Specifications of Optical Track Couplers
Optical track couplers are devices that transmit or split optical signals with high reliability, offering various coupling ratios, wavelength ranges, and mounting options for industrial and networking applications.
Overview
Optical track couplers are used to transmit or split light signals in industrial automation, storage systems, monorail conveyors, and fiber optic networks. They replace traditional cabling and slip rings, providing wear-free, bidirectional communication over distances up to 300 meters for industrial applications or in fiber optic networks for data distribution .
Key Specifications
1. Coupling Ratios and Types
- 1x2, 1x4, 1x8, 1x16, 1x32, 1x64 configurations are common for splitting signals .
- Coupling ratios vary, e.g., 50:50, 75:25, 90:10, 99:1 for multimode couplers .
- Singlemode couplers offer a range of coupling ratios with high directivity and low insertion loss . 2. Wavelength Range
- Multimode couplers: High-OH fiber operates from 400–900 nm, low-OH fiber from 400–2200 nm .
- Singlemode couplers: Dual-window versions for 1310 nm and 1550 nm, insensitive over an 80 nm range . 3. Power Handling
- Multimode couplers: Up to 2 W with connectors, 4 W when spliced . 4. Insertion Loss and Directivity
- Low insertion loss and high directivity are standard for both multimode and singlemode couplers, ensuring minimal signal degradation . 5. Connector and Mounting Options
- Connectors: FC/APC, SC/APC, LC/APC, MPO angled for minimal reflection .
- Mounting: ABS box, 19-inch rack, LGX box, or PC board mountable . 6. Environmental and Operational Features
- Stable over wide temperature ranges.
- Bidirectional operation for industrial data couplers.
- Wear-free optical technology ensures continuous operation with minimal downtime . 7. Fiber Types and Core Sizes
- Multimode: Ø50 µm core, step-index fibers .
- Singlemode: 250 µm coated fiber, 900 µm buffer tube, or 2.5 mm reinforced jacket for rugged use .
Applications
- Industrial automation: Automated guided vehicles, monorail conveyors, docking stations .
- Networking: Optical signal splitting in test equipment, telecom, and data distribution .
- Video and Ethernet transmission: Some optical data couplers support industrial Ethernet or video streams simultaneously . Optical track couplers provide flexible, reliable, and high-performance solutions for both industrial and fiber optic network applications, with specifications tailored to the required wavelength, power, and environmental conditions.
