WG3026 4-Channel Single-Mode Variable Optical Attenuator-MEMS VOA, 20 Calibrated Wavelengths, 0.1dB Step, Per-Channel Output Monitoring, USB/RS232, for 800G/1.6T Optical Module Production Test

The WG3026 is a 4-channel single-mode variable optical attenuator built on MEMS VOA technology, engineered for parallel attenuation and power balancing in single-mode optical module production and device testing. Each of its four independent channels supports individual wavelength configuration across up to 20 rigorously calibrated wavelengths, covering the 1310/1490/1550nm single-mode windows—a critical capability when a single test station must verify ports operating at different wavelengths without swapping setups. Attenuation is adjustable in 0.1dB steps across a wide dynamic range, with per-channel output power monitoring providing real-time verification without an external meter. USB and RS232 interfaces support full program control for integration into automated test systems, while a 3.5-inch color LCD and front-panel keys enable standalone operation. The WG3026 is purpose-built for 800G/1.6T single-mode optical module production testing, ROSA/BOSA characterization, system loss simulation, and lab R&D—wherever multiple single-mode paths must be attenuated and verified in lockstep. Its benchtop chassis and AC power input suit both lab benches and production floors.
