1550 nm band 40-44 Gb/s Intensity Modulator The MX-LN-40 is a lithium niobate (LiNb03) intensity modulator designed for optical communications at data rates up to 44 Gb/s. The X-cut design of this Mach-Zehnder modulator confers it an unmatched stability in a wide range of operational conditions, as well as a zero chirp performance. Photline Technologies proprietary waveguide design offers a low insertion loss combined with a high contrast. The MX-LN-40 is ideally suited for 40-44 Gb/s optical transmission with NRZ, RZ, DPSK, Duo Binary modulation formats and is also a key device for a large variety of high bandwidth applications.
