eNet X65401-ENC 40GBASE-CSR4 QSFP+ MPO/MTP

Keep high-density 40 GbE infrastructure moving with a QSFP+ transceiver designed for short-reach multimode deployments. The X65401-ENC supports 40GBASE-CSR4 signaling over MPO/MTP fiber, making it a practical fit for switch interconnects, storage fabrics, and aggregation layers where port density and link stability matter. Built as a compatible replacement for NetApp and Cisco environments, this module helps preserve procurement flexibility without changing the physical layer design. The TAA-compliant profile supports organizations that must meet sourcing requirements for public sector or regulated deployments. For teams standardizing on multimode infrastructure, CSR4 offers a clean path for short-distance 40 GbE links without moving to more complex optics. Choose this module when you need dependable interoperability, consistent 40 GbE performance, and a form factor that fits established QSFP+ infrastructure. It is a straightforward way to extend or replace optics in production networks while keeping the deployment model familiar to your operations team.
