Economics of Resilient TWDM PONs

Journal of Lightwave Technology, 2020
TWDM PON is an emerging access architecture that is capable of offering different categories of services. For example, the operator can provide high-priced failure-proof services to the business users by deploying redundant elements in this network, along with low-priced unprotected service to the residential users.

Redundancy for Long-reach TWDM PON

Optical Fiber Communication Conference, 2018
Two redundancy designs for long-reach TWDM PON without backup OLTs is proposed, protecting the truck fiber and optionally the CO. Network modeling shows availability of redundant long-reach PONs is better than traditional PONs.

Economics of TWDM PONs With Nonlinear Pricing

IEEE Communications Letters, 2019
This letter develops an analytical model to describe the economics of time- and wavelength-division multiplexed (TWDM) passive optical networks (PONs). The network operator is modeled as a profit maximizer that offers multiple subscription plans. The end users either select one of these offers or refrain from availing the service. In this circumstance,

Automatic ONU Wavelength Control in TWDM PONs

Optical Fiber Communication Conference, 2014
Low cost and effective approaches for automatic ONU wavelength control in TWDM PONs are proposed by using low-power and low-frequency/low-data-rate signal from the tunable ONU transmitter. Experimental results validate the proposed approaches.
