Innovative distribution point unit (DPU) solutions from DZS brings fiber-like connectivity to MDUs and residential markets where fiber is not economical or viable.

The Missing Link
 

Fiber-to-the-Home (FTTH) deployments have been generating great excitement amongst broadband users, promising amazing, consistent, high-speed, low-latency services. However, many FTTH deployments cannot reach or connect all customers within a deployment area, for several reasons, including expensive last-hop deployment costs, difficulties in obtaining access to premises, historical/architectural building preservation constraints, or complex Multi-Dwelling Unit (MDU) agreements.

In response to these challenges, operators around the world are adopting a Fiber Extension strategy to provide ultra-fast broadband, utilizing Gfast technology to deliver fiber-like speeds to dwellings over the last-hop copper infrastructure already in place; a cost-efficient alternative to a full-fiber deployment.

This efficient and effective Fiber Extension strategy consists of a reverse-powered Distribution Point Unit (DPU), that is linked to the existing copper line, and powered by an in-home Network Termination Device (NTD).

Flexible Deployment

A large-scale Gfast rollout requires DPUs that can be easily deployed in any environment. DZS’ DPUs can be deployed wherever it is needed – on a pole, on a wall, on a strand, in a pit, down a manhole, or in the basement of an MDU. Different deployments also require different port counts. A single dwelling is different to an MDU, and should be treated as such. DZS DPUs are available in a range of port-counts that provide the flexibility to optimize deployment to SDUs and MDUs in low, medium and high-density zones.

Silent, energy-efficient passive cooling design withstands a wide temperature range from -20°C to +70°C. Fully sealed waterproof outdoor housing with surge protection provides enhanced reliability even in the toughest conditions.

Simplified Installation Process

DZS Gfast Fiber Extension solutions have been carefully designed for efficient and simple installation to optimize deployment time and minimize cost. As world leaders in reverse-powered DPUs, our solution eliminates the significant costs and delays associated with preparing and connecting AC power at the installation location. DZS’ Installation Assistant is an easy to use, portable, battery-operated field tool compatible with all DZS DPUs. Proven in the field, our intelligent installation tools enable fast and efficient registration and birthing of DPUs.

A Focus on Interoperability

Designed with seamless network management in mind, DZS DPU’s and NTD’s are made to present to the network like an existing ONT in a fiber network. This eliminates the need to invest in new IT and management infrastructure usually required in the introduction of new technology.

OMCI Managed for Simple Integration

DZS DPUs can be managed entirely via OMCI, enabling registration, configuration and assurance entirely via your existing OLT Element Management System (EMS).

The DPUs feature advanced management capabilities with support Netconf/YANG, offering full remote device management and troubleshooting by using a Persistent Management Agent Aggregator (PMAA).

Designed to Deliver Fiber-Like Speeds

Designed to deliver fiber-like speeds to end-users via a cost-effective, easy-to-deploy method, especially in scenarios where deploying the final fiber segment is difficult, expensive or impractical. The DZS G.Fast DPU range acts as a fiber-extender, delivering gigabit-class symmetrical services over the existing lead-in infrastructure.

G.Fast 212MHz provides aggregate speeds up to 2Gbps, enabling the delivery of fiber-equivalent gigabit services over last-mile infrastructure.
