Table 3 Twisted Pair Cable Lengths per Cable Segment (2 of 3)
Table 4 Twisted Pair Cable Lengths per Cable Segment (3 of 3)
• Fiber Optic Circuits
The attenuation of cabling between two nodes/repeaters (fiber optic circuits are point-to-point)
must not exceed a 8 dB limit. If the distance required for a circuit segment is greater than
permitted, a Repeater module (RPT-F) must be inserted into the circuit at intervals less than, or
equal to, the 8 dB attenuation length restriction.
Attenuation Determination:
Find the rated dB loss per foot within the cable manufacturer's specifications. Determine the
total attenuation between the two nodes/repeaters due to the cable.
Loss = (loss/ft.) x (length in feet)
Establish the dB loss for each connector and splice. Sum all the losses.

NOTE: In the event of a panel failure at a wire node, the data is not regenerated locally. The node may be manually bypassed using the NBB-1
Assembly. In this case, the total length of wire becomes the sum of both lengths of wire between operating nodes. If the total length exceeds the
maximum allowable length for a given threshold, the network may lose communication. Separately powered repeater(s) may be employed at each
node in a point-to-point connection to ensure data regeneration.
