Scott Wilkinson, Lead Analyst for Optical Components at industry intelligence specialist firm Cignal AI says of the launch: “Marvell’s Orion DSP represents the next step in coherent pluggables after the unprecedented  popularity of 400Gb/s modules. Orion creates the opportunity to eliminate hardware and significantly reduce costs in  regional to long-haul networks, and our conservative forecast calls for nearly 300,000 shipments  of 800Gb/s-capable pluggable modules a year by 2027.”
