{"uid":"cap_5cLCI0a4PMD5S0L8w1EUO","slug":"chromatic-dispersion-calculator-0021e8e1","name":"Chromatic Dispersion Calculator","description":"Fiber optic chromatic dispersion calculator. Computes dispersion coefficient D(λ) in ps/(nm·km), accumulated dispersion (ps/nm) over a fiber span, and dispersion slope for SMF-28, NZDSF, DSF, LEAF, DCF, and ULLSF fiber types. Optionally sweeps a wavelength range (C-band, L-band, or custom). Pure math — instant, zero API calls. Useful for optical network design, DWDM link budget, and dispersion compensation planning.","url":"https://the-stall.intuitek.ai/cap/chromatic-dispersion","method":"GET","headers":{},"bodySchema":{"type":"object","properties":{"properties":{"type":"string"}}},"responseSchema":null,"example":{"request":{"properties":"silica_glass_singlemode_fiber"},"response":{"D_slope":0.0584,"aeff_um2":80,"fiber_name":"SMF-28 (G.652D)","fiber_type":"smf28","generated_at":"2026-06-12T04:30:54.443Z","D_coefficient":17.3493,"wavelength_nm":1550,"attenuation_dB":16,"fiber_length_km":80,"accumulated_dispersion_ps_nm":1387.944,"zero_dispersion_wavelength_nm":1312}},"exampleRequest":{"properties":"silica_glass_singlemode_fiber"},"tags":["x402"],"displayCostAmount":"0.034","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"settled","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.034/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.034","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.034","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_4ZIVVIydvq6M1SaRzsr-y","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.034","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Calculates chromatic dispersion properties for optical or material systems given input parameters","exampleAgentPrompt":"What's the chromatic dispersion for a standard single-mode optical fiber with properties typical of silica glass — give me the dispersion coefficient and how the spectrum spreads?","exampleUseCases":null,"resultDescription":"Returns chromatic dispersion values including dispersion coefficients and spectral properties for the given material or optical system, helping quantify how different wavelengths propagate at different speeds through the medium.","failureModes":["Invalid or missing properties parameter returns an error","Malformed JSON input schema causes a 400 error","Payment not received results in 402 Payment Required response","Properties outside supported material domain may return null or incomplete dispersion values"],"whenToPreferThis":"Use this endpoint when you need to compute chromatic dispersion for optical or photonic systems and want a pay-per-call model with no API key setup.
