Industry background

Cloud computing, big data and AI training clusters promote the comprehensive evolution of data center bandwidth from 10G to 25G/100G. Under the Spine-Leaf architecture, optical modules and high-speed cables account for a high proportion of network construction costs, and the mixed use of equipment from multiple brands has become the norm. Improper selection will lead to link jitter, packet loss, and even batch disconnections.

Customer pain points

  • Brands of switches, network cards, and optical modules are mixed and matched, causing frequent compatibility issues;
  • Optical modules for short-distance links in cabinets are costly and consume a lot of power;
  • Medium and long-distance interconnection between buildings lacks reliable backup of 10km/40km single-mode;
  • Link fault location is slow, and spare parts and technical support responses are lacking.

Solution architecture

EB-LINK uses hierarchical networking based on link distance: DAC high-speed cables are used for 1–5m within the cabinet, AOC active optical cables are used for 5–30m across the cabinets, 25G/100G SR4 multi-mode optical modules are used between computer rooms, LR/ER single-mode optical modules are used for disaster recovery between campus buildings and in the same city, and 82599/XL710/E810 series optical fiber network cards are used to reach the server directly.

Recommended product portfolio

  • 100G single-mode/multi-mode optical module (QSFP28, 100G SR4/PSM4/CWDM4/LR4);
  • 25G multi-mode/single-mode optical module (SFP28, adapted for 25G server access);
  • 100G DAC high-speed cable/100G AOC active optical cable (cost reduced to 1/3 of the optical module solution);
  • PCI-EX16 100G dual optical port fiber optic network card (Intel E810), PCI-EX8 10G four optical port network card (Intel XL710);
  • 12-port 24-core LC 10G multi-mode fully equipped ODF patch panel, standard trunk jumpers.

Solution value

  • One-stop supply of full speed, the same brand guarantees end-to-end compatibility;
  • The DAC/AOC short-range solution significantly reduces single-port power consumption and cost;
  • Tested and put on shelves one by one, compatible with mainstream equipment such as Cisco, Huawei, H3C, ZTE, Ruijie, etc., and can be coded;
  • Support branch interconnection from 40G to 10G and 100G to 25G, protecting existing investments.
