Standard
- CEI-28G-VSR
- QSFP28 MSA
- SFF-8636
Application
- High-speed 100G channels connecting 500 meters between different cabinets within the data center (core application) – Spine-Leaf architecture;
- 100G DR1 is used in combination with 400G DR4 to achieve 1:4 branching and flexible expansion: the data center smoothly evolves to 400G;
- During the upgrade from 100G to 400G, DR1 can be used as a transitional solution, without the need for re-wiring;
- The silicon photonics version of 100G DR1, due to its low power consumption and high density characteristics, is suitable for AI data centers;
- It supports the interconnection of GPU servers in the AI training cluster, and the silicon photonics solution provides cost advantages for large-scale deployment.
