Technical characteristics, technical specifications, performance advantages

Probability shaping technology optimizes the distribution of signal constellation points to make the signal characteristics closer to Gaussian distribution.Compared with standard QPSK, it improves the OSNR margin by about 1-1.5dB and has better error performance at the same distance

Enhanced soft decision FEC uses a higher gain soft decision forward error correction algorithm to provide a net coding gain of approximately 8.5dB, with stronger error correction capability and support for longer distance transmission

Adaptive equalization advanced digital signal processing algorithm, real-time optimization of equalization parameters to better cope with complex link nonlinear effects and polarization state changes

Performance monitoring enhancement integrates more refined performance monitoring units to provide more accurate OSNR estimation and link performance diagnostic information

6.Application scenarios

Table 6: Typical Application Scenarios

Application scenarios, applicability, and technological advantages reflected

Ultra long distance backbone transmission across provinces and national trunk networks, with transmission distances exceeding 1500 kilometers.Enhanced OSNR tolerance and FEC gain ensure reliable transmission over long distances

In complex link environments, fiber aging, high PMD, and links spanning multiple operational boundaries, powerful DSP compensation capabilities and adaptive balancing are used to cope with complex damage

System expansion and upgrade: Adding new wavelength probability shaping technology to existing systems that are approaching the limit of OSNR can achieve better performance and improve the success rate of expansion under the same OSNR

High reliability network finance, government and enterprises require extremely high availability for dedicated line networks.Excellent receiving sensitivity and robustness reduce interruption risks

7.Compatibility and configuration requirements

Table 7: System Compatibility Requirements

Specific description of the required category

The compatibility of the host single board must be used in conjunction with the specified TN series line side board card, and the single board software must support the module characteristics

The system software requires that the device host software version support probability shaping and enhanced FEC functionality (usually requiring newer versions)

Network management supports upper layer network management (such as U2000, iMaster NCE) and needs to support configuration and monitoring of enhanced functions for this module

The optical layer system is compatible with the existing 100G system, but it should be noted that it may have higher requirements for OSNR and requires system level verification

Spare parts compatibility can replace standard 100G CFP2-DCO modules (such as TN11LDCT81), but it is necessary to ensure that the motherboard card and software support are available to fully utilize performance

8.Ordering and maintenance information

Table 8: Maintenance and Ordering Points

Project Information

Component code TN11LDCT15

Module identification can be distinguished by module electronic tags, which contain information such as model, serial number, and supporting features

On site replacement supports hot swappable replacement, and after replacement, the working parameters (such as wavelength) need to be reconfigured in the network management system

After performance verification replacement or new installation, it is recommended to conduct bit error rate testing and key performance parameter checks

Typical fault characteristics include sudden increase in bit error rate, frequent FEC error correction counting, laser related alarms, DSP loss of lock, etc

Upgrade suggestion: Upgrade from standard module to this point.It is recommended to evaluate whether the OSNR margin of the current network optical link meets the requirements

Core Summary:

TN11LDCT15 is a high-performance version of the 100G CFP2-DCO optical module series.Based on the standard DP-QPSK module, it significantly improves the optical signal-to-noise ratio tolerance and transmission distance by introducing probability shaping (PS) technology and enhanced soft decision FEC.It is a solution designed to cope with more demanding, longer distance, or complex fiber optic transmission environments.

The main difference from standard modules such as TN11LDCT81 is its superior receiving sensitivity, stronger non-linear tolerance, and longer theoretical transmission distance. When planning the system and selecting spare parts, it is necessary to choose the most suitable module model based on the actual transmission distance requirements and the current network OSNR margin, and confirm before deployment that the entire link (including the optical amplifier system) can meet its higher performance requirements.
