Core Positioning:

An automated optical testing equipment specifically designed for large-scale status detection of the core component in Wavelength Division Multiplexing (WDM) systems—the filter. It is commonly used in the production of optical communication devices, addressing issues such as low efficiency and high error rates associated with manual inspection.

I. Core Testing Functions

Full-band performance testing: Covers commonly used optical communication bands such as 1250 - 1650nm, comprehensively detecting core optical parameters of filter chips, including insertion loss (IL), return loss (RL), polarization-dependent loss (PDL), adjacent channel isolation, central wavelength, channel bandwidth, ripple (Ripple), and other key indicators. This helps determine whether the filter chip meets the signal transmission requirements of communication systems.

Reliability auxiliary testing: Conducts tests before the product is diced into small pieces, promptly determining qualification to reduce production burdens in subsequent processes and lower costs. It also provides data support for reliability evaluation of filter chips. The equipment automatically stores all test data and displays results graphically, facilitating subsequent traceability and analysis.

II. Key Hardware and Software Configuration

Optical Testing Core Module: The core is equipped with a tunable light source capable of covering a wavelength range of >100nm without mode hopping, with wavelength accuracy reaching ±10pm. Paired with a HOPM high-speed power meter, it supports continuous high-speed acquisition at up to 10KHz, with a dynamic range of +10dBm to -90dBm.

Automated Transmission and Positioning Components: The equipment typically includes a loading unit, robotic arm (transfer unit), and fixing unit. The loading unit can control the movement and rotation of the loading tray via driving cylinders and motors. The robotic arm, equipped with vacuum suction cups and paired with visual positioning components (e.g., positioning CCD), prevents angle deviation during filter transfer, ensuring precise detection positioning.

Self-Developed Integrated Software Platform: The self-developed integrated software platform supports customizable configurations and allows for the addition of testing modules as needed. The software provides an intuitive operation interface, enabling automated control of testing processes while performing integrated operations such as data acquisition, analysis, and storage, minimizing manual intervention.

3. Core Advantages

High Precision and Stability: Leveraging advanced optical technology and algorithms, the wavelength resolution can exceed 1pm, with wavelength accuracy reaching ±5pm. This enables precise detection of subtle performance differences in filters, ensuring reliable test results and addressing errors associated with manual inspection.

Efficient and economical: Utilizing real-time synchronous multiplexing technology of light sources reduces the reliance on multiple expensive tunable light sources, enabling simultaneous testing across multiple stations. The automated loading, testing, and sorting processes significantly enhance detection efficiency and allow one operator to manage multiple devices, lowering labor costs.

Flexible and scalable: The modular design allows the equipment to adjust configurations based on production needs, such as adding test channels or expanding performance testing functions, adapting to WDM filter testing requirements of different specifications and types. Its adaptability surpasses traditional single-function testing equipment.
