Applications Across Industries
The ID OSA is purpose-built for various optical network and photonics testing applications. Its compact design, high resolution, and remote control capabilities make it ideal for R&D labs and production environments.
High-Resolution Spectral Analysis
The ID OSA offers picometer-class resolution (2.5 pm), enabling fine-grained spectral characterisation of optical signals. Whether the user is tuning narrow-linewidth lasers or verifying spectral purity, this tool provides the clarity and accuracy needed for demanding optical analysis tasks.
DWDM Transport Testing
Designed to support Dense Wavelength Division Multiplexing (DWDM) environments, the ID OSA allows network engineers to verify channel spacing, detect crosstalk, and optimise signal performance. Its wide scan range across the C and L bands ensures compatibility with all major ITU grid systems.
OSNR Characterization
With a dynamic range greater than 50 dB and dual input ports, the ID OSA enables precise Optical Signal-to-Noise Ratio (OSNR) measurements — a key performance indicator in both metro and long-haul fibre networks. Accurate OSNR data helps operators assess network health and predict potential failure points.
Modulated Signal Characterisation
As optical networks shift toward coherent modulation formats like QPSK and 16-QAM, accurate spectral insight becomes vital. The ID OSA supports modulated signal diagnostics, allowing you to measure bandwidth usage, evaluate signal shape, and analyse sidebands or distortion in advanced modulation schemes.
Transceiver Testing
Validate the performance of optical transceivers across varying power levels using the ID OSA’s dual input ports. It provides critical data on centre wavelength, spectral width, and signal integrity, helping manufacturers ensure compliance with industry standards before deployment.
