产品简介 

The Phoenix Photonics in-fiber LP01-LP11 mode coupler is for use with dual mode optical fiber. The mode coupling is achieved by a Long Period Grating (LPG). The principle of operation is to create a periodic mode coupling in the fiber at the beat length between the two modes. Phoenix creates the coupling using the electric arc technique. The grating created in the fiber will couple power between the LP01 mode and the LP11 mode when the period is matched to the beat length between the modes at the central operational wavelength.

Available at center wavelengths in C&L band, the center wavelength, output mode isolation and bandwidth is defined by the grating period and number of coupling points. The converter can be used to convert LP01 to LP11 or conversely to couple LP11 to LP01 and can be used in both mode multiplexers and demultiplexers. Higher order mode converters for 4-mode fibers are available on request.
