FST-001 Fiber Stretcher
Product information "FST-001 Fiber Stretcher"
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.
