A Twisted Pair cable is a cable with four cores
drilled in pairs.
The single cores have a diameter of 0.4 to 0.6mm.
This is a summary of the restrictions and rules referring to Twisted Pair:
•
Maximum number of coupler elements per segment 2
•
Maximum length of a segment 100m
•
What is the size of the area that must be served by the network?
•
How many network segments provide the best solution for the physical
(space, interference related) conditions encountered on site?
•
How many network stations (SPS, IPC, PC, transceiver, bridges if
required) must be connected to the cable?
•
What is the distance between the different stations on the network?
•
What is the expected ”growth rate” and the expected number of
connections that must be catered for by the system?
•
What is the expected data amount (Band width, accesses/sec.)?
•
Draw a diagram of the network. Identify every hardware item (i.e. station
cable, Hub, switch). Observe the applicable rules and restrictions.
•
Measure the distance between all components to ensure that the
maximum length is not exceeded.
