Sforzando means a strong, sudden accent and is abbreviated as sf, sfz or fz. The notation sfzp (or sfp) means a sforzando followed immediately by piano.
[Subito piano (abbreviated sub. p or sp) ("suddenly soft") indicates that the dynamics quickly, almost abruptly, lower the volume to approximately the p range. It is often purposefully used to subvert the listener's expectation and will signify an intimate expression.
fp - fortepiano - loud then immediately soft. sfz - sforzando - sudden accent. sf - sforzato - sudden accent. fz - forzando, forzato - sudden accent. sfzp, sfp, fzp - sudden accent followed immediately by piano.
Sforzando: Forced, accented. Abbreviated sf or sfz. As far as "sfp" goes, it means play it forte but suddenly piano.
An SFP module is used to interconnect fiber cables to network switches and other communication devices, such as industrial Ethernet switches and media converters.
Cable Type
SFP module can work over optical fiber and copper. Based on the types of optical fibers, SFP transceiver can be divided into single mode SFP that works with single-mode fiber and multimode SFP that works with multimode fiber. Specfication. Multimode SFP. Single-mode SFP.
sforzando, sforzato (It.). 'Forcing', 'forced', i.e., accented. In the 19th century it was used to mark an accent within the prevailing dynamic, but it has now acquired the connotation of sudden loudness; it is abbreviated sf or sfz.
Really, sfz is an accent and fp is a rapid dynamic shift. So, if you had a crescendo that included a note with an sfz, then that note would be substantially louder than the one before it, but the note after it would be a little louder than the note before the sfz and the crescendo would keep going.
Usually, SFP ports use in Ethernet switches, routers, firewalls and NIC cards. SFP modules connect devices to fiber or copper cables like Cat5e. Other types of SFP optical transceivers like 3G video SFP and 12G video SFP. They are also used in HD cameras or monitoring systems.
The Singlemode SFP and Multi-mode SFP mean the SFP transceivers will work on different types of optical fibers; as in a Singlemode SFP will work with Singlemode fiber only, and a Multi-mode SFP will work with Multi-mode fiber only.
sfz means sforzando , a sudden accent. fp means fortepiano , loud then soft. sf means subito forte , play 'suddenly' (subito) loud (forte) rfz means rinforzando , play with gradual emphasis or broad accentuation until otherwise noted.
