FST-001 Fiber Stretcher

840-1650 nm; Delay Range 0-1,120 ps; RL 50 dB; Fiber Type SMF-28, HI1060, HI780, PM Panda, PM 980 Panda; IL 1.0, 1.5 dB; PDL 0.1, 0.2 dBLunas MDL-002 family of motorized variable fiber optic optical delay lines allow optical path length adjustment of up to 560 ps in a single pass. Driven by a DC motor with an integrated encoder, the MDL-002 has a delay resolution of less than 0.3µm (1 fs).In addition, its advanced motion design guarantees longevity for long-term continuous operation. Low insertion loss and high reliability make this device ideal for integration in optical coherence tomography (OCT) systems, network equipment and test instruments for precision optical path length control or timing alignment.Three configurations of the MDL-002 fiber optic delay line series are available:Integrated unit for use as a bench-top instrument for laboratory applicationsTwo-piece unit with the optical head and control unit separated for installation into customer equipmentOEM version with a miniature controller boardAll three versions can be remote controlled by a PC or a micro-processor through an RS-232 interface. The delay line is available with either single mode (SM) or polarization maintaining (PM) fiber pigtails.Key Features:High Optical Delay Resolution: 0.3 µm / 1 fs, 0.6 µm / 2 fs Per Encoder CountLow BacklashLow Insertion Loss (IL): 1.0, 1.5 dB TypicalInsertion Loss Variation: ±0.3, ±0.5, ±0.7 dB Over EntireHigh Delay-to-Length RatioOptical Delay Range: 0 to 330, 0 to 560, 0 to 1,120 psOperating Wavelength: 840 to 1650 nmPosition Accuracy: ±3, ±6 µmPosition Repeatability: ±3, ±6 µmPolarization Dependent Loss (PDL): 0.1, 0.2 dB MaximumReturn Loss (RL): 50 dBExtinction Ratio: >18 dB (For PM Model)Optical Power Damage Threshold: 300 mWControl Mode: Panel Keypad and RS-232 InterfaceFiber Type: SMF-28, HI1060, HI780, PM Panda, PM 980 PandaDimensions: 178 x 102 x 41, 229 x 112 x 41 mm (Integrated Unit), 65 x 65 x 21.5 mm (Mini Controller Board), 132/157 x 37 x 18 mm (Optical Head)Applications: Optical Coherence Tomography (OCT) Systems; Scientific Instrument Control; Network Optical Path Length Control or Timing Alignment; Optical Fourier Spectrum Analysis; Optical Interferometry; Delay Generation and Measurement; Optical Time Division Multiplexing (OTDM); Fiber Sensors

Varies Delay Between Polarization States; Delay Range ±50 ps; Delay Resolution 0.0027 ps; Return Loss -40, -50, -60 dB; Max. Insertion Loss 1.2 dB OZ Optics’ DDL-650-11 differential polarization delay lines represent the next stage in controlling polarization mode dispersion in optical networks. The devices split the light within a fiber into orthogonal polarizations, and then actively vary the time that one polarization travels compared to the other polarization before combining the two polarizations together again. With this technique, one can introduce up to ±50 ps of optical delay in a system. The resolution of the DDL-650-11 differential polarization delay lines is better than 0.003 ps, thus providing a high degree of control. The devices are easily controlled by a computer via an RS-232 interface. Home and end position sensors allow easy monitoring of the device status and prevent any potential damage to the device.
