Upgrading the Optical Communication Industry: JINGYI Optoelectronics’ Integrating Sphere Wavelength Analyzer Empowers Progress  

Currently, the rapid expansion of the digital economy is continuously driving upgrades in the capacity of optical communication networks. Emerging applications—including AI-generated content (AIGC) computing interconnectivity, ultra-low-latency vehicle-road cooperative transmission, and 8K ultra-high-definition content distribution—have collectively propelled 400G optical transmission into mainstream deployment, while commercial rollout of 800G—and even 1.6T—ultra-high-speed transmission networks is now entering its final countdown.  

Without large-scale replacement of existing fiber infrastructure, the industry widely adopts technologies such as Dense Wavelength Division Multiplexing (DWDM), coherent modulation, and polarization multiplexing to fully exploit spectral resources—thereby achieving multi-fold increases in transmission capacity. However, such high-density spectral utilization imposes nanometer- or even picometer-level precision requirements on critical optical signal parameters, including wavelength accuracy, linewidth stability, and phase noise level. A mere 1-pm wavelength drift in a laser source can cause adjacent-channel crosstalk, directly elevating the bit error rate across the entire transmission link. Consequently, high-precision laser wavelength and spectral measurement has become a core enabler across the upstream optical communication value chain—from device R&D and production-line calibration to network operation and maintenance.  

To meet the optical communication industry’s dual demands for efficiency and ultra-high precision in wavelength calibration, JINGYI Optoelectronics has launched its Integrating Sphere Wavelength Analyzer—breaking away from traditional measurement instruments characterized by bulky size, complex calibration procedures, and lengthy testing cycles. Equipped with an in-house-developed low-stray-light spectroscopic module, the analyzer enables users to simply align the light source under test with the collection probe and obtain key parameters—including peak wavelength and full width at half maximum (FWHM)—within milliseconds. Its superior measurement accuracy fully satisfies calibration requirements across mainstream optical communication production lines and research laboratories. Moreover, it supports versatile adaptation to both continuous-wave (CW) and pulsed lasers, and allows flexible spectral range extension tailored to diverse band-specific detection needs. Compared to conventional imported analyzers, it delivers over 40% higher cost-effectiveness—fully aligning with domestic optical communication manufacturers’ R&D and mass-production calibration requirements.  

Addressing the demand for fine-grained spectral analysis introduced by emerging technologies—including coherent modulation and optical orthogonal frequency-division multiplexing (OOFDM)—in ultra-high-speed optical communications, JINGYI Optoelectronics’ series of high-resolution spectral measurement solutions achieve spectral resolution down to 10 MHz and wavelength detection accuracy as high as ±0.5 pm. These systems accurately capture subtle parameter variations—including polarization characteristics, phase noise, and chirp effects—with dynamic ranges exceeding 80 dB. Crucially, they eliminate spurious signal interference commonly encountered with traditional grating-based spectrum analyzers—faithfully reconstructing the complete spectral profile of optical signals.  

Today, this solution already covers multiple core scenarios across the full optical communication value chain:  
- In laser source R&D: supporting linewidth testing and wavelength stability calibration for DFB lasers, VCSELs, and tunable lasers;  
- In optical transceiver mass production: enabling batch wavelength calibration and rapid side-mode suppression ratio (SMSR) testing for WDM transceivers—processing over 1,000 modules per hour per unit, delivering more than threefold efficiency gains versus traditional methods;  
- In network operations and maintenance: facilitating OSNR measurement and channel crosstalk diagnostics for DWDM transmission links—providing accurate data support for stable ultra-high-speed optical network operation;  
- Additionally, in emerging application areas—including photonic integrated circuit (PIC) testing and fiber Bragg grating (FBG) sensor calibration—the solution offers multidimensional parameter measurement capabilities.  

As the all-optical network advances further, spectral resource utilization in optical communication networks will continue rising—raising even stricter demands on laser measurement accuracy and speed. JINGYI Optoelectronics remains committed to iterating its measurement technologies in direct response to real-world industry needs—launching more cost-effective, domestically adaptable solutions to accelerate China’s optical communication industry toward self-reliance and secure, controllable development.
