Kodi ma amplifiers a SOA semiconductor optical amplifiers amagwiritsidwa ntchito bwanji pamsika?

Kodi ntchito zamsika ndi ziti?Ma amplifiers a SOA optical?

SOAsemiconductor kuwala amplifierndi chipangizo cholumikizira cha PN chomwe chimagwiritsa ntchito kapangidwe ka chitsime cha quantum. Kusankha kwakunja kwa kutsogolo kumapangitsa kuti tinthu tisinthe, ndipo kuwala kwakunja kumabweretsa kuwala kolimbikitsidwa, zomwe zimapangitsa kuti chizindikiro cha optical chiwonjezere mphamvu. Ubwino: Kumathandizira kuthamanga kwambiri, bandwidth yayikulu, kugwiritsa ntchito mphamvu zochepa, kupeza mphamvu zambiri, miniaturization, komanso kuphatikiza mosavuta. Zoyipa: kusintha kwa cross-gain ndi kuyanjana kosagwirizana pakati pa njira zosiyanasiyana za wavelength, kukhudzidwa kwa polarization, kuchuluka kwa mphamvu. Poyerekeza ndi ma amplifiers a EDFA optical (zokulitsa ulusi zopangidwa ndi erbium), zizindikiro zina za zipangizo zamalonda ndizofooka kuposaMa amplifiers a EDFA optical, koma SOAma amplifiers a kuwalaakadali ndi makhalidwe omwe ma amplifiers a EDFA optical sangathe kuwasintha. Ngati angathe kuthandizira kukulitsa kwa O-band (1260-1360), E-band (1360-1460), L-band (1460-1530), ndipo ali ndi makhalidwe otsika mtengo, ang'onoang'ono komanso osavuta kuphatikiza, munthawi yatsopano yomanga, ma amplifiers a SOA optical adzakhala mu netiweki yofikira ndi m'mphepete mwa MAN, komanso malo owonera ulusi wa optical kuti apeze ntchito zazikulu.

Kugwiritsa ntchito kwa SOA optical amplifier pamsika

Ndi kusintha kwa magwiridwe antchito a SOA optical amplifier monga mphamvu yotulutsa, kuchuluka kwa ma signal ochepa, kukhudzidwa kwa polarization ndi noise index, SOA amplifier idzakhala ndi gawo lofunika kwambiri pakulankhulana kwa netiweki yonse komanso ma sensor network. Kupatula SOA, SOA idzakhala ndi mphamvu yotulutsa ma optical amplifier, yomwe idzakhala yofunikira kwambiri pakulankhulana kwa ma netiweki onse komanso ma sensor network.ma amplifiers a kuwalazomwe zingakwaniritse kukulitsa kwa gulu la 1310 nm,Ma amplifiers a SOAakhoza kusintha ma amplifiers a EDFA m'magawo ena okulitsa a single-stege a 1550 nm band.

1. Netiweki yotumizira kuwala yonyamula

Pogwiritsa ntchito netiweki ya 5G, kufunika kwa bandwidth kumawonjezeka, ndipo kutumiza kwa liwiro la 100G (4 * 25G CWDM4 / LWDM4) kumafunika m'mphepete mwa netiweki yolowera ndi netiweki ya m'mizinda, ndipo mtunda wotumizira uthenga m'mphepete mwa kutumiza uthenga m'mizinda ndi m'matauni, netiweki yolowera ndi netiweki ya m'mizinda nthawi zambiri umakhala 5km-40km. Mu 5G base station forward transmission, m'malo ena oyambira omwe ali kutali, optical modular.Chipangizo cha SOAingagwiritsidwe ntchito kukweza malire a mphamvu ya kuwala, ndikuzindikira kusintha kochepa kwa liwiro la chizindikiro cha 25G cha siteshoni yoyambira mu gulu la 1310 nm ndi gulu la 1550 nm. Pogwiritsa ntchito netiweki yonyamula, amplifier ya SOA ikhoza kuphatikizidwa mu ROSA kapena TOSA yagawo lokulitsa kuwala, kapena chipangizo chodziyimira pachokha cha SOA kapenaSOA optical moduleingagwiritsidwe ntchito powonjezera mphamvu.

2. Kukulitsa kwa spectral kwa kuwunika kwa netiweki

Pakadali pano, chifukwa cha kukula kwachangu kwa bizinesi ya data, kufunikira kwa kuwunika kutsata deta pamsika kukuwonjezeka pang'onopang'ono, komwe nthawi zambiri kumakhala mu netiweki yayikulu yowunikira ma spectral, chizindikiro nthawi zambiri chimakhala chofooka, kufunikira kogwiritsa ntchito amplifier ya optical, ndipo bizinesi ya 100G ili ndi mafunde ambiri a 1310, ndipo imatha kukulitsidwa ndi chipangizo cha SOA chokha. Iyi ndi njira yogwiritsidwa ntchito kwambiri komanso yokhwima yowonjezerera SOA pakadali pano.

3. DCI yolumikizira malo osungira deta

Ndi chitukuko cha big data, kufunikira kwa kulumikizana kwa bandwidth yayikulu pakati pa malo osungira deta kukukulirakulira pang'onopang'ono. Pa mautumiki othamanga kwambiri, chipangizo cha SOA chingagwiritsidwe ntchito pokulitsa chizindikiro cha optical, kukulitsa malire a mphamvu ya optical link ndikukulitsa mtunda wotumizira. Ma amplifiers a SOA angagwiritsidwe ntchito pa 1310 band ndi 1550 band high-speed service optical signal amplification. Msika uwu nthawi zambiri umagwiritsa ntchito wokhawokha.Ma amplifiers a SOA semiconductor optical(zipangizo zomangidwira pa raki).

4. Kugwiritsa ntchito njira yodziwira kuwala kwa fiber optic ndi LiDAR

Ma module a SOA optical ali ndi makhalidwe abwino kwambiri oyankha pafupipafupi komanso chiŵerengero chachikulu cha kuzimiririka, ndipo angagwiritsidwe ntchito ngati ma switch kapena ma modulators a optical. Ndi kusintha kosalekeza kwa ukadaulo wa SOA, ma modulators a AOM amatha kusinthidwa m'njira zambiri za optical fiber sensor kuti apeze laser yopapatiza yokhala ndi chiŵerengero chachikulu cha kuzimiririka.

M'zaka zaposachedwa, chifukwa cha kupita patsogolo mwachangu kwa kuyendetsa magalimoto mwanzeru komanso kulumikizana kwa magalimoto ndi msewu, LiDAR yakhala ikugwiritsidwa ntchito kwambiri m'magulu onse awiri, m'mbali mwa magalimoto komanso m'mbali mwa msewu. Chifukwa cha kuchepa kwa mphamvu zamagetsi komanso kuwonjezeka kwakukulu kwa mphamvu zamagetsi.Gawo la SOA optical amplifier, ingagwiritsidwe ntchito mu LiDAR kuti ipeze laser yopapatiza komanso kukweza mphamvu yamagetsi yowala, makamaka chipangizo chowunikira cha Lidar cha m'badwo wotsatira wa ukadaulo wa FMCW wakomweko, chomwe ndi gawo lalikulu logwiritsira ntchito mtsogolo la SOA optical amplifier.
