Functional Characteristics Technical Description System Value

Extended C-band signal amplification supports input optical signals within the wavelength range of 1528.8 nm to 1567.6 nm, supporting full band signal amplification in the extended C-band to meet high-capacity transmission requirements

Pump light multiplexing/splitting combines or splits business signal light, RPC pump light, ROP pump light, and high-power pump light emitted by the ERPC board to achieve effective coupling between pump light and signal light, thereby improving amplification efficiency

Distributed online amplification achieves long-distance, broadband, and low-noise signals.Compared with centralized EDFA, distributed online amplification can significantly improve the optical signal-to-noise ratio (OSNR) and extend the transmission distance

Working mode selection supports pump power locking mode to ensure stable output power and adapt to different link conditions

The panel interlocking function panel provides interlocking switches, controls the power on/off of the module, and ensures the safety of operators by allowing the board to be plugged in and out, preventing live plugging and unplugging

The pump source shutdown control supports controlling the pump source switch through the LAS button on the panel for easy on-site maintenance and fault handling

6.Application scenarios

Table 7: Typical Application Scenarios

Core values and advantages of application scenario deployment methods

Deploying ERPC in fiber optic lines for ultra long distance backbone transmission provides distributed Raman amplification, which can significantly extend the distance of non electric relay transmission and reduce the construction of relay stations compared to pure EDFA solutions

The submarine cable/ultra long distance land trunk line adopts an enhanced backward pump configuration to maximize OSNR gain and meet the strict requirements of OSNR for thousands of kilometers of ultra long distance transmission

The deployment of Raman amplification with low noise characteristics in links where EDFA cannot meet the OSNR margin requirement for high OSNR can effectively improve the system's OSNR and support high-order modulation formats (such as 16QAM)

Upgrading old fiber optic links utilizes Raman amplification to enhance the transmission performance of aged fibers without the need for fiber replacement, thereby increasing system capacity and transmission distance and protecting existing investments

The extended C-band system serves as the core amplification unit in the newly built extended C-band system, supporting full band signal amplification and maximizing spectrum utilization

7.Working mode and configuration

Table 8: Pump Operating Mode Description

Applicable scenarios for work mode configuration methods

Forward pump light and signal light are transmitted in the same direction to provide gain at the front end of the fiber when the signal enters, which is suitable for specific link designs

The typical application mode of backward pump light and signal light reverse transmission (enhanced type) can effectively reduce the influence of pump noise on the signal and achieve better OSNR performance

Simultaneous configuration of bidirectional pump and forward/backward pump provides maximum gain and optimal noise performance in extreme long-distance scenarios

8.Security and protection mechanisms

Table 9: Security Protection Characteristics

Implementation method of protection mechanism and protection purpose

When the reflected light power is detected to be greater than 15 dBm, the laser is automatically turned off to prevent high-power reflection from damaging the laser or causing damage to the fiber end face

The power on/off and pluggable status of the panel interlock switch control module ensures the safety of operators and avoids live plugging and unplugging

LAS button control panel button directly controls the pump source switch for safe operation during on-site maintenance

Temperature protection board temperature detection and reporting, automatic adjustment or alarm when exceeding the limit to prevent overheating and damage, ensuring long-term reliability

9.Compatibility and configuration requirements

Table 10: System Compatibility Requirements

Specific description of the required category

Host platform compatibility is applicable to OSN 9800 series subracks that support TN cards

The software version requirement requires the device host software version to support the Raman amplification function and monitoring management of the board

Fiber types support multiple fiber types such as G.652, G.654A, G.654B, etc., and the gain characteristics vary on different fibers

The supporting board needs to be coordinated with the EDFA on the line side, the combiner/splitter, etc., to form a complete optical amplification scheme

Pump configuration selects forward/backward pump modes based on link requirements and conducts precise power planning
