Pogwiritsa ntchito ma switch a Ethernet, anthu nthawi zambiri amakumana ndi madoko a SFP ndi Combo. Ndiye, madoko awiriwa pakusintha kwa mafakitale ndi chiyani? Kodi pali kusiyana kotani pakati pa doko la SFP la switch ya Industrial Ethernet ndi doko la Combo? Kenako, tiyeni titsatireChithunzi cha JHA TECHkuzimvetsa!

Chithunzi cha SFPndi kagawo kakang'ono ka Gigabit Ethernet port. Pamene doko la SFP limagwiritsa ntchito ulalo wa fiber Gigabit, ndi doko la Gigabit Ethernet; Pakusintha kwa Ethernet, ulalo wosanjikiza umagwiritsa ntchito protocol imodzi pamadoko amagetsi ndi owoneka. Kusiyana kokha ndiko kusanjika kwa thupi, ndiko kuti, chomwe chimagwiritsidwa ntchito; SFP ndi kufotokozera kwa gawo la thupi.

Combo nthawi zambiri amatanthauza photoelectric multiplexing. Izi zikutanthauza kuti, imodzi yokha mwa madoko awiri (kuwala kumodzi ndi magetsi amodzi amaonedwa ngati gulu la Combo) angagwiritsidwe ntchito nthawi imodzi, mwachitsanzo, doko lamagetsi silingagwiritsidwe ntchito pamene kuwala kukugwiritsidwa ntchito. Module ya SFP imalumikizidwa mu doko la kuwala kwa mafakitale a Ethernet switch. Pambuyo polumikiza, imatha kuyankhulana kudzera mu fiber optical ndi doko pomwe gawo la SFP limalowetsedwanso kumbali ina, popanda kufunikira kwa kutembenuka kwa fiber optical transceiver.

Zosintha za Industrial Ethernet ndizosavuta kugwiritsa ntchito, ingolowetsani madoko ofananirako, kotero ndikofunikira kumvetsetsa zomwe doko la SFP ndi doko la Combo ndi.
