Why This Matters
Fiber Planning Done Right
A failed fiber link means signal loss, downtime, and costly rework. Plan your runs correctly the first time.
Know Your Limits
Single-mode and multi-mode fiber have vastly different reach. Our calculator accounts for fiber type, speed, and real-world losses.
Budget Every Decibel
Connectors, splices, and cable length all consume link budget. See exactly how much margin you have before signal degrades.
Spec with Confidence
Get the right transceiver and fiber combination for your inter-building or campus backbone links on the first try.
