Cisco QSFP-40G-LR4-S Module : 40Gbps Long-Range , Low Power , DDM Support
The Cisco QSFP-40G-LR4-S is a high-performance 40Gbps QSFP+ optical transceiver designed for long-distance data transmission over single-mode fiber (SMF). Ideal for data centers, enterprise networks, and telecom deployments, this module combines high speed, low power consumption, and advanced diagnostics for reliable connectivity.
✅ 40Gbps Ethernet Support – Compliant with IEEE 802.3ba, delivers high-bandwidth connectivity for demanding applications.
✅ 10KM Long-Range Transmission – Uses CWDM technology (4×10Gbps lanes) over single-mode fiber (SMF) for extended reach.
✅ Low Power Consumption (<3.5W) – Energy-efficient design reduces operational costs in data centers.
✅ Digital Diagnostic Monitoring (DDM) – Real-time monitoring of temperature, voltage, and optical power for proactive maintenance.
✅ Hot-Swappable & MSA-Compliant – Easy installation without downtime; works with Cisco Nexus, ASR, and third-party MSA-compatible devices.
✅ Dual LC Connector – Standard interface for seamless integration with existing fiber infrastructure.
