Abstract
Conference Title: 2017 Asia Communications and Photonics Conference (ACP) Conference Start Date: 2017, Nov. 10 Conference End Date: 2017, Nov. 13 Conference Location: Guangzhou, China We demonstrate the viability of widely tunable far-L-band injection-locked quantum- dash laser as a source for NG-PONs by successful 128 Gb/s DP-QPSK transmission over ∼1621 nm subcarrier, and reaching a potential capacity of ∼4.0 Tb/s.
