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. Insatiable – that's a word that so aptly describes the ever-growing bandwidth. PAM4 is a branch of the pulse amplitude modulation (PAM) technology, which is a mainstream signal transmission technology following non-return-to-zero (NRZ). So what is PAM4 modulation and how is it transforming optical networking?To enable Ethernet speeds of 400G and beyond, PAM4 multilevel signaling is required, rather than NRZ modulation preferred for 100G applications. 26 Billion in 2026 and is projected to reach USD 30.

How to determine if a device is a GPON or EPON
Check the technical specifications: a GPON device must be marked ITU-T G. Some devices are XPON (GPON + EPON) and automatically adapt to the detected OLT — this is the case for V-SOL ONUs such as the Ref 7025. PON (Passive Optical Network): Uses passive splitters to deliver fiber connectivity to multiple end-users without requiring active electronics in the distribution network, reducing maintenance complexity and power consumption. It uses a point-to-multipoint architecture that allows one optical fiber to serve multiple homes or businesses, with downstream speeds up to 2. The core advantage of PON lies in its capability to furnish high-bandwidth, low-latency. The answer isn't a simple one, as it depends on your specific requirements for bandwidth, compatibility, and cost. At their heart, the primary difference lies in the protocols they use. EPON (Ethernet PON). EPON stands for Ethernet passive optical network. This is what distinguishes EPON from GPON.
