In this paper, we present and investigate a wavelength-division-multiplexing passive optical
network (WDM-PON) with symmetrical 28 Gbit/s on-off keying (OOK) access signals and 3 …

Nowadays, the designing and development of next-generation 5G communication systems
are in their infancy stage. The incorporation of survivability, reliability, and transmission …

In this paper, we propose an orthogonal frequency division multiplexing (OFDM)-based
metro-access integrated network (MAIN), which enables scalable all-optical virtual private …

We propose and demonstrate a RN (remote node) architecture that enables direct ONU
(Optical Network Unit) internetworking within a group and/or with another groups by using …

In the metro‐access optical network, bandwidth‐allocated mechanism and its algorithm are
proposed for the multi‐subsystem‐based virtual passive optical network (VPON) that can …

Direct communication between optical network units (ONUs) is an important function in
metro-access optical networks. In this paper, a grid architecture supporting the …

Quantum access networks allow a large number of users to access quantum networks,
which can be regarded as an important part of the practical application for quantum …

We propose and experimentally demonstrate a new scheme to support an all-optical virtual
private network (VPN) in orthogonal frequency-division multiple-access passive optical …
