According to the study (The Business Case for Carrier Ethernet over MSPP SONET Networks), using existing SONET/SDH networks for Carrier Ethernet in smaller cities costs less over five years than deploying an overlay Carrier Ethernet directly over fiber or DWDM transport.
"Smaller cities already have existing SONET/SDH networks deployed for TDM/PDH traffic," said NSP's Peter Fetterolf, Partner and author of the study. "Carrier Ethernet and Triple Play services can be implemented quickly and cost effectively using Ethernet cards on MSPP SONET/SDH nodes. The rollout of a separate Carrier Ethernet network cannot be justified in the short term because smaller cities do not have sufficient fiber connectivity, density or demand."
The study models a rich set of commercial and residential service offerings and calculates revenue, CAPEX, and OPEX for three cities- Boston, MA; Stockton, CA; and Springdale, AR-representing Tier 1 through 3 cities respectively. Financial metrics include cash flow, NPV, ROI, and Payback.
Study Highlights
* Payback for MSPP networks was 2.5-3.6 years for Tier 2-Tier 3 cities
respectively versus 4.7-5.0 years for Carrier Ethernet directly over
fiber or DWDM
* Payback for Tier 1 cities was 1.9 years for MSPP networks versus 1.8
years for Carrier Ethernet direct on fiber justifying immediate build
out of a separate network.
* All cities offering Video on Demand (VoD) should consider using a
dedicated Carrier Ethernet network.
