OIF’s HB-CDM 1.0 standard was a critical new component enabling optimized 400G+ metro and long-haul coherent networks, supporting the industry’s need for more capacity with a standardized footprint, interface and performance. The HB-CDM 2.0 is a natural extension covering 128GBd in coherent technology for 800G per wavelength and beyond coherent systems.
The HB-CDM 2.0 follows the integrated laser and coherent receiver standards from OIF in enabling next-generation compact, high-performance coherent networking solutions. Since OIF’s HB-CDM 1.0 was released for 64 Gigabaud (GBd), enabling 400Gbps coherent systems, the market has seen a need for increased network capacity and higher performance. The HB-CDM 2.0 leverages the original Type 1 form factor for compatibility with existing systems and also includes a Flexible Printed Circuit (FPC) as an alternate interface and higher performance RF pitch options for extended rates for future systems.
