1550nm强度调制器
The Photline MX-LN series are lithium niobate (LiNbO3) intensity modulators designed for optical communications at data rates up to 44 Gb/s.
The X-cut design of these Mach-Zehnder modulators confer them an unmatched stability in a wide range of operational conditions, as well as a zero chirp performance. Ixblue proprietary waveguide design offers a low insertion loss combined with a high contrast. The MX-LN series are ideally suited for 10 Gb/s up to 44 Gb/s optical transmission with NRZ, RZ, DPSK, Duo Binary modulation formats and are key device for a large variety of high bandwidth applications.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
