EPC Electrically Driven Fiber Polarization Controllers/Scramblers

980-1620 nm; SOP Change Rate >360 krad/s; IL <0.6 dB; PDL <0.1 dB; PMD <0.2 ps; AL <0.1 dB; RL >50 dB General Photonics’ MPC-202 advanced multifunction polarization controller is specially designed to meet the requirements of coherent receiver performance tests. MPC-202 combines General Photonics’ award winning PolaRite™ II/III polarization controller with proprietary polarization control algorithms to achieve a wide range of polarization control functionalities, including high-speed quasi-uniform rate polarization scrambling, random-rate polarization scrambling with Rayleigh rate distribution, discrete-state polarization scrambling with high slew rate, sine, square, and triangle-wave SOP (state of polarization) modulation, and manual polarization control functions. In particular, the “Tornado” quasi-uniform rate polarization scrambling function can achieve a high SOP scrambling rate of up to 60,000 revolutions/s (more than 360 krad/s) with a narrow rate distribution clustered around the highest rate. In short, the MPC-202 is an ideal tool for production or laboratory testing of polarization related functions and parameters, including passive/active component characterization, performance tests of fiber optic interferometers, sensor systems, RF photonics systems, etc. The quasi-uniform rate high-speed scrambling function is particularly useful for SOP tracking speed testing of coherent receivers, and the square wave SOP modulation function is ideal for SOP recovery time tests.

840-1650 nm; Delay Range 0-1,200 ps; RL 50 dB; Fiber Type SMF-28, HI780, HI1060, PM Panda; IL 1.0, 1.5 dB; PDL 0.1 dB The General Photonics VDL-001 module is a manually controlled variable fiber optic optical delay line. Multiple versions are available with path length of up to 1,200 ps. A low insertion loss and low variation of insertion loss is critical for most applications, and the VDL-001 has less than ±1 dB variation even up to 1,200 ps. The delay line is packaged in a small aluminum box to prevent dust or noxious vapors from contaminating the optical path. The compact, rugged design makes the VDL-001 device ideal for integration in network equipment, test instruments, and optical coherence tomography (OCT) systems for precision optical path length or timing alignment.
