3.Core functional characteristics

Functional Module Technical Description System Value

Bidirectional OSC processes monitoring signals from both the receiving, processing, and reproducing directions, and performs 3R regeneration of signals at each station to ensure reliable relay of network management information during ultra long distance transmission.OLA failures do not affect OSC performance

TN12ST2 has added a new function for monitoring the quality parameters of fiber optic cables in real-time, which can assist in determining the health status of fiber optic links, warning potential faults in advance, and achieving preventive maintenance

IEEE 1588v2 supports high-precision time synchronization protocols, which can extract clock signals to provide synchronization for network elements and also transmit clock signals to downstream network elements to provide critical support for time sensitive services such as 5G mobile backhaul

FE transparent transmission supports transparent transmission of two FE electrical signals without occupying the main channel resources, providing an additional out of band data channel that can be used for video surveillance or other management data

The physical clock function supports physical layer clock synchronization, providing high-precision frequency synchronization to meet the requirements of traditional TDM services

The 3R regeneration function re amplifies, reshapes, and timing the monitoring signal at each optical amplification station to correctly receive monitoring information segment by segment and add new monitoring signals, ensuring ultra long distance monitoring

4.Optical and transmission parameters

Parameter specification remarks

The working wavelength should be matched with the SFIU board: RM1 is 1511nm, RM2 is 1491nm, and it needs to be correctly matched with the FIU/SFIU board

The maximum transmission distance budget is 40.5 dB, excluding the insertion loss of the FIU board

The plug-in optical module eSFP supports different wavelengths, making it easy to maintain and replace

OSC interconnection rule 12ST2 can only match the requirements with 12ST2 interconnection version

6.Application scenarios

Core Value of Application Scenario Deployment Method

The Optical Amplification Station (OLA) monitors the deployment of ST2 boards at each station, which are connected to the optical monitoring channel interface of the FIU/SFIU board to achieve 3R regeneration of monitoring signals, ensuring reliable relay of network management information during ultra long distance transmission

The nodes that require fiber quality monitoring deploy TN12ST2 at critical line nodes, utilizing its unique fiber quality monitoring function to actively detect fiber degradation and transform passive fault handling into proactive preventive maintenance

Time synchronization network nodes are deployed at sites that require high-precision time synchronization, supporting IEEE 1588v2 protocol to provide nanosecond level time synchronization for 5G base stations, etc

The FE out of band data channel utilizes the FE transparent transmission function to transmit additional data for auxiliary systems such as video surveillance and environmental monitoring without occupying the main business wavelength

Remote network element management is achieved through OSC channel.Users can log in to manage NE2 and NE3 through NE1, achieving unified management of the entire network

7.Requirements for compatible board cards

Explanation of requirements for board version coordination

FIU board 13FIU03 or 16FIU01 ensures correct multiplexing and demultiplexing of OSC and main optical channel

SFIU board 11SFIU01 ensures correct multiplexing and demultiplexing of OSC and main optical channel

8.Maintenance and ordering information

Project Information

Component code TN12ST2

Ordering instructions: When placing an order, it is necessary to confirm the type of FIU/SFIU board used in conjunction with it and the corresponding OSC wavelength (1511nm/1491nm)

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 installation, OSC channel connectivity testing, 1588v2 function verification (if used), FE transparent transmission function testing, and line fiber quality monitoring function verification are required for testing and verification

Spare parts management, as the core board for OSC processing, is recommended to configure spare parts at OLA sites and critical nodes

Software dependency requires support from the host software version (V100R001C20SPC360 and above)

Version precautions: TN12ST2 is not supported in version V100R001C30

Core Summary:

TN12ST2 is a unidirectional optical monitoring channel and timing transmission unit for enhanced monitoring requirements in the OSN 9800 platform.In addition to the basic OSC processing function, it adds line fiber quality monitoring function, which is its core difference from TN11ST2/TN13ST2.The board performs 3R regeneration on monitoring signals at each optical amplification station to ensure absolute reliability of network management information during ultra long distance transmission.It also supports IEEE 1588v2 high-precision time synchronization and transparent transmission of two FE signals.

Core values and positioning:

Unique Fiber Quality Monitoring: Compared to other ST2 versions, TN12ST2 supports line fiber quality monitoring, providing a data foundation for preventive maintenance

Reliable network management cornerstone: 3R regeneration function ensures unlimited monitoring channel distance, and OLA failure does not affect OSC performance

Time synchronization enabler: Built in IEEE 1588v2 processing capability, providing nanosecond level time synchronization for 5G bearer networks

Strict version matching requirements: When OSC is interconnected, 12ST2 can only be docked with 12ST2 and cannot be mixed with other versions

Application suggestion:

This board is an optional configuration component for OLA stations in the OSN 9800 wavelength division system, especially suitable for scenarios that require line fiber quality monitoring. When deploying, attention should be paid to its version matching requirements (only compatible with TN12ST2), and it should be used in conjunction with 13FIU03/16FIU01 or 11SFIU01. For scenarios that do not require fiber quality monitoring, TN11ST2 or TN13ST2 are more flexible choices (TN13ST2 can be interconnected with TN11ST2).
