Product Description

1.Product Overview

The SXCL series is a C+L band ultra wideband wavelength division multiplexing system solution designed for the ultimate capacity requirements of the OSN 9800 optical transmission platform in the future.This series is not a single board card, but a system level product combination that integrates dedicated line boards, optical amplifiers, switching and management units.Its core mission is to break through the capacity limitations of the traditional C-band (about 4THz spectrum), and by expanding the utilization of the L-band (about 4.8THz spectrum), nearly double the available transmission spectrum resources of a single fiber, thereby achieving a revolutionary increase in the total capacity of the transmission system without laying new fibers.The SXCL series is a strategic infrastructure solution to cope with the global data flood and solve the"spectrum crisis" of backbone networks.

2.Core values and system characteristics

Doubling spectrum resources, unleashing the ultimate potential of fiber optics

Expanding the working wavelength range from the traditional C-band (1529-1567 nm) to the complete C+L band (approximately 1529-1625 nm) significantly increases the number of available wavelength channels (typically supporting up to 192 waves or more).

On the same fiber optic infrastructure, it can provide a total system capacity that is 80% to nearly 100% higher than pure C-band systems, making it the most efficient and economical way to address the challenges of bandwidth growth in the next decade.

Large capacity transmission capability for all scenarios

Supports mixed transmission of multiple line rates from single wave 100G, 200G, 400G to 800G and even 1.2T, allowing for flexible construction of single fiber transmission systems ranging from tens of Tbps to nearly a hundred Tbps.

With excellent transmission performance, advanced optical amplification and dispersion management technology ensure the stability and long-distance transmission capability of C-band and L-band signals working together in an ultra wide spectral range (supporting over 1000km of wireless relay transmission).

Intelligent full band unified control

By adopting intelligent gain balancing and power management technology, the power imbalance caused by the difference in fiber loss characteristics between the C-band and L-band is automatically compensated, ensuring the optimal overall performance of the system.

Through the iMaster NCE intelligent control system, a unified view of C+L full band spectrum resources, automated wavelength scheduling, and intelligent operation and maintenance can be achieved, greatly simplifying the management complexity of ultra wideband systems.

High integration and green energy-saving design

By adopting highly integrated optical layer devices and optimized system design, we strive to control the growth of device volume and power consumption while providing doubled capacity, pursuing higher"bit/watt" energy efficiency ratios.

3.System composition and key technologies

1.Core components

C+L band tunable circuit board: such as TNV3N401, TNU5N401 and other enhanced models that support C+L operation, both the transmitting and receiving units can be tuned throughout the entire C+L band.

C+L-band optical amplifier: a specially designed broadband erbium-doped fiber amplifier (EDFA) or Raman amplifier that can provide flat and high gain amplification for both C-band and L-band signals simultaneously.

C+L-band multiplexer: A high-performance wavelength division multiplexing/demultiplexing device that enables the synthesis and separation of C-band and L-band optical signals.

Intelligent optical layer management unit: responsible for real-time monitoring and automatic adjustment of power, gain, and noise across the entire frequency band.

2.Key technological breakthroughs

Wide spectrum gain equalization technology: solves the challenge of uneven gain in the ultra wide spectrum range, ensuring consistent performance across all wavelengths.

C/L band collaborative optimization technology: Optimize the power ratio and noise impact between two bands to achieve a system performance of 1+1>2.

Intelligent spectral analysis and management: Real time monitoring of the shape and health status of the full band spectrum, supporting predictive maintenance.

4.Typical application scenarios

Ultimate expansion of global core backbone network: Deploying SXCL system on core backbone routes with rapid traffic growth, tight fiber resources, or extremely high leasing costs, achieving intergenerational capacity leap through a single upgrade, and alleviating bandwidth pressure in the long run.

Ultra large scale data center interconnection backbone: a super data center cluster that connects computing power hubs or top cloud service providers, building a"data super highway" that meets the demand for EB level data exchange in the AI era.

Submarine Cable System Capacity Upgrade: Used to upgrade existing transoceanic submarine cable systems, maximize the utilization of extremely valuable and expensive submarine fiber optic resources, and enhance international communication capacity.

Cracking the bottleneck of capacity in the core network of large metropolitan areas: In the core environment facing pipeline resource depletion in mega cities, SXCL system is deployed to provide sufficient underlying bandwidth guarantee for 5G, computing power, 8K video and other businesses.

5.Summary of Core Values

Economically efficient and future oriented: Obtaining nearly doubled network capacity at a much lower cost than laying new fiber optic cables is the optimal technological path to protect existing investments and face future growth.

Cracking the resource bottleneck: fundamentally solving the long-term bottleneck of limited fiber spectrum resources, clearing the basic network obstacles for the sustainable development of the digital economy.

Technological leadership advantage: represents the highest level of optical transmission system design, and deploying this solution will enable network infrastructure to have long-term technological leadership and competitiveness.

Green and sustainable development: By increasing the capacity density of single fibers, the energy consumption and space occupation per unit bit transmission have been significantly reduced, which is in line with the development trend of green ICT.
