LambdaGain Pluggable Line System (PLS)
Ultra-Low-Power Optical Amplification for Greener Networks
A Cleaner, More Efficient Alternative to Traditional Line Systems
Telecom operators are expanding bandwidth faster than ever—but legacy optical line systems consume 80–300 W per site, generate significant heat, and add unnecessary embodied carbon. These oversized systems were designed for long-haul transport, not for compact metro and access deployments.
The LambdaGain PLS delivers the required amplification and link conditioning using a 2W pluggable module, enabling operators to build networks that are both high-performance and environmentally responsible.
Why PLS Is a Green Technology
>95% Lower Power Consumption
PLS uses just 2W, replacing traditional shelves that draw 100 W or more. This dramatically reduces electricity usage and Scope 2 emissions across the network.
Minimal Heat, Minimal Cooling Load
With almost no thermal output, PLS reduces HVAC demand—leading to additional indirect energy and emission savings.
Low Embodied Carbon
Traditional systems include metal chassis, large PCBs, fan trays, and power supplies. PLS replaces all of this with a single compact pluggable module, cutting upstream manufacturing and transportation emissions.
Reduced e-Waste
Fewer materials and no large housings mean smaller end-of-life footprint and reduced disposal impact.
Environmental Impact at a Glance
Factor | Traditional Line System | LambdaGain PLS |
Power Draw | 80–300 W | 2 W |
Cooling Required | High | Minimal |
Embodied Carbon | Heavy chassis + fans | Compact pluggable |
e-Waste | Large | Low |
Efficiency | Low for metro/access | Optimized for metro/access |
Sustainability Benefits for Operators
- Lower energy spend and reduced CO₂ emissions
- Smaller space and power requirements in POPs and cabinets
- Lower cooling and HVAC demands
- Better alignment with Net-Zero, Scope 2, and Scope 3 ESG goals
- A scalable, right-sized line system for metro access and regional DWDM links
The Greener Path Forward
With just 2–3 watts of power, LambdaGain PLS enables operators to:
- Reduce energy consumption
- Reduce GHG emissions
- Reduce material usage
