Polarization extinction ratio tester

CUBE-ER100 is a polarization extinction ratio (PER) measuring instrument based on a rotating polarizer, suitable for fiber optic and free space optical applications. Due to its compact size and fast measurement speed of up to 50 points per second, it can be easily integrated into polarization maintaining fiber automatic alignment systems.

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.
