For several years, North American multiple-service operators (MSOs) have been focused on the commercial services market in an effort to increase and diversify their revenue base. Having addressed the low end of this market with DOCSIS®-based offerings, cable MSOs recognize that continued expansion will require fiber access technologies that can help them deliver the reliability, scalability and bandwidth required for the midmarket and enterprise segments.Many MSOs see passive optical networking (PON) as an ideal technology for supporting commercial services. In the US especially, Ethernet PON (EPON) is increasingly being adopted by MSOs seeking to address business connectivity requirements between 10 Mbps and 1 Gbps, a range that covers the largest and fastest-growing segment of the commercial services market. But MSOs will need economical and scalable provisioning solutions for their EPON networks. With solutions that combine EPON with DOCSIS provisioning of EPON (DPoE™), cable MSOs will have the cost-effective, scalable service delivery platform they need to grow their commercial services business.
