Abstract
Safety and power control arrangement and method for optical communication apparatus, where a first circuit pack emitting an optical signal (OS) and at least a second and a third circuit pack () are connected in series via optical fibers (). A power monitor () connected to an output () of the at least second circuit pack () reduces the signal power (PW) output from the second circuit pack () to a pre-determined safe value if a loss-of signal monitor () of a next circuit pack () forwards a loss-of-signal control signal (LOC). The advantage is that the maximum allowable value is achieved at the input of an interrupted fiber section and the non-interrupted circuits can still receive the optical signals with a reasonable power level.
