Free browser-based tools for ISP and telecom NOC engineers. No login, no installation — all calculations run locally in your browser.
Look up fiber strand colors by number or find fiber numbers by color. Supports 12 to 288-fiber cables using TIA-598-C color coding standard.
Use Tool →Calculate total optical loss, power budget, link margin, and maximum fiber span for SMF and MMF links with connectors, splices, and MUX/DEMUX devices.
Use Tool →Calculate OTDR event and attenuation dead zones from pulse width. Get recommended launch cable length and a full dead zone reference table for all pulse widths.
Use Tool →Convert raw OTDR distance to actual ground distance by accounting for splice enclosure slack coils and route deviation. Improve fault location accuracy.
Use Tool →Full optical power budget for GPON, XGS-PON, and 10G-EPON networks. Supports single and two-stage splitting, connectors, splices, and safety margin.
Use Tool →Live countdown to SLA breach with real-time penalty exposure calculation. Supports 99.9%, 99.99%, 99.999%, and 4-hour MTTR SLA types.
Use Tool →Calculate total revenue exposure from a fiber outage across residential, SMB, and enterprise subscribers. Live counter grows every second the outage is open.
Use Tool →Generate professional outage notification templates for residential, SMB, and enterprise customers. Includes customer email, 160-char SMS, and formal SLA notification.
Use Tool →Upload an OTDR trace, enter cable route addresses — AI pinpoints the fiber break to within 500 feet on a satellite map with street view of the fault location. Built for ISP and carrier operations teams.
