Description

High-density 400G OSFP transceiver for short-reach parallel single-mode deployments. 400GBASE-DR4 optics operate over 4x100G lanes at 1310nm to 500m on OS2 SMF via MPO-12. Ideal for spine–leaf links and 4x100G breakout topologies where low latency and high throughput are required. Optical interop with standards-compliant DR4 optics in other form factors is supported when link budgets match.

Features

- Standards-based 400GBASE-DR4 for reliable 500m links
- High-density parallel SMF over MPO-12 for simplified leaf–spine cabling
- 4x100G PAM4 lanes enable flexible 400G or 4x100G breakout deployments
- Interoperable with compliant DR4 optics across form factors
- Digital diagnostics (DOM) for real-time link monitoring
