Improving Carrier's Cost Structure
Editorial
Anything that improve carrier's cost structure important, both foreseeable future. success multiservice provisioning platforms, CWDM, enhanced protocols such generic framing protocol MPLS give carriers more value fewer dollars while improving efficiency their existing legacy SONET infrastructure. Although these incremental rather than revolutionary improvements network, they critical carriers make progress their efforts make money data. From point view suppliers like Analog Devices, drivers same: make chips faster, more integrated, smaller reduce power consumption while reducing price. Recent signs encouraging. There been much needed consolidation optical components level even some signs pullback sector. Consolidation will contribute healthy recovery; otherwise many companies would chasing sockets when business comes back. Analog Devices' broad base business consumer electronics, industrial instrumentation, automotive electronics allowed ride weakness market like fiber optics maintain long-term focus. market recovers, Analog Devices will able supply broad array analog, DSP, application-specific integrated circuits that central optical networking equipment. During slowdown, remained focused cost, size, power, design time challenges faced module system OEMs metro access optical network equipment. Although many companies reluctant provide particular insight regarding future, still most attention refocused legacy SONET applications telecom space. also speculate that metro will feel capacity pressure soon because carriers running networks historically high utilization rates that will force them purchase metro telecom equipment. With inventories burning network utilization rates continuing rise, there's general sense that carriers will accelerate equipment purchasing late 2004.
