Fiber Stretchers

1260-1650 nm; Delay Range >3 mm; RL >65 dB; Fiber Type SMF-28, Other; IL <0.2 dB; PDL <0.05 dBLunas 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.Key Features: Large Optical Path Delay Range: >3 mm (In Air)High SpeedLow Insertion Loss (IL): <0.2 dBAnalog and Digital ControlAnalog Input: 4 Channels, 4.7 V Maximum For Each ChannelDigital Input: 20-pin Connector, 12-bit TTL Control SignalOperating Wavelength: 1260 to 1620 nmMaximum Optical Power: 1,000 mWPhase Change Sensitivity: 810 π/VInternal Voltage Amplification: 30 V/VMaximum Voltage on Piezo: 140 VResonance Frequency: 2.2 ±0.3 kHzReturn Loss (RL): >65 dBPolarization Dependent Loss (PDL): <0.05 dBFiber Type: SMF-28, Other on Request Dimensions: 170 x 106 x 39 mmApplications: Sensors; Interferometers; Medical Imaging; Spectrum Analysis; OCT.

At the core of the PZ1 high-speed fiber stretchers is a fiber wound piezoelectric element for use in a wide range of optical interferometric measurement and sensing system applications. Optiphase’s expertise in the design, manufacture and use of all-fiber interferometers has produced a unique multi-layer winding approach resulting in an enhanced modulation function while maintaining a high operational frequency. PZ1 high-speed fiber stretchers are available with single mode (SM), commercial polarization maintaining (PM, Panda or Bowtie) or SM reduced cladding (RC) fiber types PZ1 high-speed fiber stretchers deliver a high performance to cost ratio, exceeding all other known competitive devices. The compact and low-profile form factor makes the PZ1 series easily configurable into small spaces. In addition, Optiphase fiber stretchers are unique in that they do not require proprietary drivers. For most low-voltage applications (<±15 V), Optiphase stretchers can be driven by standard electronics such as signal generators, op-amps or other laboratory equipment without modification. For more information on how to drive PZ1 high-speed fiber stretchers see the downloadable application note.
