Product Description

1.Product Overview

TNU4N404 is a high-density, high-performance dual channel 800G coherent wavelength division multiplexing circuit board on the OSN 9800 series optical transmission platform.This board adopts a breakthrough high-density integration design, integrating two completely independent 800G coherent transmission engines in a single slot, providing a total single slot line capacity of up to 1.6Tbps.It is designed specifically for the interconnection of hyperscale data centers (Hyperscale DCI), core nodes of national computing backbone networks, and future network scenarios facing TB level single slot capacity.It aims to meet the exponential growth of bandwidth demand with ultimate space efficiency and energy efficiency, and is a strategic product for building the next generation of ultra high speed optical transmission infrastructure.

2.Core Features and Breakthrough Design

Industry leading single board 1.6T capacity

The single board integrates dual channel 800G line interfaces, providing a total output capacity of 1.6Tbps and increasing the single slot transmission density to a new height.

This design significantly increases the overall capacity of the equipment, enabling the same total network capacity to be achieved with fewer cabinets in a space limited core data center, significantly reducing space and power consumption costs.

High density integration and advanced heat dissipation

Using innovative photonic integrated circuit (PIC) and electronic integrated circuit designs, two complete sets of high-performance coherent optical engine integrations are achieved within standard board sizes.

Equipped with an intelligent and efficient cooling system to ensure long-term stable operation of dual channels under high loads, meeting the reliability requirements of telecommunications grade.

Independently programmable dual channel architecture

The two 800G channels are completely independent in hardware and management, and can be configured with different line rates (such as 800G/600G/400G), modulation formats, and wavelengths.

Support business isolation between channels, which can be carried to different destinations separately, providing extremely high deployment flexibility and resource utilization.

Ultimate performance for computing power networks

Each channel has the same transmission performance as high-end single channel 800G cards, supporting high-order modulation (such as 64QAM/128QAM) and advanced probability shaping (PCS) technology to optimize the spectral efficiency of medium to short distance transmission.

Fully supports hard slicing technologies such as FlexE and OSUflex, meeting the requirements of deterministic low latency and bandwidth isolation in scenarios such as AI clusters and supercomputing.
