Key features

  • Industry’s fastest swept wavelength measurement of insertion loss (IL) and return loss (RL)
  • >70 dB insertion loss dynamic range in a single scan at full speed
  • ±5 pm wavelength accuracy and 1 pm sampling resolution at full speed
  • Accurate measurement of steep components with slopes up to 10 dB/pm (10,000 dB/nm)
  • Scalable architecture for laser sharing among up to 8 test stations


  • PIC wafer-level testing
  • Multiple-output passive optical component testing in manufacturing and R&D
  • WSS and ROADM calibration and tests
  • Thin film filters (TFF) characterization


The CTP10 is a modular measurement platform for efficient 24/7 testing of passive components. It lets you perform single-sweep insertion loss and return loss measurements with an unprecedented dynamic range, speed and resolution. The CTP10 is the ideal instrument for the characterization of large port number components used in WDM networks and photonic integrated circuits (PIC). It operates together with the T100S-HP series of swept tunable laser to perform IL-RL measurements within seconds.

Next-gen platform and modules

The CTP10 platform hosts up to 10 hot-swappable modules. It has an embedded operating system for handling and processing large amounts of data. It also offers a scalable architecture to share one or several tunable lasers among up to 8 test stations.

Unparalleled performance

The CTP10 yields the fastest swept insertion loss and return loss measurements in the industry. It offers uncompromising performance and maintains best-in-class specifications at full speed. The range-free series of OPMx optical detectors can measure a dynamic range of >70 dB in a single sweep at 100 nm/s, with a 1-pm resolution, drastically increasing throughput in manufacturing and R&D. The OPMx detectors can also accurately measure extremely sharp spectral features of up to 10 dB/pm (10,000 dB/nm), making the CTP10 future-proof to measure next generation components such as wavelength selective switches (WSS) or ring-resonators.

Powerful intuitive GUI

Its embedded software offers a powerful and intuitive GUI, simplifying test configuration and measurement. The CTP10 seamlessly controls external tunable laser(s) to let you focus on what really matters: measurement data and analysis. The GUI integrates a full suite of tools to analyze pass-band (e.g., WDM or WSS) and stop-band filters.
