3.4 Ethernet Cabling

To ensure proper operation when installing chassis in a network, make sure that the
cables are suitable for 100/1000 fiber-optic or 10/100/1000BASE-T copper
operation, as appropriate. Ensure that the installation complies with the following
guidelines:
Issue: 01
• Cable type: shielded twisted pair (STP) cables; Category 3 or better for
10BASE-T, Category 5 or better for 100BASE-TX, and Category 5, 5e or 6 for
1000BASE-T.
• Make sure that the cables are not damaged and that the connectors are
connected securely.
• For inter-building connections use fiber-optic cables.
• Copper ports are suitable for connection to intra-building or unexposed wiring or
cabling, and are intended for indoor applications only. The intra-building ports of
the equipment must not be metallically connected to interfaces that connect to
the OSP or its wiring. These interfaces are designed for use as intra-building
interfaces only and require isolation from the exposed OSP cabling. The addition
of Primary Protectors is not sufficient protection in order to connect these
interfaces metallically to OSP wiring.
• Avoid installing copper cables close to strong electromagnetic fields generated
by electric generators, elevator engines, or other similar heavy electric
machines.
• Make sure you only use SFPs that are supported by Nokia.
