Extend Fiber Broadband Over Existing Copper Infrastructure

Expanding fiber broadband to every subscriber is not always practical due to deployment costs, building access limitations, or existing infrastructure constraints. Fiber Extension solutions help service providers overcome these challenges by leveraging existing copper wiring to deliver fiber-like broadband performance while reducing the cost and complexity of last-mile deployments.

Zhone Fiber Extension solutions combine Distribution Point Units (DPUs) and Network Termination Devices (NTDs) to help operators extend high-speed broadband services to residential and multi-dwelling environments. Alliance Corporation works with Zhone to help organizations evaluate Fiber Extension solutions that support cost-effective broadband expansion while maximizing existing infrastructure investments.

What Is Zhone Fiber Extension?

Zhone Fiber Extension is a portfolio of Gfast-based solutions designed to deliver fiber-like connectivity over existing copper infrastructure. The portfolio includes Distribution Point Units (DPUs), Network Termination Devices (NTDs), and supporting accessories that enable service providers to extend broadband services into locations where full fiber deployment may not be economical or practical.

Designed for residential neighborhoods, multi-dwelling units (MDUs), and other challenging deployment environments, Fiber Extension solutions help operators expand broadband coverage while leveraging existing copper wiring for the final connection to the subscriber.

Common applications include:

• Fiber-to-the-Building (FTTB)
• Fiber Extension deployments
• Multi-Dwelling Unit (MDU) broadband
• Residential broadband services
• Last-mile broadband connectivity
• Gfast broadband deployments
• Campus and in-building connectivity
• Broadband network expansion
• Fiber infrastructure optimization
