We study an SDN-enabled EPON architecture that utilizes application information from clients to achieve superior upstream resource allocation. This leads to better quality of experience of video-conferencing clients which are high consumers of upstream bandwidth.
As bandwidth requirements of access networks continue to increase rapidly, especially due to the growth of streaming traffic, the need for resolving bandwidth contention among competing users and applications becomes more compelling. The proposed Software-Defined Ethernet Passive Optical Network (EPON) architecture utilizes an application-level feedback from the client side (for video users) to the...
We successfully enhanced reflection tolerance in a single fiber bidirectional WDM-PON based on RSOA where DFB laser diode is utilized as a seeding source. We propose to operate DFB laser diode at its near threshold regime to broaden its spectral linewidth. With such a broadened linewidth, the back-reflection induced beating noise is mitigated, and we can achieve the BER below 10-10 over 20km under...
Chirped waveguide Bragg gratings are fabricated by tapering the width of the core involving uniform grating. A residual dispersion (+170 ps/nm) in a 40-Gb/s transmission system is compensated by adjusting temperature gradients in the waveguide.
