Keep high-speed aggregation links stable with a 40GBASE SR4 QSFP+ transceiver designed for multimode fiber environments. This module delivers 40 Gbps over 850 nm optics and supports reach up to 400 m on OM4-class MMF, making it a strong fit for short-reach backbone connections where predictable performance matters. The MPO connector and SR4 parallel optics architecture are built for dense switch-to-switch and switch-to-server uplinks, where cable management and port efficiency directly affect operational clarity. For teams standardizing on 40 GbE, this transceiver provides a clean path to higher bandwidth without moving to longer-reach optics that add cost and complexity. Use it where short-distance throughput, fiber density, and compatibility with established 40G infrastructure are the priority. It is a straightforward choice for enterprise networks that need dependable optical transport in the rack, row, or adjacent room.
