Open a calculator, identifier, conversion tool, or color reference without switching categories first.
Optical Splitter Loss Calculator
Enter output ports and excess loss → ideal and total insertion loss for PLC and FBT splitters.
Open toolFiber Link Loss Budget Calculator
Fiber attenuation, connectors, splices, splitter, Tx power, and Rx sensitivity → end-to-end system margin.
Open toolFiber Color Chart (TIA-598)
Fiber, buffer tube, or ribbon position → TIA-598 base and tracer color, with reverse color lookup.
Open toolFiber Connector Identifier
Select a connector image → ferrule and coupling specifications, standards, and application scenarios.
Open toolOptical Unit Converter
dBm ↔ mW, dB loss or gain, and µm / nm / km conversions in one place.
Open toolFiber DB Loss Calculator
Fiber type + wavelength + distance → expected fiber loss, or reverse a loss allowance into maximum distance.
