Description

High-density 400GbE 1RU fixed system with 32 QSFP-DD ports for scale-out leaf/spine or edge routing use cases. Delivers up to 12.8 Tbps of line-rate forwarding in a compact footprint and operates without high-bandwidth memory (HBM). Ideal for modern DC fabrics and service edge deployments.

Features

- Ultra-dense 32 x 400GbE in a compact 1RU footprint
- Up to 12.8 Tbps of non-blocking throughput
- Flexible 400G to 100G breakout for migration and interoperability
- Carrier-class software stack with model-driven automation
- No-HBM design for low-latency, power-efficient operation

FAQs

Q: What is the difference between models with and without HBM?
A: HBM-equipped systems provide deep buffers for heavy congestion scenarios. This model operates without HBM, favoring reduced latency and power while still delivering high 400GbE density.

Q: Does it support breakout to 100GbE?
A: Yes. QSFP-DD ports can break out to 4x100GbE where supported by platform software and optics.

Q: Can I use QSFP28 or QSFP+ optics in QSFP-DD ports?
A: QSFP-DD ports are typically backward compatible with lower-speed QSFP optics on supported platforms. Check the platform transceiver compatibility list for specific modules.

Q: Which network OS does it run?
A: It is designed for IOS XR, providing carrier-grade routing features and model-driven programmability.

Q: Is this intended for switching or routing roles?
A: It can serve as a routed spine/leaf or edge router in high-density data center and interconnect deployments.
