Description

High-transmit-power 400G ZR+ coherent QSFP-DD for extended metro/regional spans and ROADM-heavy routes on amplified C-band DWDM systems. DCO architecture with tunable wavelengths enhances OSNR tolerance and simplifies multi-vendor deployment in open line systems. Optimized for challenging paths that need additional launch power and robust performance.

Features

- High-TX-power ZR+ coherent performance for tougher DWDM routes
- C-band tunability for wavelength agility
- DCO for robust signal processing and manageability
- QSFP-DD footprint for dense 400G deployments
- Designed for amplified links and ROADM networks

FAQs

Q: When should I choose a high TX power ZR+ module?
A: Use it for longer spans, higher-loss routes, or multi-ROADM paths where additional launch power helps meet OSNR and link budget requirements.

Q: Is it tunable across the C-band?
A: Yes. It supports C-band DWDM tunability for flexible wavelength assignment.

Q: What equipment compatibility is required?
A: A QSFP-DD port with firmware support for ZR+ coherent DCO optics and an amplified DWDM line system.

Q: What fiber and connector are used?
A: OS2 single-mode fiber with LC duplex connectors.
