Ngokombono wabantu abaningi, iyini i-optical module? Abanye abantu baphendule bathi: ayikhiwanga ngedivayisi ye-optoelectronic, ibhodi le-PCB kanye nendlu, kodwa yini enye eyenzayo?
Eqinisweni, ukuze kube sobala, i-optical module yakhiwe izingxenye ezintathu: amadivayisi e-optoelectronic (i-TOSA, i-ROSA, i-BOSA), i-optical interface (izindlu) kanye nebhodi le-PCB. Okwesibili, umsebenzi wayo ukuguqula isignali kagesi ibe isignali ye-optical kusukela ekugcineni kokudlulisa. Ngemva kokudlulisa nge-optical fiber, ingxenye yokwamukela iguqula isignali ye-optical ibe isignali kagesi, okumane kuyisici se-elekthronikhi sokuguqulwa kwe-photoelectric.
Kodwa mhlawumbe ubungalindele ukuthi ububanzi bokusetshenziswa kwamamojula e-optical fiber bubanzi kangaka. Namuhla, i-ETU-LINK izokhuluma nawe ngokuthi amamojula e-optical fiber asetshenziswa kuluphi ububanzi kanye nemishini.
Okokuqala, amamojula e-optical fiber asetshenziswa kakhulu emishinini elandelayo:
1. I-transceiver yefayibha yokukhanya
Le transceiver yefayibha ye-optical isebenzisa amamojula e-optical angu-1*9 kanye ne-SFP, asetshenziswa kakhulu kuma-intranet ezinkampani, kuma-cafe e-inthanethi, emahhotela e-IP, ezindaweni zokuhlala nakwezinye izinkambu, futhi ububanzi bezicelo bubanzi kakhulu. Ngesikhathi esifanayo, inkampani yethu ayigcini nje ngokuthengisa amamojula e-optical, izintambo, ama-jumper neminye imikhiqizo, kodwa futhi ilungiselela eminye imikhiqizo ehambisanayo, njenge-transceivers, ama-pigtails, ama-adapters nokunye.
2. Shintsha
I-Switch (isiNgisi: I-Switch, okusho ukuthi “i-switch”) iyidivayisi yenethiwekhi esetshenziselwa ukudlulisa isignali kagesi, ikakhulukazi kusetshenziswa ama-port kagesi, amamojula we-optical angu-1*9, i-SFP, i-SFP+, i-XFP, njll.
Inganikeza indlela ekhethekile yesignali kagesi yanoma yimaphi ama-node amabili enethiwekhi axhunywe kuswishi. Phakathi kwawo, amaswishi avame kakhulu amaswishi e-Ethernet, alandelwe amaswishi ezwi ocingweni, amaswishi e-optical fiber, njll., futhi sineziswishi zomkhiqizo ezingaphezu kuka-50. Amamojula e-optical azohlolwa ukuthi ayahambisana namadivayisi angempela ngaphambi kokuba ashiye ifektri, ngakho ikhwalithi iphezulu. Ungaqiniseka.
3. Ikhadi lenethiwekhi yefayibha yokukhanya
Ikhadi lenethiwekhi ye-Fiber optic liyi-adaptha ye-Ethernet ye-fiber optic, ngakho-ke libizwa ngokuthi ikhadi lenethiwekhi ye-fiber optic, ikakhulukazi lisebenzisa i-module ye-optical engu-1*9, i-module ye-optical ye-SFP, i-module ye-optical ye-SFP+, njll.
Ngokwesilinganiso sokudlulisa, ingahlukaniswa ibe yi-100Mbps, 1Gbps, 10Gbps, ngokwezinhlobo zesokhethi lebhodi le-motherboard ingahlukaniswa ibe yi-PCI, PCI-X, PCI-E (x1/x4/x8/x16), njll., ngokwezinhlobo zesikhombimsebenzisi ihlukaniswe ibe yi-LC, SC, FC, ST, njll.
4. Umshini webhola osheshayo we-fiber optical
I-fibre optic high-speed dome isebenzisa kakhulu amamojula e-SFP optical, kanti i-fibre optic high-speed dome, ngamagama alula, iyindawo engaphambili yekhamera ehlakaniphile. Iyindawo engaphambili yekhamera esebenza kahle kakhulu futhi ephelele ohlelweni lokuqapha. I-fibre optic high-speed dome ikwi-dome ephansi. Imojula yeseva yevidiyo yenethiwekhi ehlanganisiwe noma imojula ye-transceiver ebonakalayo.
5. Isiteshi sesisekelo
Isiteshi esiyisisekelo sisebenzisa kakhulu amamojula e-optical e-SFP, SFP+, XFP, SFP28. Ohlelweni lokuxhumana oluhambayo, ingxenye egxilile kanye nengxenye engenantambo kuxhunyiwe, kanti imishini ixhunywe esiteshini esihambayo ngokudluliselwa okungenantambo emoyeni. Ngokuthuthuka kokwakhiwa kweziteshi eziyisisekelo ze-5G, imojula ye-optical Imboni nayo ifinyelele enkathini yokufunwa kokukhiqiza.
6. I-router yefayibha yokukhanya
Ama-router e-optical fiber ngokuvamile asebenzisa amamojula e-SFP optical. Umehluko phakathi kwawo nama-router avamile ukuthi i-transmission medium ihlukile. I-network port yama-router avamile isebenzisa i-twisted pair njenge-transmission medium, kanti ikhebula lenethiwekhi elikhiphayo liyisignali kagesi; kanti i-network port ye-optical fiber router Isebenzisa i-optical fiber, engasetshenziswa ukuhlaziya isignali ye-optical kwi-home fiber.
Okwesibili, kunezindlela eziningi zokusebenzisa amamojula e-optical fiber, njenge:
1.Uhlelo lwesitimela. Kunethiwekhi yesistimu yokuxhumana yesistimu yesitimela, ukusetshenziswa kobuchwepheshe bokuxhumana ngefayibha ye-optical kuhlala kudlala indima ebalulekile. Akugcini nje ngokuthuthukisa ukusebenza kahle kokuxhumana ngefayibha ye-optical evamile, kodwa futhi kungathuthukisa ukusebenza kahle kokusetshenziswa kolwazi kunethiwekhi yokuxhumana ngesitimela ngenxa yezinzuzo zayo ezinhle zokuzinza kokudluliselwa kwedatha.
2.Ukuqapha ithrafikhi yemihubhe. Njengoba inqubo yokufudukela emadolobheni iqhubeka nokusheshisa, ukuhamba kwabantu basemadolobheni kuncike kakhulu esitimeleni esingaphansi komhlaba. Kubalulekile ukuqinisekisa ukuphepha kwesitimeleni esingaphansi komhlaba. Ukusetshenziswa kwe-optical fiber ezwa ukushisa emihubheni engaphansi komhlaba kungadlala indima ngempumelelo ekuxwayiseni ngomlilo.
Ngaphezu kwalokho, ububanzi bokusetshenziswa kwamamojula e-optical busesezinhlelweni zokuthutha ezihlakaniphile, ezenzakalelayo zokwakha, abahlinzeki bezixazululo zenethiwekhi ye-ISP kanye namanethiwekhi ezimoto. Akuzona nje kuphela izintambo ze-optical ezingasetshenziswa ekudluliseni ukuxhumana, kodwa amamojula e-optical nawo agcina isikhala nezindleko, futhi alula futhi ashesha.
Ngesikhathi esifanayo, njengensika eyinhloko yokushintshana kolwazi lwesimanje, ukucubungula kanye nokudlulisa, inethiwekhi yokuxhumana ye-optical ibilokhu ithuthuka njalo ifinyelela kumthamo wemvamisa ephezulu kakhulu, isivinini esikhulu kakhulu kanye nomthamo omkhulu kakhulu. Lapho izinga lokudlulisa liphezulu, umthamo omkhulu, kanye nezindleko zokudlulisa ulwazi ngalunye ziya ngokuya zincipha. Ukuze kuhlangatshezwane nezidingo zemishini yokuxhumana yesimanje, amamojula e-optical fiber nawo athuthuka abe amaphakheji amancane ahlanganiswe kakhulu. Izindleko eziphansi, ukusetshenziswa kwamandla okuphansi, isivinini esikhulu, ibanga elide, kanye nokuxhuma okushisayo nakho kuyizindlela zokuthuthukiswa kwayo.
