Fiber networks, mapped with confidence.
Eras Foundation Library builds EFL Telecom — modern, web-based GIS that lets any operator design, map, trace, and manage their fiber network with the precision the big incumbents charge a fortune for.
Our mission
Why we exist.
Reliable connectivity starts with knowing exactly where your network is — every strand, splice, and span. For too long, that level of insight has been locked behind expensive, complex, enterprise-only software. We're changing that: putting accurate, engineer-grade fiber GIS within reach of operators of every size, from regional carriers to municipal broadband and rural co-ops.
Our goals
What we're working toward, in the open.
Make fiber GIS accessible
Enterprise-grade mapping, signal tracing, and connection management — without the enterprise price tag or year-long rollout.
Accelerate broadband buildout
Help operators plan and deploy faster, so more communities get connected sooner.
Keep your data yours
Every company's network lives in its own isolated workspace. Clear ownership, clean export, no lock-in.
Earn trust through precision
RTK-grade coordinates, standards-based exports, and tooling fiber engineers actually want to use.
What we do
The platform, in a sentence each.
• Map your entire network — fiber, equipment, towers — on a live, shared map.
• Trace signal end-to-end with real optical link-budget math.
• Manage strands, splices, circuits, and contracts in one place.
• Collaborate with role-based access, team invites, and SSO.
• Export to GeoJSON, KMZ, CSV, or Shapefile anytime — your data, your formats.
Explore the platform
What EFL Telecom does for fiber engineering teams, one capability at a time.
Fiber network design
OSP/FTTH drawing with snapping, topology validation, and publish gating.
Strand management & splicing
TIA-598 tubes and strands, splice records, printable splice sheets.
Link budgets & tracing
Strand-level tracing through splices with PASS/FAIL margins in dB.
Cut analysis
Strands, services, circuits and contracts affected by any cable cut.
GIS import & export
Shapefile, GeoJSON, KMZ in and out — with mapping, dry runs, no lock-in.
Contract expiry mapping
Leases and IRUs linked to cables, five-tier expiry colors on the map.
