An Optical Loss Test Set is a hand held field instrument used to perform specific tests for a fiber optic link or channel. These tests include measuring the length and optical loss, and checking the polarity of the installed fiber optic links.
While many use an OLTS for basic troubleshooting tests of optical links and channels, the primary use is during the installation of fiber optic networks to certify the installation according to global industry standards (including TIA 568.3, ISO 11801, and ISO 14763-3). The required test information from these standards include measuring the length, optical loss, and polarity of the installed fiber optic links. Performing these tests are required by the customer and are referred to as "Basic Certification" or "Tier-1 Fiber Certification". To learn more visit: Tier 1 (Basic) Fiber Optic Certification.
