The Viavi Solutions (formerly JDSU) OLS-36 is a handheld, battery-operated quad optical laser source designed for fibre optic network installation, maintenance, and acceptance testing. It is commonly paired with an optical power meter to form an Optical Loss Test Set (OLTS) for measurements in compliance with industry standards such as TIA-526 and ISO/IEC 14763-3.
The OLS-36 supports four wavelengths in a single compact instrument, covering both singlemode and multimode fibre types, making it an efficient all-in-one solution for field technicians.
Key Specifications:
Wavelengths (Multimode): 850 nm and 1300 nm
Wavelengths (Singlemode): 1310 nm and 1550 nm
Fibre Types Supported: Singlemode (SM) and Multimode (MM)
Connector Interface: SC-PC (standard); FC also supported depending on adapter configuration
Output Stability: High stability laser output suitable for insertion loss testing
Power Source: Battery operated for portable field use
Compliance: Supports TIA-526-14A and ISO/IEC 14763-3 test methods
The OLS-36 is part of the Viavi SmartClass Fibre family of handheld test tools, widely used by telecommunications engineers, network contractors, and data centre technicians worldwide.
