Non-inverting Optical Modulator Driver

I have a JDSU H301 modulator driver for driving a LiNb Mach-Zehnder at

10 Gb/s. However, it is an inverting driver, which means it expects negative input to produce positive output. Is there any way to externally switch the module so it is non-inverting? Does anyone make non-inverting modules, or are all telecom driver amps supposed to be inverting? I find it frustrating that JDSU doesn't mention that the amp is inverting on their data sheet or app note for the H301.

Thanks

One possibility is to change the DC bias on the M-Z. You ought to be able to move the operating point to the other slope of the sine curve.

Cheers,
