40Gbps QSFP-40G-SR4 Cisco Module OM3/OM4 Multimode , Breakout To 4x10G
The Cisco QSFP-40G-SR4 is a high-performance 40Gbps optical transceiver designed for data centers, enterprise networks, and high-speed computing environments. This QSFP+ module enables ultra-fast data transmission over OM3 or OM4 multimode fiber (MMF), supporting distances up to 100m (OM3) and 150m (OM4). A key advantage is its breakout capability, allowing it to split into 4x10G SFP+ connections for flexible network scalability.
Key Features & Benefits
✔ 40G Ethernet & High-Speed Data Transfer – Ideal for cloud computing, storage networks, and HPC.
