Keep short-reach 40 GbE links stable with a QSFP module designed for multimode fiber deployments. The ACCORTEC 462-3624 COMP 40GBASE-SR4 TAA X supports 40GBASE-SR4 Ethernet, making it a fit for switch uplinks, leaf-spine fabrics, and aggregation layers where port density matters. This module is built for teams that need consistent optical performance in tightly packed infrastructure. Its QSFP form factor helps preserve valuable rack space while supporting high-throughput connections between compatible network devices. For environments where sourcing requirements matter, the TAA-compliant designation supports procurement in regulated and public-sector workflows. Use it where short-distance, high-bandwidth connectivity is required and where replacing copper or lower-speed links would create bottlenecks. The 40GBASE-SR4 standard is commonly selected for multimode fiber runs inside the data center, helping preserve signal integrity across controlled distances without overcommitting budget to longer-reach optics that are not needed. For architects balancing performance, compliance, and deployment simplicity, this module delivers a focused answer: 40 GbE connectivity in a compact transceiver built for the job it is meant to do.
