What is the OLT?

An optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network (From Wikipedia).

This image tells you where the OLT is in an EPON.

In short, OLT is like a commander, commanding each ONU soldier, to provide a low-cost and high-speed communication service, to connect life more closely on the planet, and technology to change life.

What is the Huawei SmartAX EA5800?

The Huawei SmartAX EA5800 Series is the full-service distributed OLT, building green, ultra-broadband, and intelligent aggregation access networks. (See all models: Huawei SmartAX EA5800 Series OLT)
