1064, 1310, 1550 nm; Modulator Constant 0.8-2.5 rad/V; Maximum Voltage Range ±500 V; Fiber Type HI-1060, SMF28e+; Connector Type FC/APC Optiphase, a leading supplier of ultra-high-performance interferometric systems, offers MFI Michelson and MZI Mach-Zehnder fiber interferometers for use in precision test and measurement instrumentation as well as fiber sensing systems. These interferometers are driven by Optiphase’s own PZ1 low-profile fiber stretcher with enhanced modulation, through a front panel BNC connector. MFI Michelson and MZI Mach-Zehnder interferometers are available in wavelengths from 1064 to 1550 nm. Each interferometer has a “zero meter” path mismatch which provides flexibility to change the delay length to match varying test applications. The standard length shipped is 50 m. Optiphase also builds custom interferometers on request, please contact AMS Technologies and let us know of your specific requirements.

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.
