The ETS Environmental Test System (v provides a fully integrated solution for long-term testing of optical devices. At the core of the ETS is the RLM Return Loss Meter for fast and accurate IL/RL measurements. The OSX switches used in the ETS have a repeatability of ± 0.005dB allowing for reliable long term measurements. With its capability to measure changes in insertion loss and mandrel-free return loss of up to 584 channels, the ETS is the perfect solution to perform compliance testing of devices being stressed in environmental simulations.

ETS Software has undergone extensive reliability testing to ensure system stability and data protection. ETS has been tested for 360 days continuous run time and has the ability to attempt recovery from measurement failures or dropouts.
