OIF’s High Bandwidth Coherent Driver Modulator 2.0 Implementation Agreement addresses 800G
OIF has released “Implementation Agreement (IA) for High Bandwidth Coherent Driver Modulator (HB-CDM) 2.0.” As the name implies, the new set of specifications builds on the original HB-CDM 1.0 IA released in November 2018 to address 128-GBaud 800-Gbps requirements via the same form factor.
The HB-CDM 2.0 leverages OIF’s standards work in integrated lasers and coherent receivers to double the original IA’s 64-GBaud/400G performance in the original Type 1 form factor. The specifications also cover a flexible printed circuit (FPC) as an alternate interface and higher performance RF pitch options for extended rates to meet future requirements.
“OIF’s HB-CDM 1.0 standard was a critical new component enabling optimized 400G+ metro and long-haul coherent networks, supporting the industry need for more capacity with a standardized footprint, interface and performance,” explained technical editor of the OIF HB-CDM 2.0 IA, Richard Ward, Intel. “The HB-CDM 2.0 is a natural extension covering 128-GBaud in coherent technology for 800G per wavelength and beyond coherent systems. The market demand reinforces OIF’s critical role in creating solutions to fulfill industry requirements and accelerating market adoption of optical networking technologies.”
