Tbps

(TeraBits Per Second, TeraBytes Per Second) One trillion bits or bytes per second. Tbps is a measurement that prior to the 21st century was unthinkable. As 40 and 100 Gbps Ethernet become the norm for high-speed backbones, terabit-per-second ratings will become common in the future. See space/time, Gbps and Mbps.


The Holy Optochip
In 2012, IBM introduced an optical chipset that transfers data at 1 Tbps. Designed for short-range transmission (less than 500 feet) in a multimode fiber array, the CMOS chip has 48 holes (top) that allow access to the 24 photodiode receivers and 24 VCSEL transmitters as seen from the back (bottom).

Just last August, Globe launched the Southeast Asia-United States (SEA-US) cable system that has a design capacity of 20 Tbps capacity and directly links Asia to the US.
Out of the current bandwidth capacity of more than 16 Tbps, Globe's "lit-up" capacity is less than three Tbps as the rest of the bandwidth remain unused due to insufficient last mile infrastructure.
Therefore, considering optical signals in excess of 1 Tbps multiplexed from ten wavelengths, for example, the new method can process them using just one-tenth of the power or less compared to previous technologies that required a separate circuit to convert each wavelength into an electrical signal and back.
This full-scale multi-terabit transmission, which took place on the Orange optical fiber infrastructure of its operational network during a trial that lasted several weeks, is a world record, not only in terms of global data capacity transported (38.4 Tbps), but also in the transmission distance (762 km / 472 miles).
SDS TBPs in comparison to all TBPs show highest sorption tendency as after SDS pretreatment TBPs surface is loaded with the negatively charged groups that provide more attachment sites for Cu (II) ions.
This new optical link, with capacity four times higher than the maximum bandwidth currently available and using 44 wavelengths, can transmit up to 17.6 Terabits per second (Tbps) of traffic in total.
Mr Ruggeri Telecom explained that the system has a design capacity of 5.12 Tbps and supported by the new 40 Gbps wavelength division multiplexing (WDM) technology that would accommodate futures ultra-broadband networks.
In Middle East and Africa, average Internet traffic will reach 5 Tbps in 2015, the equivalent of 4,500,000 people streaming Internet HD video simultaneously.
It will cross the Mediterranean Sea, connecting Darna in eastern Libya with Chania, Greece and will have an initial capacity of 7 x 10 Gbps and a maximum theoretical capacity of 1.2 Tbps.
At CERN, the current non-blocking capacity of the core is in the region of 4.2 Terabits per second (Tbps), and has doubled in the last two years.
By using the latest 40 gigabits per second (Gbps) per wavelength technology, the cable is expected to have a capacity of up to 5.12 terabits per second (Tbps), and will be further upgradeable to beyond 12 Tbps with future 100 Gbps per wavelength technology.
