T-Tapping allows an installer to run data with less wire. T-Tapping Popit loops is not recommended, although is allowed provided t-tapping rules are followed.
Distance Requirements for Popit Data Loops:
Wire Gauge
Distance
22 AWG (0.8 mm)
1800 ft (549 m)
20 AWG (1.0 mm)
2890 ft (881 m)
18 AWG (1.2 mm)
4600 ft (1402 m)
16 AWG (1.5 mm)
7320 ft (2231 m)
14 AWG (1.8 mm)
11650 ft (3551 m)
Data distance requirements must be followed.
Calculate additional data distance for each T-tap as follows: add the length of the T-tap, plus the distance from the point of the T-tap back to the data source. For example, a 100 ft T-tap 800 ft from the POPEX adds 900 ft in data distance.
Never extend a single T-tap more than 200 ft from the main data bus.
Never T-tap off another T-tap.
T-taps, if used, should originate from a pair of wire terminals located in a junction box to facilitate troubleshooting.
