Iko kumhanya kweiyo optical module SFP + ndeye: 10G SFP + optical transceiver inosimudzira yeSFP (dzimwe nguva inonzi "mini-GBIC"). SFP yakashandiswa zvakanyanya paGigabit Ethernet uye 1G, 2G, uye 4G Fiber Channel. Kuti ienderane kune yakakwirira data mareti, SFP + yakagadzira yakakwidziridzwa magetsi ekudzivirira uye masaini ekugadzirisa maitiro kupfuura SFP, uye yakagadzira mitsva yemagetsi interface.
Interface index yeSFP Optical module
1. Output optical power Output optical power inoreva simba rekubuda kwechiedza chechiedza pamagumo ekutumira optical module, unit: dBm.
2. Simba remagetsi rakagamuchirwa Rakagamuchira simba remagetsi rinoreva simba rakagamuchirwa remagetsi pamagumo ekugamuchira optical module, unit: dBm.
3. Gamuchira kunzwisiswa Kugashira kunzwisiswa kunoreva hushoma hwakagashirwa simba remaziso reiyo optical module pane imwe chiyero uye bit kukanganisa mwero, mudBm. Mumamiriro ezvinhu akajairwa, iyo yakakwira mwero, iyo yakaipisisa yekugamuchira senitivity, ndiko kuti, iyo yakakura iyo shoma inogashirwa simba rekuona, iyo yakakwirira iyo inodiwa yekugamuchira mudziyo weiyo optical module.
4. Saturated optical power, inozivikanwawo seOptical saturation, inoreva iyo yakanyanya kupinza simba rekuona kana imwe diki kukanganisa mwero (10-10).～10-12) inochengetwa pane imwe nhanho yekufambisa.
Izvo zvinofanirwa kucherechedzwa kuti iyo photodetector ichazadza iyo photocurrent pasi pechiedza chakasimba. Kana ichi chiitiko chikaitika, detector inoda imwe nguva yekupora. Panguva ino, kunzwisiswa kwekugamuchira kunoderera uye chiratidzo chinogamuchirwa chinogona kusanzwisiswa. Iyo inokonzeresa zvikanganiso zvishoma, uye zviri nyore kwazvo kukuvadza inogamuchira detector. Mukushandiswa, inofanira kuedza kudzivirira kudarika ayo akazara optical simba.
Ziva kuti kureba-kure-kure optical modules, sezvo avhareji inobuda optical simba kazhinji yakakura kupfuura iyo yakazara saturated optical simba, ndapota teerera kune kureba kwefiber paunenge uchiishandisa kuti uve nechokwadi chekuti iyo yakagashirwa optical simba inosvika iyo optical module. ishoma pane simba rayo rekuona rakazara. Iyo optical module yakakuvadzwa.
Zvikamu zveSFP Optical modules
Kuumbwa kweSFP optical module ndeiyi: laser: inosanganisira transmitter TOSA uye inogamuchira ROSA redunhu bhodhi IC, uye zvekunze zvekushandisa ndezvi: shell, base, PCBA, dhonza mhete, buckle, kuvhura chidimbu, rabha plug. Pamusoro pezvo, kuti zvizivikanwe zviri nyore, Kazhinji, iyo parameter mhando yemodule inotaridzwa nemuvara weinodhonza mhete. Semuenzaniso: dema rekudhonza mhete ine multi-mode, iyo wavelength i850nm; bhuruu ndiyo module ine wavelength ye1310nm; iyo yero ndiyo module ine wavelength ye1550nm; iyo yepepuru ndiyo module ine wavelength ye1490nm.
SFP, SFF uye GBIC optical module hukama
SFP ndiyo chidimbu cheDiki Form-factor Pluggables, kureva, diki pasuru inovharika optical module. SFP inogona kutariswa senge pluggable vhezheni yeSFF. Iyo yemagetsi interface ndeye 20-pini yegoridhe chigunwe. Iyo data chiratidzo chekushandisa chakangofanana neiyo SFF module. Iyo SFP module inopawo I2C control interface, inoenderana neSFP-8472 yakajairwa optical interface diagnostics. Ose ari maviri SFF neSFP haasanganisire SerDes chikamu, uye anongopa serial data interface. Iyo CDR uye yemagetsi dispersion muripo anoiswa kunze kwemodule, ichiita diki saizi uye yakaderera simba kushandiswa zvinogoneka. Nekuda kwekudzikisira kwekupisa kupisa, SFF/SFP inogona kungoshandiswa kune yekupedzisira-ipfupi chinhambwe, chinhambwe chipfupi uye chepakati dhizaini maapplication pa2.5Gbps uye pazasi.
SFP optical modules ikozvino ine yakanyanya kumhanya ye10G, uye yakawanda inoshandisa LC interfaces. Inogona kungonzwisiswa seyakakwidziridzwa vhezheni yeGBIC. Huwandu hweSFP optical modules hwakaderedzwa nehafu kana ichienzaniswa neGBIC optical modules, uye inodarika kaviri nhamba yezvikepe inogona kugadzirwa pane imwechete panel. Panyaya yemamwe mabasa, iyo yakakosha yeSFP module yakafanana neGBIC. Naizvozvo, zvimwechinjavagadziri vanodaidza SFP optical modules miniaturized GBIC.
