WebMar 19, 2024 · Homodyne detection is the extraction of phase information about a laser by comparing it to a reference beam, referred to as a local oscillator (LO). This is … WebAbstract. This paper focuses on upstream signaling in TWDM-PON (one of the two systems specified in the new series of ITU-T G.989.x Recommendations for NG-PON2), for what concerns the discovery phase of a new ONU. The key idea is that a new ONU, that needs to be discovered by the OLT, would send a low bit rate signal that is set to a ... key west hemingway house cats
