Practical help
Common problems
Exceeding minimum bend radius during installation
Ensure the cable is not bent tighter than 182 mm during the installation process to prevent fiber damage.
Improper storage temperature
Store the cable in a temperature-controlled environment before installation to ensure it meets the required installation temperature range of -30 °C.
Before use
- Verify the part number is 048TUC-T4190D20.
- Ensure the installation environment temperature is -30 °C.
- Confirm the conduit or aerial path can accommodate the 12.1 mm outer diameter.
- Check that the installation method complies with NEC Article 770 if installing indoors.
Specs in practice
- Corrugated steel tape armor
