Oceania’s optical test market, especially Australia, sees surging demand for polarization-maintaining optical components driven by telecom lab upgrading, fiber laser R&D and coherent signal testing. Conventional PM VOAs sold locally have obvious drawbacks: low attenuation precision, limited wavelength bands, high insertion loss and large packaging size.

Gezhi Photonics’ 532–2050nm PM VOA fills this market gap, supporting full-spectrum polarization-sensitive testing. This case covers a bulk order of 6,800 units shipped to Australia within 6 weeks for optical communication system testing.

• 1310/1550nm coherent transceiver attenuation calibration
• 980/1064/2000/2050nm high-power fiber laser polarization testing
• 532–850nm visible light lab optical sensing experiments

• Competitor PM VOAs only reach 0.1dB adjustment precision, causing unstable test data
• Single-wavelength devices force multi-model stock, raising inventory costs
• Max power handling below 200mW, incompatible with high-power pump lasers
• Oversized packaging hard to integrate into compact test benches
• Long overseas supplier lead times delay project delivery

• Dedicated automatic production line for 6,800 units batch manufacturing
• Pre-batch attenuation precision calibration to ensure consistent performance
• Priority sea freight + pre-completed Australian customs clearance documents
• Full quantity delivery finished within agreed 6-week timeline

“Gezhi’s PM Manual VOAs completely solved our multi-band optical communication testing pain points. We will use this series as standard components for all test benches and place repeat orders for 2000/2050nm mid-infrared laser testing equipment.”

• This Australian 6,800-unit bulk PM VOA project fully demonstrates Gezhi Photonics’ core product strengths via visualized tables and schematic drawings:
• Ultra-fine 0.02dB attenuation precision, covering 532–2050nm full spectrum to match multi-scenario optical communication testing;
• Excellent optical indicators: low insertion loss, high extinction ratio, 500mW high power tolerance and stable wide-temperature performance;
• Compact 26×18×8mm standardized packaging with fully customizable wavelength, fiber and connector options;
• Reliable mass production capacity to fulfill large-volume orders within tight 6-week lead times.

For Australian telecom labs, university photonics facilities and optical test equipment manufacturers, Gezhi PM Manual Variable Optical Attenuator is a one-stop polarization-maintaining attenuation solution to resolve common testing defects of traditional VOAs.
