DDL-650-11 Differential Polarization Delay Lines

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 dBThe Luna 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.Key Features:Highest Delay-to-Length RatioOptical Delay: Up to 1,200 psInsertion Loss (IL): 1.0, 1.5 dB TypicalLow Insertion Loss Variation: ±0.3, ±0.5, ±0.7 dBOperating Wavelengths: 840, 1060, 1310, 1550, 1260 to 1650 nmOptical Delay Range: 0 to 330, 0 to 600, 0 to 1200 psReadout Scale Resolution: 0.05 mmPolarization Dependent Loss (PDL): 0.1 dB (SM Model)Return Loss (RL): 50 dBExtinction Ratio: >18 dB (PM Model)Optical Power Damage Threshold: 300 mWFiber Type: SMF-28, HI780, HI1060, PM PandaDimensions: 25.5 x 53 x 107/152 mmApplications: Optical Coherence Tomography (OCT) Systems; Passive Time Division Multiplexing (TDM); TDM Bit Alignment; Fiber Interferometers

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
