Ndezvipi zvinoshandiswa pamusikaMa amplifiers eSOA optical?

SOAamplifier ye optical ye semiconductormudziyo wePN junction unoshandisa chimiro che strain quantum well. Kukanganisa kwekunze kwemberi kunoita kuti particle population inversion iite, uye chiedza chekunze chinotungamira ku radiation inosimudzirwa, zvichikonzera optical signal amplification. Zvakanakira: Inotsigira kumhanya kwakanyanya, bandwidth yakakwira, kushandiswa kwesimba shoma, gain yakakwira, miniaturization, uye nyore kubatanidzwa. Zvakashata: cross-gain modulation uye nonlinear interaction pakati pema wavelength channels akasiyana, polarization sensitivity, gain saturation. Zvichienzaniswa neEDFA optical amplifiers (ma amplifiers efayibha ane erbium), mamwe ma indekisi ezvishandiso zvekutengeserana haana kusimba paneEDFA optical amplifiers, asi SOAma amplifiers emazisoZvichiri nemaitiro asingatsiviwe nema EDFA optical amplifiers. Kana ichikwanisa kutsigira O-band (1260-1360), E-band (1360-1460), L-band (1460-1530) amplification, uye iine hunhu hwemutengo wakaderera, hukuru hudiki uye nyore kubatanidzwa, munguva itsva yezvivakwa, ma SOA optical amplifiers achave ari mu access network uye kumucheto kweMAN, pamwe ne optical fiber sensing field kuti iwane maapplication makuru.

Kushandiswa kweSOA optical amplifier pamusika

Nekuvandudzika kwekushanda kweSOA optical amplifier senge simba re optical rinobuda, small signal gain, gain polarization sensitivity uye noise index, SOA amplifier ichaita basa rakakosha mukukurukurirana kwenetwork ye optical uye masensa network. Pamusoro peSOA, SOA ichaita basa rakakosha mukukurukurirana kwe network ye optical uye masensa network.ma amplifiers emazisoinogona kusangana nekuwedzera kwebhendi re1310 nm,Ma amplifiers eSOAinogona kutsiva zvachose ma amplifiers eEDFA mune mamwe ma field ekuwedzera echikamu chimwe chete che 1550 nm band.

1. Network yekutakura optical transmission

Nekuvakwa kwenetwork ye5G, kudiwa kwebandwidth kunowedzera, uye 100G (4*25G CWDM4/LWDM4) transmission inomhanyisa inodiwa pamucheto wenetwork yekusvika uye network yenzvimbo yemaguta, uye daro rekutumira pamucheto wetransmission yedunhu neguta, network yekusvika uye network yenzvimbo yemaguta rinowanzova 5km-40km. Muchiitiko chetransmission yechiteshi che5G base, mune dzimwe nzvimbo dziri kure, optical modular.Mudziyo weSOAinogona kushandiswa kuvandudza margin yesimba re optical, uye kuona shanduko yechiedza chidiki ye25G signal rate yebase station mu1310 nm band uye 1550 nm band. Mukushandiswa kwecarrier network, SOA amplifier inogona kubatanidzwa muROSA kana TOSA yemodule ye optical amplifier, kana mudziyo weSOA wakazvimiririra kanaSOA optical moduleinogona kushandiswa kuwedzera simba.

2. Kuwedzerwa kwekutarisa network kuburikidza ne spectral

Parizvino, nekukura kuri kuita bhizinesi redata nekukurumidza, kudiwa kwekutarisa kutenderera kwedata mumusika kuri kuwedzera zvishoma nezvishoma, izvo zvinowanzo kuve mu "core network node" yekutarisa spectral, chiratidzo chinowanzova chisina simba, kudiwa kwekushandisa optical amplifier, uye 100G business ine wavelength yakawanda ye1310, inogona kungowedzerwa neSOA device chete. Uku ndiko kushandiswa kwakanyanya uye kwakakura kweSOA amplification pari zvino.

3. DCI yekubatanidza nzvimbo yedata

Nekuvandudzwa kwedata guru, kudiwa kwekubatana kwebandwidth yakakura pakati penzvimbo dzedata kuri kuwedzera zvishoma nezvishoma. Kune masevhisi ekumhanya-mhanya, mudziyo weSOA unogona kushandiswa pakuwedzera masaini emagetsi, kuwedzera simba remagetsi rekubatanidza uye kuwedzera daro rekutumira. Maamplifier eSOA anogona kushandiswa kune ese ari maviri 1310 band uye 1550 band high-speed service optical signal amplification. Musika uyu unowanzo shandisa wega.SOA semiconductor optical amplifiers(midziyo yakaiswa parack).

4. Kushandiswa kwe distributed fiber optic sensing uye LiDAR system

Mamodule eSOA optical ane hunhu hwakanaka hwemhinduro yema frequency uye chiyero chekupera kwemhepo chakakwira, uye anogona kushandiswa sema optical switch kana ma modulators. Nekuvandudzwa kuri kuramba kuchiitwa kwetekinoroji yeSOA, ma AOM modulators anogona kutsiviwa mune akawanda mamiriro e optical fiber sensing kuti awane narrow pulse laser ine chiyero chekupera kwemhepo chakakwira.

Mumakore achangopfuura, nekukura nekukurumidza kwekutyaira kwemotokari nemotokari zvakananga uye kubatana kwemotokari nemugwagwa, LiDAR yave ichishandiswa zvakanyanya mumagetsi ese ari maviri emotokari nepadivi pemugwagwa. Nekuda kwekushandiswa kwayo zvishoma uye kuwedzera kukuru kweSOA optical amplifier module, inogona kushandiswa muLiDAR kuwana laser yakamanikana uye kuvandudza simba remagetsi rakawanda, kunyanya chip yemagetsi yeLidar yechizvarwa chinotevera chetekinoroji yeFMCW yemuno, inova nzvimbo yakakura yekushandisa yeSOA optical amplifier yeramangwana.
