UAE Telecom-Grade Router QSFP-DD

QSFP-DD modules are essential for high-speed 400G networking in UAE telecom and enterprise environments, supporting AI, cloud, and hyperscale data center applications.Overview of QSFP-DD

QSFP-DD (Quad Small Form-Factor Pluggable Double Density) modules are high-bandwidth optical transceivers designed for speeds from 40G up to 400G. They are widely used in telecom-grade routers, switches, and data center fabrics to enable ultra-low latency, high-density connectivity. QSFP-DD supports backward compatibility with QSFP28 modules, allowing flexible deployment in existing network infrastructures while providing future-proof scalability for AI compute clusters, GPU fabrics, and NVLink/InfiniBand interconnects in the UAE .

Key Features and Benefits
  • High-Speed Connectivity: Supports 400G Ethernet with 8 lanes of 50Gbps signals per fiber, or 4x100G breakout options for flexible network design .
  • Compatibility: Works with Cisco, Arista, Juniper, Dell EMC, HPE, Huawei, Fortinet, and NVIDIA/Mellanox equipment .
  • Optical Interfaces: Available for multimode (OM3/OM4/OM5) and single-mode fibers, with MPO/MTP or LC connectors depending on reach requirements .
  • Applications: Ideal for hyperscale data centers, AI training clusters, cloud workloads, enterprise core networks, and national digital infrastructure projects .
  • Local Availability: UAE suppliers like SFPS.AE and GBICS offer same-day delivery in Dubai, Abu Dhabi, Sharjah, RAK, Fujairah, and Al Ain, often at up to 70% lower cost than OEM modules while maintaining performance .
Cisco QSFP-DD Specifics

Cisco's QSFP-DD portfolio includes 400GBASE-SR4.2, VR4, DR4, and breakout modules. Key specifications include:

  • Bit Rate: 53.125 GBaud PAM-4 per lane (106.25 Gbps/lane)
  • Reach: Up to 100m over OM4 multimode fiber, 30–50m over OM3, and up to 10 km for single-mode LR4 modules
  • Standards Compliance: IEEE 802.3bs, 400GBASE-SR4, 400GAUI-8, 200GAUI-2, and 100GAUI-1
  • Pluggable Open Line System (OLS): Cisco QSFP-DD OLS modules can be directly hosted on routers, enabling coherent DWDM interfaces for distances up to 40 km with Routed Optical Networking (RON) architecture .
Choosing QSFP-DD in the UAE

When selecting QSFP-DD modules for telecom-grade routers in the UAE:

  1. Determine Network Speed Requirements: 100G, 200G, or 400G depending on AI, cloud, or enterprise workloads.
  2. Check Fiber Type and Connector Compatibility: OM3/OM4/OM5 for multimode, single-mode for long-distance links, MPO or LC connectors.
  3. Verify Vendor Interoperability: Ensure modules are compatible with your existing switches and routers.
  4. Consider Local Suppliers: SFPS.AE and GBICS provide tested, certified modules with fast delivery and lifetime warranty, reducing lead times and import costs . QSFP-DD modules are critical for UAE's next-generation digital infrastructure, enabling high-density, low-latency, and scalable networking for AI, cloud, and hyperscale data centers.
