1550 nm band 10-12.5 Gb/s Intensity Modulator The MX-LN-10 is a lithium niobate (LiNb03) intensity modulator designed for optical communications at data rates up to 12.5 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. Thanks to its low Vπ, the MX-LN-10 is ideally suited for 10-12.5 Gb/s optical transmission with NRZ, RZ, DPSK, Duo Binary modulation formats and is also a key device for a large variety of applications.
