Ubiquiti WAVE-FIBER-ONU-5 60 GHz Wireless Bridge

Ubiquiti WAVE-FIBER-ONU-5 GPON Optical Network Unit

Overview

The Ubiquiti WAVE-FIBER-ONU-5 is a GPON (Gigabit Passive Optical Network) optical network unit designed for fiber-to-the-premises (FTTP) deployments requiring reliable high-speed connectivity. This unit delivers 2.5 Gbps downlink and 1.2 Gbps uplink throughput over distances up to 20 km, making it suitable for residential, small business, and enterprise last-mile fiber network architectures. The integrated 2.5 GbE port provides direct connectivity to customer premises equipment (CPE), switches, or wireless access points without requiring separate media conversion.

Key Features

• 2.5 Gbps Downlink / 1.2 Gbps Uplink Performance: Asymmetric bandwidth allocation optimized for residential and small-to-medium business broadband delivery
• Extended Reach GPON: Operates reliably at distances up to 20 km from the optical line terminal (OLT), reducing the need for intermediate optical amplification in rural and sprawling deployments
• Single 2.5 GbE Port: Native Multi-Gigabit Ethernet interface eliminates the bottleneck of traditional Gigabit ports and supports future bandwidth scaling
• GPON Compliance: Standards-based GPON implementation ensures interoperability with compatible optical line terminals and network infrastructure
• Compact Form Factor: Low-profile design suitable for wall-mount or DIN-rail installation in customer premises, network cabinets, or distribution enclosures
• Plug-and-Play Deployment: Simplified provisioning reduces on-site configuration time and training requirements for field technicians

Technical Specifications

The WAVE-FIBER-ONU-5 operates at layer 2 (data link) and provides standard GPON framing and protocol support. Downlink capacity of 2.5 Gbps is delivered over a single wavelength in the downstream direction, while the 1.2 Gbps uplink utilizes time-division multiplexing (TDM) on the return path. The 20 km maximum optical reach is measured under standard single-mode fiber (SMF) conditions and typical insertion loss budgets, allowing deployment in both urban and extended geographic service areas.

Integration & Compatibility

The WAVE-FIBER-ONU-5 is designed to terminate GPON services delivered by compatible optical line terminals (OLTs) and fiber access networks. The 2.5 GbE port is compatible with standard Ethernet switching infrastructure, managed switches with VLAN support, and multi-gig capable network interface cards. Installation integrators should verify OLT vendor support and GPON profile alignment (ITU-T G.984) prior to deployment to ensure service activation and QoS provisioning. The unit supports standard GPON management interfaces for monitoring and configuration.

Package Contents

The Ubiquiti WAVE-FIBER-ONU-5 ships as a 5-pack, allowing integration teams and service providers to deploy multiple units across customer sites, pilot programs, or phased network expansion. This bundled approach reduces per-unit costs and simplifies inventory management for regional deployment initiatives.

Jerry Tildsen

I evaluated the Ubiquiti WAVE-FIBER-ONU-5 during the planning phase of a fiber-to-the-premises project serving mixed residential and small-business districts. This GPON ONU delivers solid performance metrics for cost-effective last-mile fiber delivery, and the 2.5 GbE port eliminates a common bottleneck seen in earlier Gigabit-only implementations.

Technical Highlights:

• Asymmetric Bandwidth: The 2.5 Gbps downlink and 1.2 Gbps uplink split reflects real-world residential usage patterns where download demand typically exceeds upload capacity. This is a practical design choice rather than a limitation.
• Extended Reach: The 20 km GPON reach significantly reduces the need for intermediate optical regeneration equipment in rural and suburban deployments, lowering infrastructure cost per subscriber.

Deployment Considerations:

• Verify OLT compatibility and GPON profile support before mass deployment. Different GPON vendors implement slightly different overhead and management schemes.
• Plan fiber routing and splitter placement to stay within the 20 km optical budget. Use standard insertion loss calculations to confirm reach in your specific fiber plant.

The WAVE-FIBER-ONU-5 is a reliable choice for integrators building FTTP networks that require standards-based interoperability and multi-gig future-proofing. The 5-pack format is well-suited for pilot deployments and phased customer rollouts.
