Jingyi Optoelectronics Laser Wavelength Analyzer: The Ideal Choice for Optical Communication Testing
The deployment of emerging applications—such as 8K ultra-high-definition live broadcasting, millisecond-level autonomous driving response, and cross-regional computing resource scheduling—fundamentally relies on continuous upgrades in optical communication network bandwidth. Today, 100G optical transmission is fully mature; 400G networks have entered large-scale commercial deployment; and technological evolution toward 800G and even 1.6T ultra-high-speed optical transmission is accelerating rapidly. To achieve multi-fold bandwidth expansion over existing fiber infrastructure, the core lies in maximizing spectral resource utilization via technologies such as DWDM (Dense Wavelength Division Multiplexing), coherent modulation, and polarization multiplexing—placing near-exacting demands on parameter accuracy across the entire optical communication chain.
Whether it’s wavelength stability or linewidth fluctuation of light sources, chirp effects in modulators, polarization responses of passive components, or dispersion deviations during transmission—even a single parameter deviating beyond the parts-per-trillion (ppm) level can cause a dramatic surge in bit-error rate (BER) for ultra-high-speed optical signals, or even render them completely undeliverable. High-precision laser wavelength and spectral measurement has thus become a critical enabler across optical device manufacturing, network operation & maintenance (O&M), and cutting-edge R&D.
Addressing the optical communication industry’s multifaceted requirements for test equipment—precision, efficiency, and portability—Jingyi Optoelectronics’ Laser Wavelength Analyzer breaks free from the traditional trade-off between “lab-grade accuracy with poor portability” and “portable devices with insufficient accuracy.” Leveraging proprietary high-resolution spectral optics, stray-light suppression architecture, and real-time calibration algorithms, the analyzer achieves an optimal balance of performance and usability. With only a simple connection of the light source to the sampling probe, it delivers full-dimensional parameters—including peak wavelength, full width at half maximum (FWHM), and side-mode suppression ratio (SMSR)—within milliseconds. Its ultra-low-stray-light design minimizes background noise interference, achieving measurement accuracy of ±0.15 ppm. It supports both continuous-wave (CW) and pulsed laser modes, comprehensively covering mainstream testing requirements across today’s optical communication domain.
In optical component manufacturing, Jingyi’s Laser Wavelength Analyzer replaces multiple conventional test instruments. A single unit can perform factory calibration for tunable lasers, optical transceivers, and DWDM components—enabling dynamic sampling at up to 1,000 times per second and simultaneous wavelength measurement across thousands of channels. Its built-in real-time calibration module eliminates the need for external calibration sources or periodic off-site recalibration, enabling seamless integration into production-line workflows. This boosts calibration efficiency for 400G/800G optical modules by over 40%, significantly reducing inspection costs at the manufacturing stage.
For optical network O&M, the analyzer’s portable design empowers field technicians to conduct rapid on-site diagnostics—without removing faulty components from the fiber link and returning them to the lab. Key parameters—including wavelength drift, optical signal-to-noise ratio (OSNR), and FWHM fluctuations—can be assessed directly at the site. What previously took hours can now be completed in under 15 minutes, dramatically accelerating troubleshooting responsiveness across ultra-high-speed optical networks.
For cutting-edge R&D in optical communications, Jingyi Optoelectronics offers an optional high-resolution spectral analysis module based on this platform, delivering spectral resolution down to 10 MHz. This enables precise characterization of fine-grained parameters—such as phase noise of narrow-linewidth lasers, chirp effects in modulators, and polarization responses of novel multiplexed signals—fully meeting the rigorous test requirements of coherent optical communications, photonic integrated circuits (PICs), and optical frequency combs. Comprehensive multidimensional parameter measurements are achievable without relying on combinations of multiple imported instruments.
As AI-driven computing networks impose ever-increasing demands on optical link stability, future optical transmission systems will require *in-service*, real-time monitoring of wavelength and spectral dynamics. Jingyi Optoelectronics is actively developing miniaturized detection modules capable of direct integration into optical transmission equipment and relay sites—enabling continuous, real-time acquisition and feedback of optical link parameters. This provides foundational technical support for intelligent O&M of next-generation 1.6T ultra-high-speed optical networks.
