Zithini iiModyuli zeOptical? Inkcazo kunye nomsebenzi oyintloko

I-An imodyuli yokujonga (i-transceiver yokujonga) sisixhobo se-elektroniki-optical esitshixwayo esiguqula imiqondiso yombane ibe yimiqondiso ye-optical ukuze idluliselwe ngefayibha ye-optical, emva koko iguqulela imiqondiso ye-optical ibuyele kwimiqondiso yombane. Idla ngokubizwa ngokuba "yintliziyo yonxibelelwano lwe-optical," idibanisa amakhulu ee-micro-components—kuquka ii-laser, ii-photodiodes, ii-driver chips, ii-optical lens, kunye neesekethe zokucubungula imiqondiso—kwiphakheji encinci nesemgangathweni.
Ixabiso eliphambili leemodyuli ze-optical lisekusombululeni imida esisiseko yokudluliselwa kombane okusekelwe kubhedu: ukuncitshiswa kwesignali, ukuphazamiseka kwe-electromagnetic (EMI), kunye neengxaki ze-bandwidthNgelixa iintambo zobhedu zisokola umgama ongaphaya kweemitha ezili-100 kunye namanani aphezulu edatha, iimodyuli ze-optical zisebenzisa iingenelo ezikhethekileyo ze-fiber optics—ilahleko ephantsi (0.2dB/km), i-bandwidth ephezulu kakhulu (>50THz), kunye nokungakhuseleki kwi-EMI—ukudlulisa idatha kwiikhilomitha ezingamakhulu ngesantya esifikelela kwi-terabits ngomzuzwana (ii-Tbps).

Izinto eziphambili zeeModyuli zoKubona

Ukuze uqonde indlela ezisebenza ngayo, kubalulekile ukuhlalutya ezi zixhobo ziphambili:
  1. I-Transmitter Optical Sub-Assembly (TOSA): Iguqula imiqondiso yombane ibe yimiqondiso ye-optical isebenzisa ii-laser (DFB, EML, okanye i-VCSEL).
  2. I-Receiver Optical Sub-Assembly (ROSA): Iguqula imiqondiso ye-optical engenayo ibuyele kwimiqondiso yombane nge-photodiodes (PIN/APD).
  3. Iitships zoMqhubi kunye neDSP: Yandisa imiqondiso yombane, uhlengahlengise imveliso yelaser, kwaye uqhube idatha efunyenweyo ukuze kulungiswe iimpazamo.
  4. Ujongano olubonakalayo: Iqhagamshela kwiintambo zefayibha (izihlanganisi ze-LC, SC, MPO) ukuze zidluliswe ngesignali.
  5. Ulawulo kunye nokuBek' esweni iiSekethe: Ivumela ukulandelelwa kobushushu, i-voltage, kunye namandla okukhanya (DDM/DDMI) ngexesha langempela ukuze kuthembeke.

Indlela Ezisebenza Ngayo Iimodyuli Zokukhanya: Umjikelo Wokuguqulwa "Kombane-Optical-Electrical"

Ukusebenza kweemodyuli ze-optical kulandela indlela elula kodwa entsonkothileyo I-EOE (uMbane-optical-Electrical) umsebenzi wokusebenza, yahlulwe yangamanqanaba amathathu aphambili:

1. Uthumelo (Ukuguqulwa kwe-EO)

Imiqondiso yedatha yombane (0s kunye ne-1s) evela kwiiseva, iiswitshi, okanye ii-routers zithunyelwa kwi-chip yomqhubi we-optical module. I-chip iguqula i-laser ye-semiconductor (umz., i-DFB yefayibha yemowudi enye, i-VCSEL yefayibha yemowudi ezininzi) ukuze ikhuphe ii-pulses zokukhanya ezihambelana nemiqondiso yombane. Ezi pulses zokukhanya emva koko zifakwa kwi-fiber ye-optical ukuze zidluliselwe.

2. Ukuhanjiswa kweFayibha

Isignali ye-optical ihamba kwi-fiber core ngelahleko encinci kwaye akukho EMI. I-single-mode fiber (SMF) ixhasa uthumelo lomgama omde (ukuya kuthi ga kwi-120km kwi-telecom), ngelixa i-multi-mode fiber (MMF) isetyenziselwa uqhagamshelo lweziko ledatha elikufutshane (100m-2km).

3. Ukwamkelwa (Ukuguqulwa kwe-OE)

Kwindawo eya kuyo, i-ROSA yemodyuli ye-optical ifumana iipulses zokukhanya. I-photodiode iguqula isignali ye-optical ibuyele kwisignali yombane, eya kuthi emva koko ikhuliswe, icocwe, kwaye icutshungulwe yi-chip ye-DSP ukuze ifumane idatha yokuqala. Isignali yombane ekugqibeleni ithunyelwa kwisixhobo esifumanayo (iseva, i-router, njl.njl.).
Olu guqulelo lwe-EOE olungenamthungo lwenza idatha ikwazi ukuhamba isantya sokukhanya ngokusebenzisa iinethiwekhi zefayibha, nto leyo eyenza iimodyuli ze-optical zibe yeyona nto ibalulekileyo kunxibelelwano olukhawulezayo.
