3.Core functional characteristics

Functional Module Technical Description System Value

Optical signal amplification is the core component of wavelength division systems for long-distance transmission, which amplifies the power of extended C-band DWDM signals, compensates for fiber transmission losses, and extends the transmission distance without electrical relays

Adjustable gain supports software adjustment of amplifier gain values (typical range 15-28 dB) to flexibly adapt to different loss optical amplifier segments, simplifying engineering planning and deployment

The OSC channel processing has built-in OSC multiplexing and demultiplexing function, which separates/merges the optical monitoring channel from the main optical signal to ensure independent transmission of out of band monitoring channels and achieve uninterrupted network management communication for business

Automatic gain control (AGC) monitors the input/output optical power in real-time, automatically adjusts the pump power to maintain a constant gain to cope with input power fluctuations, ensures stable output, and improves system robustness

Automatic Power Control (APC) supports a constant output power mode to maintain stable output power and adapt to different work scenarios, allowing for flexible selection of work modes

Gain Flattening: Built in Gain Flattening Filter (GFF) optimizes the EDFA gain spectrum to maintain power balance across all wavelength channels in multi-stage cascaded scenarios, avoiding OSNR degradation in some channels

The low-power design adopts a new generation of low-power pump technology and energy-saving circuits.The typical power consumption is only 12W, which is green and energy-saving, suitable for high-density deployment

Core Value of Application Scenario Deployment Method

Extended C-band trunk transmission supports 96 wave @ 50GHz high-density systems as standard amplification units at OTM/OLA sites, maximizing fiber spectrum utilization

The metropolitan core ring network serves as a post amplifier (BA) or pre amplifier (PA) at the metropolitan core nodes to enhance the coverage of the ring network and increase system margin

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

By combining hybrid amplification structures with Raman amplifiers (such as RPC), a high-performance hybrid amplification system is constructed to achieve better OSNR performance and longer transmission distances
