(i) Ubude bombindi
Ubude obusebenzayo bemodyuli ye-optical eneneni luluhlu, kodwa kuya kubakho umahluko ocacileyo phakathi kwemowudi enye kunye nemowudi eninzi. Emva koko eli binzana lithiywa ngokubanzi ngokona bude buphakathi.
Iyunithi yobude obusembindini yinanometer (nm),
Iziko lobude obuqhelekileyo yi-850nm, 1310nm kunye ne-1550nm, njl.
I-1) 850nm (MM, i-multi-mode, ixabiso eliphantsi (amacandelo e-optical angabizi) kodwa umgama omfutshane wokuhanjiswa (ukuhanjiswa kweendlela ezininzi, impembelelo ehambelanayo phakathi kwamaza ahlukeneyo), ngokubanzi kuphela i-500m ukuya kwi-3KM);
I-2) i-1310nm (i-SM, i-mode-mode, ilahleko enkulu ngexesha lokudluliselwa, kulula ukufumana amandla ngokusasazwa okuphakathi kodwa okuncinci, okusetyenziselwa ukuhanjiswa ngaphakathi kwe-40km);
3) I-1550nm (i-SM, imowudi enye, ilahleko encinci kodwa i-dispersion enkulu ngexesha lokudluliselwa, ngokuqhelekileyo isetyenziselwa ukuhanjiswa komgama omde ngaphezu kwe-40km, ukuya kwi-120km ngaphandle kokudluliselwa).
(ii) Umgama wothumelo
Ngenxa yokuba i-fiber optical ngokwayo inemiphumo emibi efana nokusabalalisa, ukulahleka, kunye nokulahlekelwa kokufakwa kwisignali ye-optical. Ngoko ke, imigama ekunokuhamba kuyo ukukhanya okukhutshwa ziintlobo ezahlukeneyo zemithombo yokukhanya yahlukile. Xa udibanisa i-optical interfaces, khetha iimodyuli ze-optical kunye neefibers ze-optical ngokomgama ode kakhulu wokuhambisa umqondiso. Umgama wokuhanjiswa kwemodyuli ye-optical ihlukaniswe kwiintlobo ezintathu: umgama omfutshane, umgama ophakathi kunye nomgama omde. Ngokuqhelekileyo kuqwalaselwa ukuba i-2km nangaphantsi yimigama emifutshane, i-10 ukuya kwi-20km yimigama ephakathi, kunye ne-30km nangaphezulu yimigama emide.
(iii) Isantya sothumelo
Izinga lothumelo libhekiselele kwinani leebhithi (iibhithi) zedatha ethunyelwa ngesekhondi, kwi-bps. Izinga lokudluliselwa liphantsi njenge-100M, ukuya kwi-400Gbps, kwaye amaxabiso asetyenziswa ngokuqhelekileyo yi-155Mbps, 1.25Gbps, 10Gbps, 25Gbps, 40Gbps, 100Gbps njalo njalo. Ukongeza, kukho iireyithi ezintathu ze-2Gbps, i-4Gbps kunye ne-8Gbps iimodyuli ze-optical kwi-system yokugcina optical (SAN).
Oku kungasentla kulwazi lweparam ezintathu eziphambiliii-eters zeemodyuli zamehlo eziziswa nguShenzhen Haidiwei Optoelectronics Technology Co., Ltd. Iimveliso zemodyuli eziveliswe yikhava yenkampani. iimodyuli zefiber optical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl. Ezi mveliso zemodyuli zingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi. Iqela le-R&D elinobuchule kunye nelomeleleyo linokunceda abathengi abanemiba yobugcisa, kwaye iqela leshishini elicingayo nelinobuchule linokunceda abathengi bafumane iinkonzo ezikumgangatho ophezulu ngexesha lokubonisana kwangaphambili kunye nomsebenzi wasemva kokuvelisa. Wamkelekile kuwe Qhagamshelana nathi kulo naluphi na uhlobo lombuzo.
