Multichannel Optical Component Analyzer OCA-1000
The OCA- 1000 is a multi-channel optical component analyzer capable of performing simultaneous insertion loss (IL), polarization dependent loss (PDL), and optical power (P) measurements on multiple optical paths. The measurement is based on the Mueller Matrix method, which offers fast characterization of wavelength dependent optical parameters that are critical in today’s optical communication systems. The base model can have up to 8 channels, and the system is expandable to additional sets of channels for maximum flexibility.
The instrument comes with a user-friendly control program with built-in functions to display measured power, IL, and PDL vs. wavelength or to monitor the time variation of power/IL for all channels simultaneously to determine their stability. Other functions available after post processing the data include calculation of the isolation between wavelength channels (adjacent and distant), pass band center frequency, bandwidth, and ripple as well as noise floor.
The OCA-1000 is an ideal solution for easy, accurate characterization of components and modules with multiple outputs, including DWDMs, ROADMs, AWGs and PLCs. It can be used with various tunable lasers, such as those from Keysight or Santec. This flexibility offers the user the opportunity to make full use of his/her laser resources and reduce the cost of making such measurements. Its fast measurement speed reduces the time required to characterize devices with large number of ports, enabling higher production throughput.
