Imojula ye-optical isetshenziswa kakhulu ukuguqula isignali kagesi kudivayisi (imvamisa ibhekisa ku-switch noma idivayisi ye-router) ibe isignali ye-optical, bese idlulisela nge-fiber optical (esetshenziswa ukuphela kokudlulisa kwe-optical module), futhi ingathola i-fiber optical yangaphandle ngesikhathi esifanayo Isignali ye-optical edlulisiwe iguqulwa ibe isignali kagesi (ebonakala ngokuthola ukuphela kwe-module optical) kanye nokufaka kudivayisi. Ukwehluleka kokusebenza kwemodyuli ye-optical kuhlukaniswe ukwehluleka kokuphela kokudlulisa kanye nokuhluleka kokuphela kokuthola. Izinkinga ezivame kakhulu zigxile ekungcoleni nasekulimaleni kwe-optical port kanye nomonakalo we-ESD.

1. Ukungcola kanye nokulimala kwe-optical port

Ngenxa yokungcola kanye nokulimala kwesixhumi esibonakalayo, ukulahleka kwesixhumanisi se-optical kuyanda, okuholela ekuhlulekeni kwesixhumanisi se-optical. Izizathu yilezi:
A. Imbobo yokubona yemojuli ye-optical ivezwa endaweni ezungezile, futhi uthuli lungena lungcolise imbobo yokubona;
B. Ubuso bokugcina besixhumi se-fiber optical esisetshenzisiwe bungcolisiwe, futhi imbobo yokubona yemojula yokubona ingcoliswe kabili;
C. Ubuso bokuphela kwesixhumi se-optical nge-pigtail sisetshenziswa ngendlela engafanele, ubuso bokuphela bukhishwe, njll;
D. Sebenzisa izixhumi ze-fiber optic ezingaphansi;

2. Ukulimala kwe-ESD
I-ESD isifinyezo se-ElectroStatic Discharge, noma “i-electrostatic discharge”. Kuyinqubo eshesha kakhulu enesikhathi sokukhuphuka esingaphansi kwama-1ns (ingxenye yesigidi sesekhondi) noma ngisho namakhulu ama-ps (1ps=1,000 billionth of a second). Ukushaya kwe-electromagnetic okunamandla kwe-Kv/m eziyishumi noma ngaphezulu.Ugesi omile ungaheha uthuli, uguqule i-impedance phakathi kwemigqa, futhi uthinte ukusebenza nempilo yomkhiqizo; ukushisa okukhiqizwa inkambu kagesi esheshayo noma i-current ye-ESD ingalimaza ingxenye, futhi isengasebenza ngesikhathi esifushane kodwa impilo yayo izothinteka; ingalimaza ngisho ne-insulation noma i-conductor yengxenye, okwenza Ingxenye ingasebenzi (ibhujiswe ngokuphelele). I-ESD ayinakugwenywa. Ngaphezu kokuthuthukisa ukumelana kwe-ESD kwezingxenye ze-elekthronikhi, kubalulekile ukuzisebenzisa ngendlela efanele.
