## Content

## In Short
- MetroFibre has reaffirmed its Mplify Carrier Ethernet for Business certification.
- The certification covers six Carrier Ethernet services used by enterprise and wholesale connectivity buyers.
- Testing is run by Iometrix, using MEF 91 requirements for consistent performance.

## What Happened
[MetroFibre](/metrofibre) has confirmed it still holds Mplify Carrier Ethernet for Business certification across six certified services. These services are E-Line, Access E-Line (A EPL), Access E-Line (A EVPL), Transit E-Line, E-LAN, and E-Tree.

Carrier Ethernet is a business-grade way to deliver network links over Ethernet, the same networking standard used inside most offices and data centres. In practice, it is often used for connecting branches, linking to cloud providers, and connecting one network operator to another.

Mplify Carrier Ethernet for Business is the new name for the MEF 3.0 Carrier Ethernet certification. Mplify, previously known as MEF, refreshed the programme and added a maintenance process so certifications stay current over time.

MetroFibre said the rebrand does not change its technical capabilities or requirements. The reaffirmation is meant to show continued alignment with global Carrier Ethernet standards and to give buyers a clearer benchmark for service performance.

The certification tests are managed by Iometrix, Mplify’s accredited test partner. Services are validated against MEF 91 and MEF 91.0.1 requirements, using defined traffic profiles and standard performance targets. That aims to make service behaviour predictable across different providers.

## Why It Matters
For enterprise customers, certifications like this act as a shorthand for expected network performance. That includes reliability, predictable latency, and interoperability, which means different networks can connect and work together without custom work.

This matters most for regulated or risk-sensitive sectors like financial services, where buyers often require third-party validation in procurement. It can also help wholesale connectivity buyers compare like-for-like services when choosing a fibre or metro Ethernet provider.

In South Africa’s business connectivity market, standards-based certification can be a differentiator. It signals that a provider can interconnect cleanly with global carriers and large networks, not just provide last-mile fibre.
