Description

High-density 400GBASE-FR4 optical module for leaf/spine and aggregation links up to 2 km over single-mode fiber. Uses 4x100G PAM4 wavelengths on the 1310 nm CWDM4 grid with a simple duplex LC interface, easing migration from duplex optics while delivering 400G capacity. CMIS-managed with DOM for real-time diagnostics and designed for standards-based interoperability on 400G QSFP-DD ports that support FR4.

Features

- 400G capacity in compact QSFP-DD footprint
- Duplex LC interface simplifies cabling versus MPO solutions
- Standards-based 400GBASE-FR4 for multi-vendor interoperability
