3.Core functional characteristics

Functional Module Technical Description System Value

The main optical channel multiplexing combines the C-band main optical channel signal with the optical monitoring channel (OSC) signal into one channel for transmission, or separates the OSC signal from the multiplexed signal to achieve efficient coupling of the optical signal between the fiber optic line and the equipment, ensuring independent transmission of the out of band monitoring channel

IEEE 1588v2 clock synchronization support: In systems deploying IEEE 1588v2 clocks, the SFIU board can eliminate the need for 1588v2 clock tuning and delay compensation, significantly simplifying the deployment and maintenance of synchronous clock networks without the need for additional delay compensation tuning, and improving network time synchronization accuracy

The high OSC channel isolation is as high as ≥65dB, far higher than conventional FIU boards, effectively preventing interference from the main optical channel signal to the monitoring channel and ensuring reliable transmission of network management monitoring information in complex optical layer environments

Online optical performance monitoring provides MON monitoring port (if configured), which can be connected to an external spectral analyzer to monitor signal spectra, optical power, OSNR and other parameters in real time without interrupting business for optical layer performance diagnosis and optimization, improving operation and maintenance efficiency

Core Value of Application Scenario Deployment Method

IEEE 1588v2 synchronous network nodes are deployed at OTM/OLA sites that require high-precision time synchronization, eliminating the need for 1588v2 clock tuning and delay compensation, greatly simplifying synchronous network deployment and maintenance

DWDM systems with high isolation requirements use ultra-high OSC isolation of ≥65dB in complex optical layer environments where OSC channels are susceptible to interference to ensure reliable transmission of monitoring channel information, suitable for high-power, long-distance systems

Mobile carrier networks provide high-precision time synchronization transmission channels for wavelength division node deployment in 5G pre/mid transmission networks, meeting the strict requirements of 5G base stations for 1588v2 clock

The financial/government enterprise dedicated line network is deployed on the line side of the DWDM system carrying high-value dedicated lines to ensure business transmission while providing a highly reliable out of band monitoring channel

Core Summary:

TN11SFIU is an enhanced fiber optic interface unit board designed specifically for DWDM systems that require IEEE 1588v2 clock synchronization on the OSN 9800 platform.Based on the standard FIU functionality, it integrates two core features: 1588v2 clock synchronization support and ultra-high OSC channel isolation (≥ 65dB).

Core values and positioning:

1588v2 clock synchronization enabler: In systems deploying IEEE 1588v2 clocks, the SFIU board eliminates the need for clock tuning and delay compensation, greatly simplifying the deployment and maintenance process of synchronization networks.It is a key component in building high-precision time synchronization networks such as 5G bearer networks.

Industry leading OSC isolation: The OSC channel isolation is as high as ≥65dB, far higher than conventional FIU (12dB) and TN16FIU (40dB), which can effectively prevent interference from high-power main optical signals on monitoring channels and ensure reliable transmission of network management information in the most demanding optical layer environment.

Ultra low main optical channel insertion loss: The main optical channel insertion loss is only ≤1.0dB, which is superior to other FIU cards in the same series and minimizes the impact on the system's optical power budget.

Ultra low power consumption and high reliability: With a power consumption of only 0.2W and almost no heat generation, it has extremely high reliability and a long service life.

Technical features:

Supports C-band (1528-1561nm) and extended OSC band (1480-1520nm)

Main optical channel insertion loss ≤ 1.0dB, OSC channel insertion loss ≤ 1.5dB

OSC channel isolation ≥ 65dB, the highest in the FIU series

Supports IEEE 1588v2 clock synchronization without the need for additional testing or delay compensation

Extremely low polarization related loss (main light<0.1dB, OSC<0.15dB)

Application suggestion:

This board is a special FIU component for high-precision time synchronization networks in the OSN 9800 wavelength division system, particularly suitable for scenarios that require 1588v2 clock synchronization and extremely high OSC channel reliability, such as 5G mobile bearer networks, high-value dedicated line transmission systems, etc. When deploying, the advantages of its 1588v2 clock support and ultra-high isolation should be fully utilized, combined with the iMaster NCE intelligent control system, to build a high-precision, highly reliable, and monitored intelligent optical layer network. For conventional scenarios that do not require a 1588v2 clock, standard FIU cards such as TN13FIU/TN14FIU are more cost-effective choices.
