About this app

Optical Splitter Calculator is a professional mobile tool built for fiber optic technicians, network engineers, and FTTH installers. Easily calculate optical attenuation, passive splitter ratios, and link budgets with precision.

KEY FEATURES

1. Optical Splitter Ratio Calculator
Calculate power distribution for unbalanced ratio splitters (FBT couplers) such as 1:2 (5/95 up to 50/50), 1:3, and custom multi-stage tapping.

2. PLC Splitter Loss Calculator
Accurate insertion loss calculation for standard symmetrical PLC splitters: 1:2, 1:4, 1:8, 1:16, 1:32, and 1:64.

3. Total Optical Link Budget
Calculate end-to-end cumulative attenuation, including connector loss, fusion splice loss, and fiber cable distance attenuation per kilometer.

4. Quick ODP & ONT Power Estimation
Estimate downstream optical power received at ODP distribution boxes and customer ONT/ONU modems to ensure compliant GPON/EPON signal margins (-8 dBm to -27 dBm).

5. Multi-Stage Cascade Simulation
Simulate multi-level cascaded splitters from OLT to drop cables without manual paper formulas.

DESIGNED FOR
- FTTH and OSP Field Technicians
- Fiber Splicers and Cable Contractors
- ISP Network Engineers and Maintenance Crews
- Telecom Students and Network Professionals

Eliminate calculation errors in the field. Optimize your fiber optic network deployment and maintenance with Optical Splitter Calculator.
