Standard fiber optic cables transfer data somewhere between 10Mbps and 10Gbps, but a single strand of fiber optic cable has been proven to be able to carry data at up to an extremely fast 100 Tbps (Terabits per second). In fiber optic cable that means that light is either on or off, blinking extremely fast, representing 0 when the light is off and 1 when the light is on. As mentioned above, data is represented by a combination of 1s and 0s. Single-mode cables use laser light to send signals, while multi-mode cables use light-emitting diodes (LEDs) to send signals. That can be a security and privacy risk.Īlso, there are inherent limits to how fast data can be transmitted over copper wires that are much lower than the inherent limits on the transmission of data using light (i.e., fiber optics). Because it uses electrical signals, it’s both vulnerable to electromagnetic interference and data transmitted this way is vulnerable to being intercepted by hackers at the hardware level. In reality, copper wires transmit data pretty directly - a combination of 1s and 0s represents all data, and in copper wires, that means a variation of voltage.Įthernet does have its drawbacks. While this is lightning fast, fiber optics are still much faster.Įthernet cables send data through electrical impulses, and most Ethernet cables fall under Cat 5 - which uses eight individual 24-gauge copper group wires into four pairs inside the cable. Currently, Cat 6 Ethernet cables can carry up to a massive 10Gbps. Now, however, “fast Ethernet” offers rates of up to 100Mbps, while Gigabit Ethernet can deliver speeds of a hefty 1000Mbps. There was a time when Ethernet speed had a 10Mbps (Megabits per second) limit.
