40G QSFP+ Cisco Module With Breakout 4x10G & OM3/OM4 Support For Data Centers
The Cisco QSFP-40G-CSR4 is a high-performance 40G QSFP+ optical transceiver designed for data center and enterprise networks. It delivers 40Gbps Ethernet connectivity over OM3/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 4x independent 10G channels (10GBASE-SR) for flexible deployment in existing 10G infrastructures.
Key Features & Benefits:
✅ 40Gbps High-Speed Connectivity – Compliant with IEEE 802.3ba 40GBASE-SR4, ideal for spine-leaf architectures, cloud computing, and high-bandwidth applications.
✅ Breakout 4x10G Support – Uses an MPO-12 connector and can be split into 4x 10G LC duplex connections, maximizing compatibility with 10G switches.
✅ Low Latency & Energy Efficient – Optimized for high-density data centers with low power consumption.
✅ Digital Diagnostics Monitoring (DDM/DOM) – Real-time monitoring of temperature, voltage, and optical power for proactive maintenance.
✅ Hot-Swappable & Cisco Certified – Ensures seamless integration with Cisco Nexus, Catalyst, and other 40G switches.
