7.Application scenarios

Core Value of Application Scenario Deployment Method

Dual fiber bidirectional DWDM links are deployed in optical line amplification stations (OLAs) for bidirectional transmission, amplifying signals in both directions on a single board to achieve bidirectional amplification, saving 50% of slot space and simplifying system design

The metropolitan core ring network is designed as a dual channel line amplifier or preamplifier/preamplifier in the nodes of the metropolitan core ring to meet the bidirectional business requirements of the ring network.It is equipped with built-in VOA and OPM for remote power balancing and monitoring

Data Center Interconnection (DCI) is located at the intermediate node or terminal station of the DCI link, and simultaneously processes uplink and downlink signals with high integration to reduce equipment costs.Built in monitoring improves operation and maintenance efficiency

Space limited sites are located in sites with tight cabinet space, and the dual channel integration design greatly saves subrack slots when amplifying signals in both directions, making it suitable for expansion and renovation

Optical layer ASON nodes, as manageable and monitored amplification units in networks that require optical layer intelligence, are equipped with OPM and VOA to support automatic performance optimization and fault prediction of the optical layer

8.Maintenance and ordering information

Project Information

Component code TN52DAP

Ordering instructions: When placing an order, it is necessary to confirm the working band (extended C-band), gain range, VOA, and OPM configuration

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

OPM can be used to monitor the real-time performance of each optical channel using the built-in OPM, and monitoring tasks need to be configured through the network management system

After testing and verifying installation, gain calibration, power testing, VOA function verification, and OPM accuracy verification are required

As a highly integrated optical amplifier board, it is recommended to configure spare parts at critical nodes in the network for spare parts management

Core Summary:

TN52DAP is a highly integrated dual channel optical amplification unit board for dual fiber bidirectional links in the OSN 9800 platform.It integrates two independent EDFAs, adjustable optical attenuators (VOA), and optical performance monitoring (OPM) into a standard board, making it an ideal choice for building high-density and intelligent optical layer networks.

Core values and positioning:

The integration advantage of dual channel integration: Single board achieves bidirectional signal amplification, saving 50% of slot space, simplifying fiber optic cable connection and system design, especially suitable for space limited sites or scenarios that require bidirectional amplification.

Intelligent Optical Layer Management: Each channel integrates VOA and OPM, supporting remote power fine adjustment and real-time performance monitoring, providing a data foundation for automatic optimization and fault prediction of the optical layer.

Excellent optical performance: Extended C-band coverage, low noise figure (≤ 5.0dB), high gain flatness (≤ 1.2dB), ensuring long-distance transmission quality of high-speed signals (such as 100G/200G/400G).

Reduce operation and maintenance costs: Built in monitoring reduces the need for external instruments, VOA remote adjustment avoids on-site manual intervention, significantly reducing OPEX.

Application suggestion:

This board is particularly suitable for scenarios that require bidirectional amplification, compact space, and intelligent monitoring, such as bidirectional OLA stations in urban core ring networks, dual fiber amplification of DCI links, and expansion and renovation of old sites. When deploying, it is recommended to combine the iMaster NCE intelligent control system and fully utilize its built-in VOA and OPM functions to achieve dynamic optimization and preventive maintenance of optical layer resources. For unidirectional amplification requirements, TN11DAS1 or TN97OAU2 are more cost-effective choices.
