The Fiber Net Modem Myth: What You Really Need
Fiber uses an ONT, not a modem: Your fiber connection works by translating light signals with a device called an Optical Network Terminal (ONT), which is why your old cable modem isn''t
Why not use fiber optic cable for the router s LAN port
Home / Why not use fiber optic cable for the router s LAN port
LAN cables, while offering lower bandwidth and higher latency than fiber optics, provide adequate performance for most applications and are typically more cost-effective. Fiber optics use light to transmit data, which allows for much higher frequency and, consequently, larger data capacities. This is a significant advantage for environments requiring high-speed data transfer, such as data. Many people ask the same question: Can you use a fiber optic cable with an RJ45 port? The short answer is no - RJ45 connectors are designed for electrical Ethernet signals, while fiber optics transmit light pulses through glass or plastic. org/wiki/Network_interface_device#Optical_network_terminals Some ISP's use ONT's that have integrated routers - its easier for THEM but it gives them more control over. Both fiber optic and copper ethernet cables have unique characteristics and compelling advantages and disadvantages but they are generally used to support the same communication protocol which is the Ethernet standard (IEEE 802.
