An arrangement provides low cost path protection in an optical
communications network. The arrangement has a portion 3 that provides
(broadcasts) an outbound optical signal, and at least first and second
transmitting portions 202, 206 transmit the outbound optical signal
simultaneously onto at least first and second respective mutually
distinct optical pathways 231, 232. Meanwhile, a selection arrangement
204 selects among plural incoming optical signals (via 1, 5) according to
a SELECT control signal 228 to provide a selected signal, and an analyzer
222 analyzes characteristics of the selected signal to provide the SELECT
control signal 228.
