Glasvezel-verliesbudget.
Bereken het verlies van een glasvezelverbinding uit lengte, connectoren, lassen en splitters en vergelijk het met het optische vermogensbudget.
An ideal 1:2 splitter costs about 3.5 dB, 1:8 about 10.5 dB, 1:32 about 17.5 dB.
- Total link loss
- 4.9 dB
- Fibre loss
- 3.5 dB
- Connectors, splices, other
- 1.4 dB
- Power budget (Tx min − Rx sensitivity)
- 14 dB
- Worst-case received power
- -10.9 dBm
- Maximum length with this budget
- 27.43 km

- TIA-568 allows up to 0.5 dB/km for single-mode, 1310 nm cabled fibre, 0.75 dB per connector pair and 0.3 dB per splice; the defaults are typical installed values.
- Take transmitter and receiver values from the transceiver datasheet. Certify the installed link with an optical loss test set (OLTS), and an OTDR to locate events.

Technische opmerkingen in het Engels
Loss budget only: dispersion and modal bandwidth limits are not calculated (see the multimode reach table). Everything is calculated in your browser; nothing is sent or probed on the network.
Loss = length × attenuation + connectors + splices + other. Budget = minimum transmit power − receiver sensitivity. The overload check uses maximum transmit power against the receiver’s maximum input.
10 km of single-mode at 1310 nm with 2 connector pairs and 4 splices loses 4.9 dB; a 14 dB budget leaves 6.1 dB after a 3 dB margin.
