– Key Features
• Power Control: Directly sets output power level with automatic compensation for input fluctuations
• Integrated Shutter: Enables power meter zeroing, equipment protection, and channel drop simulation
• Low Signal Distortion: Minimized PDL, PMD, and CD for accurate measurements
• Built-in Power Meter: Facilitates real-time power monitoring and control feedback
• Offset Calibration: Corrects for connector and patch cord losses; wavelength-dependent offset pairs stored for wavelength-specific compensation
• Built-in Calibration: Reduces measurement uncertainty and accelerates system calibration
– Typical Applications
• Optical network component characterization
• Telecommunications and data communications testing
• Research and development of optical systems
• Manufacturing test and validation
