Annex
R-ModBox-CS-SSB-1550 Suppression Carrier Single-Sideband Modulation Unit is a highly integrated photoelectric product with independent intellectual property rights.
The product integrates Mach-Zehnder double parallel modulator, bias controller, RF driver, And other necessary components into a unit, which doesn't only facilitate the user, but also dramatically improves the MZ intensity's reliability modulator. What's more, that can customize it according to the user's requirements.
Fatures：
Low insertion loss
High operating bandwidth
AC220V
Applications：
Optical fiber sensing system
Microwave photonics
Teaching and experimental demonstration system
