Modulator Driver Modules
Optical Modulator Driver Modules
Centellax is pleased to present the following ultra-broadband optical modulator driver modules. These parts are designed specifically for 43Gbps (40Gbps plus FEC) SONET OC768 / SDH STM256 driver applications, including polymer electroabsorption drivers, and lithium-niobate mach-zehnder drivers. The connectorized modules contain DC blocks and bias adjustment circuitry.
