Core Positioning:

A specialized automated optical testing equipment designed for large-scale inspection of filters (Filter), a core component in Wavelength Division Multiplexing (WDM) systems. 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 evaluating the core optical parameters of filters. These include Insertion Loss (IL), Return Loss (RL), Polarization Dependent Loss (PDL), adjacent channel isolation, center wavelength, channel bandwidth, ripple (Ripple), and other key indicators. This determines whether the filter meets the signal transmission requirements of communication systems.

Reliability Auxiliary Testing: Conduct tests before the product is diced into small pieces to promptly determine qualification, reducing production burdens in downstream processes and saving production costs. It also provides data support for reliability evaluation of filter chips while automatically storing all test data and displaying results graphically for easy traceability and analysis.

II. Key Hardware and Software Configurations

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

Automated Transmission and Positioning Components: The equipment typically includes a feeding assembly, robotic arm (transfer assembly), and fixing assembly. The feeding assembly can control the movement and rotation of the feeding tray via drive cylinders and motors; the robotic arm is equipped with vacuum suction cups and works in tandem with visual positioning components (such as positioning CCD) to prevent angle deviation during filter transfer, ensuring precise detection positioning.

Self-Developed Integrated Software Platform: The independently developed integrated software platform supports customizable configurations and can add testing modules as needed. The software provides an intuitive operation interface, enabling automated control of the testing process while performing integrated operations such as data collection, analysis, and storage, minimizing manual intervention.

III. Core Advantages

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

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

Flexible and scalable: The modular design allows equipment configuration to be adjusted according to production needs, such as adding test channels or expanding performance testing capabilities, accommodating DWDM filter testing requirements of different specifications and types, offering stronger adaptability than traditional single-function testing devices.
