2.Interface and functional modules

Interface/Module Type Quantity Function Description

The LC/UPC 2 optical monitoring channel receives, processes, and sends optical monitoring signals in two directions

ESFP optical module pluggable 2 supports 1511nm and 1491nm wavelength pluggable optical modules

FE electrical interface RJ45 2 supports transparent transmission of two FE electrical signals

System interface backplane connection - communicates with the main control board (SCC) to transmit overhead information

3.Core functional characteristics

Functional Module Technical Description System Value

Bidirectional OSC processing handles optical monitoring signals in two directions, achieving relay and regeneration of ECC (embedded control channel) information between optical amplification stations.Optical amplifier failures do not affect OSC performance, and the distance between monitoring channels is unlimited, ensuring reliable transmission of network management information

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

IEEE 1588v2 supports processing the IEEE 1588v2 protocol to achieve high-precision time synchronization, providing nanosecond level time synchronization accuracy for 5G bearer and other services

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

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

Line fiber quality monitoring, in conjunction with the"Fiber Doctor" software license, enables online and offline monitoring of line fiber quality, real-time monitoring of fiber attenuation, reflection and other parameters, early warning of potential faults, and assistance in network optimization

Optical layer ASON supports automatic switching of optical layers, providing basic support for intelligent optical networks and achieving automated wavelength level business scheduling and protection

Even if the main control board (SCC) is not installed or faulty, the AST2 board can still ensure ECC transparent transmission between network elements through two optical interfaces, which greatly improves the reliability of network management channels and facilitates remote fault diagnosis and recovery

The loopback function supports outbound loopback for fault segmentation diagnosis and business testing

4.Optical and transmission parameters

Parameter specification remarks

The working wavelength is matched with the SFIU board: T11 is 1511nm, TM2 is 1491nm

Cooperate with FIU board: 1511nm recommended configuration to ensure correct multiplexing and demultiplexing of OSC and main optical channel

The maximum transmission distance budget is 37.5 dB, excluding the insertion loss of FIU or SFIU boards

The pluggable optical module eSFP supports wavelengths of 1511nm and 1491nm, making it easy to maintain and replace

G. 8273.2 supports compliance with ITU-T clock standards

5.Application scenarios

Core Value of Application Scenario Deployment Method

Optical Amplification Station (OLA) monitors the deployment of AST2 boards at each optical amplification station, connected to the optical monitoring channel interface of the FIU board to achieve 3R regeneration of monitoring signals, ensuring reliable relay of network management information during ultra long distance transmission

Time synchronization network nodes are deployed at sites that require high-precision time synchronization, connecting to a BIT or 1588v2 clock source to provide high-precision time and frequency synchronization for 5G base stations, financial dedicated lines, etc

High reliability optical networks utilize their ECC transparent transmission characteristics unrelated to SCC to construct a highly reliable out of band monitoring network.Even if the main control board fails, the network management channel remains unobstructed, making remote recovery easier

Fiber quality monitoring points are used in conjunction with the"Fiber Doctor" software to actively detect fiber degradation at critical nodes, transforming passive fault handling into proactive preventive maintenance

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

6.Maintenance and ordering information

Project Information

Component code TN11AST2 (PN: AAA42599)

Ordering instructions: Please confirm the type of FIU board (SFIU/FIU) and corresponding OSC wavelength (1511nm/1491nm) to be used when ordering

The fiber quality monitoring function of the software license line requires an additional purchase of the"Fiber Doctor Management System Software Fee License"

Compatible with OSN 8800/6800/3800 series subracks, suitable for OSN 9800 platform

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 testing and verifying installation, OSC channel connectivity testing, 1588v2 function verification (if used), and FE transparent transmission function testing are required

Core Summary:

TN11AST2 is a bidirectional optical monitoring channel and timing transmission unit in the OSN 9800/8800/6800 platform.As an OSC processing board, it not only undertakes the reception, processing, and 3R regeneration functions of two directional monitoring signals, but also integrates multiple enhanced features such as IEEE 1588v2 high-precision time synchronization, FE signal transparent transmission, and line fiber quality monitoring.

Core values and positioning:

The cornerstone of reliable network management: regenerating monitoring signals at each optical amplification station and ensuring ECC transparency independent of SCC status, ensuring absolute reliability of network management information during ultra long distance transmission.

Time synchronization enabler: Built in IEEE 1588v2 processing capability, making it a critical node for providing nanosecond level time synchronization in 5G bearer networks.

Intelligent operation and maintenance support: With the help of the"Fiber Doctor" software, active monitoring of the quality of line optical fibers can be achieved, providing a data foundation for preventive maintenance.

Multi service bearer: FE transparent transmission function can provide additional out of band data channels at low cost, improving fiber utilization.

Version uniqueness: TN11 is the only functional version of AST2, widely compatible with mainstream subracks, simplifying network planning and spare parts management.

Application suggestion:

This board is an essential standard configuration component in the OSN 9800/8800/6800 wavelength division system. In links that require the deployment of optical amplification stations (OLA), AST2 board (or OSC board of the same series) must be configured to achieve network management communication. For 5G bearer networks, support for 1588v2 is mandatory. During deployment, it is necessary to correctly configure the 1511nm/1491nm eSFP optical module based on its compatibility with the SFIU or FIU board.
