Kule mihla, ngokufika kwetekhnoloji ye-5G, uninzi lwezicelo zetekhnoloji yenethiwekhi kubomi bethu bemihla ngemihla ziye zatshintsha kakhulu. Ke, izicelo zeemodyuli ze-optical ezihlala zisetyenziswa kwishishini zitshintshile ukusuka kumgama omfutshane ukuya kwizicelo ezimfutshane kunye nophuhliso lwamanethiwekhi. Umgama omde uye wakhula ngokuthe ngcembe.

1. Ingcamango yeiimodyuli ze-optical ezide:

Umgama wokudluliselwa ngenye yezinto ezibalulekileyo zeemodyuli ze-optical. Iimodyuli ze-Optical zihlukaniswe kwiimodyuli ze-optical ezikude, iimodyuli ze-optical ezikude, kunye neemodyuli ze-optical ezikude. Imodyuli ye-optical ende ubude yimodyuli ye-optical kunye nomgama wokudluliselwa ongaphezu kwe-30km. Ekusetyenzisweni kwangempela kwemodyuli ye-optical ekude, umgama ophezulu wokuhanjiswa kwemodyuli awukwazi ukufikelela kwiimeko ezininzi. Oku kungenxa yokuba isignali ye-optical iya kubonakala kwinkqubo yokuhanjiswa kwefiber optical. Ukuze ucombulule le ngxaki, imodyuli ye-optical ekude ithatha i-wavelength enye kuphela kwaye isebenzisa i-laser ye-DFB njengomthombo wokukhanya, ngaloo ndlela inqanda ingxaki yokusabalalisa.

2. Iindidi zeemodyuli zomgama omde wamehlo:

Kukho iimodyuli ze-optical ezikude ezikude phakathi kweemodyuli ze-SFP optical, i-SFP + iimodyuli ze-optical, iimodyuli ze-XFP optical, i-40G iimodyuli ze-optical, i-40G iimodyuli ze-optical, kunye ne-100G iimodyuli ze-optical. Phakathi kwabo, umgama omde we-SFP + imodyuli ye-optical isebenzisa i-laser ye-EML kunye ne-photodetector components. Ukuphuculwa okuhlukeneyo kunciphise ukusetyenziswa kwamandla kwimodyuli ye-optical kunye nokuphucula ukuchaneka; Umgama omde we-40G imodyuli ye-optical usebenzisa umqhubi kunye neyunithi yokumodareyitha kwikhonkco yokudlulisa, kwaye ikhonkco elifumanayo lisebenzisa i-amplifier optical kunye neyunithi yokuguqula i-photoelectric, engakwazi ukufikelela kumgama ogqithisiweyo we-80km, ode kakhulu kune-optical. umgama wothumelo lomgangatho okhoyo we-40G wemodyuli ye-optical pluggable .

3.ukusetyenziswa kweemodyuli zomgama omde zamehlo:

a.Izibuko zokutshintsha kwamashishini
b.Izibuko leseva
c.Izibuko lekhadi lothungelwano
d.Ummandla wokubeka iliso kwezokhuseleko
I-e.Telecom field, kubandakanywa iziko lokulawula idatha, igumbi lekhompyutha, njl.
f.Ethernet (Ethernet), iFiber Channel (FC), i-Synchronous Digital Hierarchy (SDH), i-Synchronous Optical Network (SONET) kunye nezinye iinkalo.

4. Izilumkiso zokusebenzisa iimodyuli zokujonga umgama omde:

Iimodyuli zomgama omde we-optical zineemfuno eziqinileyo kuluhlu lwamandla okufumana amandla. Ukuba amandla okukhanya adlula uluhlu olufumanayo lwe-sensitivity, imodyuli ye-optical iya kungasebenzi kakuhle. Ukusetyenziswa kunye nezilumkiso zezi zilandelayo:
a. Musa ukudibanisa i-jumper ngokukhawuleza emva kokufaka imodyuli ye-optical engaphezulu kumgama omde kwisixhobo, sebenzisa kuqala umgca womyalelo bonisa ukuxilongwa kwe-transceiver.

I-interface ifunda amandla okukhanya afunyenweyo kwimodyuli ye-optical ukujonga ukuba amandla okukhanya angaphakathi koluhlu oluqhelekileyo. Amandla okukhanya afunyenweyo ayiloxabiso elingaqhelekanga njenge +1dB. Xa i-fiber optical ingaxhunywanga, isoftware idla ngokubonisa ukuba amandla okukhanya afunyenweyo anokuba yi -40dB okanye ixabiso eliphantsi.

b Ukuba kunokwenzeka, ungasebenzisa imitha yamandla okukhanya ukuze uvavanye ukuba amandla afunyenweyo kunye akhutshwayo angaphakathi kwinqanaba eliqhelekileyo lokufumana ngaphambi kokudibanisa i-fiber optical kwimodyuli ye-optical echazwe ngasentla.

c. Ngaphantsi kweemeko kufuneka i-fiber optical ifakwe ngokuthe ngqo ukuvavanya iimodyuli ze-optical ezichazwe ngasentla. Ukuba kuyimfuneko, i-optical attenuator kufuneka iqhagamshelwe ukwenza amandla optical afunyenweyo ngaphakathi kwendawo yokufumana ngaphambi kokuba uvavanyo lwe-loopback lwenziwe.

f. Xa usebenzisa imodyuli ye-optical ekude, amandla afunyenweyo kufuneka abe nomda othile. Awona mandla afunyenweyo agcinelwe ngaphezulu kwe-3dB xa kuthelekiswa nokufumana ubuntununtunu. Ukuba ayihambelani neemfuno, kufuneka kongezwe i-attenuator.

g. Iimodyuli zomgama omde we-optical zingasetyenziswa kwi-10km yokuhanjiswa kwezicelo ngaphandle kokunciphisa. Ngokuqhelekileyo, iimodyuli ezingaphezulu kwe-40km ziya kuba ne-attenuation kwaye azikwazi ukudibanisa ngokuthe ngqo, ngaphandle koko kulula ukutshisa i-ROSA.
