Intshayelelo esisiseko yemodyuli yokubona

Imodyuli ye-optical yenziwe ngezixhobo ze-optoelectronic, iisekethe ezisebenzayo kunye ne-optical interfaces. Izixhobo ze-optoelectronic ziquka iinxalenye ezimbini: ukuhambisa kunye nokwamkela. Ngamafutshane, umsebenzi wemodyuli ye-optical kukuguqula umqondiso wombane kwi-signal optical ekupheleni kokuthumela. Emva kokuba isignali ye-optical idluliselwe nge-fiber optical, isiphelo sokufumana siguqula isignali ye-optical kwisignali yombane.

Inxalenye yothumelo yile: igalelo lombane umqondiso womlinganiselo othile wesuntswana licutshungulwa yi-chip yangaphakathi ye-drive, kwaye emva koko iqhube i-semiconductor laser (LD) okanye i-diode yokukhanya ekhuphayo (i-LED) ukuze ikhuphe i-modulated optical signal yezinga elihambelanayo. I-optical power yangaphakathi yolawulo lwesekethe ngokuzenzekelayo ixhotyiswe ukugcina i-output optical signal power power ezinzileyo.

Inxalenye efunyenweyo yile: imodyuli ye-optical input module kunye ne-bit rate ethile iguqulwa ibe yisignali yombane yi-optical discovery diode, kunye nesignali yombane kunye nesantya se-bit esihambelanayo siphuma emva kwe-preamplifier.

-Ingqiqo esisiseko yemodyuli yokubona-

Imodyuli yePort-optical ligama eliqhelekileyo leendidi ezahlukeneyo zemodyuli, ibhekisa ngokubanzi kwimodyuli edibeneyo yetransceiver edibeneyo.

-Ukusebenza kwemodyuli yokubona-

Umsebenzi wayo kukuqonda nje uguqulo phakathi kwemiqondiso ye-optical kunye nemiqondiso yombane.

-Ulwakhiwo lwemodyuli yokubona-

Imodyuli ye-optical idla ngokuqulunqwa yi-transmitter optical, i-optical receiver, isiphaluka esisebenzayo kunye ne-optical (electrical) interface.

Kwi-transmitter, i-chip yomqhubi isebenzisa umqondiso wokuqala wombane, kwaye emva koko iqhube i-laser semiconductor (LD) okanye i-light emitting diode (LED) ukukhupha isignali ye-optical modulated.

Izibuko likwisiphelo sokufumana. Emva kokuba isignali ye-optical ingene, iguqulwa ibe ngumqondiso wombane yi-optical discovery diode, emva koko ikhuphe umqondiso wombane nge-preamplifier.

-Ukuhlelwa kwendlela yokubona-

-Uphuhliso lwembali yemowudi yamehlo-

-Intshayelelo yokupakishwa kwemodyuli ye-optical-

Kukho uluhlu olubanzi lwemigangatho yokupakisha yeemodyuli zamehlo, ngakumbi ngenxa yokuba:

》Isantya sophuhliso lobuchwephesha bonxibelelwano lwefiber optical sikhawuleza kakhulu. Isantya semodyuli ye-optical siyanda, kwaye ivolumu nayo iyancipha, ukuze yonke iminyaka embalwa, iilebhile zokupakisha ezintsha ziya kukhutshwa.

ichanekile Kwakhona kunzima ukuhambelana phakathi kwemigangatho yokupakisha emitsha nendala.

》Iimeko zosetyenziso lweemodyuli ezibonakalayo zahlukene. Ukuhanjiswa komgama ohlukeneyo, iimfuno ze-bandwidth, kunye neendawo zokusetyenziswa, ezihambelana neentlobo ezahlukeneyo zefiber optical ezisetyenzisiweyo, iimodyuli ze-optical nazo zihluke.

IPort GBIC

I-GBIC yi-Giga Bitrate Interface Converter.

Ngaphambi kowama-2000, i-GBIC yayiyeyona nto idumileyo yokupakishwa kwemodyuli ye-optical kunye neyona ndlela isetyenziswa kakhulu kwimodyuli yegigabit.

Izibuko le-SFP

Ngenxa yobukhulu obukhulu be-GBIC, i-SFP yavela kamva kwaye yaqala ukuthatha indawo ye-GBIC.

I-SFP, igama elipheleleyo leFom-Factor ePluggable encinci, yimodyuli encinci eguqukayo eshushu. Ubungakanani bayo obuncinci buhambelana nokupakishwa kwe-GBIC. Ubungakanani be-SFP buncinci kunesiqingatha semodyuli ye-GBIC, kwaye ngaphezu kokuphindwe kabini inani lamachweba lingaqwalaselwa kwiqela elinye. Ngokumalunga nomsebenzi, kukho umahluko omncinci phakathi kwezi zimbini, kwaye zombini zixhasa iplagi eshushu. I-bandwidth ephezulu exhaswa yi-SFP yi-4Gbps

XFP yomlomo

I-XFP yi-10-Gigabit Small Form-Factor Pluggable, enokuqondwa ngokujonga nje. Yi-10-Gigabit SFP.

I-XFP ithatha imodyuli ye-serial ye-serial ye-speed-speed single-channel exhunywe yi-XFI (i-10Gb i-serial interface), enokuthi ithathe indawo ye-Xenpak kunye ne-derivatives yayo.

Izibuko SFP+

I-SFP +, njenge-XFP, yimodyuli ye-10G ye-optical.

Ubungakanani be-SFP + bufana ne-SFP. I-compact ngaphezu kwe-XFP (incitshiswe malunga ne-30%), kwaye ukusetyenziswa kwayo kwamandla kuncinci (kuncitshiswe yiminye imisebenzi yokulawula umqondiso).

O SFP28

I-SFP enezinga le-25Gbps ikakhulu ngenxa yokuba i-40G kunye ne-100G iimodyuli ze-optical zazibiza kakhulu ngelo xesha, ngoko ke le nkqubo yenguqu ye-compromise yenziwa.

QSFP/QSFP+/QSFP28/QSFP28-DD

I-Quad Small Form-Factor Pluggable, i-interface ye-SFP ene-channel ezine. Uninzi lweetekhnoloji eziphambili ezivuthiweyo kwi-XFP zisetyenzisiwe kolu yilo. I-QSFP inokwahlulwa ibe yi-4 ngokwesantya × 10G QSFP +, 4 × 25G QSFP28, 8 × 25G QSFP28-DD imodyuli ebonakalayo, njl.

Thatha i-QSFP28 njengomzekelo, esebenzayo kwi-port ye-4 × 25GE yokufikelela. I-QSFP28 ingasetyenziselwa ukuphucula ukusuka kwi-25G ukuya kwi-100G ngaphandle kwe-40G, yenza lula kakhulu ubunzima bekhebula kunye nokunciphisa iindleko.

QSFP/QSFP+/QSFP28/QSFP28-DD

I-QSFP-DD, eyasungulwa ngo-Matshi 2016, ibhekisela kwi-"Double Density". Yongeza umqolo wamajelo kwii-4 iziteshi ze-QSFP kwaye uzitshintshe zibe yi-8 channels.

Inokuhambelana nenkqubo ye-QSFP. Imodyuli yoqobo ye-QSFP28 isenokusetyenziswa, faka nje enye imodyuli. Inani leminwe yegolide ye-OSFP-DD iphindwe kabini kune-QSFP28.

I-QSFP-DD nganye ithatha i-25Gbps NRZ okanye i-50Gbps i-PAM4 ifomathi yesignali. NgePAM4, inokuxhasa ukuya kuthi ga kwi-400Gbps.

OSFP

I-OSFP, i-Octal Small Form Factor Pluggable, "O" imele "i-octal", eyasungulwa ngokusemthethweni ngoNovemba ka-2016.

Yenzelwe ukusebenzisa iziteshi zombane ze-8 ukuqonda i-400GbE (8 * 56GbE, kodwa isignali ye-56GbE yenziwe nge-laser ye-25G DML phantsi kwe-modulation ye-PAM4), kwaye ubungakanani bayo bukhulu kancinci kune-QSFP-DD. I-injini ye-optical kunye ne-transceiver ene-wattage ephezulu inomsebenzi ongcono kancinane wokulahla ubushushu.

CFP/CFP2/CFP4/CFP8

I-Centum gigabits Form I-Pluggable, i-dense wavelength division optical communication module. Isantya sothumelo sinokufikelela kwi-100-400Gbpso

I-CFP yenzelwe ngokusekelwe kwi-interface ye-SFP, kunye nobukhulu obukhulu kunye nokuxhasa ukuhanjiswa kwedatha ye-100Gbps. I-CFP inokuxhasa uphawu olulodwa lwe-100G kunye nesinye okanye ngaphezulu kweempawu ze-40G.

Umahluko phakathi kweCFP, CFP2 kunye neCFP4 ngumthamo. Umthamo weCFP2 usisiqingatha seCFP, yaye iCFP4 yikota yalowo weCFP. I-CFP8 ifom yokupakisha ecetywayo ngokukodwa kwi-400G, kwaye ubukhulu bayo bulingana neCFP2. Inkxaso ye-25Gbps kunye ne-50Gbps ye-channel rates, kwaye uqaphele izinga lemodyuli ye-400Gbps nge-16x25G okanye i-8 × 50 ujongano lombane.
