ODL Fiber Optic Delay Lines

840-1650 nm; Delay Range 0-130 ps (4 cm); RL 55 dB; Fiber Type SMF-28, HI780, HI1060, PM Panda; IL <0.8 dB; PDL 0.1 dBLunas’ VDL-004 module is a miniature variable optical delay line designed specifically for OEM applications. This device offers continuous control with high precision, zero backlash, and good thermal stability.An internal mirror can be installed to cause light to double pass the device, doubling the delay range. A locking mechanism is provided for locking the delay at a permanent position. The VDL-004 delay line module generally comes with single mode (SM) or polarization maintaining (PM) fiber pigtails per customer requirement.With a footprint of only 78 x 22 x 15 mm for a delay range of 130 ps (40 mm), the device can be easily integrated into larger instruments or assemblies for precision optical path length control or timing alignment. Convenient mounting brackets allow mounting in any orientation, as well as easy integration of multiple units on a base plate to form an array.Key Features:Compact Size: 78 x 22 x 15 mmContinuous AdjustmentZero BacklashLow Insertion Loss: <0.8 dBInsertion Loss Variation: <0.4 dB Over Entire RangeHigh StabilityFlexible Mounting OptionsPosition Locking IncludedOperating Wavelength: 840, 1060, 1310, 1550, 1260 to 1650 nmOptical Delay Range: 0 to 130 ps (40 mm) ContinuousOptical Delay Resolution: 3.34 ps (1 mm) Per Full TurnDelay Repeatability: <20 µmZero Point Delay Offset: 230 psPolarization Dependent Loss (PDL): 0.1 dB (SM Fiber)Return Loss (RL): 55 dBPolarization Extinction Ratio: 20 dB (PM Model)Optical Power Damage Threshold: 300 mWFiber Type: SMF-28, HI780, HI1060, PM PandaApplications: Microwave Photonics; Phased Array Antennas; Coherent Detection Systems; Optical Time Division Multiplexing (OTDM); Optical Coherence Tomography (OCT); Optical Interferometry; Optical Fourier Spectrum Analysis; Fiber Sensors

 Fiber Coupled, Ultra-stable; 375 to 2000 nm; Wavelength Stability (typ) ±0.2 nm; Output Power 0.5 to 300 mW; Power Stability <0.1% to <2%; Polarization Extinction Ratio >18 to >23 dB; Fiber Type SM, MM or PM The OZ-1000, OZ-2000 and OZ-3000 fiber pigtailed ultra-stable laser module series are temperature stabilized, fiber coupled, laser delivery systems. The compact housing contains both the laser and the temperature control. Powered by a single 5 V DC supply, the low noise laser diode and TEC drivers maintain the wavelength variation to better than 0.2 nm, and also reduce the tendency of the laser diode to mode hop, assuming there is no feedback into the laser cavity. The electrical interface on the OZ-1000 is located on the front face of the unit alongside the optical interface, while on the OZ-2000 and OZ-3000 it is on the rear of the unit. The three configurations have as default analog CW output power control, with analog modulation capability. A TTL input interface is optional. Our low profile OZ-3000 comes with a USB interface and an 8 pin circular connector. Standard modules can be analog modulated up to 20 kHz. Special versions are available to cover even higher modulation frequencies, up to 1 MHz for the TTL option – contact us with your requirements. An interlock feature enables the user to shut the unit down and can also be used as a TTL on/off control. In addition a mechanical shutter option is available to provide extra flexibility for controlling laser output power. The unit can be configured with our supplier’s patented inline optical tap for forward power monitor feedback, to further improve short term and long term power stability. Both the pigtail and receptacle style sources offer the choice of polarization maintaining, singlemode, or multimode fiber outputs and a wide range of connector or receptacle types. An output fiber collimator or focuser can be added to the output fiber as an option.

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
