Condition: Used

The JDSU OMK-35P Optical Loss Test Set consists of the OLS-36 Optical Laser Source (2303/11) and OLP-35 Optical Power Meter (2302/12). This is a professional-grade fibre optic loss measurement kit used for characterising insertion loss on both single-mode and multimode optical networks. Multiple units are in stock.

Included in the sale:
• JDSU OLS-36 Optical Laser Source (2303/11)
• JDSU OLP-35 Optical Power Meter (2302/12)

Please note that we have multiple units in stock, and the images presented are of one of them, therefore the cosmetic condition of the exact item you will receive may slightly differ.

The JDSU OMK-35P is an optical loss measurement kit (OLTS) designed for testing fibre optic installations and links. Combining the OLS-36 dual-wavelength laser source with the OLP-35 optical power meter, the kit provides a complete solution for insertion loss and optical power measurement in the field or laboratory.

The OLS-36 laser source delivers stable, calibrated output at standard test wavelengths, while the OLP-35 power meter provides accurate power readings across a broad dynamic range. Together they form a reliable and portable OLTS solution commonly used by network engineers, installers, and telecoms technicians.
