Please log in for more thread options 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 | |||||||||||||

Please log in for more thread options 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, Phil Hobbs | |||||||||||||
