Optical Path Engineering

👥 Who We Are

Optical Path Engineering was founded by a fiber optic network engineer with hands-on experience designing, building, and troubleshooting real networks. Every tool we build comes from a genuine need encountered in the field — not a product roadmap meeting.

We build software that engineers actually want to use: fast, technically accurate, free where it can be free, and priced fairly where it can't. We don't build for press releases or investor decks. We build for the technician on a ladder at 2am trying to find a cut cable.

📏 What the Calculator Covers

The Optical Path Calculator handles every significant loss source in a real fiber-optic link:

• Fiber attenuation — SMF and MMF (OM3/OM4/OM5) at 850, 1310, and 1550 nm with adjustable dB/km values
• Connector insertion loss — LC, SC, FC, and MPO terminations
• Fusion and mechanical splice loss across any number of splice points
• Patch panel insertion loss for structured cabling and IDF/MDF environments
• MUX/DEMUX insertion loss — CWDM (4–16 ch) and DWDM (16–96 ch) passive multiplexers
• Full power budget with configurable Tx power, Rx sensitivity, and safety margin
• Maximum span estimator for any transceiver and fixed overhead loss

All calculations run entirely in your browser. No data is ever transmitted to a server, no account is required, and the tool functions offline once loaded.

  Optical Path Fault Locator

  AI-powered fiber fault location. OTDR trace analysis + road-snapped route geometry + Claude AI = a GPS coordinate and satellite map view of the break, plus a ticket-scoped map/trace view shared across NOC, OSP, and ISP teams. Targeting ISP and carrier operations teams. Launching at opticalpathengineering.com.

  ISP Hub Utilization Engine

  Auto-calculates power draw, HVAC load, generator runtime, and DC-plant capacity for a hub facility directly from what's installed — racks, devices, and load data in, a live utilization picture out. Replaces the manual spreadsheet audit most ISPs run today.
• ▶
  In Development

  ISP Documentation & Circuit Tracing

  Hub, rack, device, and port documentation with MUX/preterm chassis support, plus circuit tracing from device to customer. A full inside-plant records layer for ISPs and CLECs who need more than a spreadsheet but less than a $50k enterprise GIS platform.

  Fiber Route Database Integration

  Import your GIS data (GeoJSON, KML, or CSV) to enable route-accurate fault location instead of straight-line estimation. Walk the actual cable path to the fault with sub-100-foot accuracy.

  Satellite & Street View Fault Visualization

  After fault location, display a satellite image and street view of the exact fault coordinate. Claude AI analyzes the imagery for pole infrastructure, conduit markers, and aerial fiber indicators.
