16-Channel Variable Optical Attenuator

Multi-channel variable attenuation for optical communication testing and automated test systems

The JW18200-VOA 16-channel variable optical attenuator is designed for high-precision optical communication testing. Its high-density architecture combines multiple independently controlled attenuation channels, helping increase test throughput in parallel test setups. The system also integrates optical power monitoring, output locking, VOA shutoff, and zeroing functions, together with RS-232 and RJ45 communication for remote control and automated test-system integration. This attenuator can be flexibly applied in 800G/1.6T optical module receiver-sensitivity testing, optical link simulation, and transmission-system attenuation testing.

Features
  • High Density Multi-Channel Design
    Supports independent attenuation control across multiple channels, with customizable channel counts. The high-density design accommodates parallel multi-port testing while increasing test throughput within limited system space.
  • Precision Control and Fast Response
    Integrates an optical power meter with fast and precision output modes, along with output locking and VOA shutoff/zeroing functions for repeatable and stable attenuation control.
  • Remote Control and System Integration
    Provides multiple interfaces, such as RS-232 and RJ45, to support synchronized multi-channel control and remote command operation. An open communication protocol facilitates integration with automated test systems.
  • Plug-In Module Design
    The built-in plug-in module design simplifies test setup and allows modules to be installed or removed easily for different testing requirements.
