Waa maxay codsiyada suuqa eeCod-weyneyaasha indhaha ee SOA?
SOAcod-weyneeye indho-indheynwaa aaladda isku xirka PN iyadoo la adeegsanayo qaab dhismeedka ceelka quantum-ka. Eexda hore u socotaa waxay keentaa qayb dadwayne rogan, iftiinka dibaddana wuxuu keenaa shucaac la kiciyay, taasoo keentay in kor loo qaado calaamadaha indhaha. Faa'iidooyinka: Waxay taageertaa xawaaraha sare, xawaaraha sare, isticmaalka tamarta hooseeya, faa'iidada sare, yaraynta, iyo isdhexgalka fudud. Khasaaraha: habaynta isdhaafsiga iyo isdhexgalka aan tooska ahayn ee u dhexeeya kanaalada mawjadaha dhererka ee kala duwan, dareenka polarization, helitaanka saturation. Marka la barbar dhigo cod-weyneyaasha indhaha ee EDFA (erbium-doped amplifiers fiber), tusmooyinka qaar ee aaladaha ganacsigu way ka daciifsan yihiinCod-weyneyaasha indhaha ee EDFAlaakiin SOAamplifiers indhahaweli waxay leeyihiin astaamo ay EDFA amplifiers indhaha ku beddeli karin. Haddii ay taageerto O-band (1260-1360), E-band (1360-1460), L-band (1460-1530) kordhinta, oo uu leeyahay sifooyinka qiimaha jaban, size yar iyo isdhexgalka fudud, in casriga cusub, amplifiers SOA indhaha waxay noqon doontaa in shabakada helitaanka iyo cidhifka codsiyada indhaha ee MAN, iyo sidoo kale si aad u hesho codsiyada indhaha.
Codsiga suuqa ee cod-weyneeye indhaha SOA
Iyada oo la wanaajinayo waxqabadka cod-weyneeye indhaha SOA sida awoodda indhaha ee soo-saarka, faa'iidada calaamadaha yar, helitaanka dareenka polarization iyo tusmada dhawaaqa, cod-weyneeye SOA wuxuu ka ciyaari doonaa door muhiim ah oo sii kordheysa ee dhammaan isgaarsiinta shabakadaha indhaha iyo shabakadaha dareemayaasha. Marka laga soo tago SOAamplifiers indhahakaas oo buuxin kara kordhinta 1310 nm band,Cod-weyneyaasha SOAwaxay si buuxda u bedeli karaan cod-weyneyayaasha EDFA qaybo ka mid ah hal-marxalad-weyneyn ah oo ah 1550 nm band.
1. Shabakadda gudbinta indhaha ee side
Dhismaha shabakada 5G, baahida bandwidth ayaa kor u kacda, iyo 100G (4 * 25G CWDM4 / LWDM4) gudbinta xawaaraha sare ayaa looga baahan yahay cirifka shabakada helitaanka iyo shabakadaha magaalada, iyo fogaanta gudbinta ee cidhifka gudbinta gobolka iyo magaalada, shabakada helitaanka iyo shabakada aagga magaalo-madaxda badanaa waa 5km-40km. Saldhigga saldhiga 5G ee hore u gudbinta, saldhigyada saldhiga qaarkood ee fog, qaab muuqaal ahQalabka SOAwaxaa loo isticmaali karaa si loo hagaajiyo margin awoodda indhaha, iyo in la ogaado isbedelka-iftiin yar ee heerka signal 25G ee saldhigga saldhigga ee 1310 nm band iyo 1550 nm band. Codsiga shabakada side, cod-weyneeye SOA waxa lagu dhex dari karaa ROSA ama TOSA eemodule-amplifier indhaha, ama aaladda SOA ee madaxa bannaan amaSOA moduleka indhahawaxaa loo isticmaali karaa xoojinta.
2. Kordhinta Spectral ee la socodka shabakada
Waqtigan xaadirka ah, horumarinta degdega ah ee ganacsiga xogta, baahida loo qabo kormeerka qulqulka xogta ee suuqa ayaa si tartiib tartiib ah u kordheysa, taas oo inta badan ku jirta xuddunta shabakadda ee kormeerka indhaha, calaamaduhu inta badan waa daciif, baahida loo qabo in la isticmaalo amplifier indhaha, iyo ganacsiga 100G wuxuu leeyahay wax badan oo ah 1310 mawjadaha, kaliya waxaa lagu kordhin karaa qalabka SOA. Tani sidoo kale waa codsiga loogu isticmaalka badan yahay uguna qaan-gaaray ee cod-weyneysiinta SOA hadda.
3. DCI ee isku xidhka xarunta xogta
Iyadoo horumarinta xogta weyn, baahida loo qabo isku xirka xawaaraha sare ee u dhexeeya xarumaha xogta ayaa si tartiib tartiib ah u kordhaya. Adeegyada xawaaraha sare leh, aaladda SOA waxa loo isticmaali karaa kor-u-qaadista is-dhaafsiga ishaarka, kordhinta xidhiidhka awoodda indhaha iyo fidinta fogaanta gudbinta. Cod-weyneyaasha SOA waxaa lagu dabaqi karaa labadaba 1310 band iyo 1550 band ee adeegga xawaaraha sare ee dhawaaqa dhawaaqa indhaha. Suuqani caadi ahaan waxa uu isticmaalaa kaligiisSOA semiconductor optical amplifiers(qalabka ku rakiban rack).
4. Codsiga dareenka fibre optic ee la qaybiyey iyo nidaamka LiDAR
Qaybaha indhaha ee SOA waxay leeyihiin sifooyin jawaab celin heersare ah oo heersare ah iyo saamiga baabi'inta sare, waxaana loo isticmaali karaa furayaasha indhaha ama modulators. Horumarka joogtada ah ee tignoolajiyada SOA, modulators AOM waxaa lagu bedeli karaa inta badan xaaladaha dareenka fiber indhaha si loo helo laser garaaca cidhiidhi ah oo leh saamiga baabi'inta sare.
Sanadihii la soo dhaafay, iyada oo si xawli ah u kobcay taraafikada iskeed u madax bannaan wadista iyo isku-dubbaridka gaadiidka, LiDAR waxaa si weyn loogu isticmaalay gaadiidka-dhinaca iyo ciidamada waddooyinka. Sababtoo ah miniaturization iyo faa'iidada sare eeQalabka cod-weyneeye ee SOA, waxaa lagu dabaqi karaa gudaha LiDAR si loo helo laydhka cidhiidhiga ah ee cidhiidhiga ah iyo hagaajinta awooda sare ee indhaha, gaar ahaan chip-ka indhaha ee Lidar jiilka soo socda ee tignoolajiyada FMCW maxalliga ah, kaas oo ah goob codsi oo ballaadhan oo mustaqbalka SOA optical amplifier.
