7.Compatibility and configuration requirements

Table 7: System Compatibility and Deployment Requirements

Specific description of the required category

The compatibility of the host board must be used for the QSFP-DD interface of the host board, and the power supply and heat dissipation design of the board must meet the strict requirements of 400G high-power modules

The software version requires that the host board software and network management clearly support the management, monitoring, and optimization functions of this specific high-power 400G module

The highest level of safety warning in optical safety regulations requires compliance with high-power laser safety regulations during operation.Only after confirming safety with an optical power meter can operations be carried out

The sub rack of the heat dissipation and airflow design equipment must have strong heat dissipation capabilities.It is recommended to plan a dedicated heat dissipation area to avoid heat accumulation

Fiber optic and link evaluation must use G.652.D or G.654.E ultra-low loss fibers.Strict nonlinear simulation and OSNR budget analysis are required before deployment

Power and nonlinear optimization require optimizing the transmission power and optical amplifier configuration at the system level, achieving the best balance between increasing distance and suppressing nonlinearity

8.Maintenance and ordering information

Project Information

Component code TN14LSC

The model identification module label clearly identifies"400G","High Power", and maximum output power level

Mandatory safety operation process: 1.Network management software shuts down the laser; 2.Physical measurement confirms no light; 3.Wear professional protective goggles; 4.Perform operations

On site deployment and replacement support hot plugging, but it is strongly recommended to perform it in the business maintenance window and conduct heat dissipation checks in advance

Testing and acceptance are required after installation, including emission spectroscopy, output power calibration, EVM testing, 72 hour error stability testing, and system level nonlinear verification

Spare parts and upgrade strategies are key high-performance spare parts for 400G medium to long-distance scenarios.Upgrading from a regular 400G module to this requires a complete network power and nonlinear optimization

Core Summary:

TN14LSC is a high-power QSFP-DD coherent optical module solution designed for the challenge of 400G medium to long distance transmission.It faces the strict requirements of 400G high-order modulation (such as 16QAM) on OSNR and the accompanying power budget pressure.By increasing the output optical power and integrating enhanced digital signal processing, it effectively extends the practical transmission distance of 400G.

Strategic Value:

Pushing 400G from short-term to long-term: Enabling single wave 400G to practically cover regional backbone and even some long-distance trunk scenarios is a key component for 400G technology to enter the mainstream.

The unity of high density and high performance: Within the compact space of QSFP-DD, it achieves transmission performance close to earlier larger packaging (such as CFP2) 400G modules, supporting high port density design for next-generation devices.

Simplify network architecture: A higher power budget helps reduce the number of cascaded optical amplifiers or allows for the use of lower gain/cost amplifiers, thereby simplifying system design and reducing total cost of ownership.

Key considerations:

The application of this module is not just simple " plug and play " , but involves system level optical power and nonlinear re optimization. It is mainly aimed at building new high-performance 400G trunk lines, core DCI links, or serving as a key capacity upgrade anchor for existing networks. Successful deployment relies on precise link simulation in the early stage, strict optical security operations, and the improvement of the operation and maintenance team& # 39;s management capabilities for high-order modulation systems.
