Marvell also introduced Libra, a 2nm 800G ZR/ZR+ coherent DSP, which enables a lower-power, second-generation COLORZ 800 pluggable.
The products, now with MACsec, expand the company’s coherent DSP and COLORZ pluggable portfolios, delivering optical transmission for hyperscale AI and cloud data center networks.
Marvell COLORZ 1600, with the Electra coherent DSP, connects campus (20km), metro (120km) and regional (1,000km) data centers at 1.6T. It supports in-chip MACsec security, full interoperability across OIF, OpenZR+ and OpenROADM modes, and C and L bands in the OSFP form factor while significantly reducing power per bit compared to existing solutions.
Powered by the Libra coherent DSP, COLORZ 800 now enables cloud operators to secure scale-across interconnects between metro data centers up to 1,000km apart at 800G, and between regional data centers up to 2,000km apart at 600G and up to 3,000km apart at 400G.
Supporting full interoperability across OIF, OpenZR+ and OpenROADM modes, and available for both C and L bands in QSFP-DD or OSFP form factors, COLORZ 800 significantly reduces DCI capital costs compared to traditional systems.
Marvell Electra and Libra coherent DSPs and COLORZ 1600 and the Libra DSP-enabled COLORZ 800 pluggables are expected to begin sampling to customers in the second half of 2026.
