An optoelectronic device can implement an intelligent transmitter module (“ITM”), rather than a conventional TOSA, for the transmission of optical data signals. The ITM can include an optical transmitter, a CDR and driver IC, and a microcontroller and/or linear amplifier. Space available in the optoelectronic device due to using an ITM rather than a TOSA and PCB-bound CDR, driver, microcontroller, and/or linear amplifier can be used for the inclusion of one or more electronic and/or optical components. Electronic components that can be included in a device with an ITM include: an FPGA, a DSP, a memory chip, a digital diagnostic IC, a video IC, a wireless interface, and an RF interface. Optical components that can be included in a device with an ITM include: a VOA, an SOA, a MUX, a DEMUX, a polarization controller, and an optical power monitoring device.
