Wavelength Drift of Burst-Mode DML for TWDM-PON [Invited]
Journal of Optical Communications and Networking, 2014Thermally tunable burst-mode directly modulated lasers (DMLs) are the lowest-cost choices for the optical network units in time and wavelength division multiplexed passive optical network (TWDM-PON) systems. However, a fast wavelength drift caused by the burst-mode operation of this directly modulated distributed feedback laser needs to be considered ...

The Next Step for NG-PON2: 50G TWDM-PON
InnovActionAs broadband demand accelerates and digital services become increasingly bandwidth-intensive, the evolution of Next-Generation Passive Optical Networks (NG-PON2) is entering a pivotal phase. This article explores the transition toward 50G Time and Wavelength Division Multiplexed PON (TWDM-PON) as the natural progression of NG-PON2.
