PRODUCT DESCRIPTION

The VIAVI OLTS-85 Optical Loss Test Set offers industry-leading speed, simplicity, and accuracy for Tier 1 fibre certification. Designed for technicians who need to certify fibre links quickly and correctly the first time, the OLTS-85 integrates optical loss measurement, length testing, polarity verification, and automated fibre inspection in one compact handheld device.

This test set supports singlemode, multimode, and quad fibre configurations (excluding PCM variants), making it ideal for a wide range of network environments—from enterprise cabling to hyperscale data centres. With built-in pass/fail analysis compliant with TIA/ISO/IEC standards and fast, one-touch certification, the OLTS-85 simplifies workflows and ensures confidence in your results.

Each test set can be operated from either the local or remote unit, eliminating the need for extra technicians or walking back and forth. Test results, inspection images, and cable IDs are stored onboard and can be managed using VIAVI J-Reporter software or integrated into cloud-based workflows with CERTiFi.

With all-day battery life, instant-on functionality, and compliance with best practices such as Encircled Flux and IEC 61300-3-35, the OLTS-85 is a complete solution for modern fibre certification.
