ONT Product Information Guide
1.1 ONT and MDU general descriptions of features and 
functions
The ONT and MDU are part of a family of products that provide “last mile” 
broadband access solutions. The products work together to form a fiber access 
network capable of delivering high quality voice, video, and data services to both 
single-family and multi-dwelling residential subscribers. 
The Alcatel-Lucent ONT and MDU products are edge devices that use GPON 
technology to extend a fiber optic cable from a P-OLT shelf at a CO to a subscriber 
residence, including single-family residences, multi-dwelling residences such as an 
apartment building, and small office applications.
The ONT product family consists of the following:
• Packet Optical Line Terminations (P-OLTs)
• ONTs that include:
• business focused models
• residential models (indoor, outdoor)
• multi-dwelling unit models (MDU)
• Element Management System (EMS), including: a simple web-based 
management system and a sophisticated network management system

and provides interfaces between the network and the gigabit passive optical network 
(GPON).
