The 400G/800G trunk aggregation node aggregates multi-directional 400G/800G services at the core nodes of the backbone network, with built-in VOA to achieve precise adjustment of on road power, optimize nonlinear effects, and improve system OSNR

Optical layer ASON intelligent network nodes serve as programmable road units in networks that require intelligent features.Optical layer ASON supports automated business scheduling and protection, reducing operation and maintenance costs

The dynamic spectrum leasing network deploys fine grids and power adjustment capabilities in spectrum sharing or leasing scenarios among operators to support spectrum slicing leasing and create new business models

8.Maintenance and ordering information

Project Information

Component code TN15TM20 (specific versions such as TN15TM20-01, etc.)

Ordering instructions: When placing an order, it is necessary to confirm the working band (C-band) and whether attenuation adjustment function is required

On site operation supports hot plugging, and anti-static wrist straps should be worn during operation.Pay attention to cleaning the fiber optic connectors

After the installation of VOA configuration, VOA attenuation calibration needs to be performed through the network management to ensure control accuracy

The MON port can be connected to a spectral analyzer to monitor and output spectra in real-time

After testing and verifying installation, insertion loss testing, channel connectivity testing, wavelength configuration function verification, and VOA function verification are required

Spare parts management, as the core board of ROADM nodes, is recommended to configure spare parts at critical network nodes

Warranty service standard: The warranty period is 1 year, and technical support can be obtained through authorized distributors

Core Summary:

TN15TM20 is a flagship 20 port tunable multiplexer for ultra 100G/400G/800G flexible grid networks in the OSN 9800 platform.Based on TN13TM20, it achieves two core enhancement features: 6.25GHz fine flexible grid and built-in wavelength attenuation adjustment (VOA).

Core values and positioning:

Ultimate Spectrum Efficiency: 6.25GHz minimum slice granularity, supports fine spectrum allocation for any rate business from 100G to 1.6T, and can improve spectrum efficiency by more than 30% compared to 50GHz fixed grid.

Refined power management: Built in 0-15dB adjustable VOA, which can remotely and accurately adjust the transmission power of each uplink channel, optimize nonlinear effects, and provide optimal transmission conditions for high-order modulation signals such as 400G/800G.

Future oriented evolution: Supports channel bandwidth up to 1.6T, fully compatible with the Huawei OSN 9800 platform's evolution towards Tb/s+, protecting network investment.

Green and energy-saving: Adopting a new generation of low-power design, the typical power consumption is only 18W, which is 40% lower than the previous generation products.

Intelligent Optical Layer Core: In conjunction with Optical Layer ASON and online monitoring, it provides the foundation for building an all-optical network for autonomous driving.

The essential difference from TN13TM20:

The 6.25GHz slice granularity of TN15TM20 is a revolutionary improvement, shifting spectrum management accuracy from"extensive" to"refined".At the same time, the built-in VOA realizes the"software definition" of transmission power, providing a key control method for dynamic optical networks.It is the core component for building future highly flexible, intelligent, and efficient optical networks.

Application suggestion:

This board is the core component of the OSN 9800 wavelength division system for over 100G flexible grid networks, especially suitable for scenarios that require fine spectrum management, multi rate hybrid transmission, and large capacity business aggregation, such as backbone network core nodes, large data center interconnection hubs, next-generation ROADM nodes, etc. When deploying, it is necessary to combine the iMaster NCE intelligent control system to achieve automated operation and maintenance of the optical layer and dynamic management of spectrum resources. For scenarios that require the extension of the C-band (supporting 96 waves @ 50GHz), TN97TM20 is a more suitable choice.
