【Two-Channel Fiber Optic Rotary Joint】
This dual-channel fiber optic rotary joint is engineered for photoelectric theodolites and precision optical systems, enabling reliable transmission of two independent optical signals between rotating and stationary components. Utilizing advanced optical coupling technology, the product maintains signal continuity during 360° unrestricted rotation, effectively eliminating cable winding issues in dynamic measurement applications.
Technical Highlights:
- Dual-channel isolation: Provides >50dB channel isolation to prevent crosstalk between wavelengths.
- Broadband compatibility: Supports 800-1650nm wavelength range with <0.5dB polarization-dependent loss.
- High-speed rotation: Sustains stable performance at 0-300rpm continuous operation (500rpm peak).
- Robust construction: Features corrosion-resistant housing with MIL-STD vibration resistance.
- Maintenance-free operation: Integrated self-lubricating bearing system ensures >10,000 hours MTBF.
Application Scenarios:
Ideal for azimuth/elevation axis systems in optical tracking devices, rotary sensor arrays, automated test equipment, and other scenarios requiring multi-channel optical signal transmission in rotating interfaces.
