ZORA Cat5 Outdoor 25-pair Large Logarithmic Cable FAQ
Ideal for outdoor multi-channel voice transmission (e.g., telephone systems), low-speed data networks (e.g., 10BASE-T Ethernet), and security surveillance cabling. The 25-pair design allows simultaneous transmission of multiple signals (e.g., phone lines and camera/sensor connections).
Waterproofing: Seal connectors with waterproof tape or heat-shrink tubing to prevent moisture ingress.
Lightning Protection: Ground the cable shield using 4mm² copper wire.
Mechanical Protection: Install PVC/metal conduits in high-risk areas (e.g., under roads).
Twisted Pairs: Tightly twisted pairs reduce EMI.
Separation from Power Lines: Maintain at least 15cm distance from unshielded power cables
Yes, if:
Rodent-resistant jacket (e.g., PE/XLPE) is used.
Buried at least 60cm deep with a sand cushion layer.
Yes, but voltage drop must be considered. Limit PoE distance to 60m (12V) and ensure wire gauge meets standards (e.g., 24AWG).
