Inphi is new Canopus coherent digital signal processor (DSP), which it calls the industry’s first merchant 7nm coherent DSP.
Inphi Announces Commercial Availability and Production Ramp of COLORZ® II 400ZR and ZR+ QSFP-DD Transceivers
leader in high-speed data movement interconnects, today announced the commercial availability and production ramp of COLORZ® II 400ZR, the industry’s first QSFP-DD pluggable coherent digital signal processor transceivers for cloud data center interconnects (DCIs). For the first time, cloud operators can connect their data centers within a region with high performance, low power, small form factor 400G coherent optics transceivers without the need for a separate transport box. A longer reach variant, COLORZ II 400G ZR+, which extends the reach of COLORZ II from 120km to about 400km, is in final stages of qualification and expected to be commercially available starting next month.
The DSP(coherent digital signal processor) will provide low-power and high-density QSFP-DD, OSFP and CFP2-DCO coherent pluggable modules. It makes high-density internet protocol (IP) over dense wave division multiplexing (DWDM) on switch and router platforms a reality, and is designed to deliver the performance levels required for metro and long-haul networks. Switches and routers will be able to offer the same port density of coherent interfaces as client ports with capacities of up to 14.4 Tb/s per rack unit, representing a 3x increase over current coherent port densities.
Canopus’ DSP architecture implements probabilistic shaping, a technique that maximises data-rate at longer fibre distances and delivers lower deployment cost per bit. Its low power implementation in 7nm silicon geometry, says Inphi, delivers more than 75 per cent reduction in DSP power dissipation and size compared to the current generation of coherent DSPs. Additionally, Canopus’ design gives operators the flexibility to select either ZR or high-performance modes, for a wide range of network applications.
