3.8.4 Connecting Single-Mode Fiber Optic
When using single-mode fiber cable, be sure to use single-mode fiber port
connectors. Single-mode fiber cable has a smaller diameter than multi-mode
fiber cable (9/125 microns for single-mode, 50/125 or 62.5/125 microns for
multi-mode where xx/xx are the diameters of the core and the core plus the
cladding respectively). Single-mode fiber allows full bandwidth at longer
distances, about 70km with the single-mode LC.
The same procedures as for single-mode fiber apply to multi-mode fiber
connectors. Follow the steps listed in Section 3.8.3 above.

Power Budget Calculations for CSG14 Series, Fiber Media
Receiver Sensitivity and Transmitter Power are the parameters necessary to
compute the power budget. To calculate the power budget of different fiber media
installations using Magnum products, the following equations should be used:
OPB (Optical Power Budget) = P
T
(min) - P
R
(min)
where P
T
= Transmitter Output Power, and P
R
= Receiver Sensitivity
