Fiber & Optical tools
Optical link engineering: power budgets, splice and connector loss, GPON split ratios, dBm conversions, wavelength plans and transceiver references.
dBm / mW Converter
Convert optical and RF power between dBm, milliwatts, watts and dBW, with a reference scale of the levels you actually see on transceivers and radios.
GPON Splitter Calculator
Check a PON split design against the class budget: single or cascaded splitters, distance and connector count, with the per-subscriber bandwidth that split implies.
Optical Power Budget Calculator
Work out whether a fiber span will actually close: transmit power, fiber attenuation, splices, connectors and splitters against receiver sensitivity, with the remaining margin.
SFP / Transceiver Reference
Transceiver form factors, wavelengths, reach and typical transmit power, with the compatibility facts that decide whether a link comes up.
