Yiziphi izinhlelo zokusebenza zemaketheAma-amplifier optical e-SOA?
I-SOAi-amplifier ye-semiconductor opticaliyidivayisi ye-PN junction esebenzisa isakhiwo se-strain quantum well. I-external forward bias iholela ekuguqulweni kwenani lezinhlayiya, kanti ukukhanya kwangaphandle kuholela emisebeni evuselelwe, okuholela ekukhulisweni kwesignali ye-optical. Izinzuzo: Isekela isivinini esikhulu, i-bandwidth ephezulu, ukusetshenziswa kwamandla aphansi, inzuzo ephezulu, i-miniaturization, kanye nokuhlanganiswa okulula. Okubi: ukuguqulwa kwenzuzo ewela kanye nokusebenzisana okungeyona i-linear phakathi kweziteshi ezahlukene ze-wavelength, ukuzwela kwe-polarization, ukugcwala kwenzuzo. Uma kuqhathaniswa nama-amplifier e-EDFA optical (izikhulisi zefayibha ezifakwe i-erbium), ezinye izinkomba zamadivayisi ezentengiselwano zibuthakathaka kuneAma-amplifier optical e-EDFA, kodwa i-SOAama-amplifier opticalisenezici ezingenakushintshwa ama-amplifiers e-EDFA optical. Uma ingasekela ukukhulisa i-O-band (1260-1360), i-E-band (1360-1460), i-L-band (1460-1530), futhi inezici zezindleko eziphansi, usayizi omncane kanye nokuhlanganiswa okulula, enkathini entsha yengqalasizinda, ama-amplifiers e-SOA optical azoba kunethiwekhi yokufinyelela kanye nomkhawulo we-MAN, kanye nensimu yokuzwa i-optical fiber ukuthola izinhlelo zokusebenza ezinkulu.
Ukusetshenziswa kwemakethe kwe-SOA optical amplifier
Ngokuthuthuka kokusebenza kwe-SOA optical amplifier njengamandla okukhipha, ukutholakala kwesignali encane, ukuzwela kwe-gain polarization kanye ne-noise index, i-SOA amplifier izodlala indima ebaluleke kakhulu ekuxhumaneni kwenethiwekhi ye-all-optical kanye namanethiwekhi ezinzwa. Ngaphezu kwe-SOAama-amplifier opticalezingahlangabezana nokukhuliswa kwebhendi engu-1310 nm,Ama-amplifier e-SOAingathatha indawo yama-amplifier e-EDFA ngokuphelele kwezinye izinkambu zokukhulisa zesigaba esisodwa zebhendi engu-1550 nm.
1. Inethiwekhi yokudlulisa okubonakalayo yenkampani yenethiwekhi
Ngokwakhiwa kwenethiwekhi ye-5G, isidingo se-bandwidth siyakhula, futhi ukudluliselwa kwesivinini esiphezulu kwe-100G (4*25G CWDM4/LWDM4) kuyadingeka emaphethelweni enethiwekhi yokufinyelela kanye nenethiwekhi yendawo yedolobha, kanti ibanga lokudlulisela emaphethelweni okudluliselwa kwesifunda kanye nedolobha, inethiwekhi yokufinyelela kanye nenethiwekhi yendawo yedolobha ngokuvamile liyi-5km-40km. Esimweni sokudluliselwa phambili kwesiteshi sesisekelo se-5G, kwezinye iziteshi ezikude, i-optical modular.Idivayisi ye-SOAingasetshenziswa ukuthuthukisa i-optical power margin, kanye nokufeza ukuguqulwa kokukhanya okuphansi kwesilinganiso sesignali esingu-25G sesiteshi esiyisisekelo ebhendini engu-1310 nm kanye nebhendi engu-1550 nm. Ekusetshenzisweni kwenethiwekhi yenkampani, i-amplifier ye-SOA ingafakwa ku-ROSA noma i-TOSA ye-imodyuli ye-amplifier yokukhanya, noma idivayisi ye-SOA ezimele nomaImodyuli ye-SOA opticalingasetshenziswa ekukhuliseni.
2. Ukwandiswa kwe-spectral kokuqapha inethiwekhi
Njengamanje, ngentuthuko esheshayo yebhizinisi ledatha, isidingo sokuqapha ukusakazwa kwedatha emakethe sikhula kancane kancane, okuvame ukuba se-node yenethiwekhi eyinhloko yokuqapha i-spectral, isignali ivame ukuba buthaka, isidingo sokusebenzisa i-optical amplifier, kanye nebhizinisi le-100G linobude obungu-1310, lingakhuliswa kuphela yidivayisi ye-SOA. Lokhu futhi kuyindlela esetshenziswa kakhulu futhi evuthiwe yokukhulisa i-SOA okwamanje.
3. I-DCI yokuxhumana kwesikhungo sedatha
Ngokuthuthuka kwe-big data, isidingo sokuxhumana kwe-bandwidth ephezulu phakathi kwezikhungo zedatha siyakhula kancane kancane. Kumasevisi esivinini esikhulu, idivayisi ye-SOA ingasetshenziswa ekukhuliseni i-optical signal relay, kwandiswe i-link optical power margin kanye nokwelula ibanga lokudlulisela. Ama-amplifiers e-SOA angasetshenziswa kokubili ku-1310 band kanye ne-1550 band high-speed service optical signal amplification. Le makethe ngokuvamile isebenzisa ukuzimela.Ama-amplifier optical e-SOA semiconductor(amadivayisi afakwe ku-rack).
4. Ukusetshenziswa kokuzwa kwe-fiber optic okusatshalalisiwe kanye nohlelo lwe-LiDAR
Amamojula e-SOA optical anezici ezinhle kakhulu zokuphendula imvamisa kanye nesilinganiso esiphezulu sokushabalala, futhi angasetshenziswa njengezishintshi noma ama-modulators optical. Ngokuthuthuka okuqhubekayo kobuchwepheshe be-SOA, ama-modulators e-AOM angashintshwa ezimweni eziningi zokuzwa kwe-optical fiber ukuze kutholakale i-laser encane ye-pulse enesilinganiso esiphezulu sokushabalala.
Eminyakeni yamuva nje, ngentuthuko esheshayo yokushayela okuhlakaniphile kwethrafikhi okuzimele kanye nokuxhumanisa izimoto nomgwaqo, i-LiDAR isetshenziswe kabanzi kokubili emandleni aseceleni kwezimoto kanye nasemgwaqweni. Ngenxa yokunciphisa amandla kanye nokuzuza okukhulu kwe-Imojula ye-amplifier ye-SOA optical, ingasetshenziswa ku-LiDAR ukuthola i-laser encane yobubanzi bomugqa futhi ithuthukise amandla aphezulu okukhanya, ikakhulukazi i-chip ye-optical i-Lidar yesizukulwane esilandelayo sobuchwepheshe bendawo be-FMCW, okuyinkambu yokusetshenziswa ebanzi ye-SOA optical amplifier yesikhathi esizayo.
