Optech OPNR-SX5-13-CBN: 1.6T OSFP224 DR8 IHS Transceiver for NVIDIA Quantum-X800 AI Fabrics

AI training clusters are pushing network bandwidth and thermal budgets to the limit—especially as 800G transitions to 1.6T at the system edge. Optech’s OPNR-SX5-13-CBN is a 1.6T OSFP224 DR8 IHS optical transceiver engineered for next-generation AI/HPC fabrics, with a strong focus on real-world interoperability, air-cooling readiness, and clean migration paths from 800G to 1.T6.

Designed and manufactured in Taiwan, this module is fully validated for interoperability with NVIDIA Quantum-X800 air-cooled switches, and is compatible with DGX B300 and GB300 server architectures, enabling fast, scalable adoption in modern GPU clusters.

Key Benefits for AI Networking Deployments

1) Validated with NVIDIA Quantum-X800 Air-Cooled Switches

Interoperability is not a checkbox—it’s what keeps large GPU fabrics stable at scale. OPNR-SX5-13-CBN is fully validated for interoperability with NVIDIA Quantum-X800 air-cooled switches, helping reduce bring-up risk and speeding production deployment.

2) Compatible with DGX B300 and GB300 Architectures

As next-generation GPU platforms raise per-node bandwidth, optical links must keep pace without adding operational complexity. This module is compatible with DGX B300 and GB300 server architectures, supporting high-density, high-throughput connectivity requirements common in AI training and inference clusters.

3) Smooth Migration: 1.6T to 2×800G NIC Connectivity

A practical transition strategy matters. OPNR-SX5-13-CBN supports 1.6T to 2×800G NIC connectivity, enabling flexible port planning and breakout-friendly architectures—ideal for phased upgrades where 800G and 1.6T may coexist across racks or pods.

4) Air-Cooling Ready with IHS and ≤25W Power Envelope

Thermals often define what’s deployable in production. The module integrates an IHS (Integrated Heat Spreader) and keeps maximum power consumption at ≤25W, supporting air-cooled system designs where predictable thermal performance and power budgeting are critical.

5) 8×200G PAM4 Electrical Modulation for OSFP224 Platforms

Built for OSFP224 ecosystems, the transceiver uses 8×200G PAM4 electrical modulation, aligning with modern switch/NIC SerDes roadmaps and enabling high aggregate throughput with a lane architecture suited to next-gen platforms.

6) Standards Alignment for Multi-Vendor Integration

To support broad system compatibility and lifecycle planning, OPNR-SX5-13-CBN is compliant with:

OSFP MSA
IEEE 802.3dj_D1.1
CMIS 5.2

This standards alignment simplifies integration into heterogeneous environments and supports consistent monitoring/management via CMIS.

FAQ

What does “OSFP224” mean?
OSFP224 refers to the OSFP form factor designed for 224G-class electrical lanes, commonly used in high-speed platforms moving to 800G/1.6T generations.

What is DR8 in a 1.6T context?
DR8 typically indicates an 8-lane architecture at the optical interface, aligning with the module’s 8×200G PAM4 electrical design to reach 1.6T aggregate throughput.

Why is IHS important for air-cooled deployments?
An Integrated Heat Spreader (IHS) helps distribute heat more effectively to the host cage/heatsink interface—useful in air-cooled systems where thermal headroom is limited.

Does this module support breakout to two 800G links?
Yes. OPNR-SX5-13-CBN supports 1.6T to 2×800G NIC connectivity, enabling flexible deployment and phased upgrades.

Which management standard does it support?
The module is CMIS 5.2 compliant, supporting standardized monitoring and control in OSFP environments.
