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.
