JDSU Semiconductor fiber laser kukonza

JDSU (tsopano Lumentum ndi Viavi Solutions) ndi kampani yotsogola kwambiri padziko lonse lapansi. Zogulitsa zake za laser zimagwiritsidwa ntchito kwambiri polumikizirana ndi kuwala, kukonza mafakitale, kafukufuku wasayansi ndi zamankhwala. Ma laser a JDSU amadziwika ndi kukhazikika kwawo, moyo wautali komanso kuwongolera bwino. Amaphatikizanso ma semiconductor lasers, fiber lasers ndi solid-state lasers.

2. Ntchito ndi mapangidwe a JDSU lasers

1. Ntchito zazikulu

Kuyankhulana kwa kuwala: kumagwiritsidwa ntchito poyankhulana mofulumira kwambiri (monga DWDM systems, optical modules).

processing mafakitale: laser chodetsa, kudula, kuwotcherera (high-mphamvu CHIKWANGWANI lasers).

Kufufuza kwasayansi: kusanthula kwa spectral, quantum optics, laser radar (LIDAR).

Zida zamankhwala: opaleshoni ya laser, chithandizo cha khungu (monga ma semiconductor lasers).

2. Mapangidwe ake enieni

Mapangidwe apakati a JDSU lasers amasiyanasiyana kutengera mtundu, koma nthawi zambiri amakhala ndi zigawo izi:

Chigawo Ntchito

Laser diode (LD) Imatulutsa kuwala kwa laser, komwe kumapezeka mu semiconductor lasers

Fiber resonator Amagwiritsidwa ntchito mu fiber lasers kuti apititse patsogolo kutulutsa kwa laser

Electro-optic modulator (EOM) Imawongolera kugunda kwa laser / kutulutsa kosalekeza

Temperature control system (TEC) Imakhazikika kutalika kwa laser komanso kupewa kutenthedwa

Optical coupling system Imakulitsa mtundu wa mtengo (monga ma lens ophatikizana)

Drive circuit Imapereka mphamvu yokhazikika kuti iteteze kusinthasintha kwa magetsi

III. Zolakwika zodziwika komanso kuzindikira kwa ma laser a JDSU

1. Laser linanena bungwe mphamvu amachepetsa

Zomwe zingatheke:

Kukalamba kwa laser diode (nthawi zambiri maola 20,000 mpaka 50,000 amoyo).

Kuwonongeka kwa fiber cholumikizira kapena kuwonongeka (monga fumbi, zokala).

Kulephera kwa dongosolo lowongolera kutentha (TEC) kumayambitsa kusuntha kwa mafunde.

Yankho:

Yang'anani ukhondo wa ulusi kumapeto kwa nkhope ndikusintha ngati kuli kofunikira.

Yesani ngati kuyendetsa kwapano kuli kokhazikika, ndikusintha kapena kusintha gawo la LD.

2. Laser sangathe kuyamba

Zifukwa zomwe zingatheke:

Kulephera kwamagetsi (monga kusakwanira kwamagetsi kapena chigawo chachifupi).

Kuwongolera kuwonongeka kozungulira (monga PCB kutenthedwa).

Choyambitsa chitetezo chachitetezo (monga kutentha kosakwanira).

Yankho:

Yang'anani ngati voteji yamagetsi ikugwirizana ndi zomwe mukufuna (monga 5V/12V).

Yambitsaninso dongosolo ndikuwunika zolakwika (zitsanzo zina zimathandizira kudziyesa).

3. Kuwonongeka kwa mtengo wa mtengo (kuchuluka kwa M²)

Zifukwa zomwe zingatheke:

Zigawo za kuwala (monga magalasi, zowunikira) ndizoipitsidwa kapena kusinthidwa.

Utali wopindika wa CHIKWANGWANI ndi wocheperako, zomwe zimapangitsa kusokonekera.

Yankho:

Chotsani kapena sinthaninso zinthu zowoneka bwino.

Onetsetsani kuti kuyika kwa ulusi kumakwaniritsa zofunikira zochepa zopindika.

IV. Njira zosamalira za JDSU laser

1. Kusamalira tsiku ndi tsiku

Kuyeretsa zigawo za kuwala:

Gwiritsani ntchito thonje lopanda fumbi + mowa wa isopropyl kuyeretsa nkhope ndi mandala.

Pewani kukhudza pamwamba optical mwachindunji ndi manja anu.

Onani dongosolo lozizira:

Tsukani fumbi la fan nthawi zonse kuwonetsetsa kuti njira yodutsa mpweya ilibe chotchinga.

Onani magawo a laser:

Lembani mphamvu zotulutsa ndi kukhazikika kwa kutalika kwa mafunde, ndikuthetsa zovuta nthawi yomweyo.

2. Kusamalira nthawi zonse (kulangizidwa miyezi 6 mpaka 12 iliyonse)

Sinthani magawo okalamba:

Laser diode (LDs) iyenera kusinthidwa moyo wawo ukatha.

Yang'anani zolumikizira za fiber ndikuzisintha ngati zatha kwambiri.

Sinthani mawonekedwe a Optical:

Gwiritsani ntchito chowunikira kuti muzindikire mtengo wa M² ndikusintha momwe collimator ilili.

3. Njira zodzitetezera kusungirako nthawi yayitali

Zofunikira zachilengedwe:

Kutentha 10 ~ 30 ° C, chinyezi <60% RH.

Pewani kugwedezeka ndi kusokoneza kwamphamvu kwa maginito.

Kukonza mphamvu:

Kwa ma lasers omwe sanagwiritsidwe ntchito kwa nthawi yayitali, tikulimbikitsidwa kuyatsa kwa ola la 1 mwezi uliwonse kuti mupewe kukalamba kwa capacitor.

V. Njira zodzitetezera zowonjezera moyo wa laser

Mphamvu yokhazikika: Gwiritsani ntchito magetsi okhazikika + UPS kuti mupewe kusinthasintha kwamagetsi kuti zisawononge dera.

Ntchito yokhazikika:

Pewani kuyatsa ndi kuzimitsa pafupipafupi (zolowera> masekondi 30).

Kugwiritsa ntchito mphamvu mopitirira muyeso ndikoletsedwa (monga kupyola pakali pano ndi 10%).

Chitsimikizo cha fumbi ndi chinyezi:

Gwiritsani ntchito pamalo oyera ndikuyika chivundikiro cha fumbi ngati kuli kofunikira.

Konzekerani desiccant kapena dehumidifier m'malo achinyezi.

Sungani ma parameter pafupipafupi:

Sungani data yoyezera fakitale kuti mubwezeretse zolakwika mosavuta.

VI. Chidule

Kudalirika kwakukulu kwa ma laser a JDSU kumadalira kugwiritsa ntchito moyenera komanso kukonza pafupipafupi. Mwa kuyeretsa zigawo zowoneka bwino, kuyang'anira kutentha kwa kutentha, ndikusintha ziwalo zokalamba panthawi yake, kulephera kukhoza kuchepetsedwa kwambiri ndipo moyo wa zipangizo ukhoza kuwonjezedwa. Pazogwiritsa ntchito zovuta (monga kulumikizana kwa kuwala), tikulimbikitsidwa kukhazikitsa dongosolo lokonzekera chitetezo ndikusunga kulumikizana ndi chithandizo choyambirira chaukadaulo.
