Njengesixhobo sokuguqula i-photoelectric, imodyuli ye-optical yeyona mveliso ixhaphakileyo kwinethiwekhi yonxibelelwano ye-optical. Phakathi kweempawu zeemodyuli ze-optical, umthamo wokuhambisa ungenye yezona zinto zibalulekileyo kunye neeparitha ezichaphazelekayo. Ukongezelela, umgama wokuhanjiswa kwemodyuli ye-optical enye iparameter engundoqo ayinakuhoywa. Kwiinkalo ezahlukeneyo kunye neekhonkco ze-optical network transmission network, iimpawu zeemodyuli ze-optical nazo zihluke.
Ngokomgama wokuhanjiswa kwemodyuli ye-optical, inokwahlulwa ibe ziindidi ezintathu: imodyuli ye-optical mfutshane, imodyuli yokukhanya ephakathi, kunye nemodyuli ye-optical ende. Imodyuli ye-optical ekude ibhekisela kwimodyuli ye-optical kunye nomgama wokudluliselwa kwe-30 km okanye ngaphezulu. Isidingo sokusasazwa komgama omde wedatha yenethiwekhi.
Ekusetyenzisweni kwangempela kwemodyuli ye-optical emide, umgama ophezulu wokuhanjiswa kwemodyuli awukwazi ukufezekiswa kwiimeko ezininzi. Oku kungenxa yokuba iqondo elithile lokusabalalisa lenzeka ngexesha lokuhanjiswa kwesignali ye-optical fiber optical. Ukusombulula le ngxaki, imodyuli ye-optical ekude yamkelwa. Inye kuphela i-wavelength elawulayo yi-laser yam ye-DFB njengomthombo wokukhanya, ngaloo ndlela inqanda ingxaki yokusasazwa.
Iimodyuli zexesha elide ze-optical zifumaneka kwiimodyuli ze-SFP ze-optical, i-SFP + iimodyuli ze-optical, iimodyuli ze-XFP ze-optical, i-25G iimodyuli ze-optical, i-40G iimodyuli ze-optical kunye ne-100G iimodyuli ze-optical. Phakathi kwabo, imodyuli ye-Optical SFP + ende ithatha i-EML laser component kunye necandelo le-photodetector, elinciphisa ukusetyenziswa kwamandla kwimodyuli ye-optical kunye nokuphucula ukuchaneka; umgama omde we-40G imodyuli ye-optical ithatha umqhubi kunye neyunithi yokumodareyitha kwikhonkco yokudlulisa, kwaye ifumana Ikhonkco isebenzisa i-amplifier optical kunye neyunithi yokuguqula i-photoelectric ukufezekisa umgama omkhulu wokuhanjiswa kwe-80 km.
Nangona kunjalo, umgama wokuhanjiswa kwemodyuli ye-optical awukho kangangoko kunokwenzeka, kwaye isisombululo esifanelekileyo kufuneka sithathwe xa kufanelekile. Usetyenziso lomgama omde lukwindawo zomncedisi wezibuko,tshintshaamazibuko, izibuko zamakhadi enethiwekhi, ukubekwa esweni kokhuseleko, unxibelelwano ngomnxeba, i-Ethernet, kunye nothungelwano lwe-optical synchronous.
