Technical characteristics, technical specifications, performance advantages

High sensitivity receiver optimizes receiver design to improve photoelectric conversion efficiency and signal-to-noise ratio, achieving lower bit error rates at the same optical power, or tolerating lower input optical power at the same bit error rate

Low power coherent DSP is a low-power digital signal processor optimized for urban distance, which significantly reduces power consumption while ensuring performance, meeting high-density deployment requirements

The DSP algorithm for urban nonlinear optimization is designed to optimize the nonlinear characteristics of typical distances (<300km) in urban areas, better balance linear and nonlinear compensation, and improve the performance margin of urban area links

The signal locking and equalization algorithm optimized by the fast convergence algorithm shortens the link establishment and recovery time, and enhances the network& # 39;s dynamic response capability

Thermal stability design is aimed at optimizing the temperature adaptability of urban computer room environments, maintaining stable performance over a wide temperature range and reducing the requirements for environmental control

7.Compatibility and configuration requirements

Table 7: System Compatibility and Deployment Requirements

Specific description of the required category

Host board compatibility must be used for 100G line side card supporting QSFP28 interface, and software support for enhanced receiving mode must be confirmed

Before deploying the optical power budget planning, it is necessary to combine its high receiving sensitivity characteristics and re optimize the system's optical power budget, which may reduce the demand for optical amplifiers

The quality of the fiber optic link requires higher cleanliness of the receiving end fiber and connector quality to fully leverage the advantages of high sensitivity

Heat dissipation and density support high-density deployment, but it is necessary to ensure compliance with device heat dissipation standards to avoid local overheating affecting performance

The mode selection strategy selects the working mode based on the actual link loss budget.For links with high losses, it is recommended to use enhanced reception mode

Network management support is required to enhance the status display, configuration, and performance monitoring of the receiving mode

8.Maintenance and ordering information

Table 8: Maintenance and Ordering Points

Project Information

Component code TN11LSQ

The suffix"SQ" for model identification usually represents Sensitivity enhanced (QSFP28) version

On site operation supports hot plugging, and special attention should be paid to cleaning the fiber end face during operation to avoid contamination that may affect high-sensitivity reception

Performance verification focuses on testing the receiving sensitivity and long-term error stability at the lowest received optical power after installation

Spare parts replacement can directly replace the same type of standard 100G QSFP28 module, but it should be noted that the mode configuration may be different

Application guidance is particularly suitable for the construction or renovation of links in urban areas with known low received optical power or uncertain insertion loss

Core Summary:

TN11LSQ is a 100G high-sensitivity coherent optical module optimized for the special challenges of urban wavelength division networks.The core innovation lies in significantly improving the receiving sensitivity under the standard QSFP28 packaging and power constraints, thereby expanding the power budget margin and network coverage of the urban 100G system.

Core Value Proposition:

Extended coverage: Extend the economically efficient transmission distance of 100G wavelength division to a typical large metropolitan area of 200-250km with greater reliability.

Enhance Resilience: Provide additional"security pads" for common fiber aging, unexpected addition of connection points, insertion of optical monitoring devices, and other situations in metropolitan area networks, and improve the network's resilience to changes.

Simplified design: Higher receiver sensitivity can relax the requirements for transmitter power or line optical amplifier configuration, helping to reduce system complexity and cost.

Smooth Upgrade: Provides a better performance and more flexible deployment option for upgrading existing metropolitan area networks from 10G/40G to 100G.

Selection and deployment key:

This module is an ideal choice for solving the problem of insufficient received optical power caused by " last mile " or " multi node insertion loss accumulation " in metropolitan area networks. When deploying, its high sensitivity characteristics should be fully utilized, and the optical power budget of the entire link should be re examined and optimized to avoid excessive design. At the same time, it is necessary to ensure the high quality of the fiber optic link at the receiving end to fully leverage its performance advantages.
