Cisco QDD-4X100G-FR-S Genuine 400G QSFP-DD 2km MPO-12 SMF Optical Transceiver Module 400GBASE-DR4 10-3510-01
The Cisco QDD-4X100G-FR-S (Part No. 10-3510-01) is a high-performance 4x100GBASE-FR QSFP-DD optical transceiver, designed for high-density data center switches and routers. It adopts advanced 4-lane parallel single-mode technology operating at the 1310nm wavelength, supporting four independent 100G channels or aggregated 400Gbps transmission over standard single-mode fiber (SMF) up to 2 km. Equipped with an MPO-12 APC connector, it complies with IEEE 802.3 and 100G Lambda MSA standards, fully supporting high-density breakout applications (4x100G). Factory-calibrated by Cisco, it provides a highly reliable, cost-effective 400G mid-reach connectivity solution for modern data center spine-leaf fabrics and enterprise aggregation networks.

Product Highlights

Versatile 4x100G Breakout Capabilities: Seamlessly splits a single 400G port into four discrete 100G channels via MPO-12 breakout cabling. This allows high-density 400G switches to directly interface with legacy 100G FR/DR single-mode nodes, significantly protecting past infrastructure investments and drastically reducing migration costs.
Optimized 2km Intra-Data Center Reach: Specifically tailored for large-scale enterprise data center networks, hyperscale cloud fabrics, and campus backbone spans. It delivers reliable, error-free throughput up to 2 km over standard parallel single-mode fiber (SMF) without requiring complex optical amplification.
Advanced 1310nm Parallel PAM4 Architecture: Features a 4-lane parallel optical path configuration running at 100Gbps PAM4 per lane on a dedicated 1310nm baseline. By omitting internal wave-division multiplexing components, it ensures lower latency, exceptional optical signal-to-noise ratio (OSNR), and enhanced overall system resiliency.
High-Density QSFP-DD Form Factor: Utilizes the industry-standard Double-Density micro-pluggable package, maximizing faceplate port density on next-generation network hardware. Engineered with a highly efficient thermal casing to prevent localized hotspots under maximum data payloads.
Carrier-Grade Telemetry & Digital Optical Monitoring (DOM): Cisco-certified components with rigorous factory calibration support real-time DOM tracking under Cisco IOS XR and NX-OS. Operators gain full, proactive visibility over laser transmit/receive power, module temperature, and voltage via standard SNMP or streaming telemetry.
Precision MPO-12 APC Optical Interface: Equipped with a standard 12-fiber MPO interface utilizing Angled Physical Contact (APC) polishing. The 8-degree angled end-face limits back-reflection (Return Loss), providing optimal link performance for high-speed parallel optics.
Seamless Multi-Generation Coexistence: Complies strictly with IEEE 802.3bs and 100G Lambda MSA specifications. Guarantees line-side interoperability in mixed multi-vendor environments, allowing effortless integration with third-party 100G-FR or 400G-DR4/FR4 devices.
Eco-Friendly, Low-Power TCO Efficiency: Optimized non-coherent optical engine keeps typical power consumption within a conservative range ($\le 10\text{W}$ to $12\text{W}$). This eco-conscious, low-heat dissipation design minimizes data center cooling costs and lowers the total cost of ownership (TCO).
