This fiber loss calculator can estimate the total fiber link loss through a particular fiber optic link if the fiber length, the number of splices and number of connectors are known. This calculation is simply the sum of all worst-case loss variables in the link.
Link Loss = [fiber length loss] + [splice loss] + [connector loss] + [safety margin]
| Fiber Type | Wavelength | Fiber attenuation / km* | Fiber attenuation / km # | Connector Loss | Splice Loss |
|---|---|---|---|---|---|
| Multimode 50/150µm | 850 nm 1300 nm |
3.5 dB 1.5 dB |
2.5 dB 0.8 dB |
0.75 dB | 0.1 dB |
| Multimode 62.5/125µm | 850 nm 1300 nm |
3.5 dB 1.5 dB |
3.0 dB 0.7 dB |
0.75 dB | 0.1 dB |
| Single Mode 9µm | 1310 nm | 0.4 dB | 0.35 dB | 0.75 dB | 0.1 dB |
| Single Mode 9µm | 1550 nm | 0.3 dB | 0.22 dB | 0.75 dB | 0.1 dB |
