Sigma Networks has deployed CIENA Corp.'s intelligent optical core switching solutions to power its hubbed MAINLink SONET services, designed to provide carrier-class SONET performance and availability.
CIENA's Multiwave CoreDirector and Multiwave CoreDirector CI intelligent optical core switches enable Sigma Networks to deliver switched, channelized SONET services in a metro network. Its fractional SONET capabilities allow Sigma Networks' carrier and service provider customers to use a single aggregated port connection to reach multiple points-of-presence in major cities. CIENA's CoreDirector enables switching at the STS-1 level for the distribution of DS3s, OC-3s, OC-12s, and OC-48s throughout the metro.
Sigma Networks hubbed SONET Services are designed to help customers reduce costs via economies of scale. For example, rather than ordering four separate OC-3 metro point-to-point connections, a customer could reduce its costs per year with the hubbed SONET services by provisioning one aggregated OC-12 port with channelized, switched delivery to four different OC-3s at four different end locations, claims the company.
CIENA Corp.'s (Linthicum, MD) LightWorks architecture enables optical services designed to change the economics of service-provider networks by simplifying the network and reducing operational costs. Additional information about CIENA can be found at www.ciena.com.
Sigma Networks' (San Jose) all-optical Metro Area Interconnection Network (MAIN) offers a line of metro interconnections, including SONET, Gigabit Ethernet, and wavelength services designed to accelerate carrier and service provider network footprint expansion and ROI.
