1. A component, comprising:
an electrical interface configured to determine a subset of a plurality of optical channels actively being used to transmit or receive data;
a test generator; and
an optical-electrical converter configured to transmit and receive the data via the subset of the plurality of optical channels,
wherein the test generator is configured to determine, based on the data received by the optical-electrical converter, a status of at least one optical channel of the subset of the plurality of optical channels, and
wherein when the status for the at least one optical channel is determined to be a failure status, the electrical interface is configured to divert data for the at least one optical channel to another optical channel not included within the subset of the plurality of optical channels.
