Question:
Is the use of caution tape a requirement when trenching a fiber optic cable and placing it in HDPE conduit?
Yvette Harrison
A
Answer:
Hey Yvette thanks for your question. No, but it might be a very good idea to install one. There are separation rules from other conductors for underground optical fiber cable as stated in 770.47. Directly buried service conductors must have a warning ribbon as stated in 300.5(D)(3) but that does not apply to fiber optic cables.
