3 Ports PMCIR Fiber Optic Circulators

PM and SM Versions; Panda PM or SM Fiber; 780 to 1550 nm; 3 Ports; Insertion Loss ≤0.7 to ≤1.0 dB Fiber optic circulators act as signal routers, transmitting light from an input fiber to an output fiber, but directing light that returns along that output fiber to a third port. They perform a similar function as an isolator, protecting the input fiber from return power, but also allowing the rejected light to be employed. OZ Optics miniature inline circulators are ideal for OEM applications. They are available with either singlemode or polarization maintaining fiber. OZ Optics’ PM fiber optic circulators are manufactured with polarization maintaining fibers, making them ideal for polarization maintaining applications such as 40 Gbit systems or Raman pump applications. They are also used in double pass amplifiers and in chromatic dispersion compensation modules.  The standard PM fiber alignment is for all power to be transmitted along the slow axis of each fiber (Fast axis blocking). With OZ Optics’ modular design and custom manufacturing capabilities, any of the three ports can be aligned for fast axis coupling. High extinction ratio connectors can also be installed. Regardless of the state of polarization of the return beam, the input fiber will still be isolated from reflected light. For non-telecom wavelengths and high power applications, the cube style circulator is offered. This design is well suited for custom applications. Additional connector and cable options and custom designs are also available. Please forward a detailed description of your application to us.

Non-latching; 1x2, 2x2, 1x4, 1x8; Fiber Type SM, MM; 1240 to 1650 nm; Insertion Loss 1.0 to 2.0 dB; Crosstalk 50 dB; Switching Time 1 ms Sercalo Microtechnology’s BS series are all optical switch solutions for demanding applications in fiber optic instrumentation or communication. The benchtop instrument can switch up to two input fibers to any of up to eight output fibers, independently of data format, wavelength or optical power. The BS series optical switches are available either for single mode (SM) or multi mode (MM) fibers. The optical connections are set by a MEMS based switch network, where micromachined silicon mirrors redirect light to the selected ports. The use of MEMS technology offers solid state reliability together with long term stability and robustness for stable operation. The switch is controlled over an USB connection which also acts as power supply. BS series switches are built using Sercalo Microtechnology’s Telcordia-qualified MEMS technology, which achieves superior reliability and repeatability when compared to traditional mechanical solutions. The switches are fully bi-directional and transparent to the full wavelength range of the installed fiber. When several input fibers are required, the switch architecture can be either blocking or non-blocking. In the blocking architecture when one input is set, the other inputs can only be set to a limited number of “free” ports. In the non-blocking architecture there is no such limitation. Any of the input ports can go to any of the free output ports. But the complexity of the non-blocking architecture is much higher.
