Our Approach

Efficiency by design, not afterthought

Our network is built around technologies that inherently consume fewer resources to deliver more capacity.

Efficient Optical Transport

DWDM technology carries 80+ independent channels over a single fiber pair, dramatically reducing the infrastructure footprint per unit of capacity. One strand of glass replaces racks of copper and active electronics.

Smart Capacity Planning

Traffic engineering and intelligent routing minimize over-provisioning and energy waste across the network. Capacity is added where needed, avoiding idle infrastructure running at full power.

Responsible Equipment Lifecycle

Partnership approach to equipment recycling and responsible disposal of end-of-life network hardware. We prioritize vendors with established take-back and recycling programs.

Shared Infrastructure

Colocation and shared fiber routes reduce duplicate infrastructure builds, lowering the environmental footprint for all participants. Shared duct systems mean fewer civil works and less disruption.

Energy Efficiency

Power consumption per Gbps — technology comparison

Watts per Gbps (lower is better)

Traditional Copper~5 W per Gbps
5W/Gbps
Microwave Links~3 W per Gbps
3W/Gbps
Modern DWDM Fiber~0.5 W per Gbps
0.5W/Gbps

DWDM fiber carries up to 10× more capacity per watt compared to microwave links — and up to 90% less energy per Gbps compared to legacy copper infrastructure.

Infrastructure footprint comparison

Copper
8 cables · 5W/Gbps each
DWDM Fiber
1 fiber · 80+ channels · 0.5W/Gbps

A single DWDM fiber pair carries the equivalent of 80+ wavelengths, each up to 400G — replacing hundreds of individual copper or microwave links.

Passive optical infrastructure means no powered equipment in the field — only glass and light, with no standby power draw outside facility walls.

Our Commitments

Operational sustainability principles

Realistic, measurable commitments — no green-washing, no fabricated certifications. These are the operating principles we hold ourselves to.

Continuous monitoring of power consumption across all Points of Presence

Prioritizing energy-efficient equipment in all procurement decisions

Supporting industry initiatives for sustainable telecommunications

Transparent reporting on network energy metrics to stakeholders

Selecting colocation facilities with documented PUE targets

Reducing redundant active infrastructure through passive optical architecture

Data Center Partnerships

Choosing facilities that share our values

Sofia Connect co-locates its Points of Presence in third-party data center facilities across Southeast Europe and beyond. We factor sustainability performance into our facility selection and review process.

Efficient Cooling

We prioritize facilities that employ free cooling (adiabatic or direct air) where the local climate permits, significantly reducing mechanical cooling overhead.

PUE Monitoring

Power Usage Effectiveness is a core criterion in our colocation partner selection. We track PUE metrics at each PoP facility and factor them into renewal and expansion decisions.

Renewable Energy Procurement

Where commercially viable, we favor data center partners who procure electricity from renewable sources or participate in green tariff programs.

Typical PUE targets we look for in partner facilities:

Best-in-class:< 1.2
Good:1.2 – 1.4
Industry avg.:~1.6

LED-based equipment status monitoring

Modern network equipment uses LED indicators for port and system status — consuming milliwatts rather than the standby power of older display technologies. Combined with out-of-band management over low-power serial connections, our equipment monitoring infrastructure adds minimal to the overall power footprint of each PoP.
