MON LC/UPC 1 online monitoring port can output a small amount of optical signals to a spectral analyzer or spectral analysis unit to monitor the spectral and optical performance of the composite signal without interrupting business

3.Core functional characteristics

Functional Module Technical Description System Value

Optical signal amplification compensates for fiber transmission loss by amplifying the power of input optical signals in the C-band (1529-1561 nm), supporting different spans of wireless relay transmission

The TN13OAU101 version supports a high gain range of 20 dB to 31 dB and can continuously adapt to longer spans or higher loss links, reducing the need for relay station construction

Dual mode gain/power locking supports two modes: gain locking and power locking

Gain lock mode: The board gain is adjustable and the actual gain value can be queried (default mode)

Power locking mode: suitable for scenarios with only false light locking, flexibly adapting to different working scene requirements to ensure stable output

Transient control technology has a built-in fast response circuit to deal with sudden changes in input power on multiple wavelength channels, ensuring stable remaining channel power and uninterrupted business operations

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

Real time monitoring of pump laser to detect parameters such as pump drive current, back current, cooling current, pump temperature, etc.Monitoring of pump source health and warning of potential faults

Real time monitoring of environmental temperature on the board to prevent overheating and damage, ensuring long-term stability

Real time detection and reporting of optical power, as well as reporting of alarms and performance events related to the board, to quickly locate faults and achieve preventive maintenance

6.Application scenarios

Core Value of Application Scenario Deployment Method

Long distance trunk transmission is deployed in line amplification stations (OLAs) to compensate for inter segment fiber losses, significantly extending transmission distance and reducing the construction of relay stations

The metropolitan core ring network serves as a post amplifier (BA) or pre amplifier (PA) in the metropolitan core ring to enhance the coverage area of the metropolitan network and reduce the cost per bit

Data center interconnection serves as a line amplifier in DCI links to ensure high-capacity, long-distance transmission between ultra large data centers

Different cross segment networking support systems enable flexible adaptation to multiple network topologies and geographical environments for wireless relay transmission in different cross segment fiber optic links

Ordering instructions: Please confirm the gain version (20-31dB) and monitoring port configuration 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

After testing and verifying installation, gain calibration, power testing, and monitoring function verification are required

Spare parts management, as the core board of optical amplification, is recommended to configure spare parts at critical nodes in the network

Core Summary:

TN13OAU1 is a C-band high gain optical amplification unit board in the OSN 9800/8800 platform.As an enhanced gain version of the OAU1 series (20-31dB), it provides a higher gain range than TN12OAU1 and is suitable for transmission scenarios that require longer spans or higher loss compensation.

Core values and positioning:

High gain support: 20-31dB gain range, which can meet the needs of longer cross segment transmission and reduce the construction of relay stations.

Dual mode locking: Gain locking and power locking are dual modes, flexibly adapting to different working scenarios.

Intelligent monitoring: Online monitoring interface and comprehensive pump/environment monitoring function provide data support for preventive maintenance.

Transient control: Quickly respond to sudden changes in input power, ensuring stability of multi wavelength services.

Comparison with TN12OAU1:

Characteristics TN12OAU1 TN13OAU1 (OAU101)

Working band extension C-band (1528.8-1567.6nm) C-band (1529-1561nm)

Gain range 15-28 dB 20-31 dB (higher gain)

Typical power consumption 12 W 12 W

Application positioning extension C-band mid-range amplification C-band long-range/high loss amplification

Application suggestion:

This board is an optical amplification component for C-band long-distance transmission in the OSN 9800 wavelength division system, especially suitable for transmission scenarios that require high gain ( > 28dB), such as ultra long span trunk lines, high loss link compensation, etc. During deployment, it is necessary to set the gain reasonably based on the link loss and combine it with the network management system to achieve performance monitoring of the optical layer. For scenarios that require the extension of the C-band (supporting 96 waves @ 50GHz), TN12OAU1 is a more suitable choice.
