Ordering instructions: When placing an order, it is necessary to confirm the working band (extended L-band) and flexible grid configuration requirements

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 monitoring port uses two high-precision monitoring ports that can be connected to a spectral analyzer or OPM unit to monitor and output spectra in real-time

After testing and verifying installation, insertion loss testing, directional connectivity testing, wavelength scheduling function verification, VOA function verification, grid configuration verification, and isolation testing are required

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

Core values and positioning:

L-band enabler: As the first model in the WSMD4 series to support L-band, TN13WSMD4 and TN12WSMD4 in the C+band together form a complete C+L-band ROADM solution, achieving single fiber capacity doubling.

Ultimate Spectrum Efficiency: With a minimum slice size of 3.125GHz, it supports fine spectrum allocation for services at any rate from 100G to 3.2T.Compared to 6.25GHz grid, it can further improve spectrum efficiency by more than 20%.

Ultra large capacity support: Extended L-band coverage of 1570.01-1610.19nm, supporting 96 wave @ 50GHz systems, and achieving ultra large capacity of single fiber 192 wave @ 50GHz in conjunction with the C+band.

Industry leading power management: 0-25dB VOA range, 0.05dB step, achieving the most precise routing power control in the industry, significantly improving system performance margin.

Excellent optical performance: 7.0dB ultra-low insertion loss, 30dB adjacent isolation, 45dB directionality, -50dB return loss, providing the best channel quality for high-speed signal transmission.

Collaborative positioning with TN12WSMD4:

TN12WSMD4: Extended C+band (1524.5-1572.06nm), 6.25GHz slice, suitable for C-band ROADM nodes

TN13WSMD4: Extended L-band (1570.01-1610.19nm), 3.125GHz slice, suitable for L-band ROADM nodes

By combining the two, a C+L band ROADM network can be constructed in the same fiber optic cable, achieving ultra large capacity transmission of 192 waves @ 50GHz on a single fiber.

Application suggestion:

This board is the core routing component for L-band ultra 100G flexible grid networks in the OSN 9800 wavelength division system, and is particularly suitable for scenarios that require C+L-band collaborative networking, ultra-fine spectrum management, and 3. 2T ultra high speed support, such as backbone network core nodes, ultra large scale data center interconnection hubs, next-generation submarine cable systems, etc. When deploying, it is necessary to combine TN12WSMD4 (C+band) and iMaster NCE intelligent control system to achieve unified scheduling of the C+L band and automated operation and maintenance of the optical layer. For pure C-band applications, TN11WSMD4 or TN12WSMD4 are more cost-effective choices.
