LARnet, a local access router network

TLDR

The paper proposes and demonstrates LARNet, a novel local access router network. LARNet employs a multifrequency laser matched to a passive waveguide router for downstream transmission and a 1.3‑μm LED for upstream. LARNet resolves spectral alignment issues in WDM networks, shares expensive components among subscribers, and achieves measured aggregate rates of 2 Gbps downstream and 155 Mbps upstream. No further information.

Abstract

A novel local access network, LARNet, is proposed and demonstrated. A multifrequency laser, whose wavelength COMB94 is matched to that of a passive waveguide router in the remote node, is used as a downstream signal source. A 1.3-μm commercially available LED provides the upstream signal. LARNet solves a major problem of WDM networks, the spectral alignment between the optical wavelengths of different channels. Furthermore. The expensive components are shared among all subscribers. Our measurements indicate that aggregate rates of 2 Gbps downstream and 155 Mbps upstream are feasible.
