Swedish Enterprise-Grade Optical Router PAM4

The STC-QSFPDD-FR4-2KM is a 400Gbps optical transceiver designed for short to mid-range data center and metro network applications. It delivers 400G Ethernet traffic across up to 2 kilometers of single-mode fiber (SMF) using four 100G PAM4 optical lanes. In this evolving landscape, QSFP28 PAM4 DWDM (Dense Wavelength Division Multiplexing) emerges as a practical and high-performance solution for extending 100G and 400G signals across metro, campus, and inter-data-center links. What Does. The Marvell® PAM4 optical DSP portfolio, including Spica™ and Nova™ DSPs, addresses the critical the need for high-bandwidth optical interconnects to power AI infrastructure. Marvell leads the pluggable module ecosystem with low-power, high-performance silicon for AI, cloud, enterprise and 5G. Twin-port OSFP single-mode transceivers house two complete multimode or single-mode optical engines inside that exit to two, 4-channel MPO-12/APC optical connectors creating the twin-ports. Twin-port transceivers can be linked to each other forming an 800Gb/s link and can be linked to two or four. In this paper we experimentally evaluate 100 Gbaud 4-level pulse amplitude modulation (PAM4) and 8-level PAM (PAM8) link in C-band for short reach optical interconnects.
