Ea modulator driver

Driving Optical Modulator Directly using MPA The MPA Signal Quality Analyzer is an all-in-one solution for these problems, making it easy to increase production yields of . EA/MZ Modulator Driver Gb/s to Gb/s. The PMCC_EAMD12G is designed to directly drive the inputs of EA or MZ Modulators or EML devices at data-rates up-to Gbps. The driver features programmable output voltage swing as well as monitoring, crossing point control, and programmable output DC offset (bias). EA driver is used to drive above EA modulator for E/O conversion, and is required to operate over 40 Gbit/s with an output amplitude of Vpp. This paper reports develop- ment of a 40GbE EA driver IC using high-speed IC process technology based on InP DHBT with high-speed operation and high breakdown voltage characteristics.

Driving Optical Modulator Directly using MPA The MPA Signal Quality Analyzer is an all-in-one solution for these problems, making it easy to increase production yields of optical modulators and transceivers. One type of the external modulator is an EA modulator. Because an EA modulator inherently shows nonlinearity between the modulation signal and the optical output therefrom, a driver to driver the EA modulator usually provides a function to adjust the cross point of the output of the driver, namely, the input of the EA modulator. One of the two modules has an in-house driver IC for Electro-absorption (EA) modulator integrated in a laser chip and the other has no driver IC. These transmitter modules are transmitter optical sub-assembly (TOSA) type devices with flexible printed circuit (FPC) and LC receptacle.
