XPON MDU FAQ
Q1: What is an XPON MDU?
A: An XPON MDU (Multi-Dwelling Unit) is an optical access device designed for Fiber-to-the-Building (FTTB) and Fiber-to-the-Curb (FTTC) deployments. It connects an XPON network to multiple end users through Ethernet interfaces while supporting both GPON and EPON access modes.
Typical features include:
Adaptive GPON/EPON operation
Multiple Gigabit Ethernet ports
High-density user access
QoS support
Remote management
XPON MDUs are widely deployed in apartments, hotels, office buildings, campuses, and commercial complexes.
Q2: How does an XPON MDU work?
A: An XPON MDU receives optical signals from the Optical Line Terminal (OLT) through the PON network and converts them into Ethernet services for multiple users.
The basic workflow is:
The OLT transmits data through the GPON or EPON network.
The XPON MDU receives the optical signal.
The MDU converts optical data into Gigabit Ethernet services.
Multiple users connect through Ethernet ports to access broadband, voice, surveillance, or enterprise services.
This architecture simplifies FTTB deployment while supporting centralized network management.
