Basic sumo ye optical module

Basic sumo ye optical module

Iyo optical module inoumbwa neoptoelectronic zvishandiso, anoshanda maseketi uye optical interfaces. Iyo optoelectronic zvishandiso zvinosanganisira zvikamu zviviri: kutumira uye kugamuchira. Muchidimbu, basa re optical module nderekushandura chiratidzo chemagetsi muchiratidzo che optical pamagumo ekutumira. Mushure mokunge chiratidzo chemaziso chinoparidzirwa kuburikidza nefiber optical, kuguma kwekugamuchira kunoshandura chiratidzo chemaziso muchiratidzo chemagetsi.

Chikamu chekufambisa ndeichi: chiratidzo chemagetsi chekupinza cheimwe chiyero chinogadziriswa nechomukati dhiraivha chip, uye yobva yatyaira semiconductor laser (LD) kana light emitting diode (LED) kuti ibudise iyo modulated optical chiratidzo chechiyero chinowirirana. Iyo yemukati optical simba otomatiki kudzora dunhu yakashongedzerwa kuchengetedza inobuda optical chiratidzo chesimba yakagadzikana.

Chikamu chinogashira ndeichi: iyo optical chiratidzo chekuisa module ine imwe chiyero chiyero inoshandurwa kuita chiratidzo chemagetsi neiyo optical yekuona diode, uye chiratidzo chemagetsi chine inoenderana bit rate inobuda mushure meiyo preamplifier.

-Basic pfungwa yeOptical module-

Port-optical module ndiro zita rakajairika remhando dzakasiyana dzemodule, kazhinji zvichireva optical transceiver integrated module.

-Kushanda kweOptical module-

Basa rayo nderokuziva kutendeuka pakati pezviratidzo zvemaziso uye zviratidzo zvemagetsi.

-Optical module chimiro-

An optical module inowanzo umbwa neye optical transmitter, optical receiver, functional circuit uye optical (yemagetsi) interface.

Pane inotumira, mutyairi chip anogadzira chiratidzo chemagetsi chepakutanga, obva atyaira semiconductor laser (LD) kana light emitting diode (LED) kuti ibudise yakagadziridzwa chiratidzo chemaziso.

Chiteshi chiri pamagumo ekugamuchira. Mushure mekunge chiratidzo chemaziso chapinda, chinoshandurwa kuita chiratidzo chemagetsi neiyo optical yekuona diode, yobva yaburitsa chiratidzo chemagetsi kuburikidza ne preamplifier.

-Optical mode classification-

-Kuvandudza nhoroondo ye optical mode-

-Kusuma kune optical module kurongedza-

Kune huwandu hwakasiyana hwekurongedza zviyero zve optical modules, kunyanya nekuti:

》Masipidhi ekuvandudza tekinoroji yefiber communication inomhanya zvakanyanya. Iko kumhanya kweiyo optical module iri kuwedzera, uye vhoriyamu iri kuderera zvakare, zvekuti makore mashoma ega ega, mavara matsva ekurongedza achapihwa.

yakarurama Izvo zvakare zvakaoma kuenderana pakati pezvitsva uye zvekare zvekurongedza zviyero.

》Mamiriro ekushandisa emamodule optical akasiyana. Yakasiyana yekufambisa madaro, bandwidth zvinodiwa, uye nzvimbo dzekushandisa, zvinoenderana nemhando dzakasiyana dzefiber fiber inoshandiswa, optical modules zvakare akasiyana.

Port GBIC

GBIC ndiyo Giga Bitrate Interface Converter.

Asati asvika 2000, GBIC ndiyo yaive yakanyanya kufarirwa optical module yekurongedza uye inonyanya kushandiswa gigabit module fomu.

Port SFP

Nekuda kwehukuru hukuru hweGBIC, SFP yakaonekwa gare gare ndokutanga kutsiva GBIC.

SFP, zita rizere reDiki Form-factor Pluggable, idiki rinopisa-swappable optical module. Hukuru hwayo hudiki hunoenderana neGBIC kurongedza. Saizi yeSFP idiki hafu pane iyo yeGBIC module, uye kanopfuura kaviri nhamba yezviteshi inogona kugadzirwa pane imwechete mapaneru. Panyaya yebasa, pane musiyano mudiki pakati pezviviri, uye zvese zvinotsigira kupisa plugging. Iyo yakakura bandwidth inotsigirwa neSFP ndeye 4Gbps

Oral XFP

XFP ndeye gumi-Gigabit Diki Form-factor Pluggable, iyo inogona kunzwisiswa nekungotarisa. Iyo 10-Gigabit SFP.

XFP inotora yakazara-speed single-channel serial module yakabatana neXFI (10Gb serial interface), iyo inogona kutsiva Xenpak uye zvinobva mairi.

Port SFP+

SFP+, seXFP, ndeye 10G optical module.

Saizi yeSFP + yakafanana neyeSFP. Iyo yakawanda compact kupfuura XFP (yakaderedzwa neanenge makumi matatu%), uye simba rayo rekushandisa idiki zvakare (rakaderedzwa nemamwe mabasa ekudzora chiratidzo).

O SFP28

SFP ine chiyero che 25Gbps inonyanya nokuti 40G uye 100G optical modules yaidhura zvakanyanya panguva iyoyo, saka iyi yekukanganisa shanduko chirongwa chakaitwa.

QSFP/QSFP+/QSFP28/QSFP28-DD

Quad Diki Form-factor Pluggable, ina-channel SFP interface. Mazhinji akakura makiyi matekinoroji muXFP akaiswa kune iyi dhizaini. QSFP inogona kukamurwa kuita 4 zvichienderana nekumhanya × 10G QSFP +, 4 × 25G QSFP28, 8 × 25G QSFP28-DD optical module, nezvimwe.

Tora QSFP28 semuenzaniso, iyo inoshanda kune 4 × 25GE yekupinda port. QSFP28 inogona kushandiswa kukwidziridza kubva ku25G kuenda ku100G isina 40G, kurerutsa zvakanyanya kuoma kwecabling uye kuderedza mari.

QSFP/QSFP+/QSFP28/QSFP28-DD

QSFP-DD, yakavambwa muna Kurume 2016, inoreva "Double Density". Wedzera mutsara wezviteshi kune 4 chiteshi cheQSFP uye uchinje kuva 8 chiteshi.

Inogona kuenderana neQSFP chirongwa. Iyo yekutanga QSFP28 module inogona achiri kushandiswa, ingoisa imwe module. Huwandu hweminwe yegoridhe yeOSFP-DD yakapetwa kaviri yeQSFP28.

Imwe neimwe QSFP-DD inotora 25Gbps NRZ kana 50Gbps PAM4 chiratidzo chimiro. NePAM4, inogona kutsigira kusvika ku400Gbps.

Iyo optical injini uye transceiver ine yakakwirira wattage ine zvishoma zvirinani kupisa kupisa kuita.

CFP/CFP2/CFP4/CFP8

Centum gigabits Form Pluggable, dense wavelength division optical communication module. Chiyero chekufambisa chinogona kusvika ku100-400Gbpso

CFP yakagadzirwa pahwaro hweSFP interface, ine hukuru hukuru uye inotsigira 100Gbps kutumira data. CFP inogona kutsigira imwechete 100G chiratidzo uye imwe kana kupfuura 40G zviratidzo.

Musiyano uripo pakati peCFP, CFP2 neCFP4 ivhoriyamu. Huwandu hweCFP2 ihafu yeCFP, uye CFP4 chikamu chimwe muzvina cheCFP. CFP8 ifomu yekurongedza yakanyatso kurongedzerwa 400G, uye saizi yayo yakaenzana neCFP2. Tsigira 25Gbps uye 50Gbps chiteshi mareti, uye ziva 400Gbps module chiyero kuburikidza ne16x25G kana 8×50 yemagetsi interface.
