View system integration details
This page explains how Optical Transmission Medium is classified within Computer, Electronic and Optical Product Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
The material or structure within an opto-isolator that transmits optical signals between the input and output sides while maintaining electrical isolation.
Technical details and manufacturing context for Optical Transmission Medium
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Core Diameter | 50–1000 µm | Larger core for easier alignment, smaller for higher bandwidth |
| Numerical Aperture | 0.22–0.48 | Determines light acceptance angle and coupling efficiency |
| Attenuation | 0.2–3.0 dB/km | Lower for long-distance transmissionIEC 60793 |
| Bandwidth | 10–1000 MHz·km | Higher for high-speed data transmission |
| Operating Temperature | -40–85 °C | Outside range may cause material degradation |
| Storage Temperature | -55–105 °C | Wider range for non-operational storage |
| Relative Humidity | 5–95 % | Non-condensing; high humidity may affect optical surfaces |
| Tensile Strength | 50–200 N | Minimum for installation and handlingIEC 60794 |
| Minimum Bend Radius | 10–30 mm | Below this may cause increased attenuation or breakage |
| Refractive Index | 1.45–1.50 | Affects light propagation speed |
| Jacket Material | PVC, LSZH, PE | LSZH for fire safety, PE for outdoor |
| Weight | 5–50 kg/km | Depends on fiber count and jacket type |

Manufacturer profiles associated with Optical Transmission Medium.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
Common materials include optical-grade plastic, glass, and air gaps. The choice affects transmission efficiency, isolation voltage, and cost. Verify the specific material with the manufacturer for your application.
The medium is electrically non-conductive and physically separates the input and output circuits. Photons pass through, but electrical current cannot flow, ensuring high voltage isolation and noise immunity.
Key parameters include core diameter, numerical aperture, attenuation, bandwidth, operating temperature, and tensile strength. These are reference ranges; confirm exact values with the supplier for your model.
Failure can occur due to increased attenuation from contamination, physical damage like bending beyond the minimum radius, or material degradation from extreme temperatures or humidity. Regular inspection and adherence to environmental limits are recommended.
