Iyo SFP Module ine optical mudziyo, inoshanda dunhu uye optical interface.Iyo optical mudziyo inosanganisira kutumira uye kugamuchira zvikamu.
Chikamu chekutumira ndechekuti: kupinza kweimwe kodhi chiyero chemagetsi masaini, kuburikidza nemukati mutyairi chip processing, kutyaira semiconductor laser (LD) yechiedza emitting diode (LED) kutumira inoenderana kodhi chiyero modulation optical chiratidzo, chiedza chemukati chiri yakapihwa ine otomatiki magetsi ekugadzirisa dhizaini.Iyo yakabuda optical chiratidzo simba rinoramba rakagadzikana.
Chikamu chekugamuchira ndechekuti: iyo optical sign input module yeimwe kodhi chiyero inoshandurwa kuita chiratidzo chemagetsi kuburikidza neiyo optical yekuona diode.Mushure meiyo preamplifer, chiratidzo chinobuda cheiyo inoenderana bit chiyero ndeye PECL level.Kana iyo yekupinza yemagetsi ishoma pane imwe kukosha, chiratidzo chealarm chinogadzirwa.
Parameters uye zvinoreva optical modules
Iwo maOptical modules aive neakakosha optical technical parameters.Nekudaro, kune GBIC uye SFP inopisa-plug SFP Modules, iwe unofanirwa kuterera kune matatu anotevera paramita.
Kubva pane nanometer(nm), kune marudzi matatu makuru parizvino.
850nm (MM, akawanda-modhi, yakaderera mutengo asi pfupi yekufambisa kureba, kazhinji chete 500M).
1310nm (SM, Single Mode, kurasikirwa kudiki kwekutapurirana, kupararira kukuru, kunowanzo shandiswa kufambisa kureba pamusoro pe40KM, hapana relay inogona kufambisa zvakananga 120KM).
1550nm (SM, Single Mode, kurasikirwa kwekutapurirana kudiki, kupararira kukuru, kunowanzo shandiswa kufambisa kureba pamusoro pe40KM, hapana replay yakananga kuendesa 120KM).
Transmission Rate
Nhamba dzebhiti (BPS) yedata inofambiswa pasekondi.
Parizvino.Kune mana anowanzo shandiswa SFP Modules.155Mbps, 1.25Gbps, 2.5Gbps, 10Gbps uye zvichingodaro.Chiyero chekufambisa chinowanzo dzokera kumashure.Naizvozvo, 155M SFP Module inonziwo FE (100Mbit/s) SFP Module, uye 1.25G SFP Module inonziwo GE (Gigabit) optical module.
Iyi ndiyo inonyanya kushandiswa SFP mune optical transmission equipment.Pamusoro pezvo, mitengo yayo yekufambisa mufiber optic storage systems (SAN) ndeye 2Gbps, 4Gbps, uye 8Gbps.
Transmission distance
Chiratidzo cheOptical hachidi kuendeswa kune chinhambwe kwaanogona kutapurirwa zvakananga.Mumakiromita (anonziwo makiromita, KM).Zvinotsanangurwa zveSFP Modules ndeizvi: Multi-Mode 550M, Single-Mode 15KM, 40KM, 80KM, uye 120KM, nezvimwe.
