Key Considerations

1. Temperature Rating: Ensure the connector is rated for the expected low-temperature range. For extreme cold, connectors like GwliUni SC (-40℃ to 75℃) are ideal.
2. Fiber Type Compatibility: Verify whether the connector supports single-mode or multimode fibers.
3. Termination Method: Choose between field-installable, pre-polished, or splice-on connectors depending on installation requirements.
4. Durability: Look for connectors with robust materials such as PEI or ceramic ferrules to withstand mechanical stress and environmental conditions. By selecting connectors with the appropriate temperature rating and material durability, you can ensure reliable fiber optic performance in low-temperature environments.
