Ezokuxhumana zanamuhla kanye nokudluliswa kwedatha,izamukeli ze-opticalzidlala indima ebalulekile ekuqinisekiseni ukudluliswa kolwazi okungenazihibe nokuphumelelayo. Lawa madivayisi ayinkimbinkimbi aklanyelwe ukubamba amasignali okukhanya futhi awaguqule abe amasignali kagesi, okwenza abe yizingxenye ezibalulekile ezinhlelweni zokusebenza kusukela kwezokuxhumana kuya ezikhungweni zedatha.
Enye yentuthuko yakamuva kubuchwepheshe bokwamukela ukukhanya ukuhlanganiswa kwama-photo-detector asebenza kahle kakhulu asebenza ebangeni lamaza obubanzi obungu-1200 kuya ku-1620 nm. Lokhu kusebenza okuthuthukisiwe kuvumela ukwamukelwa kwezimpawu eziningi ezibonakalayo, okwenza umamukeli akwazi ukushintshashintsha futhi azivumelanise nezimo ezindaweni ezahlukene zenethiwekhi.
Ngaphezu kokumbozwa kobubanzi be-wavelength, i-optical receiver inomklamo onomsindo ophansi oyenza isebenze ebangeni lokufaka eliqala ku--25dBm kuya ku-0dBm. Lokhu kuzwela okumangalisayo kuqinisekisa ukuthi ngisho nezimpawu zokukhanya ezibuthakathaka zibanjwa futhi ziguqulwe kahle, okuvumela ukudluliswa kwedatha okuthembekile nokuseqophelweni eliphezulu.
Ngaphezu kwalokho, izinsiza zamandla ezimbili ezakhelwe ngaphakathi zengeza ukuthembeka okwengeziwe kanye nokuqina kwesamukeli se-optical. Ngokushintsha okuzenzakalelayo kanye nokusekelwa kwe-hot-swap, isamukeli singazivumelanisa kalula nezinguquko ekunikezweni kwamandla, sinciphise isikhathi sokungasebenzi futhi siqinisekise ukusebenza okuqhubekayo.
Ukuhlanganiswa kwesixhumi esibonakalayo se-RJ45 esijwayelekile kuthuthukisa kakhulu ukuguquguquka nokufinyeleleka kwesamukeli se-optical. Lesi sixhumi asilula nje kuphela ukuxhumana, kodwa futhi sisekela ukuphathwa kwenethiwekhi ekude ye-SNMP kanye ne-Web, okungahlanganiswa kalula nengqalasizinda yenethiwekhi ekhona futhi kufeze ukuqapha nokulawula okukude.
Ukuhlanganiswa kwalezi zici ezithuthukisiwe kwenza ama-optical receiver abe amathuluzi anamandla futhi abalulekile kwezokuxhumana zesimanje kanye nezinhlelo zokudlulisa idatha. Amandla ayo okubamba izinhlobo eziningi zezimpawu zokukhanya ezinozwela oluphezulu, kanye nomklamo wayo oqinile kanye namakhono okuphatha kude, kuyenza ifaneleke kakhulu ezindaweni zenethiwekhi ezidinga kakhulu.
Kungakhathaliseki ukuthi kusetshenziswe kumanethiwekhi okuxhumana, izikhungo zedatha noma izinhlelo zokusebenza zezimboni,izamukeli ze-opticalkuyibufakazi bokuqhubeka kokusungula izinto ezintsha kanye nokuthuthuka kobuchwepheshe be-optical. Ikhono layo lokuzivumelanisa nezidingo zenethiwekhi ezishintshayo nokuletha ukusebenza okuthembekile ligcizelela ukubaluleka kwayo ekwakheni ikusasa lokuxhumana kanye nokudluliswa kwedatha.
Ngamafuphi, ukuhlanganiswa kwezitholi zezithombe ezisebenza kahle kakhulu, ukwakheka komsindo ophansi, izinsiza zamandla ezimbili, kanye namakhono okuphatha kude kuletha ukusebenza kwesamukeli se-optical kanye nokuguquguquka ezingeni eliphezulu. Njengoba isidingo sokudluliselwa kwedatha okusheshayo, okuthembekile, nokusebenza kahle siqhubeka nokukhula, abamukeli be-optical bakulungele ukubhekana nezinselele zezindawo zenethiwekhi zesikhathi esizayo.
