JDSU Semiconductor fibre laser yo gusana

JDSU (ubu ni Lumentum na Viavi Solutions) ni isosiyete ikora optoelectronics ku isi. Ibicuruzwa byayo bya laser bikoreshwa cyane mubitumanaho bya optique, gutunganya inganda, ubushakashatsi bwa siyansi nubuvuzi. Laser ya JDSU izwiho guhagarara neza, kuramba no kugenzura neza. Harimo cyane cyane lazeri ya semiconductor, laseri ya fibre hamwe na lazeri ikomeye.

2. Imikorere nuburyo bwa laseri ya JDSU

1. Ibikorwa by'ingenzi

Itumanaho ryiza: rikoreshwa muburyo bwihuse bwitumanaho rya fibre itumanaho (nka sisitemu ya DWDM, modul optique).

Gutunganya inganda: ikimenyetso cya laser, gukata, gusudira (fibre fibre ikomeye).

Ubushakashatsi bwa siyansi yubushakashatsi: isesengura ryerekana, kwant optique, laser radar (LIDAR).

Ibikoresho byubuvuzi: kubaga laser, kuvura uruhu (nka lazeri ya semiconductor).

2. Imiterere isanzwe yimiterere

Imiterere yibanze ya laseri ya JDSU iratandukanye bitewe n'ubwoko, ariko mubisanzwe harimo ibice by'ingenzi bikurikira:

Imikorere yibigize

Laser diode (LD) Itanga urumuri rwa laser, rusanzwe ruboneka muri lazeri ya semiconductor

Fibon resonator Yifashishwa muri fibre ya fibre kugirango yongere umusaruro wa laser

Moderi ya electro-optique (EOM) Igenzura laser pulse / ibisohoka bikomeza

Sisitemu yo kugenzura ubushyuhe (TEC) Ihindura uburebure bwa laser kandi ikarinda ubushyuhe bwinshi

Sisitemu yo guhuza optique Ihindura ubwiza bwibiti (nko gukusanya lens)

Umuzunguruko wa Drive Utanga amashanyarazi ahamye kugirango wirinde ihindagurika ryingufu

III. Amakosa asanzwe no gusuzuma laseri ya JDSU

1. Imbaraga za Laser zisohoka imbaraga ziragabanuka

Impamvu zishoboka:

Laser diode gusaza (mubisanzwe amasaha 20.000 kugeza 50.000 yubuzima).

Guhuza fibre kwanduza cyangwa kwangirika (nkumukungugu, gushushanya).

Kunanirwa kwa sisitemu yo kugenzura ubushyuhe (TEC) itera umuvuduko wumurongo.

Igisubizo:

Reba isuku yisura ya fibre hanyuma usimbure nibiba ngombwa.

Gerageza niba ibiyobora bigenda bihamye, hanyuma uhindure cyangwa usimbuze LD module.

2. Lazeri ntishobora gutangira

Impamvu zishoboka:

Kunanirwa kw'amashanyarazi (nk'amashanyarazi adahagije cyangwa umuyoboro mugufi).

Kugenzura ibyangiritse byumuzunguruko (nka PCB yatwitse).

Umutekano uhuza imbarutso (nko kugabanuka k'ubushyuhe).

Igisubizo:

Reba niba amashanyarazi atanga amashanyarazi yujuje ibisobanuro (nka 5V / 12V).

Ongera utangire sisitemu hanyuma urebe kode yamakosa (moderi zimwe zishyigikira kwipimisha).

3. Kwangirika kw'ibiti (kwiyongera M² agaciro)

Impamvu zishoboka:

Ibikoresho byiza (nka lens, indangururamajwi) byanduye cyangwa byuzuye.

Fibre yunamye radiyo ni nto cyane, bivamo kugoreka uburyo.

Igisubizo:

Sukura cyangwa usubiremo ibice bya optique.

Menya neza ko kwishyiriraho fibre byujuje byibura radiyo isabwa.

IV. Uburyo bwo gufata neza laser ya JDSU

1. Kubungabunga buri munsi

Gusukura ibice bya optique:

Koresha ipamba idafite ivumbi + isopropyl alcool kugirango usukure fibre ya finale na lens.

Irinde gukora ku butaka bwa optique ukoresheje amaboko yawe.

Reba uburyo bwo gukonjesha:

Sukura umukungugu wumufana buri gihe kugirango umenye neza ko umuyoboro wumwuka utabujijwe.

Kurikirana ibipimo bya laser:

Andika ibisohoka imbaraga nuburebure bwumurongo, kandi uhite ukemura ibibazo bidasanzwe.

2. Kubungabunga buri gihe (bisabwa buri mezi 6 kugeza 12)

Simbuza ibice bishaje:

Laser diode (LDs) igomba gusimburwa nyuma yubuzima bwabo burangiye.

Reba fibre ihuza hanyuma uyisimbuze niba yambaye cyane.

Hindura sisitemu ya optique:

Koresha isesengura ryibiti kugirango umenye agaciro ka M² hanyuma uhindure umwanya wa collimator.

3. Kwirinda kubika igihe kirekire

Ibisabwa ku bidukikije:

Ubushyuhe 10 ~ 30 ° C, ubuhehere <60% RH.

Irinde kunyeganyega hamwe nimbaraga zikomeye za magneti.

Kubungabunga amashanyarazi:

Kuri laseri zidakoreshwa igihe kinini, birasabwa gukoresha amashanyarazi kumasaha 1 buri kwezi kugirango wirinde gusaza.

V. Ingamba zo kwirinda zo kwagura ubuzima bwa laser

Amashanyarazi ahamye: Koresha amashanyarazi ahamye amashanyarazi + UPS kugirango wirinde ihindagurika rya voltage kwangiza uruziga.

Igikorwa gisanzwe:

Irinde imbaraga nyinshi kuri no kuzimya (intera> amasegonda 30).

Gukoresha ingufu nyinshi birabujijwe (nko kurenga igipimo cyagenwe na 10%).

Umukungugu nubushuhe:

Koresha ahantu hasukuye hanyuma ushyireho umukungugu nibiba ngombwa.

Koresha ibikoresho bya desiccant cyangwa dehumidifier ahantu h'ubushuhe.

Wibike ibipimo buri gihe:

Bika amakuru ya kalibrasi yinganda kugirango byoroshye gukira amakosa.

VI. Incamake

Kwizerwa gukomeye kwa JDSU biterwa no gukoresha neza no kubungabunga buri gihe. Mugusukura ibice bya optique, kugenzura ubushyuhe, no gusimbuza ibice byashaje mugihe gikwiye, igipimo cyo kunanirwa kirashobora kugabanuka cyane kandi ubuzima bwibikoresho burashobora kongerwa. Kubikorwa bikomeye (nk'itumanaho rya optique), birasabwa gushyiraho gahunda yo kubungabunga ibidukikije no gukomeza itumanaho hamwe nubufasha bwa tekiniki bwambere.
