(H)PMCIR Fiber Optic Circulators

Benchtop Type; 1260-1650 nm; 4 Channels; Min. Retardation Range 2π; Fiber Type SM (9/125 µm); Connector Type FC/PC, FC/APC, SC/PC, SC/APC, LC/PC OZ Optics’ HSPC-1000 high-speed benchtop polarization controller/scrambler can control and/or scramble the polarization state of light passing through a fiber optic system. The HSPC-1000 generates four independent waveforms, operating at user-selectable frequencies, to generate different polarization states. It can also provide user-adjustable steady state signals to generate a particular polarization state. The HSPC-1000 contains four optical retardation elements that are used to produce any state of polarization. Each of these elements is controlled by an electrical signal, generated by an internal piezoelectric element in the device driver. The driver produces the appropriate drive signals: four independent signals that can be directly controlled by the HSPC-1000 high-speed benchtop polarization controller/scrambler.

1260-1650 nm; Delay Range >3 mm; RL >65 dB; Fiber Type SMF-28, Other; IL <0.2 dB; PDL <0.05 dB General Photonics’ FST-001 is a piezo-driven fiber stretcher with an optical delay range of up to 3 mm. The device, including the piezo driver, is packaged in a metal enclosure. Each of the FST-001 fiber stretcher’s four piezos can be controlled independently, allowing high resolution or large stroke. Piezos can be controlled with an analog signal or a 12-bit TTL signal. Under analog control, the driving circuit acts as a 4-channel voltage amplifier with 30V/V amplification. Alternatively, the output voltage can be controlled by a computer equipped with a digital I/O card, or by a microprocessor.
