		A gigabit per second (Gbps or Gbit/s) is a unit of data transmission equal to 1,000 megabits per second or 1,000,000 kilobits per second or 1,000,000,000 bits per second.
		In ultra high-speed optical transmission beyond 10 Gbit/s, however, as it was difficult to modulate and demodulate optical multi-level signals, more than 8 levels of optical multi-level modulation had not been achieved.
		On the other hand, while a high-speed practical modulation speed of 40 Gbit/s has already been achieved for optical signals, modulation speed also cannot be increased as the frequency bandwidth of optical signals would also increase and interfere with optical signals at adjacent wavelengths.

	Inhibitory effect of Gamibojungikgitang extract on mast cell-mediated allergic reaction in murine model.
		Thus, it is possible to hypothesize that GBIT extract might act on the lipid bilayer membrane affecting the prevention of the perturbation induced by compound 48/80 and regulate the degranulation of the mast cells in mouse skin by stabilizing membrane fluidity.
		The effects of GBIT extract on mast cell cytokine secretion in vivo and the relative importance of mast cell as a source of chemotactic factor IL-6 during inflammatory and immune response are important areas for future studies.
		GBIT is a complex prescription that is known to enhance spleen and stomach-qi on the basis of Oriental medicine theory (1).

	The 40 Gbit/s optical network: why, how and when?The 40 Gbit/s optical network: why, how and when? (November ...
		The big benefits of 40 Gbit/s technology, according to its advocates, are a 50% smaller footprint than equivalent 10 Gbit/s-based systems, 20-40% lower power requirements, and easier management (because there are 75% fewer wavelengths).
		Moving from 10 to 40 Gbit/s increases the chromatic and polarization-mode dispersion 16-fold and 2- to 4-fold, respectively, while 40 Gbit/components are not yet qualified in volumes.
		They certainly want their new equipment to be 40 Gbit/s compatible, and if they have it, the chances are that they will use it.

	Will iSCSI over 10 Gbit copper Ethernet radically alter the SAN market?
		Application servers running iSCSI over 1 Gbit Ethernet have historically not been able to match FC's heady numbers because there is no difference between the speed of the application server ports and those on the target storage array.
		Ten Gbit copper Ethernet is a fraction of the cost of optical 10 Gbit Ethernet.
		IDC predicts approximately 200,000 10 Gbit Ethernet interfaces will be installed by the end of 2006.

	Building Blocks Ready for Gbit Ethernet Military Networks \| COTS Journal
		Both 1 and 10 Gbit flavors of Ethernet are undergoing an evolutionary pattern reminiscent of that taken by Fast Ethernet.
		Furthermore, with 10 Gbit Ethernet solutions around the corner, evolutionary changes in backplane standards, end node architectures and evolving CPUs and NICs are making it possible for both 1/10 Gbit Ethernet to be the cost-effective switched fabric solution of choice for low, medium and even higher-speed network applications.
		With the proper network topology and configuration of commodity switch chip technology, it is now possible to achieve wirespeed performance of Gbit Ethernet as a switch fabric with drop-less operation, relative low latencies and satisfactorily deterministic behavior.

	Inphi proposes 40 Gbit/s standard (May 2002) - News & Analysis - fibers.org
		It is designed to enable long-haul equipment suppliers to build 43-50 Gbit/s linecards and allow module manufacturers to develop cost-competitive solutions for short-reach and metro applications at 40 Gbit/s.
		A 40 Gbit/s transponder multi-source agreement was announced at ECOC last October, and an SFI-5 interface standard was presented to the OIF late last year.
		The proposed architecture uses CMOS to implement functions up to 10 Gbit/s, while InP is used for the parts that operate at 40-50 Gbit/s and interface with the physical layer functions (see figure).

		But then again, Ethernet previously jumped by a factor of 10, from 1 Gbit/s to 10 Gbit/s, so another factor of 1 to 100-Gbit/s standard seems logical.
		So far, any Ethernet needs beyond 10 Gbit/s have been handled with link aggregation (often referred to as LAG), the IEEE method for combining multiple lines into a single virtual link.
		This makes pipes of up to 80 Gbit/s possible, but some question how well LAG works beyond that point.

		In addition to the previously used STM-64/OC-192 (9.95328 Gbit/s) standards, we are also seeing use of 10.709225 Gbit/s (OTU-2), which includes FEC coding, as well as 3.125 Gbit/s x 4 and 10.3125 Gbit/s in 10 Gbit Ethernet.
		As these new standards are settled upon, there is an urgent need to be able to support evaluation of devices and circuits at these higher bit rates.

	Gbit Ethernet vs. Myrinet--again (Site not responding. Last check: 2007-10-17)
		Gbit Ethernet does not perform as well as Myrinet latency-wise and possibly bandwidth-wise.
		On http://www.scl.ameslab.gov/Projects/ClusterCookbook/icperf.html, it looks like Gbit Ethernet is comparable in latency and throughput to Myrinet, though, they are probably not using any of the active protocols over Myrinet which have extremely low latency.
		Further, after pricing 3Com Gbit NICs and a 3Com Gbit hubs and switches, I believe that Gbit Ethernet is cheaper per node than Myrinet now, mainly because the 3Com NICs are 1/2-1/3 the price of the Myrinet NICs.

	Inphi achieves 80 Gbit/s data rate with indium phosphide demultiplexers (January 2002) - News - Compound Semiconductor
		Inphi's 80 Gbit/s achievement in indium phosphide exceeds recently published results in silicon germanium, which reached half-rate speeds of only 56 Gbit/s.
		At a reduced data rate of 40 Gbit/s, for example, Inphi's half-rate demultiplexer dissipates only 400 milliwatts of power, which is approximately one third the power as SiGe half-rate circuits operating at the same speed.
		The Inphi 80 Gbit/s circuits are based on a half-rate architecture, which is equivalent in terms of clock rate to a full-rate circuit running at 40 Gbit/s.

	DWDM platform gets set for 40 Gbit/s delivery (February 2006) - News & Analysis - fibers.org
		As carriers' interest in 40 Gbit/s technologies continues to ramp up, Huawei Technologies is getting in on the action with the addition of 40 Gbit/s DWDM capability to its OptiX BWS 1600G and 1600A DWDM transmission platforms.
		The hybrid system enables carriers to mix and match 10 and 40 Gbit/s capability in one box, extending their primary equipment investment and enabling a smooth evolution from 10 to 40 Gbit/s data rates.
		For starters, a special modulation format improves the dispersion and PMD tolerance at 40 Gbit/s and, used in conjunction with super-forward-error-correction (SFEC) technology, enables a high receiver sensitivity with optical signal-to-noise ratios on a par with those seen at 10 Gbit/s.

		4 Gbit NAND Flash was introduced by Samsung for the first time back in 2003 as the fifth generation of the technology.
		While the company already offers 8 Gbit devices, the 70 nm units currently integrate the smallest memory cell size of NAND Flash in the industry (0.025 2).
		The 4 Gbit memories are able to write data at 16 MByte per second, which is about twice the speed of a 90 nm 2Gbit device and enough to allow real-time data storage of high-definition (HD) video images.

	40 Gbit/s Testing - EXFO
		In addition to greater speeds, this new technology means a possible shift toward different infrastructures to compensate for the various challenges not found in slower networks like 10 Gbit/s.
		The spectral response of a 40 Gbit/s transmitter is far larger than that of 10 Gbit/s.
		As 40 Gbit/s networks introduce lower dispersion tolerances, more devices will need to be installed to compensate for this.

		The trial was conducted on MCI's 1200 km ULH DWDM optical network, between Sacremento, CA, and Salt Lake City, UT. This route was chosen because it contains a mix of fiber, including dispersion-shifted fiber, long-span fiber, and single-mode fiber, illustrating MCI's claims of real-world scalability of its network.
		The 40 Gbit/s system was commissioned in less than an hour, and then performed error-free on the same optical fibers already carrying 10 Gbit/s transmission throughout the trial.
		And Mintera president and CEO, Terry Unter, commented that the 40 Gbit/s system "will allow service providers such as MCI to gain a significant bandwidth boost from installed infrastructure, thus delaying capital investments in equipping new dark fibers and, at the same time, permitting the deployment of new, bandwidth-intensive services."
