Muamua, o le malamalama faavae o le module optical
1. Fa'amatalaga:
Optical module: o lona uiga, le module transceiver optical.
2. Fauga:
O le module transceiver opitika e aofia ai se masini optoelectronic, o se matagaluega galue ma se faʻaoga mata, ma o le masini optoelectronic e aofia ai vaega e lua: felauaiga ma le mauaina.
O le vaega o le felauaiga o le: o se faailo eletise o loʻo faʻapipiʻiina se fua faʻatatau o loʻo faʻagasoloina e se vaʻa avetaʻavale i totonu e ave ai se semiconductor laser (LD) poʻo se moli emitting diode (LED) e faʻaosoina ai se faʻailoga malamalama faʻapipiʻiina o se fua faatatau tutusa, ma se mea faʻapitoa. mana otometi fa'atonutonu matagaluega o lo'o tu'uina atu totonu i totonu. O lo'o tumau pea le malosi o le fa'ailo opitika.
O le vaega o le mauaina o le: o se masini faʻapipiʻi faʻailoga faʻapipiʻi o se fua faʻatatau code ua liua i se faʻailoga eletise e le photodetecting diode. A maeʻa le preamplifier, o le faʻailoga eletise o le fua faʻatatau o le numera o loʻo gaosia, ma o le faʻailoga e masani lava ona maualuga PECL. I le taimi lava e tasi, o se fa'ailo fa'ailo o lo'o gaosia pe a uma le fa'aogaina o le mana opitika e itiiti ifo nai lo se tau fa'apitoa.
3.le tapula'a ma le taua o le module optical
Optical modules e tele mea taua faʻapitoa faʻapitoa faʻapitoa. Ae ui i lea, mo le lua vevela-swappable modules, GBIC ma le SFP, o vaega nei e tolu e sili ona popole pe a filifilia:
(1) Galulue ogatotonu
I nanometers (nm), e tolu ituaiga autu i le taimi nei:
850nm (MM, multimode, tau maualalo ae puʻupuʻu felauaiga mamao, masani na o 500M); 1310nm (SM, tulaga tasi, gau tele i le taimi o felauaiga ae laʻititi faʻasalalau, e masani ona faʻaaogaina mo le faʻasalalauga i totonu ole 40KM);
1550nm (SM, tulaga tasi, maualalo gau i le taimi o le felauaiga ae tele faʻasalalau, e masani ona faʻaaogaina mo le mamao mamao i luga ole 40KM, ma e mafai ona tuʻu saʻo le 120KM e aunoa ma le faʻasalalau);
(2) Fa'asalalauga fua
Ole aofa'i o pa'u (bits) o fa'amaumauga e tu'uina atu ile sekone, ile bps.
O lo'o i ai nei ituaiga e fa e masani ona fa'aaogaina: 155 Mbps, 1.25 Gbps, 2.5 Gbps, 10 Gbps, ma isi. Ole fua ole felauaiga e masani ona fetaui i tua. O le mea lea, o le 155M optical module e taʻua foi o le FE (100 Mbps) module optical, ma le 1.25G optical module e taʻua foi o le GE (Gigabit) optical module.
O le fa'aoga sili lea ona fa'aaogaina i masini fa'asalalau. E le gata i lea, o lona faʻasalalauga i totonu o le fiber storage systems (SAN) o le 2Gbps, 4Gbps ma le 8Gbps.
(3) Faʻasalalauga mamao
E le manaʻomia ona faʻafeiloaʻi le faʻailoga mata i se mamao e mafai ona tuʻu saʻo, i kilomita (e taʻua foi o kilomita, km). E masani ona iai faʻamatalaga faʻapitoa: multimode 550m, mode tasi 15km, 40km, 80km, ma le 120km, ma isi.
