The JDSU OMK-36 is a professional optical loss test set (OLTS) designed for testing fibre optic installations, links, and networks. It combines the OLS-36 dual-wavelength laser source with the OLP-35 optical power meter to deliver a complete, portable solution for insertion loss measurement and optical power testing — suitable for both field deployment and laboratory use.

The OLS-36 laser source provides stable, calibrated output at standard test wavelengths for both single-mode and multimode fibre. The OLP-35 power meter offers accurate optical power readings across a wide dynamic range, making it well suited to network commissioning, maintenance, and fault diagnosis.

This kit is widely used by network engineers, fibre installers, and telecoms technicians for certifying and troubleshooting fibre optic links to industry standards.
