1550 nm band 20 GHz Analog Dual Output Intensity Modulator The MXDO-LN-20 is a lithium niobate (LiNb03) intensity modulator with dual fiber output designed for analog applications at frequencies up to 20 GHz. The MXDO-LN-20 specific design offers an excellent balance of the two complementary fiber outputs. The X-cut of this Mach-Zehnder modulator confers it an unmatched stability in a wide range of operational conditions, as well as a zero chirp performance. The MXAN-LN-20 is ideally suited for 20 GHz analog communications such as RF over fiber and microwave photonics using differential detection.
