Imodyuli ye-optical isetyenziselwa ukuguqula isignali yombane kwisixhobo (ngokuqhelekileyo ibhekisela kwisixhobo sokutshintsha okanye i-router) kwisignali ye-optical, kwaye emva koko idlulisele nge-fiber optical (iphunyezwe ekupheleni kokudlulisa imodyuli ye-optical), kwaye inokufumana i-fiber optical yangaphandle ngexesha elifanayo Isignali ye-optical edlulisiweyo iguqulwa ibe ngumqondiso wombane (oyenziwa ngokufumana isiphelo semodyuli ye-optical) kunye negalelo kwisixhobo. Ukungaphumeleli kokusebenza kwemodyuli ye-optical kwahlulwa kukungaphumeleli kwesiphelo sokudlulisa kunye nokungaphumeleli kokuphela kokufumana. Iingxaki eziqhelekileyo zigxininiswe kungcoliseko kunye nomonakalo we-port optical kunye nomonakalo we-ESD.

1. Ukungcola kunye nomonakalo kwi-port optical

Ngenxa yokungcola kunye nomonakalo we-interface optical, ukulahlekelwa kwekhonkco ye-optical kwanda, okubangelwa ukungaphumeleli kwekhonkco ye-optical. Izizathu zezi:
A. I-port optical yemodyuli ye-optical ibonakaliswe kwimeko engqongileyo, kwaye uthuli lungena kwaye lungcolise i-port optical;
B. Isiphelo sobuso bomdibaniso we-fiber optical esetyenzisiweyo uye wangcoliswa, kwaye i-port optical yemodyuli ye-optical ingcolisekile kabini;
C. Ubuso bokugqibela bekhonkco ye-optical kunye ne-pigtail isetyenziswe ngokungafanelekanga, ubuso bokugqibela buhlanjululwe, njl.;
D. Sebenzisa izihlanganisi zefiber optic ezisezantsi;

2. Umonakalo we-ESD
I-ESD sisishunqulelo se-ElectroStatic Discharge, okanye “i-electrostatic discharge”. Yinkqubo ekhawulezayo kakhulu enexesha lokunyuka elingaphantsi kwe-1ns (ibhiliyoni enye yesekhondi) okanye namakhulu e-ps (1ps=1,000 billionth of a second). I-electromagnetic pulse yeshumi le-Kv / m okanye ngaphezulu.Umbane osisigxina unokutsala uthuli, utshintshe i-impedance phakathi kwemigca, kwaye uchaphazele umsebenzi kunye nobomi bemveliso; ubushushu obuveliswa ngumbane okhawulezileyo okanye umsinga we-ESD ungonakalisa icandelo, kwaye usenokusebenza ngexesha elifutshane kodwa ubomi bayo buya kuchaphazeleka; inokulimaza i-insulation okanye i-conductor yecandelo, ibangela ukuba Icandelo alisebenzi (litshatyalaliswe ngokupheleleyo). I-ESD ayinakuphepheka. Ukongeza ekuphuculeni ukuxhathisa kwe-ESD kumacandelo e-elektroniki, kubalulekile ukuwasebenzisa ngokuchanekileyo.
