Abstract
An Optical Link Management Function “OLMF” for obtaining an optical power level for an optical link between a first and a second optical transformation modules. The OLMF sends a first message instructing a first unit to feed a set of optical transmissions representing at least one bit pattern. The OLMF sends a second message instructing the first optical transformation module to transmit the set of optical transmissions at optical power levels in a range. The OLMF sends a third message instructing a second unit to register successful or unsuccessful decoding of the set of optical transmissions based on the bit pattern. The OLMF receives a set of indications representing successful or unsuccessful decoding of the set of optical transmissions at the optical power levels. The OLMF finds a lowest optical power level for which an optical transmission of the set on the optical link is successfully decoded.
