The WG3037 is a 24-channel benchtop optical power meter built for high-density parallel testing in optical device production, transceiver tuning, and fiber network verification. Based on a card-insertion architecture, all 24 channels operate independently with per-channel wavelength settings across 21 commonly used wavelengths from 850nm to 1650nm, including 1270/1290/1310/1330/1490/1550/1577/1625nm. The InGaAs detector delivers 0.1dB accuracy, 0.01dB resolution, and a measurement range of −70 to +10 dBm (Type A) or −50 to +27 dBm (Type B), with fast refresh rates and a color LCD for real-time monitoring of all channels. USB and LAN interfaces support full SCPI program control, enabling seamless integration into automated production lines and lab test systems. The WG3037 is particularly suited to optical module R&D and volume production, MPO/multi-fiber array measurement, optical device inspection, and automated test equipment deployment. Its compact benchtop form factor (450×360×132mm, ≤5.0kg) and AC 100–250V universal power input make it ready for global deployment.
