800G QSFP-DD 2xFR4 2km

Overview

The 800G QSFP-DD 2xFR4 transceiver complies with IEEE 802.3cu (2x400GBASE-FR4), using a dual CS interface over single-mode fiber for 2km medium-reach 800G transmission, with an integrated high-performance DSP and digital diagnostic monitoring (DDM) — the next-generation high-speed solution for AI compute clusters and data center backbone interconnect.

Features

Doubled bandwidth: Up to 800Gbps, meeting the massive throughput demands of the AI era.

Medium reach: Single-mode fiber up to 2km, breaking short-reach distance limits.

Flexible breakout: 1-to-2 split turns one 800G port into two 400G links for ultimate networking flexibility.

High density: QSFP-DD packaging, backward compatible with the 400G ecosystem for smooth upgrades without switch replacement.

Low power, high stability: Integrated DSP and DDM ensure low-latency, highly reliable long-reach transmission.

Applications

Distributed AI compute cluster cross-room/cross-building 10k-GPU training interconnect, data center Spine-Leaf core/aggregation high-speed uplink, large campus and carrier edge compute nodes within 2km, HPC cross-building massive data paths.
