  • Patent number: 10437768
    Abstract: 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.

  • Patent number: 10230460
    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.
