Namuhla, ngokufika kobuchwepheshe be-5G, ukusetshenziswa okuningi kobuchwepheshe benethiwekhi empilweni yethu yansuku zonke nakho kube nezinguquko ezinkulu.Ngakho-ke, ukusetshenziswa kwamamojula we-optical avame ukusetshenziswa embonini ashintshile ukusuka ebangeni elifushane ukuya kwezinhlelo zokusebenza zamabanga amafushane ngokuthuthukiswa kwamanethiwekhi.Ibanga elide liye lavuthwa kancane kancane.

1. Umqondo weamamojula optical amabanga amade:

Ibanga lokudlulisela lingenye yezinto ezibalulekile zamamojula optical.Amamojula we-Optical ahlukaniswe ngamamojula we-optical amabanga amafushane, amamojula webanga eliphakathi nendawo, namamojula optical amabanga amade.I-optical module yebanga elide iyimojula ye-optical enebanga lokudlulisela elingaphezu kuka-30km.Ekusetshenzisweni kwangempela kwemodyuli ye-optical yebanga elide, ibanga eliphakeme lokudlulisa lemoduli alikwazi ukufinyelelwa ezimweni eziningi.Lokhu kungenxa yokuthi isignali ye-optical izovela kunqubo yokudlulisela ye-fiber optical.Ukuze kuxazululwe le nkinga, imojula yebanga elide ye-optical module isebenzisa ubude begagasi obunye kuphela futhi isebenzisa i-laser ye-DFB njengomthombo wokukhanya, ngaleyo ndlela igwema inkinga yokuhlakazeka.

2. Izinhlobo zamamojula wokubuka webanga elide:

Kukhona amamojula optical obude obude phakathi kwamamojula we-SFP optical, amamojula we-SFP + optical, amamojula we-XFP optical, amamojula we-40G optical, amamojula we-40G optical, namamojula we-100G optical.Phakathi kwazo, imojuli ye-SFP + yebanga elide isebenzisa izingxenye ze-laser ye-EML kanye nezingxenye ze-photodetector.Ukuthuthukiswa okuhlukahlukene kuye kwanciphisa ukusetshenziswa kwamandla kwemodyuli ye-optical futhi kwathuthukisa ukunemba;Imojula yebanga elide ye-40G ye-optical module isebenzisa umshayeli kanye neyunithi yokushintshanisa kusixhumanisi sokudlulisa, futhi isixhumanisi esamukelayo sisebenzisa i-amplifier optical kanye neyunithi yokuguqula isithombe sikagesi, esingafinyelela ibanga eliphakeme lokudlulisela elingu-80km, elikhulu kakhulu kune-optical. Ibanga lokudlulisela lemojula ye-40G evamile exhumekeka kalula .

3.ukusetshenziswa kwamamojula optical amabanga amade:

a.Amachweba okushintsha kwezimboni
b.Imbobo yeseva
c.Imbobo yekhadi lenethiwekhi
d.Umkhakha wokuqapha ezokuphepha
Inkambu ye-e.Telecom, okuhlanganisa isikhungo sokulawula idatha, igumbi lekhompyutha, njll.
f.Ethernet (Ethernet), Fiber Channel (FC), Synchronous Digital Hierarchy (SDH), Synchronous Optical Network (SONET) nezinye izinkambu.

4. Izinyathelo zokuqapha zokusebenzisa amamojula okubona amabanga amade:

Amamojula okubona amabanga amade anezidingo eziqinile ebangeni lamandla okubonayo elamukelayo.Uma amandla okubona edlula ububanzi bokuzwela abatholayo, imojuli ye-optical izosebenza kabi.Ukusetshenziswa kanye nezinyathelo zokuphepha zimi kanje:
a.Ungaxhumi i-jumper ngokushesha ngemva kokufaka imojuli ye-optical yebanga elide engenhla kudivayisi, qala usebenzise umugqa womyalo obonisa ukuxilongwa kwe-transceiver.

Isixhumi esibonakalayo sifunda amandla okukhanya atholiwe wemojuli yokubona ukuze kuhlolwe ukuthi amandla okukhanya angaphakathi kwebanga elivamile.Amandla okukhanya atholiwe akulona inani elingavamile njenge +1dB.Uma i-optical fiber ingaxhumekile, isofthiwe ngokuvamile ibonisa ukuthi amandla okukhanya atholiwe angase abe -40dB noma inani eliphansi uma kuqhathaniswa.

b Uma kungenzeka, ungasebenzisa imitha yamandla okubona ukuze uhlole ukuthi amandla atholiwe nakhishiwe angaphakathi kwebanga elivamile lokwamukela ngaphambi kokuxhuma i-fiber optical module eshiwo ngenhla yebanga elide.

c.Ngaphansi kwezimo akufanele i-fiber optical iboshwe ngokuqondile ukuze kuhlolwe amamojula okubona amabanga amade ashiwo ngenhla.Uma kudingekile, i-optical attenuator kufanele ixhunywe ukwenza amandla okubona awamukelwe ngaphakathi kwebanga eliwamukelayo ngaphambi kokuthi kwenziwe ukuhlolwa kwe-loopback.

f.Uma usebenzisa imojuli ye-optical yebanga elide, amandla atholiwe kufanele abe nomkhawulo othile.Amandla angempela atholiwe abekelwe ngaphezu kuka-3dB uma kuqhathaniswa nokuzwela kokwamukela.Uma ingahlangabezani nezidingo, i-attenuator kufanele yengezwe.

g.Amamojula e-optical amabanga amade angasetshenziswa ezinhlelweni zokudluliswa kwe-10km ngaphandle kokuncishiswa.Ngokuvamile, amamojula angaphezu kuka-40km azoba nokuncishiswa futhi awakwazi ukuxhunywa ngokuqondile, ngaphandle kwalokho kulula ukushisa i-ROSA.
