The symbols x1, x2, x3and x4 denote output power split percentages.
Split percentages are always listed in decreasing order (highest
percentage first). The possible split percentages correspond to the
following codes:
Split percentage Symbol
5% 1
10% 2
15% 3
20% 4
25% 5
30% 6
35% 7
40% 8
45% 9
Example: Module with SC/APC connectors and output split
percentages of 45%, 5%, 30% and 20% would have the model
number:
HLS 1204-AS-9164-1
