Title: Host-based optical frequency tuning
Inventor: STAWROS ORKOPOULOS
IPC: H04B10/40
Filed: 2023-03-07
Abstract: A first host 201, connected to a first tunable small-form pluggable (SFP) module 202 communicates with a second host connected a second tunable SFP module. An optical transport network (OTN) interconnects the two SFP modules. Before data communication can take place, the two SFP modules must be tuned to shared wavelengths. According to the present invention, the host devices participate in this process. The first host 201 outputs an off-keying signal to a hardware pin of the first SFP module, which results in the first SFP module transmitting, on a first channel with a first wavelength, a first notification message 502 including information on the first channel (e.g. its wavelength). The first host receives a notification response message 505 transmitted by the second host device via hardware pins of the first SFP module. The notification response message contains at least the information on the first channel. The first apparatus evaluates the first notification response message. Consequently, a wavelength for transmission from the first host to the second host can be selected. The OTN network may be used for fronthaul communication between an access node and its remote radio heads (RRH).
