Optical Loss Test Sets (OLTS) combine an optical light source and power meter to measure the end-to-end optical loss of a fiber optic link. OLTS solutions are widely used for fiber optic installation, network acceptance, link qualification, and Tier 1 fiber certification.
Compared with using separate power meters and light sources, an OLTS can provide a more integrated workflow for measuring insertion loss and verifying whether a fiber link meets predefined test limits.
3S Telecom offers handheld and automated OLTS solutions for single-mode and multimode fiber testing, with options for multiple wavelengths, duplex testing, data storage, pass/fail analysis, and test reporting, depending on the model.
For applications where the overall link loss must be verified and documented, an OLTS provides a practical solution for accurate end-to-end fiber loss testing.
OLTS vs OTDR
OLTS | OTDR |
Measures total link loss | Locates and characterizes events |
End-to-end measurement | Distance-based measurement |
Fiber certification | Fiber troubleshooting |
Tier 1 testing | Tier 2 / fault analysis |
Pass/Fail qualification | OTDR trace analysis |
