Lebitso le felletseng la module oa optical ketransceiver ea mahlo, e leng sesebelisoa sa bohlokoa tsamaisong ea puisano ea fiber optical.E na le boikarabello ba ho fetola lets'oao la optical le amoheloang hore e be lets'oao la motlakase, kapa ho fetolela lets'oao la motlakase le kenang hore e be lets'oao le tsitsitseng la optical ka sekhahla se ts'oanang.
Theoptical module e entsoe ka lisebelisoa tsa optoelectronic, li-circuits tse sebetsang le li-interfaces tsa optical.Lisebelisoa tsa optoelectronic li kenyelletsa likarolo tse peli: ho fetisa (TOSA) le ho amohela (ROSA).
Likarolo tsa bohlokoa tsa tekheniki tsa module ea optical li kenyelletsa matla a optical a fetisitsoeng, karo-karolelano ea ho timela, ho amohela kutlo, le matla a optical a tletseng.
1. Ka karolelano matla a fetisitsoeng a optical a bolela palo ea lipalo tsa matla a optical ha logic ea pontšo e le 1 le matla a optical ha e le 0.
2. Karo-karolelano ea ho timela e bolela karo-karolelano ea matla a optical a fetisitsoeng a likhoutu tsohle tsa "1" ho matla a tloaelehileng a fetisoang a likhoutu tsohle tsa "0".E tla ama kutloisiso ea ho amohela.Karolelano ea ho fela e lokela ho laoloa ka har'a sebaka se lekaneng.Karolelano e kholo ea ho timela e thusa ho fokotsa kotlo ea Matla, empa e kholo haholo e tla eketsa jitter e amanang le mohlala ea laser.
3. Ho amohela kutloisiso ho bolela moeli o fokolang oo sebaka se amohelang se ka amohelang lets'oao.Ha matla a lets'oao a pheletso e amohelang a le ka tlase ho kutloisiso e tloaelehileng ea ho amohela, pheletso e amohelang e ke ke ea fumana data efe kapa efe.
4. Matla a matla a optical a tletseng matla a matla a matla a matla a optical a bolela matla a mangata a bonahalang a optical qetellong ea ho amohela mochine oa optical, ka kakaretso -3dBm.Ha matla a optical a amohetseng a le kholo ho feta matla a mahlo a tletseng, ho tla hlahisoa liphoso tse nyane.Ka hona, haeba mochine oa optical o nang le matla a phahameng a ho fetisa o lekoa ntle le ho fokotseha le loopback, liphoso tse nyenyane li tla etsahala.
