A Two-Way Optical Loss Test Set (OLTS) designed for medium to ultra-high fiber count certification and troubleshooting. It performs loss, length, and optical return loss (ORL) testing on single-mode fiber at 1310, 1490, and 1550 nm. A pair of these compact instruments deliver superior productivity, accuracy, and ease of use. Features an APC (Angled Physical Contact) connector with an 8° angle for optimized return loss performance.

A pair of these compact instruments deliver superior productivity, accuracy, and ease of use. Features an APC (Angled Physical Contact) connector with an 8° angle for optimized return loss performance.
Each SM fiber needs just one test hook-up and one key press for a complete 2 W and bidirectional loss, length, and ORL test, eliminating administration, training, and test errors. Testing is accurate and can take only 5 seconds, directly onto flexible standards-compliant Tier 1 certification reports.
A pair of instruments both display length, bi-directional loss, and ORL fiber testing at each end, in real time, with no need to specify master/slave instruments. A single instrument can also be used as a stand-alone ultra-stable light source and power meter, VFL, ORL meter, or tone generator/detector.
Features a stand-alone Visual Fault Locator (VFL) at 650 nm for fault location and continuity checking, independent of the Autotest function.
Equipped with APC connectors (8° angled endface) to ensure full ORL sensitivity for installed single-mode fiber testing.
