Whereas the C-band coherent transceivers are vastly deployed, the O-band coherent transceivers become attractive because the near-zero dispersion window helps to improve energy efficiency by shedding a step of DSP, i.e., chromatic dispersion compensation. In addition, ultra-wideband can be supported in O-band by only a simple single-stage BDFA. Since the ultra-wideband can be achieved without other bands or amplifiers, the BDFA can reduce the total link loss as band multiplexers/demultiplexers are not required. This feature mitigates the higher attenuation in the O-band compared to multiband systems. Furthermore, the ultrawideband can support the higher port counts required in the next generation DCI, where the number of channels is more important than spectral efficiency.
