Fiber Loss Budget
Optical power budget: connectors, splices and distance vs. dB margin.
dBm / mW Converter
Convert power between dBm, mW, W and dBW, and compute link margin by subtracting losses.
Fiber Latency
Convert fiber distance to one-way and round-trip delay (~4.9 µs/km), comparing fiber vs vacuum.
DWDM / CWDM Grid
Optical channel planner: convert between frequency, wavelength and channel number on the ITU-T grid (DWDM 12.5–100 GHz and CWDM 20 nm).
Fiber Reach by Type
Show the maximum IEEE-standard distance by fiber type (OM1–OM5, OS1/OS2) and speed (1/10/25/40/100G).
Optical Rx Margin
Compare received power against the receiver sensitivity and overload: margin, dynamic range and overload warning.
