Fiber Optic Slip Ring: Basic Information and Product Parameters Determining Pricing
Working principle, technical parameters and price influencing factors
I. Basic Knowledge: Core Concepts and Unit Conversions
(1) Core Definitions
Fiber optic slip ring (also known as fiber optic rotary connector or optical combiner ring) is a precision device that uses optical fibers as the data transmission medium to enable uninterrupted optical signal transmission between rotating and stationary components. It can be used independently or combined with an electrical slip ring to form a "hybrid opto-electrical slip ring," suitable for scenarios requiring 360° rotation and stable signal transmission (e.g., winches, tethered drones, opto-electrical pods, pan-tilt units, etc.).
(2) Key Prior Knowledge-Length Unit Conversion
To comprehend the core principles of fiber dimensions, one must master the microscopic length relationships (fiber cores typically measure in micrometers):
1.1 meter (m) =10 decimeters (dm) =100 centimeters (cm) =1000 millimeters (mm)
2.1 millimeter (mm) =1000 micrometers (μm) = 10^6 nanometers (nm) (i.e., 1 μm = 10^-6 m, 1 nm = 10^-9 m)
3.Key correlations: The single-mode fiber has a spot diameter of 9μm, while multi-mode fibers exhibit various spot diameters such as 50μm and 62.5μm. The cladding layer diameter is 125μm (equivalent to 0.125mm, approximately 1/5 the diameter of a human hair), requiring unit conversion to comprehend its precision.
(3) Definition at Room Temperature
Performance parameters of optical fiber slip rings (e.g., insertion loss) are typically labeled with 'room temperature' specifications, as defined by industry standards.
1.Normal range: 10~40℃ (laboratory standard environment, civilian products)
2.Wide range: -20°C to +80°C (Industrial grade)
3.Military-grade standard: -40℃3 to +65°C (product testing and factory calibration benchmark)
4.Note: For temperatures exceeding 10-40°C, consult the 'Full Temperature Performance' section, which serves as a key criterion to differentiate civilian, industrial, and military-grade products.
