Bristol 200 and 400 Series Optical Wavelength Meter Calibration and Repair Services

Simbol Test Systems provides professional in-lab Bristol 200 and 400 Series optical wavelength meter calibration and repair services to help maintain accurate, reliable performance for your photonics and optical test equipment. These interferometer-based instruments are widely used for laser characterization, optical transceiver testing, and WDM system evaluation in manufacturing and laboratory environments.

The Bristol 200 Series includes single-wavelength meters optimized for CW laser and transceiver testing. Common models include the 228A, 228B, 238A, and 238B. The Bristol 400 Series includes multi-wavelength meters designed for simultaneous analysis of multiple optical signals in WDM environments. Common models include the 428A, 428B, 438A, and 438B.

These instruments are used for accurate wavelength measurement, optical signal analysis, and test workflows involving transceivers, DFB lasers, VCSELs, and dense wavelength division multiplexing systems. If your unit shows wavelength drift, reduced measurement accuracy, interface faults, display problems, or other operating issues, we can review the failure condition and provide service recommendations based on the exact model configuration.

Following calibration, your equipment may be returned with a calibration label, calibration certificate, and related calibration data. If the unit does not successfully complete calibration, we can evaluate the repair requirements and provide a repair quotation for approval before proceeding.

Traceability: Instrumentation used during this calibration is traceable to N.I.S.T. (National Institute of Standards and Technology) or C.N.R.C. (Canadian National Research Council), where applicable.

Contact Simbol Test Systems with your Bristol 200 or 400 Series model number and a brief description of the issue to request a calibration quote or repair evaluation.
