Method and optical link management function for obtaining optical power level for an optical link
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.
