(i) Ubude begagasi obumaphakathi
Ubude begagasi obusebenzayo bemojuli ye-optical empeleni buwububanzi, kodwa kuzoba nomehluko osobala phakathi kwemodi eyodwa kanye nemodi eminingi. Khona-ke lesi sisho ngokuvamile siqanjwa ngokuvumelana ne-wavelength emaphakathi kakhulu.
Iyunithi ye-wavelength emaphakathi yi-nanometer (nm),
Amaza esikhungo ajwayelekile angu-850nm, 1310nm no-1550nm, njll.
I-1) 850nm (MM, imodi eminingi, izindleko eziphansi (izingxenye ze-optical zishibhile) kodwa ibanga elifushane lokudlulisela (ukudluliselwa kwemodi eminingi, ithonya elihlangene phakathi kwamaza ahlukene), ngokuvamile kuphela i-500m kuya ku-3KM kuphela);
I-2) i-1310nm (i-SM, imodi eyodwa, ukulahlekelwa okukhulu ngesikhathi sokudlulisela, kulula ukumunca amandla ngokuhlakazeka okuphakathi kodwa okuncane, okuvame ukusetshenziselwa ukudluliselwa ngaphakathi kwe-40km);
3) 1550nm (SM, imodi eyodwa, ukulahlekelwa okuncane kodwa ukuhlakazeka okukhulu ngesikhathi sokudlulisa, ngokuvamile kusetshenziselwa ukudlulisa ibanga elide ngaphezu kuka-40km, kufika ku-120km ngaphandle kokudluliselwa).
(ii) Ibanga lokudlulisela
Ngoba i-fiber optical ngokwayo inemiphumela emibi njengokuhlakazeka, ukulahlekelwa, nokulahlekelwa kokufaka kusiginali ye-optical. Ngakho-ke, amabanga angahamba ukukhanya okukhishwa izinhlobo ezahlukene zemithombo yokukhanya ahlukile. Lapho uxhuma i-optical interfaces, khetha amamojula abonakalayo namafiber optical ngokuya ngebanga elikude kakhulu lokudlulisa isignali. Ibanga lokudlulisela lemojula ye-optical lihlukaniswe ngezinhlobo ezintathu: ibanga elifushane, ibanga eliphakathi kanye nebanga elide. Ngokujwayelekile kubhekwa ukuthi amabanga ama-2km nangaphansi amabanga amafushane, amabanga aphakathi kuka-10 kuya ku-20 kanti amabanga amade angu-30km kuya phezulu.
(iii) Izinga lokudlulisela
Izinga lokudlulisela libhekisela enanini lamabhithi (amabhithi) edatha adluliswa ngomzuzwana, ngama-bps. Izinga lokudlulisela liphansi njenge-100M, lifika ku-400Gbps, futhi amanani avame ukusetshenziswa yi-155Mbps, 1.25Gbps, 10Gbps, 25Gbps, 40Gbps, 100Gbps njalonjalo. Ngaphezu kwalokho, kunamazinga amathathu we-2Gbps, 4Gbps kanye ne-8Gbps amamojula optical ohlelweni lwe-optical storage (SAN).
Okungenhla ulwazi lwama-param amathathu amakhuluama-eters amamojula okubona alethwe yi-Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. Imikhiqizo yemojuli ekhiqizwe ikhava yenkampani amamojula we-fiber optical, Amamojula we-Ethernet, amamojula we-fiber optical transceiver, amamojula okufinyelela kwefiber optical, Amamojula we-SSFP optical, futhiImicu ye-Optical SFP, njll. Imikhiqizo yemojula engenhla inganikeza ukwesekwa kwezimo zenethiwekhi ezahlukene. Ithimba le-R&D elichwepheshile neliqinile lingasiza amakhasimende anezinkinga zobuchwepheshe, futhi ithimba lebhizinisi elicabangayo nelichwepheshile lingasiza amakhasimende ukuthi athole amasevisi ekhwalithi ephezulu ngesikhathi sokubonisana kwangaphambilini nomsebenzi wangemuva kokukhiqiza. Siyakwamukela ku Xhumana nathi nganoma yiluphi uhlobo lombuzo.
