The Siecor OTS-300 is a handheld optical test set for field testing and troubleshooting of fiber optic networks. It combines optical power meter and light source in a single instrument, enabling dual-wavelength attenuation measurements across multimode and single-mode fiber applications. The device supports installation, qualification, and maintenance operations in LAN, telephony, and CATV environments.
