Title: NODE FOR A FRONTHAUL NETWORK AND MONITORING OF OPTICAL TRASCEIVERS IN FRONTHAUL NETWORKS
Abstract:
A node (30) for use at a main site of a fronthaul network. The node comprises: an optical splitter (32) configured to receive a radio transport optical signal (34) carrying an out-of-band electrical signal comprising an indication of diagnostic monitoring information, DMI, of an optical transceiver, the optical splitter is configured to power split the radio transport optical signal to form a monitoring portion; an optical detector (16) configured to receive the monitoring portion of the radio transport optical signal and configured to convert the monitoring portion of the radio transport optical signal into an electrical signal; diagnostic monitoring interface receiver apparatus (36) configured to extract the out-of-band electrical signal from the electrical signal and configured to obtain the diagnostic monitoring information from the extracted out-of-band electrical signal; and a controller configured to collect the diagnostic monitoring information and configured to transmit the diagnostic monitoring information to a fronthaul network management system.
