What is Low-Power Optical Transceivers (LPO)?

Linear Pluggable Optics (LPO) replace the DSP inside the optical module with linear analog components, shifting signal processing to the host ASIC.
This innovation delivers up to 30% lower power consumption, reduced latency, and simplified thermal management — perfect for high-density fabrics and AI workloads.

Why Choose Swedish Telecom Opto for LPO?

EU-tested – verified by European labs for performance and power.
Ultra-low power – efficient design for energy-constrained environments.
Host-ready – compliant with CEI-112G-LINEAR-PAM4 standards.
Fast EU delivery & support – logistics and invoicing within the EU.
White-label capable – your brand on proven, validated optics.

All LPO modules undergo independent validation in EU laboratories for power, signal integrity, and interoperability.
A downloadable test summary will be available upon final verification.

Frequently Asked Questions

How is LPO different from DSP-based optics?

LPO removes the DSP from the module, letting the host ASIC handle signal processing – resulting in lower power, lower latency, and simpler thermal design.

What hosts are compatible with LPO?

Switches and NICs supporting linear-drive interfaces (CEI-112G-LINEAR-PAM4) are compatible. We help confirm support per platform.

Can LPO and DSP modules coexist?

Yes, in the same network – but each link must be homogeneous (LPO↔LPO or DSP↔DSP).

Are the modules certified in the EU?

They’re tested in EU labs for power and signal integrity. A validation summary is available on request.

What’s the warranty?

12-month standard warranty with optional advance replacement.
