Abstract

We discuss the use of energy-saving 10 Gbps vertical-cavity surface-emitting lasers (VCSELs) as optical network unit (ONU) transmitters in passive optical networks. In particular, we review the features and properties of the VCSEL that enable energy-savings to be achieved. The power consumption per customer using VCSEL-ONUs and DFB-ONUs, is compared through an illustrative example of 10G passive optical network for Video-on-Demand delivery. An impact study of network and protocol parameters on the achievable energy-savings of VCSEL-ONUs over DFB-ONUs, is presented.
