Power: Built‑in AC power supply (100‑240V), dual‑power option available.
Benefits of 2‑Port GPON OLT
Balanced Capacity for Growing Networks
Two GPON ports offer a sweet spot for small ISPs and campus deployments – supporting up to 256 subscribers (at 1:128 split) while keeping hardware costs low.
Flexible Uplink and Compact Form Factor
With 4 Gigabit uplink ports, you can aggregate upstream traffic efficiently. The 1U chassis fits standard racks or can be placed on a desktop, saving space in small equipment rooms.
Easy Management and Zero‑Touch ONU Provisioning
WEB/CLI management, combined with auto‑discovery and auto‑configuration of ONUs, simplifies setup and maintenance – reducing operational costs.
Engineering Applications 2‑Port GPON OLT
Small‑Scale ISP and Rural FTTH
Deploy in villages or small towns to connect up to 256 homes via passive optical splitters – a cost‑effective alternative to larger OLTs.
Campus Buildings and Multi‑Tenant Offices
Provide fiber connectivity to each floor or tenant in a single building, supporting high‑speed internet, IPTV, and VoIP services.
Remote Work and Edge Deployments
Perfect for remote work hubs, construction sites, or temporary offices – quick to deploy and simple to manage.
