Polarization extinction ratio tester

It has a full speed USB 2.0 port for remote control, a UART port for interconnection between different CUBEs, two analog outputs for closed-loop control of PM fiber optic automatic alignment system, and two universal TTL inputs/outputs for measurement and control synchronization. CUBE-ER100 can be used in conjunction with polarization maximizing cube CUBE-PM100 to perform fast and accurate PER and angle measurements on PM fiber reels, coils, and components without splicing inline polarizers and PM connectors.
