Siemens SIPROTEC 5 Hardware Description

The attainable distance in multimode optical fibers is limited by 2 factors.
•
Bandwidth length product
Typical for 62.5 μm/125 μm optical fibers: 400 MHz x km to 800 MHz x km
Typical for 50 μm/125 μm optical fibers: 400 MHz x km to 1200 MHz x km
•
Fiber attenuation
The typical attenuation of a 62.5 μm/125 μm optical fiber is from 0.9 dB/km to 1 dB/km for light with the
wavelength λ = 1300 nm. 1.5 dB/km are added for splices, aging and as a reserve. An attenuation of
2.5 dB/km is used for calculation of the distance.
