With the OPM series, OZ Optics offers inline optical power monitors and tap couplers based on a revolutionary, patented technology. These taps and monitors provide a way to easily measure the signal intensity through an optical fiber in a simple, miniature package and are ideal for real time monitoring and feedback for optical amplifiers or WDM systems as well as for fiber optic sensors.

Traditional monitoring systems typically use fused couplers to tap a fixed amount of light into another fiber that guides the optical power to a photodiode. This method is bulky and must be done using discrete components.

In contrast, OZ Optics' OPM series of optical taps direct a controlled amount of light from the fiber core to the cladding surface where it can be directly monitored with high efficiency and very low loss. This inline tapping is accomplished without bending, shaping, or otherwise distorting the fiber. As a result, the tap can be directly incorporated into optical assemblies, without affecting the original functionality.

While taps are directional in nature (ideal for monitoring traffic independently of signals travelling back through a network link), bi-directional versions are also available and can be provided on request.

OPM taps can be fabricated into standard single mode (SM), polarization maintaining (PM), multi mode (MM), photonic crystal (PC) and other specialty fibers, for any design wavelength and with different tap ratios available upon request.

OPM optical power monitors combine the optical tap design with a photodiode in an integrated package and are available in different configurations with Si and InGaAs detectors for different wavelength ranges. The devices produce a current proportional to the optical power within the fiber, and the small size and simple interface makes it very easy to design into optical hardware. Multiple channel power monitors for WDM applications are available upon request.

PZ1 Fiber Stretchers
High Speed; Fiber Type SM, PM, RC; 780-1625 nm; Fiber Length 5-17 m; Fiber Stretch 0.035-0.21 µm/V; Fiber Leads 1 m, 0.9 mm OD Jacket; Connector Type Bare Fiber, FC/PC, FC/APC The PZ1 series are the high-speed members of Optiphase’s family of fiber stretchers. 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.
