For Pigtail-style or Receptacle-Style Couplers (FC, FC/APC, FC/AFC, ST, SC, or Angled SC); Wavelength Ranges 180-700, 400-1600 nm; Includes MM Patchcord or Fiber Assembly, Collimating Wrench (ALIGN), Polarization Alignment Jig (POL-ALIGN) and Video/DVD Key to successful alignment of any laser to fiber coupler is the initial task of getting the focused light to strike the core of the single mode (SM) or polarization maintaining (PM) fiber. OZ Optics' START alignment kits for laser to fiber couplers and ALIGN alignment kits for laser diode to fiber couplers simplify this task significantly by first using a multi mode (MM) fiber with a larger, relatively easy to target 50 µm core as the output fiber. Then by observing the output pattern from the MM fiber, one can improve the alignment, so the light is striking very close to the center of the fiber. Once this alignment is optimized, the MM fiber is removed and replaced with the SM or PM fiber. If done correctly, it should only take minor adjustments to successfully couple light into the SM or PM fiber. A video or DVD clearly shows how to align laser and laser diode to fiber couplers using these kits in a clear, step-by-step fashion. START and ALIGN alignment kits are available for both receptacle- and pigtail-style laser to fiber couplers. Perhaps the most difficult task is to align the polarization axis of lasers to the polarization axis of PM fibers. The POL-ALIGN polarization alignment tool makes this adjustment in seconds. The tool consists of a connector that fits the receptacle on the laser to fiber coupler. Inside the connector is a polarizer, aligned 90 degrees to the key on the connector. A laser to fiber coupler’s tilt screws and locking screws must be tightened with just the correct torque. To address this concern, a dedicated torque screwdriver is available.

Tilt Adjustment Technique; Pigtail or Receptacle Style; Fiber Type SM, MM, PM; Typ. Insertion Loss 1 dB; Size 29 x 25 x 43 to 77 x 64 x 72 mm OZ Optics’ UB series of fiber optic U-bracket assemblies are designed to transmit light from an optical fiber, across an air gap, and back into a second fiber with low losses. The U-bracket is pre-aligned at the factory for minimum insertion losses, making it very easy to use. A variety of bulk optical devices, including polarizers, isolators, filters, and waveplates, can be simply inserted into the U-bracket, allowing the user to quickly and easily test or prototype systems incorporating fiber and bulk optics. The U-bracket assembly consists of three parts: an input fiber collimator, the U-bracket itself and an output fiber focuser. Utilizing OZ Optics' patented tilt adjustment technique, losses of only 0.6 dB are achieved across a 60 mm gap for pigtailed single mode fibers, with back reflection levels of -25, -40 or -60 dB available. Connector style assemblies are also available for a variety of connectors, including NTT-FC, AT&T-ST, bare fiber adapters, etc. Typical insertion losses are 1.0 dB across a 60 mm gap for connectorized versions, with back reflection levels of typically -20 dB. U-Brackets are available in different sizes, with different gap spacings according to the customer's needs. Many different custom designs can be made for your application. For instance, source to fiber versions are available, where light from either a laser, a laser diode or a LED is transmitted across the air gap and into the output fiber. Another option is to have a photo detector attached to the output end of the U-bracket to measure the transmitted light. Another device available is a black box with a removable filter holder, to quickly insert and remove a filter from the optical path.
