IEEE Std 802.3bk ”IEEE Standard for Ethernet Amendment 1: Physical Layer Specifications and Management Parameters for Extended Ethernet Passive Optical Networks” is a subscriber access network technology developed by the IEEE P802.3bk Extended EPON Task Force and approved by the IEEE-SA Standards Board on August 23, 2013.  This amendment defines the Physical Layer (PHY) specifications and management parameters for EPON operation on point-to-multipoint passive optical networks supporting the extended power budget classes of  PX30 (29dB for 1G-EPON), PX40 (33dB for 1G-EPON), PRX40 (33dB for 10/1G-EPON), and PR40 (33dB for 10/10G-EPON).  These new Physical Layer specifications support extended optical loss budgets and higher density and longer reach applications, while optimizing cost of ownership for broadband service providers.

Goals and Objectives for Physical Medium Dependent (PMD) sublayer and medium, type 1000BASE-PX (long wavelength passive optical networks):

  • All 1000BASE-PX PMDs share the objectives of
    • Point-to-multipoint on optical fiber
    • BER better than or equal to 10–12 at the PHY service interface
    • 1000Mb/s on one single-mode fiber
  • 1000BASE-PX10 has an objective of operating at the distance of at least of 10km and at a split ratio of at least of 1:16
  • 1000BASE-PX20 has an objective of operating at the distance of at least of 20km and at a split ratio of at least of 1:16
  • 1000BASE-PX30 has an objective of operating at the distance of at least of 20km and at a split ratio of at least of 1:32
  • 1000BASE-PX40 has an objective of operating at the distance of at least of 20km and at a split ratio of at least of 1:64
