Zowonjezeredwasemiconductor kuwala amplifier

Chowonjezera cha semiconductor optical amplifier ndi mtundu wosinthidwa wa chowonjezera cha semiconductor optical (Chokulitsa kuwala cha SOANdi amplifier yomwe imagwiritsa ntchito ma semiconductors kuti ipereke njira yopezera mphamvu. Kapangidwe kake ndi kofanana ndi ka Fabry-Pero laser diode, koma nthawi zambiri nkhope yomaliza imakhala ndi filimu yotsutsana ndi kuwunikira. Kapangidwe katsopano kamakhala ndi mafilimu otsutsana ndi kuwunikira komanso ma waveguides opendekera ndi madera a zenera, zomwe zimatha kuchepetsa kuwunikira kwa nkhope yomaliza kufika pansi pa 0.001%. Ma amplifier optical optimated optimated optimated ndi othandiza kwambiri pokweza zizindikiro (zowala), chifukwa pali chiopsezo chachikulu cha kutayika kwa chizindikiro panthawi yotumiza mtunda wautali. Popeza chizindikiro chowala chimakulitsidwa mwachindunji, njira yachikhalidwe yosinthira kukhala chizindikiro chamagetsi isanayambe imakhala yosafunikira. Chifukwa chake, kugwiritsa ntchitoSOAZimathandizira kwambiri kuyendetsa bwino ma transmission. Ukadaulo uwu nthawi zambiri umagwiritsidwa ntchito pogawa mphamvu ndi kubweza ndalama zomwe zatayika mu ma network a WDM.

Zochitika zogwiritsira ntchito

Mu makina olumikizirana a fiber optical, ma semiconductor optical amplifiers (SOA) angagwiritsidwe ntchito m'malo osiyanasiyana ogwiritsira ntchito kuti awonjezere magwiridwe antchito ndi mtunda wotumizira wa makina olumikizirana. Izi ndi zina mwa njira zomwe zimagwiritsidwa ntchito pogwiritsira ntchito SOA amplifier mu makina olumikizirana a fiber optical:

Choyankhira choyamba: SOAchokulitsa kuwalaingagwiritsidwe ntchito ngati choyatsira mawu poyamba pamalo olandirira kuwala m'makina olumikizirana akutali okhala ndi ulusi wowala wopitilira makilomita 100, kukulitsa kapena kukulitsa mphamvu ya kutulutsa kwa chizindikiro m'makina olumikizirana a ulusi wowala wakutali, motero kulipira mtunda wosakwanira wotumizira womwe umachitika chifukwa cha kutulutsa kochepa kwa zizindikiro zazing'ono. Kuphatikiza apo, SOA ingagwiritsidwenso ntchito kukhazikitsa ukadaulo wokonzanso chizindikiro cha netiweki ya optical m'makina olumikizirana a ulusi wowala.

Kukonzanso kwa chizindikiro cha kuwala konse: Mu ma network a kuwala, pamene mtunda wotumizira umawonjezeka, zizindikiro za kuwala zimachepa chifukwa cha kuchepa kwa mphamvu, kufalikira, phokoso, kugwedezeka kwa nthawi ndi kulankhulana, ndi zina zotero. Chifukwa chake, pakutumiza mtunda wautali, ndikofunikira kulipira zizindikiro za kuwala zomwe zawonongeka kuti zitsimikizire kulondola kwa chidziwitso chotumizidwa. Kukonzanso kwa chizindikiro cha kuwala konse kumatanthauza kukonzanso, kusintha mawonekedwe, ndi kusintha nthawi. Kukulitsa kwina kumatha kuchitika ndi ma amplifiers a kuwala monga ma semiconductor optical amplifiers, EDFA ndi Raman amplifiers (RFA).

Mu makina ozindikira ulusi wa kuwala, ma amplifiers a semiconductor optical (Chokulitsa cha SOA) ingagwiritsidwe ntchito kukulitsa zizindikiro zowunikira, motero kukulitsa kukhudzidwa ndi kulondola kwa masensa. Nazi zina mwazomwe zimagwiritsidwa ntchito pogwiritsira ntchito SOA mu makina owunikira ulusi:

Kuyeza kupsinjika kwa ulusi wa kuwala: Konzani ulusi wa kuwala pa chinthu chomwe kupsinjika kwake kukufunika kuyezedwa. Chinthucho chikakhudzidwa ndi kupsinjika, kusintha kwa kupsinjikako kumabweretsa kusintha pang'ono kutalika kwa ulusi wa kuwala, motero kusintha kutalika kwa nthawi kapena nthawi ya chizindikiro cha kuwala kupita ku sensa ya PD. SOA amplifier imatha kupeza magwiridwe antchito apamwamba pokulitsa ndi kukonza chizindikiro cha kuwala.

Kuyeza kuthamanga kwa ulusi wa kuwala: Mwa kuphatikiza ulusi wa kuwala ndi zinthu zomwe zimakhudzidwa ndi kupanikizika, chinthu chikapanikizika, chimayambitsa kusintha kwa kutayika kwa kuwala mkati mwa ulusi wa kuwala. SOA ingagwiritsidwe ntchito kukulitsa chizindikiro chofooka ichi cha kuwala kuti chikwaniritse kuyeza kuthamanga kwamphamvu kwambiri.

Chojambulira cha semiconductor optical amplifier SOA ndi chipangizo chofunikira kwambiri pakulankhulana kwa ulusi wa kuwala ndi kuzindikira ulusi wa kuwala. Mwa kukulitsa ndi kukonza zizindikiro za kuwala, zimawonjezera magwiridwe antchito a dongosolo ndi kuzindikira kwa kumva. Ntchito izi ndizofunikira kwambiri kuti pakhale kulumikizana kwa ulusi wa kuwala mwachangu, kokhazikika komanso kodalirika komanso kuzindikira kwa ulusi wa kuwala molondola komanso kogwira mtima.
