Optical systems with high-speed, lasers, analog (CATV), or amplifiers, Raman need high return loss for maximum performance. In addition, the optical return loss measurements can be used to prove that the installation was done with care and precision; for example, they can show that the optical connectors have been inspected and are clean. The ultra-sensitive power meter combined with a stabilized light sources to activate up to 70 dB measurement range.
