WG3098 128-Channel Optical Power Meter-Ultra-High-Density Parallel Acquisition for 800G/1.6T Optical Module Production & ATE Integration

The WG3098 is a 128-channel optical power meter engineered for the extreme channel density and throughput demands of 800G/1.6T optical module mass production testing and automated test equipment (ATE) deployment. Its defining capability is full-channel parallel acquisition with a polling cycle of ≤2 seconds (measured ~1.6s) , replacing the hours of repeated fiber mating and sequential single-port measurement that bottleneck conventional multi-channel setups—a workflow that can compress multi-hour test routines into minutes.Channel-to-channel consistency is held to ±0.2dB target / ±0.15dB measured, supported by a dual-gain auto-switching with hysteresis front-end design that preserves stability across the −50 to +10 dBm working range (measured −51 to +11 dBm).A segmented linearity fitting approach across three sub-ranges reduces overall measurement error, while a TEC-based constant-temperature loop on the detector board suppresses low-power drift at elevated production-floor temperatures (drift reduced from ~0.7dB to within 0.1dB at −40dBm under 45°C ambient).The instrument exposes a SCPI-compatible command set over LAN/TCP-IP, enabling direct integration into Python/PyQt or other host-software control frameworks for batch test sequencing, data logging, and pass/fail automation.For production lines testing hundreds of 800G/1.6T modules per day, the WG3098 replaces racks of low-channel-count instruments with a single high-density parallel acquisition unit.
