Abstract:
1. A network device, comprising a plurality of driver circuits provided on a first substrate; a plurality of pairs of modulators provided on a second substrate, each of the plurality of pairs of modulators supplying a corresponding one of a plurality of pairs of modulated optical signals; a plurality of resistors provided on the first substrate, each of the plurality of driver circuits supplying a corresponding one of a plurality of driver signals to a corresponding one of the plurality of resistors, each of the plurality of resistors having a corresponding one of a plurality of resistance values, at least one of the plurality of resistance values being different from the remaining ones of the plurality of resistance values, each of the resistors being coupled to a corresponding one of the plurality of pairs of modulators, such that each of the plurality of driver signals is supplied to a respective one of the plurality of pairs of modulators.
