I le aotelega o fesoʻotaʻiga faʻamatalaga faʻaonaponei, o fesoʻotaʻiga fiber opitika o loʻo nofoia se tulaga iloga.Faatasi ai ma le faʻateleina o fesoʻotaʻiga o fesoʻotaʻiga ma le faʻaauauina pea o le gafatia o fesoʻotaʻiga, o le faʻaleleia atili o fesoʻotaʻiga fesoʻotaʻiga o se atinaʻe e le maalofia.Optical modulesiloa fa'ailoga optoelectronic i feso'ota'iga feso'ota'iga opitika.O le liua o se tasi o vaega autu o fesoʻotaʻiga fiber optical.Ae ui i lea, e masani ona matou talanoa e uiga i modules opitika.O lea la, o le a le tapula'a o modules opitika?

I le maeʻa ai o tausaga o atinaʻe, o masini faʻapipiʻi ua matua suia a latou auala faʻapipiʻi.SFP, GBIC, XFP, Xenpak, X2, 1X9, SFF, 200 / 3000pin, XPAK, QAFP28, ma isi mea uma o ituaiga faʻapipiʻi module optical;ae maualalo-saoasaoa , 100M, Gigabit, 2.5G, 4.25G, 4.9G, 6G, 8G, 10G, 40G, 100G, 200G ma e oo lava i le 400G o le felauaiga fua o modules opitika.
I le faʻaopoopoga i luga o faʻamaufaʻailoga faʻapipiʻi masani masani, o loʻo i ai mea nei:

1. Ole umi ole galu
Ole iunite ole umi ole galu ole nanometer (nm), ile taimi nei e tolu ituaiga autu:
1) 850nm (MM, tele-mode, tau maualalo ae puʻupuʻu mamao felauaiga, e masani lava na o le 500m felauaiga);
2) 1310nm (SM, tulaga tasi, gau tele ae laʻititi faʻasalalau i le taimi o faʻasalalauga, e masani ona faʻaaogaina mo le faʻasalalauga i totonu ole 40km);
3) 1550nm (SM, tasi-mode, maualalo gau ae tele faʻasalalau i le taimi o faʻasalalauga, e masani ona faʻaaogaina mo le mamao mamao i luga aʻe o le 40km, ma le mamao e mafai ona tuʻu saʻo e aunoa ma le faʻasalalau mo 120km).

2. Fa'asalalauga mamao
Feso'ota'iga mamao e fa'atatau i le mamao e mafai ona tu'u sa'o ai fa'ailo fa'apitoa e aunoa ma le fa'ateleina o fa'asalalauga.Ole iunite ole kilomita (e ta'ua foi o kilomita, km).Optical modules e masani ona i ai faʻamatalaga nei: tele-mode 550m, tasi-mode 15km, 40km, 80km, 120km, ma isi. Faatali.

3. gau ma fa'asalalauina: E fa'aa'afia uma le mamao fa'asalalau o le fa'aogaina o masini.E masani lava, o le gau o fesoʻotaʻiga e faʻatatau i le 0.35dBm / km mo le 1310nm module optical, ma le fesoʻotaʻiga gau e faʻatatau i le 0.20dBm / km mo le 1550nm optical module, ma o le tau faʻasalalau e faʻatatau E faigata tele, masani mo naʻo faʻamatalaga;

4. gau ma chromatic dispersion: O nei taʻiala e lua e masani ona faʻaaogaina e faʻamalamalama ai le mamao o le tuʻuina atu o le oloa.Ole malosi ole fa'aliliuga fa'apitoa ma le mauaina o le fa'alogoina o masini fa'apitoa o galu eseese, fua fa'atatau ma mamao fa'asalalau o le a eseese;

5. Vaega leisa: I le taimi nei, o laisa e masani ona faʻaaogaina o le FP ma le DFB.E ese'ese mea e fa'aogaina ai le semiconductor ma le resonator structure o ia mea e lua.DFB lasers e taugata ma e masani ona faʻaaogaina mo masini faʻapipiʻi ma se mamao faʻasalalau e sili atu i le 40km;a'o FP lasers e taugofie, E masani ona fa'aaogaina mo masini fa'apipi'i fa'atasi ma le mamao fa'asalalau e itiiti ifo i le 40km.

6. Optical fiber interface: SFP optical modules o fesoʻotaʻiga LC uma, GBIC modules optical o fesoʻotaʻiga SC uma, ma isi fesoʻotaʻiga e aofia ai FC ma ST, ma isi;

7. O le ola tautua o le module optical: o le tulaga faʻavaomalo faʻavaomalo, 7 × 24 itula o galuega e le faʻalavelave mo 50,000 itula (tutusa ma 5 tausaga);

8. Siosiomaga: Galulue vevela: 0 ~ + 70 ℃;Teuga vevela: -45 ~ + 80 ℃;Galulue voltage: 3.3V;Tulaga galue: TTL.
