Muchidimbu chemazuva ano ruzivo network, optical fiber kutaurirana inotora chinzvimbo chikuru.Nekuwedzera kuvharika kwetiweki uye nekuenderera mberi kwekuwedzera kwesimba rekutaurirana, kuvandudzwa kwezvekutaurirana zvinongedzo zvakare budiriro isingadzivisiki.Optical modulesziva masaini eoptoelectronic mune optical communication network.Iko kutendeuka ndechimwe chezvikamu zvikuru zve optical fiber communication.Nekudaro, isu tinowanzo kutaura nezve optical modules.Saka, ndeapi maparameter e optical modules?

Mushure memakore ebudiriro, optical modules akachinja zvakanyanya nzira dzekurongedza.SFP, GBIC, XFP, Xenpak, X2, 1X9, SFF, 200/3000pin, XPAK, QAFP28, nezvimwe zvose zviri optical module packaging types;nepo low-speed , 100M, Gigabit, 2.5G, 4.25G, 4.9G, 6G, 8G, 10G, 40G, 100G, 200G uye kunyange 400G ndiyo mitero yekufambisa ye optical modules.
Kuwedzera kune ari pamusoro akajairwa optical module paramita, pane zvinotevera:

1. Center wavelength
Iyo unit yepakati wavelength ndeye nanometer (nm), parizvino kune matatu makuru marudzi:
1) 850nm (MM, multi-mode, yakaderera mutengo asi pfupi kufambisa kureba, kazhinji chete 500m kutapurirana);
2) 1310nm (SM, single mode, kurasikirwa kukuru asi kupararira kudiki panguva yekufambisa, kunowanzo shandiswa kutapurirana mukati me40km);
3) 1550nm (SM, single-mode, kurasikirwa kwakaderera asi kupararira kukuru panguva yekufambisa, inowanzo shandiswa kuendesa kure-kure pamusoro pe40km, uye kureba kunogona kutapurirwa zvakananga pasina relay ye120km).

2. Kuendesa kure
Chinhambwe chekufambisa (transmission distance) chinoreva chinhambwe icho masaini anogona kufambiswa zvakananga pasina relay amplification.Chikwata ichi makiromita (anonziwo makiromita, km).Optical modules kazhinji ane zvinotevera zvinotsanangurwa: multi-mode 550m, single-mode 15km, 40km, 80km, 120km, etc. Mira.

3. Kurasikirwa uye kupararira: Zvose zvinonyanya kukanganisa kureba kwekufambisa kweiyo optical module.Kazhinji, kurasikirwa kwekubatanidza kunoverengerwa pa 0.35dBm/km ye1310nm optical module, uye kurasikirwa kwekubatanidza kunoverengerwa pa 0.20dBm/km ye1550nm optical module, uye kukosha kwekuparadzira kunoverengerwa Zvakanyanya kuoma, kazhinji kutariswa chete;

4. Kurasikirwa uye chromatic dispersion: Aya maparamita maviri anonyanya kushandiswa kutsanangura kureba kwekutapurirana kwechigadzirwa.Iro optical transmission simba uye kugamuchira senitivity ye optical modules yewavelengths yakasiyana-siyana, kutengesa kutengesa uye kureba kwekufambisa kuchave kwakasiyana;

5. Laser category: Parizvino, anonyanya kushandiswa lasers iFP neDFB.Iyo semiconductor zvinhu uye resonator chimiro chezviviri zvakasiyana.MaDFB lasers anodhura uye anonyanya kushandiswa kune optical modules ane chinhambwe chekutumira chinodarika 40km;nepo FP lasers yakachipa, Inowanzo shandiswa kune optical modules ine chinhambwe chekufambisa chisingasviki 40km.

6. Optical fiber interface: SFP optical modules yose LC interfaces, GBIC optical modules ndeye SC interfaces, uye mamwe mainterfaces anosanganisira FC uye ST, nezvimwewo;

7. Upenyu hwebasa re optical module: chiyero cheunifomu yenyika yose, 7 × 24 maawa ekushanda kusina kukanganiswa kwemaawa 50,000 (akaenzana nemakore mashanu);

8. Zvakatipoteredza: Kushanda tembiricha: 0 ~ + 70 ℃;Kuchengetedza tembiricha: -45 ~ + 80 ℃;Kushanda magetsi: 3.3V;Chikamu chekushanda: TTL.
