Functional Characteristics Technical Description System Value

Main optical channel multiplexing combines the main optical channel signal with the optical monitoring channel (OSC) signal 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

Extended OSC channel processing supports 1480-1520 nm extended OSC band, providing more flexible monitoring channel configuration options separated from the main optical signal transmission, compatible with different OSC wavelength planning requirements

Ultra high OSC channel isolation degree OSC channel isolation degree ≥ 40 dB, far higher than the conventional FIU board& # 39;s 12dB isolation degree, effectively preventing crosstalk between OSC channel and main optical channel, ensuring reliable transmission of network management monitoring information, especially suitable for long-distance, high-power systems

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

7.Application scenarios

Core Value of Application Scenario Deployment Method

Ultra long distance backbone transmission is deployed in amplification stations along thousands of kilometers of backbone network lines.The OSC channel for processing high-power signals has ultra-high OSC isolation (≥40dB) to ensure that monitoring channel signals are not interfered with under the background of high-power main optical signals, ensuring reliable transmission of network management information

High OSNR system nodes are deployed at critical nodes that require precise optical layer monitoring, utilizing MON ports for online monitoring to achieve uninterrupted business OSNR, optical power, and spectral monitoring, providing data support for network optimization and fault diagnosis

The ROADM node line side is deployed as a reconfigurable optical add/drop multiplexer on the line input/output side of the ROADM node, providing standard optical interfaces and high isolation OSC processing capabilities

Multi span submarine cable systems are used as standard FIUs in submarine cable systems, processing extended OSC bands (1480-1520nm) compatible with different OSC wavelength plans, and providing ultra-high isolation to meet the high power requirements of submarine cable systems

The hybrid OSC wavelength network is deployed at the junction of different OSC wavelength planning in the network to extend the OSC band coverage to the full range of 1480-1520nm, and can flexibly adapt to different OSC wavelength systems such as 1500nm or 1480nm

8.Maintenance and ordering information

Project Information

Component code TN16FIU

Ordering instructions: Please confirm the OSC wavelength range (1480-1520nm) and ultra-high isolation requirements (≥ 40dB) when placing an order

On site operation supports hot plugging, and anti-static wrist straps should be worn during operation.Pay attention to cleaning the fiber optic connectors

The optical power output from the MON port is approximately a small proportion of the total signal, and it is necessary to confirm the input range of the spectrometer or monitoring unit when using it

After testing and verifying installation, insertion loss testing, OSC channel connectivity testing, and isolation verification are required

As a highly isolated special FIU board, spare parts management recommends configuring spare parts at key locations such as ultra long distance backbone nodes and submarine cable systems

TN16FIU is an enhanced fiber optic interface unit board designed specifically for ultra long distance and high-power DWDM systems on the OSN 9800 platform.Based on the standard FIU functionality, it achieves a revolutionary improvement in OSC channel isolation (≥ 40dB), solving the pain point of traditional FIU in high-power systems where OSC channels are susceptible to interference.

Core values and positioning:

Ultra high OSC channel isolation: The OSC channel isolation is ≥ 40dB, much higher than the conventional FIU's 12dB, which can effectively prevent the interference of high-power main optical signals on the monitoring channel and ensure the reliable transmission of network management information in ultra long distance backbone networks and submarine cable systems.

Extended OSC band support: The OSC wavelength range covers 1480-1520nm, compatible with different OSC wavelength plans such as 1500nm and 1480nm, providing maximum flexibility in OSC configuration.

Designed for harsh scenarios: Especially suitable for scenarios such as thousands of kilometers of backbone networks, submarine cable systems, high OSNR systems, etc.that require extremely high reliability of monitoring channels, it is the core component of building a highly reliable optical layer monitoring network.

Online monitoring capability: Provides optical performance monitoring capability that does not affect business through the MON port, providing key data entry points for preventive maintenance and dynamic optimization of the network.

Technical features:

Supports C-band (1529-1561nm) and extended OSC band (1480-1520nm)

OSC channel isolation ≥ 40dB, improved by more than 28dB compared to conventional FIU

Provide dedicated MON monitoring port for external spectral analysis equipment

Extremely low polarization related loss (<0.2dB), friendly to high-speed modulation signals

Power consumption of 6.0W, equivalent to TN15FIU

Application suggestion:

This board is a special FIU component for ultra long distance and high-power transmission in the OSN 9800 wavelength division system, particularly suitable for scenarios that require extremely high OSC channel reliability, such as:

Thousands of kilometers of backbone network

Line amplification station of submarine cable system

Core nodes with high OSNR requirements

Hybrid networks with different OSC wavelength planning

When deploying, the advantages of its ultra-high isolation and extended OSC band should be fully utilized, combined with the iMaster NCE intelligent control system, to build a highly reliable, monitored, and optimized intelligent optical layer network. For scenarios with conventional transmission distances or low requirements for OSC isolation, TN13FIU/TN14FIU/TN15FIU is still a more cost-effective choice.
