MXIQER-LN-30

1550 nm band Very High Extinction Ratio IQ Modulator

Modulator
The MXIQER-LN-30 optical IQ modulator is a high bandwidth, low insertion loss,high extinction ratio Dual Parallel Mach-Zehnder Modulator. iXblue proprietary“Magic Junction” (patent n° US2008193077) confers it an unmatched low insertion loss with high optical extinction ratio, and its X-cut design guarantees highstability and zero chirp in a wide range of operational conditions.
The MXIQER modulator is key device in all applications where a combination ofhigh extinction and high bandwidth is required, such as Single Side Band opticalsignal generation with with high suppression ratio of main carrier.
