Technical characteristics, technical specifications, performance advantages

The ultimate receiver sensitivity optimization adopts ultra-low noise photoelectric conversion front-end and high-precision clock data recovery circuit.The receiver sensitivity is increased by 1.0-1.5dB compared to the standard 400G module, which is the core of extending the distance

The third-generation ultra strong error correction coding uses cascaded soft decision FEC (such as LDP+RS) with gain>12.5dB, which can still reliably decode at extremely low OSNR, breaking the Shannon limit of traditional FEC

The adaptive nonlinear damage engine AI assisted nonlinear digital compensation can learn and pre compensate for the nonlinear characteristics of specific links, significantly improving the transmission performance on deployed, multi span, and nonlinear complex existing fiber optic networks

Function category Function description Operation and maintenance value

After the link feature learning and modeling module is launched, it automatically conducts multiple rounds of testing to learn the loss, nonlinearity, and PMD characteristics of the current fiber optic link and establish a digital model.Implement"one click optimal configuration", automatically recommend the most suitable modulation format, transmission power and other parameters for the link, simplify the start.

Table 6: Typical Application Scenarios

The core problems and advantages solved by the application scenario recommendation mode

The 400G backbone network PS-8QAM/PS-QPSK achieves nationwide 400G trunk coverage of over 1200km, achieving the ultimate balance between single wave capacity and distance, and reducing the number of electric regeneration relay stations.

The extended PS-QPSK of the transoceanic submarine cable meets the requirements of ultra long distance, large capacity, and high reliability connection from the submarine cable landing station to the inland core data center.

The complex network smooth upgrade adaptive mode is successfully inserted and transmitted over a long distance of 400G new wavelength on existing optical fibers with a large number of 100G/200G services without changing the optical amplifier configuration.

The high latitude/desert mainline arbitrary mode, with its excellent wide temperature stability, operates stably in extreme climate regions such as Russia, Canada, and the Middle East.

7.Compatibility and configuration requirements

Table 7: System Compatibility Requirements

Specific description of the required category

The host board and software host board must be high-performance 400G line cards, and the device software and network management must support their intelligent tuning features and enhanced FEC.

The basic requirements for optical links are that although they have strong performance, fiber optic links still need to have a basic OSNR foundation.It is recommended to use G.654.E fiber optic in ultra long distance scenarios.

It is strongly recommended to use its"automatic link learning" function for the opening process, rather than manual configuration, to achieve optimal performance.

It can be mixed with traditional modules and standard 400G modules in the same fiber, but its optimal transmission power may be different and needs to be optimized uniformly at the system level.

Project Information

Component code TN13LSX

The technical positioning is a"flagship" or"special" solution for the most demanding long-distance scenarios at a speed level of 400G.

From the perspective of total cost of ownership, its high unit price may be offset by factors such as reduced number of electrical relay stations, fiber core savings from higher single wave capacity, and lower long-term operation and maintenance costs.

When the transmission distance requirement exceeds 600 kilometers (16QAM) or 1000 kilometers (8QAM) and the standard module cannot meet it, TN13LSX should be considered as the selection decision point.

Core Summary:

TN13LSX is an engineering masterpiece that pushes 400G technology to the"distance limit".It represents the highest balance point that can be achieved between capacity, distance, and adaptability to complex environments in the field of pluggable coherent optical modules.

Core values:

Breaking the distance barrier: enabling reliable transmission of 400G signals over thousands of kilometers, truly expanding its application scenarios from urban/regional backbone to national and even international trunk lines.

Intelligent breakthrough: Through intelligent functions such as"link learning" and"dynamic fine-tuning", the technical threshold and risk of deploying 400G in ultra long distance and complex existing networks have been significantly reduced.

Facing the current network and the future: Its strong environmental adaptability and tolerance for old fiber optic cables protect the existing fiber optic assets of operators, paving the way for the smooth evolution of the network towards 400G and even higher speeds.

The core difference from TN13LQM (standard type):

TN13LQM is a " mainstream balanced " product suitable for most 400G scenarios. TN13LSX is a " breakthrough " product designed for specific challenging scenarios where distance, environment, or current network conditions push ordinary 400G modules to the edge of performance. Choosing TN13LSX means you have chosen a complete high-performance solution that includes cutting-edge hardware, intelligent algorithms, and professional deployment methods.
