Frequently Asked Questions

Does Cat5e underwater cable support Power over Ethernet (PoE)?

Yes. The 4-pair Cat5e construction supports IEEE 802.3af (PoE, 15.4W) and 802.3at (PoE+, 30W) standards when conductor cross-section allows. Specify your PoE requirement when ordering, as conductor size may need to be upgraded for high PoE power delivery over long runs.

Is this cable halogen-free?

The standard PUR jacket is low-smoke halogen-free (LSZH) compatible. We can also supply a LSZH outer jacket variant for applications where smoke toxicity is a concern (e.g. saturation diving systems, enclosed offshore modules).
