3.Core functional characteristics

Functional Characteristics Technical Description System Value

Super C-band main optical channel multiplexing and demultiplexing processing of Super C-band (1524.50 nm~1572.06 nm) main optical channel signals to achieve efficient coupling of optical signals between fiber optic lines and equipment, supporting 120 wave @ 50GHz high-density systems

Optical monitoring channel processing combines and splits the optical monitoring channel (OSC), separates it from the main optical signal for transmission, and ensures the independence and reliability of the out of band monitoring channel, achieving uninterrupted business network management communication

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

Low insertion loss design optimizes optical path design to minimize signal insertion loss, reduce pressure on system optical power budget, and extend transmission distance

The high isolation main optical channel and OSC channel have excellent isolation characteristics to prevent inter channel crosstalk and ensure signal quality

4.Optical performance parameters

Interface/Channel Parameter Specification Remarks

The working wavelength range of the main optical channel is 1524.50 nm to 1572.06 nm in the Super C band, supporting 120 wave @ 50GHz systems

The working wavelength range of the optical monitoring channel is 1510 nm ± 10 nm (or 1625 nm ± 10 nm) standard OSC wavelength, which can be optionally selected

All ports have excellent return loss characteristics with optical return loss>40 dB, reducing reflection

Main optical channel insertion loss ≤ 1.5 dB IN-SYS OUT/SYS IN-OUT

OSC channel insertion loss ≤ 1.0 dB OSC IN-OUT

7.Application scenarios

Core Value of Application Scenario Deployment Method

The Super C-band DWDM terminal station is deployed on the line side of the OTM site, connecting the multiplexer/demultiplexer with the fiber optic line to achieve the multiplexing and splitting of the main optical signal and OSC, supporting 120 wave @ 50GHz high-density systems

Optical amplification station (OLA) is used in conjunction with optical amplifiers in line amplification stations to provide access/drop of monitoring channels, ensuring that remote supply stations can still be monitored by network management

ROADM nodes are deployed on the line input/output side of ROADM nodes as reconfigurable optical add/drop multiplexers, providing standard optical interfaces and OSC processing capabilities

Optical performance monitoring points are deployed at key nodes in the network, utilizing the MON port for optical performance monitoring to achieve uninterrupted OSNR, optical power, and spectral monitoring of services, providing data support for network optimization and fault diagnosis

The Super C+Super L evolution system, as the basic interface unit of the Super C band, lays the foundation for future expansion to C+L and supports smooth evolution to protect network investment

8.Maintenance and ordering information

Project Information

Component code TN12FIU (specific version such as TN12FIU01)

Ordering instructions: When placing an order, it is necessary to specify the OSC wavelength (1510nm/1625nm) and MON port 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

The optical power output from the MON port is approximately 2% 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 MON port coupling ratio verification are required

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