A system comprising: a first system (102, 302) with at least one optical port (106, 306), each optical port comprising a downstream optical transmitter (108, 308) configured to generate an inverse-return-to-zero line coded downstream data signal, and an upstream optical receiver (110, 310) configured to receive a return-to-zero line coded upstream data signal; a Laser-on-CMOS, complementary metal-oxide-semiconductor, chip (126a, 126b, 304) with at least one integrated optical port (132, 322), each integrated optical port comprising a downstream optical receiver (136, 326) configured to receive a first portion of the inverse-return-to-zero line coded downstream data signal, and an upstream reflective light generating device (134, 324) configured to receive a second portion of the inverse-return-to-zero line coded downstream data signal and use pulses in the inverse-return-to-zero line coded downstream data signal and a return-to-zero encoded electronic data signal to modulate and transmit the return-to-zero line coded upstream data signal such that the inverse-return-to-zero line coded downstream data signal optically seeds the return-to-zero line coded upstream data signal resulting in both the inverse-return-to-zero line coded downstream data signal and the return-to-zero line coded upstream data signal each having the same wavelength; and an optical fiber (146, 338) coupled between the first system and the Laser-on-CMOS chip and configured to transmit the inverse-return-to-zero line coded downstream data signal and the return-to-zero line coded upstream data signal therebetween; wherein the Laser-on-CMOS chip comprises a signal synchronizer that interleaves the return-to-zero line coded upstream data signal by one-half bit with respect to the incoming inverse-return-to-zero line coded downstream data signal. a first system (102, 302) with at least one optical port (106, 306), each optical port comprising a downstream optical transmitter (108, 308) configured to generate an inverse-return-to-zero line coded downstream data signal, and an upstream optical receiver (110, 310) configured to receive a return-to-zero line coded upstream data signal; a Laser-on-CMOS, complementary metal-oxide-semiconductor, chip (126a, 126b, 304) with at least one integrated optical port (132, 322), each integrated optical port comprising a downstream optical receiver (136, 326) configured to receive a first portion of the inverse-return-to-zero line coded downstream data signal, and an upstream reflective light generating device (134, 324) configured to receive a second portion of the inverse-return-to-zero line coded downstream data signal and use pulses in the inverse-return-to-zero line coded downstream data signal and a return-to-zero encoded electronic data signal to modulate and transmit the return-to-zero line coded upstream data signal such that the inverse-return-to-zero line coded downstream data signal optically seeds the return-to-zero line coded upstream data signal resulting in both the inverse-return-to-zero line coded downstream data signal and the return-to-zero line coded upstream data signal each having the same wavelength; and an optical fiber (146, 338) coupled between the first system and the Laser-on-CMOS chip and configured to transmit the inverse-return-to-zero line coded downstream data signal and the return-to-zero line coded upstream data signal therebetween; wherein the Laser-on-CMOS chip comprises a signal synchronizer that interleaves the return-to-zero line coded upstream data signal by one-half bit with respect to the incoming inverse-return-to-zero line coded downstream data signal.
