About Mebibit per second (Mibps)
A mebibit per second (Mibps) equals 1,048,576 bits per second — the binary IEC equivalent of megabit per second. It is approximately 4.9% larger than 1 Mbps. Mibps appears in network performance specifications written to IEC standards, and in operating system tools on Linux and some Unix variants that apply binary prefixes strictly. When a Linux system reports "ethtool: speed 100MiB/s", this distinction from 100 MB/s (decimal) matters in precise bandwidth budgeting.
A 100 Mibps figure represents 104.86 Mbps in decimal — about 5% more data. Network engineers use Mibps when exact binary calculations are required for buffer sizing.
About Terabit per second (Tbps)
A terabit per second (Tbps) equals 1,000 Gbps and is the unit of internet backbone and submarine cable capacity. Transoceanic fiber cables carry hundreds of terabits per second in aggregate across multiple wavelengths using dense wavelength-division multiplexing (DWDM). The global internet collectively carries several hundred Tbps at peak. Individual backbone router links at major exchange points operate at 100–400 Gbps, with Tbps links emerging in the largest facilities.
A single modern transoceanic submarine cable can carry 200–400 Tbps of aggregate capacity. Major internet exchange points like DE-CIX in Frankfurt peak at over 10 Tbps.
Mebibit per second – Frequently Asked Questions
When would I encounter mebibits instead of megabits?
Mainly in Linux system tools, IEC-compliant technical specifications, and some enterprise storage documentation. The iperf3 network testing tool can report in Mibps if configured to use binary units. Most consumer-facing software and ISPs use megabits exclusively.
How do I convert Mibps to Mbps?
Multiply by 1.048576. So 100 Mibps = 104.86 Mbps. To go from Mbps to Mibps, divide by 1.048576. At small values the difference is negligible, but at gigabit scales it can mean a meaningful amount of data.
Why does Linux sometimes use binary units for networking?
Linux kernel developers historically followed IEC recommendations to use binary prefixes where applicable. Some tools like dd and rsync default to binary (MiB/s) for disk operations. However, network-facing tools like ethtool and ip still use decimal Mbps because that is what the hardware reports.
Does the 5% difference between Mibps and Mbps matter in practice?
For casual use, no. For capacity planning and SLA compliance, yes. If a contract guarantees 100 Mibps and the provider measures in Mbps, the customer might get 100 Mbps (only 95.4 Mibps) and technically be short-changed. Data center SLAs should specify which unit system applies.
Is my ISP cheating me by using megabits instead of mebibits?
No — ISPs legitimately use decimal megabits because Ethernet and fiber standards are decimal. A "100 Mbps" plan genuinely delivers 100,000,000 bits per second. The confusion arises only when comparing with binary-unit tools. ISPs are not hiding anything; the two systems just coexist awkwardly.
Terabit per second – Frequently Asked Questions
How much data does the entire internet carry per second?
Global internet traffic peaks at roughly 1,000–1,500 Tbps (1–1.5 Pbps) as of 2026. This is growing at about 25% per year, driven by video streaming, cloud computing, and AI training data transfers. A single viral live event can spike regional traffic by tens of Tbps.
What happens if a submarine cable carrying Tbps of data gets cut?
Internet traffic automatically reroutes through other cables and paths via BGP routing protocols, usually within seconds. Speed may degrade in the affected region but rarely drops entirely. Cable cuts happen more often than people think — about 100 per year globally, mostly from ship anchors and fishing trawlers.
How do submarine cables achieve hundreds of Tbps?
Dense wavelength-division multiplexing (DWDM) sends dozens of different light colors (wavelengths) through a single fiber simultaneously, each carrying its own data stream. A modern cable contains multiple fiber pairs, each carrying 100+ wavelengths, with each wavelength modulated at 400 Gbps or more.
Could a single Tbps connection download all of Netflix?
Netflix's library is estimated at around 30–40 petabytes. At 1 Tbps, downloading the entire catalog would take roughly 70–90 hours. At 100 Tbps (a realistic submarine cable capacity), you could theoretically grab all of Netflix in under an hour.
What is the fastest data transfer ever achieved in a lab?
Researchers at Japan's NICT achieved 22.9 Pbps (22,900 Tbps) through a single multicore fiber in 2024. That is enough to transfer the entire Library of Congress in a fraction of a second. These lab records typically reach commercial deployment 5–10 years later.
