to do a direct splice, 2 splices per cut...can add up quickly. Are the FO cable bundles typically wrapped in some metallic conductor or metallized conduit to aid in surface detection of their location? dh
