¿µ¹®³»¿ë¿ä¾à This Recommendation specifies the transmission convergence layer of 40 Gigabit-capable passive optical network (NG-PON2) systems providing optical access for residential, business, mobile backhaul, and other applications.
This Recommendation specifies:
- the supported nominal line rate combinations and the layered structure of the NG-PON2 time and wavelength division multiplexing subsystem transmission convergence (TWDM TC) layer; functionality of the TWDM TC service adaptation sublayer, including the use of 10-Gigabit passive optical network (XG-PON) encapsulation method (XGEM), XGEM frame delineation and service data unit (SDU) fragmentation; functionality of the TWDM TC framing sublayer with the specification of the downstream frame and upstream burst formats; functionality of the TWDM TC physical interface (PHY) adaptation sublayer, including synchronization, forward error correction and scrambling; TWDM PON embedded management functionality, including upstream time-division multiple access and dynamic bandwidth assignment mechanisms; the NG-PON2 physical layer operation, administration and management (PLOAM) messaging channel; the optical network unit (ONU) activation cycle state machine, covering activation and wavelength channel handover; timing aspects of TWDM PON point-to-multipoint operation and time-of-day communication; TWDM performance monitoring, supervision, and defects; TWDM security including cryptographic mechanisms for authentication, integrity verification, channel isolation and data protection along with the associated key exchange protocols; signaling mechanisms and protocols to support ONU power management; TWDM wavelength channel management; TWDM system protection; alien device and rogue ONU behavior mitigation; contention-based operation of NG-PON2 system; the layered structure of the NG-PON2 PtP WDM subsystem auxiliary management and control channel transmission convergence (AMCC TC) layer; AMCC TC layer functionality for transparent mode; AMCC TC layer functionality for transcoded mode; functionality of the AMCC TC management service adaptation sublayer; functionality of the AMCC TC framing sublayer; functionality of the AMCC TC PHY adaptation sublayer; 2 Rec. ITU-T G.989.3 (05/2021) functionality of the PtP WDM management framing sublayer; specification of the management data unit (MDU) mapping for AMCC PtP WDM management channel; specification of the PtP WDM management frame format; functionality of the PtP WDM management PHY adaptation sublayer; the PtP WDM ONU activation cycle.
