1550nm Suppression Carrier Single Side-band Modulator Module
|
Product description |
ROF-ModBox-CS-SSB-1550 Suppression Carrier Single Sideband Modulation Unit is a highly integrated product of Conquer Photonics with independent intellectual property rights.
The product integrates double-parallel Mach-Zehnder modulator, bias controller, RF driver and other necessary components into a unit, which doesn't only facilitate the user, but also greatly improves the reliability of the MZ intensity modulator. What's more, it can be customized according to user's requirements.
