REDUCING CAPEX AND OPEX THROUGH CONVERGED OPTICAL INFRASTRUCTURES

摘要

Today's Cable Operator optical infrastructure designs are becoming more important as customers are increasingly demanding high-bandwidth services such as residential and commercial data and VoD. The network must be able scale to increasing service requirements and customers, be flexible to deliver new services, and be cost effective to lower CapEx and OpEx. At the same time the solution must offer investment protection. To accomplish this, optical equipment vendors are offering a wide array of solutions to allow Cable Operators flexible service offerings while reducing CapEx and OpEx through network convergence. New infrastructure platforms offer a breadth of options for delivering an optical infrastructure based on two primary architectures. Transponders-based solutions integrate DWDM intelligence including auto topology discovery, wavelength provisioning, and auto power management. These platforms can converge the network at multiple layers including DWDM, SONET/SDH, Ethernet, and IP. Passive-based solutions integrate optics into the switch/router via gigabit interface connectors (GBICs) while using passive optical solutions to support native gigabit Ethernet solutions. Both solutions enable the Cable Operator to offer new revenue generating services while optimizing network efficiency, lowering CapEx, and lowering OpEx.
