Zithini izicelo zemarikeIi-amplifier ze-SOA ezibonakalayo?
I-SOAi-amplifier ye-optical ye-semiconductorsisixhobo se-PN junction esisebenzisa isakhiwo se-strain quantum well. I-external forward bias ibangela ukuguqulwa kwenani lee-particle population, kwaye ukukhanya kwangaphandle kukhokelela kwi-radiation evuselelweyo, okubangela ukwandiswa kwesignali ye-optical. Iingenelo: Ixhasa isantya esiphezulu, i-bandwidth ephezulu, ukusetyenziswa kwamandla aphantsi, i-gain ephezulu, i-miniaturization, kunye nokuhlanganiswa okulula. Iingxaki: i-cross-gain modulation kunye nokusebenzisana okungeyo-linear phakathi kweendlela ezahlukeneyo ze-wavelength, uvakalelo lwe-polarization, i-gain saturation. Xa kuthelekiswa ne-EDFA optical amplifiers (izikhulisi zefayibha ezine-erbium), ezinye ii-index zezixhobo zorhwebo zibuthathaka kuneIi-amplifier ze-EDFA ezibonakalayokodwa i-SOAizixhobo zokukhulisa ukukhanyaiseneempawu ezingenakuthathelwa indawo zi-EDFA optical amplifier. Ukuba inokuxhasa i-O-band (1260-1360), i-E-band (1360-1460), i-L-band (1460-1530), kwaye ineempawu zexabiso eliphantsi, ubungakanani obuncinci kunye nokudibanisa okulula, kwixesha elitsha leziseko zophuhliso, ii-SOA optical amplifier ziya kuba kwinethiwekhi yokufikelela kunye nomda we-MAN, kunye nentsimi yokubona i-optical fiber ukuze ifumane usetyenziso olukhulu.
Ukusetyenziswa kwemarike ye-SOA optical amplifier
Ngokuphuculwa kokusebenza kwe-SOA optical amplifier efana namandla e-output optical, i-small signal gain, i-gain polarization sensitivity kunye ne-noise index, i-SOA amplifier iya kudlala indima ebaluleke ngakumbi kunxibelelwano lwenethiwekhi ye-all-optical kunye neenethiwekhi ze-sensor. Ukongeza kwi-SOAizixhobo zokukhulisa ukukhanyaezinokuhlangabezana nokwandiswa kwebhendi ye-1310 nm,Ii-amplifiers ze-SOAingathatha indawo ngokupheleleyo yee-amplifiers ze-EDFA kwezinye iindawo zokukhulisa ezinesigaba esinye zebhendi ye-1550 nm.
1. Inethiwekhi yokudlulisa i-optical yenkampani
Ngokwakhiwa kwenethiwekhi ye-5G, imfuno ye-bandwidth iyanda, kwaye i-100G (4 * 25G CWDM4 / LWDM4) transmission ekhawulezayo iyadingeka kumda wenethiwekhi yokufikelela kunye nenethiwekhi yendawo yedolophu, kwaye umgama wokudlulisela kumda wenethiwekhi yesithili neyedolophu, inethiwekhi yokufikelela kunye nenethiwekhi yendawo yedolophu idla ngokuba yi-5km-40km. Kwimeko yokudlulisela phambili kwisikhululo sesiseko se-5G, kwezinye izikhululo zesiseko ezikude, i-optical modular.Isixhobo se-SOAingasetyenziselwa ukuphucula umda wamandla okukhanya, kunye nokufezekisa utshintsho oluphantsi lokukhanya kwesantya sesiginali se-25G sesikhululo sesiseko kwibhendi ye-1310 nm kunye nebhendi ye-1550 nm. Ekusetyenzisweni kwenethiwekhi yomphathi, i-amplifier ye-SOA ingadibaniswa ne-ROSA okanye i-TOSA yeimodyuli ye-amplifier yokukhanya, okanye isixhobo esizimeleyo se-SOA okanyeImodyuli ye-SOA opticalingasetyenziselwa ukwandisa.
2. Ukwandiswa kwe-spectral yokubeka esweni inethiwekhi
Okwangoku, ngophuhliso olukhawulezayo lweshishini ledatha, imfuno yokujonga ukusasazwa kwedatha kwimarike iyanda kancinci kancinci, nto leyo edla ngokuba kwi-node yenethiwekhi ephambili yokujonga i-spectral, isignali idla ngokuba buthathaka, imfuneko yokusebenzisa i-optical amplifier, kwaye ishishini le-100G linobude obuyi-1310 ubude, lunokwandiswa kuphela sisixhobo se-SOA. Esi sikwasetyenziswa kakhulu kwaye sivuthiweyo sokukhulisa i-SOA okwangoku.
3. I-DCI yokunxibelelana kweziko ledatha
Ngophuhliso lwe-big data, imfuno yokunxibelelana kwe-bandwidth ephezulu phakathi kwamaziko edatha iyanda kancinci kancinci. Kwiinkonzo zesantya esiphezulu, isixhobo se-SOA singasetyenziselwa ukukhulisa i-optical signal relay, ukwandisa umda wamandla okukhanya kwekhonkco kunye nokwandisa umgama wokudlulisela. Ii-amplifiers ze-SOA zingasetyenziswa kuzo zombini i-1310 band kunye ne-1550 band high-speed service optical signal amplification. Le marike idla ngokusebenzisa ukuzimela.Ii-amplifier ezibonakalayo ze-SOA semiconductor(izixhobo ezifakelwe kwi-rack).
4. Ukusetyenziswa kwe-distributed fiber optic sensing kunye nenkqubo ye-LiDAR
Iimodyuli ze-SOA optical zineempawu ezibalaseleyo zokuphendula rhoqo kunye nomlinganiselo ophezulu wokuphela, kwaye zingasetyenziswa njengeeswitshi ze-optical okanye ii-modulators. Ngokuphuculwa okuqhubekayo kwetekhnoloji ye-SOA, ii-modulators ze-AOM zinokutshintshwa kwiimeko ezininzi ze-optical fiber sensing ukuze kufunyanwe i-laser ye-pulse encinci enomlinganiselo ophezulu wokuphela.
Kwiminyaka yakutshanje, ngophuhliso olukhawulezayo lokuqhuba ngokuzimela kwezithuthi kunye nokulungelelaniswa kwezithuthi neendlela, i-LiDAR isetyenziswa kakhulu kwiimoto ezisecaleni kwendlela kunye nezithuthi ezisecaleni kwendlela. Ngenxa yokunciphisa amandla kunye nokwanda okukhulu kwezithuthi.Imodyuli ye-amplifier ye-SOA optical, ingasetyenziswa kwiLiDAR ukufumana i-laser yobubanzi obuncinci kunye nokuphucula amandla aphezulu okukhanya, ingakumbi i-chip ye-optical Lidar yesizukulwana esilandelayo sobuchwepheshe be-FMCW basekhaya, eliyindawo ebanzi yokusetyenziswa kwe-SOA optical amplifier yexesha elizayo.
