About this app

Optical Fibre Toolkit is the one stop solution for optical fibre engineers. Every tool is designed for real-world use on the job site.

The tools include:
- Fibre Colour Codes — TIA-598-D lookup. Find colour by number or number by colour. Supports 2, 4, 6, 8, and 12 fibres per tube.
- Link Budget Calculator — Total fibre link loss with connector, splice and attenuation values. Power margin check included.
- PON Splitter Calculator — FTTH and GPON power budget with cascaded splitter stages. Supports 1:2 through 1:128.
- Power Conversions — dBm to mW, mW to dBm, dB to percentage, and percentage to dB. Supports positive (gain) and negative (loss) values.
- Splice Loss Reference — Filterable table by fibre type (SM, MM, OM1 to OM5) and method (fusion, mechanical, connector).
- Connector Reference — LC, SC, FC, ST, and MPO specifications with polish types (UPC, APC, PC) and mating compatibility.
- Bend Radius Guide — Minimum bend radius by fibre type including G.652, G.657A, G.657B, and OM1 to OM5.
- Cable Pull Tension — Conduit pull force calculator with friction coefficient and bend multiplier. Pass or fail against rated maximum.
- Fibre Latency — Signal propagation delay with configurable refractive index. One-way and round-trip time.
- Fibre Characteristics — Numerical Aperture, Critical Angle, and Acceptance Angle from core and cladding indices.
- Wavelength to Frequency — Nanometres to terahertz and terahertz to nanometres converter.
- ITU Wavelength Grid — Full DWDM C-Band (C17 to C61, 100 GHz spacing) and CWDM (18 channels) reference tables.
- Chromatic Dispersion — Sellmeier approximation for pulse spread over distance.
- OSNR Calculator — Signal quality for amplified WDM spans.
- EDFA Calculator — Amplifier gain and total output power for WDM channels.
- Span Distance — GPS coordinate to kilometre distance with cable route estimate.
