In this paper, we firstly review the progress in ultra-dense wavelength division multiplexing
passive optical network (UDWDM-PON), by making use of the key attributes of this …

A low-cost, high-speed SDM-WDM-PON architecture is proposed by using a multi-core fiber
(MCF) and intensity modulation/directly detection (IM/DD). One of the MCF cores is used for …

In one aspect, the present disclosure relates to a communi cations system which, in one
embodiment, includes a phase correlated, orthogonally-polarized, light-stream generator …

This paper demonstrates wavelength reused bidirectional transmission for a reflective
coherent passive optical network (R-Co-PON). By reusing the downstream optical signal as …

We propose a novel architecture for wavelength-division-multiplexed passive optical
network (WDM-PON) that can simultaneously circumvent both remodulation crosstalk and …

In this paper, we have proposed and analyzed a novel cost-effective ultradense wavelength
division multiplexed (UDWDM) passive optical network (PON) which uses phase modulation …

Free-space optic (FSO) with optical metro and access networks should couple very
efficiently since they work in the same wavelengths with a transparent link. Moreover …

The problem of nding the optimal topology for a set of users can be treated as a Steiner Tree
optimization problem, which is a NP-Hard problem. Therefore it must be employed an …
