Umahluko phakathi kweSimplex Duplex kunye neHalf Duplex

Ekuhanjisweni konxibelelwano lwe-optical, sinokuva rhoqo i-simplex, i-duplex kunye ne-half-duplex, kunye ne-single-core kunye ne-double-core;Ifayibha enye kunye nefayibha ezimbini, ke ezi zintathu zihlobene kwaye yintoni umahluko?

Okokuqala, makhe sithethe nge-single-core kunye ne-double-core;I-fiber enye kunye ne-dual-fiber, kwimodyuli ye-optical, zombini ziyafana, kodwa igama lihlukile, imodyuli ye-optical single-core kunye ne-fiber-fiber optical module ziyi-fiber enye ye-bidirectional zombini iimodyuli ze-BIDI Optical,iimodyuli ezimbini-core opticalkunye neemodyuli ze-fiber-optical optical modyuli zimbini-fiber bidirectional optical modules.

Yintoni iSimplex?

I-Simplex ithetha ukuba ukuhanjiswa kwendlela enye kuphela kuxhaswa kwi-data data.Kwii-aplikeshini eziphathekayo, kukho abashicileli, izikhululo zerediyo, iimonitha, njl. njl. Yamkela kuphela imiqondiso okanye imiyalelo, musa ukuthumela iimpawu.

Yintoni i-half duplex?

I-half-duplex ithetha ukuba ukuhanjiswa kwedatha kuxhasa ukuhanjiswa kwe-bidirectional, kodwa ayikwazi ukwenza ukuhanjiswa kwe-bidirectional ngexesha elifanayo.Kwangaxeshanye, isiphelo esinye sinokuthumela okanye sifumane kuphela.

Yintoni i-duplex?

I-Duplex ithetha ukuba idatha ihanjiswa kumacala amabini ngexesha elinye, okuyindibaniselwano yeendlela ezimbini zonxibelelwano ezilula, ezifuna isixhobo sokuthumela kunye nesixhobo esifumanayo sibe nesakhono sokwamkela nokuthumela ngokuzimeleyo ngaxeshanye.

Kwimodyuli ye-optical, i-half-duplex yi-BIDI imodyuli ye-optical, enokudlulisa kwaye ifumane ngeshaneli enye, kodwa inokudlulisa idatha kwicala elinye ngexesha, kwaye inokufumana kuphela idatha emva kokuthumela idatha.

I-duplex yimodyuli eqhelekileyo yefiber ephindwe kabini.Kukho amajelo amabini okuhanjiswa, kwaye idatha ingathunyelwa kwaye ifunyenwe ngexesha elifanayo.
