GENERIC INFORMATION

This section provides generic information for both the HiGain and PG-Flex applications.

DOUBLER ENCLOSURE CAPACITIES WITH FULL SOLAR LOAD

The physical location of the doublers is driven by the following three deployment rules:

1Place 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.

2If 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.
