ACCELINK 40G QSFP+ SR4 Transceiver Lenovo 4TC7A85336 | QSFP+ Module

Keep short-reach 40 GbE links consistent in dense switching environments with the ACCELINK 40G QSFP+ SR4 transceiver. This QSFP+ optic is designed for multimode fiber deployments where you need dependable throughput, compact port utilization, and straightforward integration into existing 40 Gb infrastructure. SR4 optics are a practical fit for data center racks, aggregation layers, and top-of-rack switching where short optical runs are common and cable management must stay controlled. The QSFP+ form factor preserves switch density while supporting the bandwidth required for server uplinks, storage fabrics, and east-west traffic patterns. For teams standardizing on 40 GbE, this module helps maintain a clean upgrade path without overcommitting to longer-reach optics that add cost and complexity. It is a focused choice for environments that value the right reach, the right speed, and the right footprint for short-distance fiber links.
