FTTx Battery Backup Devices
FAQs
An FTTx Battery Backup Unit (BBU) provides emergency power to essential fibre network devices such as Optical Network Terminals (ONTs), routers, and WiFi gateways during mains power outages. It ensures uninterrupted broadband and voice connectivity for up to an hour, depending on the load and configuration. These units are ideal for FTTH (Fibre-to-the-Home) and FTTB (Fibre-to-the-Building) installations where network reliability and uptime are critical.
Most FTTx Battery Backup Units provide up to one hour of backup when powering up to three connected devices such as an ONT, router, and VoIP phone. Actual runtime varies depending on:
- Device power consumption (total wattage draw).
- Battery health and capacity.
- Ambient temperature and usage frequency.
Some models allow battery expansion or replacement to extend runtime or maintain long term reliability.
You can connect up to three low power network devices typically found in home or small business fibre setups, including:
- Optical Network Terminals (ONTs).
- WiFi routers or gateways.
- Voice over IP (VoIP) adapters or telephones.
FTTx BBUs are designed to deliver stable DC power output, ensuring that these devices continue to operate seamlessly during a power failure, keeping both internet and phone services active.
Benefits include:
- Uninterrupted service, maintains connectivity for fibre broadband and VoIP calls during outages.
- Customer satisfaction, reduces downtime and service disruption.
- Equipment protection, provides regulated power output and helps prevent sudden shutdowns or voltage fluctuations.
- Easy installation, compact, plug-and-play design suitable for home or office wall mount setups.
- Sustainability, many units use rechargeable lithium-ion or sealed lead acid batteries, with replaceable packs to extend lifespan.
