FAQ
What exactly *is* a fiber optic modem, and how is it different from a traditional cable modem?
A fiber optic modem, often referred to as an Optical Network Terminal (ONT), converts the optical signal transmitted over fiber optic cables into an electrical signal your router and devices can understand. Unlike traditional cable modems which use coaxial cables and radio frequency (RF) signals, fiber optics utilize pulses of light to transmit data. This fundamental difference in transmission medium is the core distinction. Cable modems share bandwidth with numerous neighbors in a node, leading to potential slowdowns during peak hours, while fiber offers dedicated bandwidth directly to your home.
The performance difference is significant. Fiber optic connections generally offer much higher speeds – often gigabit speeds – and lower latency compared to cable. Data from the FCC’s 2023 Broadband Deployment Report shows fiber consistently delivers advertised speeds more reliably than cable. Furthermore, fiber is less susceptible to interference from electrical sources, resulting in a more stable and reliable connection. While a cable modem modulates a signal, an ONT demodulates light, hence the different terminology and function.
Do I need a separate modem *and* router for fiber internet, or can I get a combined unit?
Generally, you will need both a modem (ONT) and a router, though combined “gateway” units are becoming increasingly common. The ONT is provided by your Internet Service Provider (ISP) and handles the conversion of the fiber optic signal. The router then distributes that signal to your devices via Wi-Fi and Ethernet. While some ISPs offer a combined ONT/router unit, these are often locked down and offer limited customization options.
Choosing separate devices provides greater flexibility and control. You can select a router with features tailored to your needs – such as advanced security, mesh networking capabilities, or Quality of Service (QoS) settings – without being limited by the ISP’s hardware. Independent testing by sites like Wirecutter consistently shows that standalone routers often outperform combined gateway units in terms of Wi-Fi range and speed.
