SG8050 GPON/EPON ONU – 4×GE, WiFi 5, 2×USB

Description

Overview

The SG8050 GPON/EPON ONU is a WiFi 5 optical network unit built for busy homes and small businesses that need many wired and wireless devices online at once. It terminates a single SC PON uplink and combines four gigabit Ethernet ports, dual USB ports and dual-band WiFi in one desktop unit, so the whole subscriber LAN sits behind a single fibre drop.

It accesses mainstream GPON and EPON OLTs and is tested for interworking with Fiberhome AN5516, ZTE C220/C300/C320/C600 and Huawei MA5600/MA5680/MA5800 platforms, so it can be dropped into an existing access network without changing the OLT side. Bridge, router and bridge/router mixed modes are supported together with NAT, ALG, UPnP, DMZ, DHCP/DHCPv6, PPPoE, static IP, 4K VLAN and IPv4/IPv6 dual stack, while WEB, TELNET, CLI, OAM, OMCI and TR069 cover remote management, provisioning and diagnostics.

The unit measures 205 × 136 × 24 mm, weighs under 250 g without its adapter, runs on 12 V 1.5 A and consumes less than 12 W. Front indicators cover PWR / PON / LOS / 5 GHz WiFi / 2.4 GHz WiFi / LAN1-4 / WPS / USB1-2, and an operating range of −5 °C to +45 °C at 10 % to 90 % non-condensing humidity suits desktop or cabinet installation in subscribers’ premises.

Deployment Scenarios

• FTTH access for high-end homes with four wired devices plus a growing number of wireless clients
• SMB and SOHO sites that need a 4-port gigabit switch, WiFi and shared USB storage in one box
• MDU and small-office installations using GPON or EPON OLTs from Fiberhome, ZTE or Huawei
• Hospitality and campus networks — guest houses, offices and business parks — that reuse an existing PON infrastructure
• Bulk ISP rollouts that need OMCI / TR069 remote provisioning, auto-configuration and auto firmware upgrade
