As a project leader at ZTE Corporation, he is responsible for pushing forward the research and standardization in fiber access and home networking of the company, cooperating with the standardization bodies including ITU-T SG15/IEE802.11/IEEE802.3/Broadband Forum/CCSA/ETSI. As an editor, he has participated in drafting more than 10 optical access standards and held more than 40 authorized patents.


Latency sensitive services have attracted much attention lately and imposed stringent requirements on the access network design. Passive optical networks (PONs) provide a potential long-term solution for the underlying transport network supporting these services. This paper discusses latency limitations in PON and recent progress in PON standardization to improve latency. Experimental results of a low latency PON system are presented as a proof of concept.
