The QSFP-40G-PLR4 is a high-performance 40GbE QSFP+ optical transceiver designed for long-reach data center and enterprise network deployments. Operating over single-mode fiber (SMF) at a 1310nm wavelength, it supports distances up to 10km and enables high-density connectivity. A key feature of this module is its ability to operate in breakout mode, allowing a single 40G port to be split into four independent 10G-LR connections for flexible network scaling.
