Many large carriers deploying FTTH have adopted Passive Optical Network (PON) based on its native support of legacy telecommunications services, its efficient use of fiber and easy accommodation of cable television services. In general, PON deployments for FTTX applications are growing rapidly. Ethernet PON (EPON) dominates in Asia, while Gigabit PON (GPON) is starting to ramp in North America. Indeed, a recent report from Strategy Analytics (Broadband Service Provider Performance Benchmarking: North America 4Q'08) forecasted 60% growth in U.S. FTTH subscriptions in 2009.
Next-generation EPON deployments are driven by the need for bandwidth intensive triple-play applications and services, such as HD IPTV, video-on-demand, VoIP and peer-to-peer networking. Convergence of business point-to-point fiber services is another key driver. Carriers and Enterprises need networks capable of more efficiently handling and transporting the various types of traffic required by these bandwidth-intensive services. 10G-EPON enables a smooth transition.
While the networks continue to evolve, these next-generation EPON deployments must support asymmetric and symmetric flavors. Coexistence of 1G/10G-EPON is a critical factor for service providers.
Vitesse's current product portfolio can enable 10G-EPON deployments today. With Vitesse's FTTX Technology Ecosystem network, carriers and enterprises can avail themselves of technology expertise for the deployment of 10G and 40G PON in access networks that deliver triple-play services for high-speed data, voice and video transmissions.
