figure 2.4: Example with cable lengths

Point I

The maximum available power with 240 m of extension cables is 19 W (refer to figure 2.3). Because the first and second trunk splitter use 2.6 W, the available power at point I is 19 - 2.6 = 16.4 W.

Point II

The maximum available power with 240 m of extension cable is 25 W (refer to figure 2.3). Because the first and second trunk splitter use 2.6 W, the available power at point II is 25 - 2.6 = 22.4 W.
