Produktbeschreibung

1.Product Overview

TNU4N501T15 is a high-performance tunable 800G coherent wavelength division multiplexing circuit board for ultra wide spectrum and large capacity transmission scenarios on the OSN 9800 series optical transmission platform.The core feature of this board is its support for ultra wide wavelength tuning range of C+L dual bands, which can fully utilize the low loss window of optical fibers, expand the available spectrum resources of a single fiber by nearly twice, and thus achieve a doubling of the total system capacity.It is designed specifically for global backbone networks, ultra large scale data center interconnection clusters, and network core nodes facing the challenge of fiber optic resource depletion.It is a core strategic component for building future oriented and ultimate scalability ultra high speed optical transmission networks.

2.Core features and differentiated positioning

C+L dual band ultra wide spectrum tunable

The laser supports wide range tuning covering the entire C-band (1529-1567 nm) and extended L-band (approximately 1570-1620 nm).

A single board can work flexibly in the C-band or L-band, or serve as a key unit for building a C+L-band hybrid transmission system, providing unparalleled flexibility for network planning and capacity expansion.

Ultimate single fiber capacity doubling capability

In systems that support the C+L band, deploying such boards can increase the number of transmission wavelength channels and total system capacity of a single fiber by nearly 100% without adding new fibers.It is one of the ultimate means to cope with long-term exponential traffic growth and break through fiber capacity bottlenecks.

High performance 800G coherent transmission engine

Within the ultra wide spectral range, it still maintains high-performance 800G coherent transmission capability and supports software defined modulation formats (such as 64QAM/16QAM/QPSK).

Excellent in band performance ensures stable transmission performance for all channels when coexisting with L-band and C-band signals.

Intelligent multi band management

Support automatic wavelength recognition, band switching, and power balance management.

It can collaborate with Huawei iMaster NCE intelligent control system to achieve unified view, automated planning, and intelligent optimization of C+L band spectrum resources.

Board type: C+L band tunable 800G coherent line interface board

Typical power consumption:<220W (depending on the operating band and modulation format)

Working temperature: -5°C to+55°C (ensuring that the system environment meets the requirements of L-band devices)

Optical module type: Supports specially customized wide tuning range CFP2-DCO coherent optical modules.

2.Line side transmission performance

Line speed: 800G (can be software downgraded)

Modulation format: Software configurable, supporting high-order modulation to meet the combination requirements of different bands and distances.

Wavelength tuning range: covering the C-band and L-band (specific range: C: 1529.16-1567.14 nm, L: extended range, subject to official data sheet).

Working band: The software can choose to work in either the C-band or L-band.

Target transmission distance:

When operating independently in the C-band or L-band, the performance indicators are comparable to standard 800G cards, and support distances from the metropolitan area to the backbone (such as using QPSK to support ≥ 1000km).

In a C+L hybrid system, precise calculations need to be made based on the specific power budget and system design within the frequency band.

Customer side connection: Interconnected with the business board through a high-speed backplane.

Support customer side protocols: 800GE, 400GE, FlexE, OTUCn.

System requirements: It must be deployed in a complete system that supports C+L band transmission, including supporting equipment such as C+L splitters and broadband optical amplifiers.

4.Management and Operations

Band and wavelength management: The network management can clearly display and configure the specific band and wavelength values for the operation of the board.

Performance monitoring: Independently monitor key parameters such as OSNR, optical power, and bit error rate within the operating frequency band.

Spectrum planning tool: It is recommended to deploy it in conjunction with Huawei's professional spectrum planning and optimization tools to achieve optimal performance of the C+L band hybrid system.

4.Typical application scenarios

Ultimate expansion of global backbone network: Deploying C+L band systems on core backbone routes with tight fiber resources or extremely high leasing costs, doubling the capacity of single fibers, and delaying or avoiding the huge investment in laying new fibers.

Hyperscale DCI backbone interconnection: connecting multiple large data center campuses to build a high-capacity"data bus" that meets the massive data synchronization needs of the AI era.

Submarine fiber optic cable system upgrade: As a landing station equipment for submarine cables, it is used to upgrade the capacity of existing submarine cable systems and maximize the utilization of valuable submarine fiber optic resources.

Large metropolitan core network: In the core ring of mega cities, it responds to the concentrated traffic pressure brought by 5G, computing power, video and other services.

5.Summary of Core Values

Capacity doubling, breaking through bottlenecks: providing the ultimate solution of nearly doubling the capacity of a single fiber, completely unleashing the potential of fiber optics, and addressing long-term capacity crises.

Investment protection, future oriented: With a single deployment, it has the ability to evolve towards the C+L band, reserving a clear and economical upgrade path for capacity growth in the coming decades.

Resource optimization and value enhancement: Maximizing the value of existing fiber infrastructure, especially suitable for scenarios where fiber resources are scarce or acquisition costs are high.

Leading technology, building advantages: Deploying cutting-edge ultra wide spectrum technology to build a future oriented network intergenerational advantage.

6.Ordering and Deployment Instructions

Basic board model: TNU4N501T15.

It must be ordered and deployed as part of the C+L band system solution, and the corresponding C+L band optical layer subsystem (such as Huawei's C+L solution kit) needs to be configured synchronously.

Strict and professional C+L band hybrid system design and spectrum planning must be carried out before deployment to ensure optimal overall system performance.
