Notes:
1
Hybrids are shipped with the following defaults:
• All empty chassis slots already have blank rear cover plates installed automatically & are included in the price of the chassis.
Additional spare blank rear cover plates must be purchased separately.
• Viewed from the front, hybrids are inserted into the chassis from left to right. Balanced hybrids first, then followed by any skewed
hybrids.
• Viewed from the front, optional boards are inserted from right to left, with the TS board in the right-most position(s).
2
Max number of boards in a chassis is 4. So the total number of Balanced (B) + Skewed (S) + Optional Boards can not exceed 4.
For example, HYB1RU-FM-B3-S2-N is an invalid number because it calls for 5 hybrids total (B3, S2).
3
Balanced combiner includes interconnecting cables and requires position 3, of the catalog number, to be "B4". This option is for
redundancy in phase-to-phase coupling schemes.
4
Position 6 is only used when an optional board is present. Otherwise this catalog number position is blank. There can be more than
one type of optional board and thus multiple suffix codes.
