The physical location of the doublers is driven by the following three
deployment rules:
1 Place the enclosures at the electrical limits (35 dB) of each span. This
places the first doubler at the 35 dB location and the second at 70 dB and
so on. This allows the maximum circuit range to be realized.
Caution must be observed when pushing doubler spans to
their 35 dB maximum range. Refer to ADC's Technical
Advisory #TA-015 on HiGain operating ranges and general
deployment guidelines.
2 If Rule 1 is not applicable, try to make all spans the same electrical length
(same 196 kHz loss). This minimizes the maximum span loss and assures
maximum operating margin, resulting in optimal transmission
performance on the HDSL cable pairs. If specific application constraints
preclude using rule 2 or, if two different circuit layout choices have the
same maximum span loss, then use Rule 3.
