3.Core functional characteristics

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

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

Optical layer ASON supports automatic switching of optical layers, providing basic support for intelligent optical networks

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

7.Application scenarios

Core Value of Application Scenario Deployment Method

The 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 demultiplexing of the main optical signal and OSC, and is the standard optical layer interface of the wavelength division system

The optical amplification station is located in the line amplification station and is used in conjunction with the optical amplifier to provide access/drop for monitoring channels, ensuring that the remote supply station can still be monitored by the 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

8.Maintenance and ordering information

Project Information

Component code TN14FIU

Ordering instructions: Please confirm the OSC wavelength range (1480-1520nm) and isolation requirements 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 and OSC channel connectivity testing 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

Core Summary:

TN14FIU is a C-band fiber optic interface unit board in the OSN 9800 platform.As the basic component of the optical layer, it undertakes two core functions: multiplexing and demultiplexing of the main optical channel and the optical monitoring channel, as well as online optical performance monitoring.

Core values and positioning:

System optical interface standard component: It connects the internal optical path of the device with the external fiber optic line, and processes the out of band OSC channel.It is an indispensable optical layer interface board in DWDM systems.

Online monitoring enabler: 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.

Extended OSC wavelength support: The OSC wavelength range is extended to 1480-1520nm, covering a wider monitoring channel band compared to TN13FIU (1500-1520nm).

Application suggestion:

This board is a standard configuration component of the OSN 9800 wavelength division system, suitable for C-band DWDM systems. Of particular note is its extended OSC wavelength range (1480-1520nm), which gives it an advantage in scenarios that require more flexible monitoring channel configurations. It is recommended to fully utilize the MON monitoring port at key nodes in the network, connect the optical performance monitoring unit, and build a smart optical layer that can be monitored and optimized.
