Description

The MZM-P70 Packaged Mach-Zehnder Modulator is a high-performance electro-optic modulation solution optimized for C band operation. Designed specifically for fast prototyping, benchtop testing, and proof-of-concept development, this modulator brings the power of plasmonic technology into a user-friendly form factor. 

Unlike chip-level solutions, the MZM-P70 comes as a fully packaged module with reinforced fiber interfaces and a standard 1 mm female RF connector. This design ensures simple handling, reliable connectivity, and integration into existing test equipment without the need for custom fixtures.

Its lumped, low-capacitance RF design and high-speed connectors support signal integrity across wide bandwidths while minimizing insertion losses.

Therefore, if you’re developing analog links, working on digital transmission formats like PAM-4 or PAM-8, or exploring quantum photonics, the MZM-P70 Packaged Mach-Zehnder Modulator provides the performance and flexibility needed to push your project forward.

Thanks to its high extinction ratio (>25 dB) and compact size, it delivers clean modulation and stable operation, even under demanding conditions.

Engineers and researchers working with short-reach links, lab test setups, or optical signal processing systems will benefit from the plug-and-play usability of this device.

* Plasmonic modulators are high-impedance devices. Twice the voltage provided by a 50-Ohm signal source will drop across the plasmonic modulator. Using a DC source or a high-impedance-matched driver, double the voltage is required to switch the modulator from the on to the off state.

** Operation time of 8000 h at 85°C with a Vπ degradation <10%.
