Kutanga, ruzivo rwekutanga rweiyo optical module
1. Tsanangudzo:
Optical module: kureva, iyo optical transceiver module.
2.Structure:
Iyo optical transceiver module inoumbwa neiyo optoelectronic mudziyo, inoshanda dunhu uye optical interface, uye optoelectronic mudziyo unosanganisira zvikamu zviviri: kutumira uye kugamuchira.
Chikamu chekufambisa ndeichi: chiratidzo chemagetsi chinopinza imwe kodhi chiyero chinogadziriswa nechomukati chekutyaira chip kutyaira semiconductor laser (LD) kana mwenje emitting diode (LED) kuburitsa modulated mwenje chiratidzo chechiyero chinoenderana, uye optical. simba otomatiki kudzora redunhu iri mukati inopiwa imomo.Iyo yakabuda optical chiratidzo simba rinoramba rakagadzikana.
Chikamu chekugamuchira ndechekuti: optical sign input module yeimwe code rate inoshandurwa kuita chiratidzo chemagetsi neiyo photodetecting diode.Mushure meiyo preamplifier, chiratidzo chemagetsi cheyero yekodhi inoenderana inobuda, uye chiratidzo chekubuda chinowanzo PECL level.Panguva imwecheteyo, chiratidzo chealarm chinobuda mushure mekuisa simba remagetsi risingasviki pane imwe kukosha.
3.the parameters uye kukosha kweiyo optical module
Optical modules ane akawanda akakosha optoelectronic technical parameters.Nekudaro, kune maviri anopisa-swappable optical modules, GBIC uye SFP, anotevera maparamita matatu anonyanya kunetseka pakusarudza:
(1) Center wavelength
Mune nanometers (nm), pane ikozvino mhando nhatu huru:
850nm (MM, multimode, yakaderera mutengo asi pfupi yekufambisa kureba, kazhinji chete 500M);1310nm (SM, single mode, kurasikirwa kukuru panguva yekufambisa asi kupararira kudiki, kunowanzo shandiswa kutapurirana mukati me40KM);
1550nm (SM, single mode, kurasikirwa kwakaderera panguva yekufambisa asi kupararira kukuru, kunowanzo shandiswa kuendesa kure-kure pamusoro pe40KM, uye inogona kutumira zvakananga 120KM pasina relay);
(2) Chiyero chekufambisa
Huwandu hwemabhiti (bits) e data inofambiswa pasekondi, mu bps.
Parizvino kune marudzi mana anowanzoshandiswa: 155 Mbps, 1.25 Gbps, 2.5 Gbps, 10 Gbps, nezvimwe zvakadaro.Mwero wekutapurirana unowanzo dzokera kumashure unoenderana.Nokudaro, 155M optical module inonziwo FE (100 Mbps) optical module, uye 1.25G optical module inonziwo GE (Gigabit) optical module.
Iyi ndiyo module inonyanya kushandiswa mune optical transmission equipment.Mukuwedzera, chiyero chayo chekufambisa mufiber storage systems (SAN) ndeye 2Gbps, 4Gbps uye 8Gbps.
(3) Kutapurirana kureba
Chiratidzo chemaziso hachidi kuendeswa kune chinhambwe chinogona kufambiswa zvakananga, mumakiromita (anonziwo makiromita, km).Optical modules kazhinji ane zvinotevera zvinotsanangurwa: multimode 550m, single mode 15km, 40km, 80km, uye 120km, zvichingodaro.
