fiber optical slip ring

Fiber optical slip ring is a precision electro-optical component used to transmit optical signals in a rotating connection. In a device or system, one end is stationary and the other end rotates, achieving continuous and lossless transmission of optical signals without entanglement or interruption.

Advantages

1. Ultra-low insertion loss
The typical insertion loss of this fiber optic slip ring is less than <3 dB (test wavelength is 1310/1550nm), which is significantly better than the common 4-5 dB level in the industry. This low loss feature enables it to effectively reduce optical power attenuation during signal transmission, and is particularly suitable for applications with strict signal strength requirements. At the same time, the stability of its insertion loss is controlled within ±0.5 dB, which helps to ensure that the signal light intensity changes little during long-term operation, and is suitable for applications such as medical imaging systems and military radars that require high signal consistency.

2. High return loss (low reflection)
The return loss (Return Loss) of the product can reach >55 dB (tested under single-mode fiber conditions), effectively reducing the potential interference of reflected light to lasers or detectors. This performance is crucial for light source protection in high-precision optical detection and communication systems, and can operate stably in high-precision instruments such as lidar and spectral analysis equipment.

3. 360° continuous rotation performance
The fiber optic slip ring supports 360° unlimited continuous rotation, and its rotation speed can reach up to 600 rpm while maintaining full load. During the rotation process, the slip ring realizes stable transmission of optical signals through high-precision bearings and optical alignment structures, effectively avoiding signal jitter caused by axial and radial shaking.

4. Excellent environmental adaptability
The product design takes into account the multiple requirements of complex application environments, has a wide operating temperature range (-40°C ~ +80°C), and can adapt to extremely cold or high temperature outdoor working conditions. In addition, its shell protection level can reach up to IP68 (customized model), which is suitable for high humidity, underwater or dusty environments, such as marine engineering, geological exploration, underwater robots and other fields.
