This account begins in the wee hours of a bitterly cold night in the winter of '92 - '93. A fiber optic transmission system starts to incur unacceptable errors and switches to a protect channel. The system is being run at 1550 nm because it is a route which is long enough to otherwise require a repeater at 1310 nm. OTDR measurement shows high splice losses. By dawn the high-loss splices have partially recovered so the system is switched back to the original fibers. Failure of the mechanical splices is suspected, the RBOC requests post-mortem assistance from Bellcore, and a team is dispatched immediately to work with RBOC personnel in determining the cause of the failure.
