WG3017 4-Channel Multimode Variable Optical Attenuator-850nm, 35dB Range, 0.1dB Step, Open/Closed-Loop, USB/LAN, for 800G Optical Module Parallel Testing & Silicon Photonics Power Balancing

The WG3017 is a 4-channel multimode variable optical attenuator engineered for parallel optical power balancing and attenuation control in high-throughput optical module production and silicon photonics testing. Each of its four independent channels operates at 850±20nm with a 35dB attenuation range, adjustable in 0.1dB steps, allowing simultaneous, synchronized attenuation of multiple multimode paths without sequential reconfiguration. Two adjustment modes—open-loop for fast set-and-hold operation, closed-loop for stable power-locked output—make it equally suited to rapid production-line tuning and lab-grade loss simulation. An integrated output power monitor (−50 to +10dBm, ±0.1dB accuracy) provides real-time verification without an external meter, while 0.01dB output stability and <2.0dB insertion loss preserve measurement integrity across repeated test cycles. USB and LAN interfaces support full program control for ATE integration. The WG3017 is purpose-built for 800G optical module parallel testing, ROSA/BOSA device characterization, silicon photonics on-chip power balancing, and optical loss simulation—wherever multiple multimode paths must be attenuated and verified in lockstep. Its benchtop chassis (340×320×88mm, ≤2kg) with 3.5-inch color LCD suits lab benches and production floors alike.
