E-TEK FPCR-1B programmable polarization controller driver

The E-TEK FPCR-1B is a programmable electro-optic polarization controller driver that manipulates light polarization in fiber optic systems. It delivers high-speed response and operates in three distinct modes: manual control for direct parameter adjustment, polarization tracking for maintaining desired states against environmental drift, and polarization scanning for systematic characterization. Remote programming via GPIB (IEEE-488) and RS232 interfaces, combined with analog control inputs, enables integration into automated test environments and coherent communication systems.
