Embodiments of the present technology presented herein relate to a method for configuring a remote node and to a host node for performing said configuring of the remote node. The present technology presented herein also generally relates to embodiments of a method for reconfiguring the host node and to a reconfigurable host node. More particularly, the embodiments presented herein relate to configuring the remote node and reconfiguring the host by duplicating Peripheral Component Interconnect express, PCIe, hot-plug elements such that they are present at both the host node and the remote node. Furthermore there is introduced a connection state indicator at both the host node and the remote node for indicating that an optical connection has been established between the host and remote node.

Method and host node for configuring a remote node and a host node

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.
