In 2006, SFP+ specification brought speeds up to 10 Gbit/s and the later SFP28 iteration, introduced in 2014, [5] is designed for speeds of 25 Gbit/s. [6] A slightly larger sibling is the four-lane Quad Small Form-factor Pluggable (QSFP). The additional lanes allow for speeds 4 times their corresponding SFP.
The C form-factor pluggable (CFP) is an MSA among competing manufacturers for a common form-factor for the transmission of high-speed digital signals. The letter "C" in the name stands for the Latin letter C used to express the number 100 ( centum ), since the standard was primarily developed for 100 Gigabit Ethernet systems.
Direct-Attach Copper (DAC) is a type of standard cabling used in Small Form-factor Pluggable (SFP) Ethernet, initially defined with SFP+ Direct-Attach Copper (10GSFP+Cu), which provides 10 Gigabit Ethernet over either an active or passive twinax cable assembly and connects directly into an SFP+ housing. An active twinax cable has active ...
1000BASE-SX GBIC. Gigabit interface converter (GBIC) is a standard for transceivers.First defined in 1995, it was used with Gigabit Ethernet and Fibre Channel.By standardizing on a hot swappable electrical interface, a single gigabit port can support a wide range of physical media, from copper to long-wave single-mode optical fiber, at lengths of hundreds of kilometers.
The XFP (10 gigabit small form-factor pluggable) is a standard for transceivers for high-speed computer network and telecommunication links that use optical fiber. It was defined by an industry group in 2002, along with its interface to other electrical components, which is called XFI .
The C form-factor pluggable (CFP, 100G form factor pluggable, where C is Latin: centum "hundred") [1] is a multi-source agreement to produce a common form-factor for the transmission of high-speed digital signals.
This smaller form factor is similar to that used in an HDD by Rodime in 1983, which was the same size as the "half height" 3½" FDD, i.e., 1.63 inches high. Today, the 1-inch high ("1/3 height," "slimline," or "low-profile") version of this form factor is the most popular form used in most desktops.
The SPARCstation 20 has dual 50 MHz MBus ports that allow it to use faster CPUs than the SPARCstation 10. With two dual-CPU modules and updated firmware, the SPARCstation 20 supports a maximum of four CPUs. The fastest CPU produced for the SPARCstation 20 is the 200 MHz Ross hyperSPARC. The PROM in the SPARCstation 20 determines CPU ...
