Nyob rau hauv tus txheej txheem ntawm kev siv industrial Ethernet keyboards, tib neeg feem ntau tuaj rau hauv kev sib cuag nrog SFP thiab Combo ports. Yog li, ob qhov chaw nres nkoj no yog dab tsi hauv kev lag luam hloov pauv? Dab tsi yog qhov txawv ntawm SFP chaw nres nkoj ntawm Industrial Ethernet hloov thiab Combo chaw nres nkoj? Tom ntej no, cia peb ua rawsJHA TECHto taub!

SFP chaw nres nkojyog ib tug subset ntawm Gigabit Ethernet chaw nres nkoj. Thaum SFP chaw nres nkoj siv optical fiber Gigabit txuas, nws yog Gigabit Ethernet chaw nres nkoj ; Hauv kev hloov Ethernet, txheej txheej txuas siv ib txoj cai rau ob qho tib si hluav taws xob thiab cov chaw nres nkoj kho qhov muag. Qhov txawv tsuas yog lub cev txheej, uas yog, qhov nruab nrab yog siv dab tsi; SFP yog ib qho kev piav qhia ntawm lub cev txheej.

Combo feem ntau yog hais txog photoelectric multiplexing. Qhov ntawd yog hais tias, tsuas yog ib qho ntawm ob qhov chaw nres nkoj (ib lub teeb thiab ib qho hluav taws xob raug suav tias yog ib txheej ntawm Combo) tuaj yeem siv tib lub sijhawm, piv txwv li, qhov chaw nres nkoj hluav taws xob tsis tuaj yeem siv thaum lub teeb siv. Lub SFP module yog ntsaws rau hauv qhov chaw nres nkoj kho qhov muag ntawm kev lag luam Ethernet hloov. Tom qab ntsaws rau hauv, nws tuaj yeem sib txuas lus los ntawm cov khoom siv kho qhov muag thiab qhov chaw nres nkoj qhov twg SFP module tseem txuas rau ntawm qhov kawg ntawm qhov kawg, tsis tas yuav tsum tau hloov kho qhov muag fiber ntau transceiver.

Muaj Ethernet keyboards yooj yim siv, tsuas yog ntsaws rau hauv cov chaw nres nkoj sib xws, yog li nws yuav tsum nkag siab tias qhov chaw nres nkoj SFP thiab Combo chaw nres nkoj yog dab tsi.
