10G PON Technology Evolution

This article first goes through the different ITU-T standards of 10G PON with relevant definition of wavelengths. Particularly this article shares the view of the latest XGS-PON standard, including its Transmission Convergence sub-layer and Physical Medium Dependent sub-layer, compatibility design with current PON approach and migration solution. This article also lists the latest global customer lab testing with XGS-PON and optical modules development. Finally it summarizes the next evolution of overall 10G PON and brief of XGS-PON opportunity today Key wordsXGS-PONXG-PON1NG-PON210G EPON10G PON evolution 0 PONPassive Optical Network/ FTTx PON GPON 2.5Gb/s 1.25Gb/s EPON ( 1.25Gb/s 10Gb/s PON 10G PON 1 PON PON 1995 10 PON 2005 IEEE ITU-T PON IEEE 2006 10G EPON IEEE 802.3av 2009 9 10G EPON 10Gb/s 1Gb/s 10Gb/s ITU-T 2008 GPON NG-PON1 NG-PON2 NG-PON1 PON GPON NG-PON2 PON NG-PON1 XG-PON1 XG-PON2 XG-PON1 10Gb/s 2.5Gb/sXG-PON2 10Gb/s , 10G PON , ITU G.987XG-PON1) XG-PON1 XG-PON XG-PON1
