SFP transceivers are designed to support SONET, gigabit Ethernet, Fibre Channel, and other communications standards. Due to its smaller size, SFP obsolesces the formerly ubiquitous gigabit interface converter (GBIC); the SFP is sometimes referred to as a Mini-GBIC. In fact, no device with this name has ever been defined in the MSAs.

Although it is not mentioned in any official specification document the maximum data rate of the original SFP standard is 6Gbit/s
The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. The form factor and electrical interface are specified by a multi-source agreement (MSA) under the auspices of the SFF Committee. It interfaces a network device motherboard (for a switch,router, media converter or similar device) to afiber optic or copper networking cable. It is a popular industry format jointly developed and supported by many network component vendors. SFP transceivers are designed to support SONET, gigabit Ethernet, Fibre Channel, and other communications.

Intel Optane Memory has a mission:
Make hard drives faster than SSDs
Intel’s Optane Memory could be the most revolutionary letdown in storage history. Announced Monday morning, these first consumer Optane-based devices will be available April 24 in two M.2 trims: A 16GB model for $44 and a 32GB Optane Memory device for $77. Both are rated for crazy-fast read speeds of 1.2GBps and writes of 280MBps.
If you’re wondering how you can install Windows 10 on one of these, you can’t. The first two Optane Memory devices instead are meant to be used primarily as cache drives for a traditional hard drive, using a technique similar to the Smart Response Technology Intel introduced in 2011.
Why this matters: Optane Memory is a far cry from what we expected after Intel and Micron announced 3D XPoint in 2015. The non-volatile memory was hyped as the next fast thing, promising “1,000X” the performance of today’s NAND-based SSDs with far higher density and lower cost than DRAM. 3D XPoint had me wondering just how it would reshape the PC down the road, when a computer could potentially have a simple 4TB of 3D XPoint memory doing it all, rather than 16GB of RAM and a hard drive. Apparently we have to be patient.
Why you shouldn’t dismiss Optane
Anyone who expected the first Optane drives to re-balance the galaxy is likely to be very disappointed with Intel Optane Memory. These first two Optane drives aren’t intended for enthusiasts, nor anyone with a beefy computer. They’re aimed at the huddled masses who still use traditional, spinning-platter hard drives. There are a lot of them: IDC data cited by Intel shows roughly 80 percent of desktop PCs in the world still use hard drives. (Full disclosure: IDC and PCWorld are separate business units of International Data Group.) They’ll continue to do so, too, because the cost per megabyte is so affordable.
Add Optane Memory to a current PC such as my own, and drive performance would be exponentially better, Intel claims.
