Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver , such as for a fiber-optic cable or a copper cable. [ 1 ]
Intel XFP Transceiver (MultiMode Fiber Optics) 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.
QSFP28 modules use the CAUI-4 electrical interface. SFP-DD or Small Form-factor Pluggable – Double Density modules use the 100GAUI-2 electrical interface. Cisco's CPAK optical module uses the four lane CEI-28G-VSR electrical interface. [127] [128] There are also CXP and HD module standards. [129] CXP modules use the CAUI-10 electrical interface.
The CFP transceiver is specified by a multi-source agreement (MSA) among competing manufacturers. [2] The CFP was designed after the small form-factor pluggable transceiver (SFP) interface, but is significantly larger to support 100 Gbit/s.
SFP-DD is defined by the SFP-DD MSA and enables breakout to two SFP ports. Two rows of electrical contacts enable doubling the throughput of SFP modules in a similar fashion as QSFP-DD. The quad small form-factor pluggable (QSFP) module began being used for switch inter-connectivity and was later adopted for use in 4-lane implementations of Gen ...
Like many others who found themselves working remotely, Linette Miller, 59, noticed that she had become sedentary. “It suddenly dawned on me how little activity I get every day,” Miller, from ...
Of these activities, SFP requires only the first two, i.e., the identification of logical data files and transactions. Activities 4) and 5) are the most time consuming, since they require that every data file and transaction is examined in detail: skipping these phases makes the SFP method both quicker and easier to apply than IFPUG FPA.
