Figure 2-39 shows the same dual-channel system, but using a combination of 62.5/125 m
duplex fiber-optic media and twisted, shielded, low-capacitance wiring.
Use ST connectors to attach the fiber-optic media to the OCCs.

Connect wires for shields
to ground screw in upper-
left-hand corner of NIC
Installation Notes: 1. Do not T-Tap the network fiber. Use daisy-chained interconnections.
2. Daisy chain fiber back from Node N to Node 1.
3. Use twisted, shielded wire for NIC - OCC and NIC - NIC interconnections.

Leave shield wire floating at Node 3. Do not connect wire for
shield to the earth-ground screw in upper-left-hand
corner of last NIC. Trim shield wire as much as possible.
