Iyakokin Alƙalami na Ja-Haske: Me yasa Suke Matsayin Shiga-Kawai

Alkalami mai haske mai ja shine kayan aiki mafi arha kuma mafi sauƙi don magance matsalar fiber - danna maɓallin, allurar jan haske a cikin fiber ɗin, kuma ga inda hasken ke fitowa. Kudinsa dubun zuwa ɗaruruwan yuan kuma daidaitaccen kayan aiki ne ga kowane injiniyan fiber. Amma alƙalami masu haske suna da iyakoki na asali guda uku.

Na farko: rashin isasshen iko. Alƙalamai masu haske na yau da kullun suna aiki a ƙarƙashin 1mW, ana amfani da su kawai don gwajin tsalle-tsalle na fiber na cikin gida tsakanin 500m. Bayan 1km, hasken ja yana karkata zuwa ganuwa. Na biyu: rashin daidaiton tsayin igiyar ruwa. Alƙalamai masu haske suna fitar da haske mai haske na 650nm mai gani, yayin da tsarin fiber ke watsa hasken infrared 1310nm ko 1550nm - tsayin raƙuman ruwa daban-daban, don haka alƙalami mai haske ba zai iya maye gurbin OPM don auna ainihin ikon gani na tsarin ba. Na uku: babu ikon karantawa. Alkalami mai haske yana gaya muku 'fiber ɗin yana haɗa' ko 'fiber ɗin ya karye' - ba zai iya gaya muku 'ƙararfin siginar' ko 'menene asarar hanyar haɗin gwiwa ba.'

Saboda haka, alƙalami mai haske ya dace kawai a matsayin bincike na ƙarshe - bayan gwajin OPM, yi amfani da shi don tabbatar da sauri ko mai tsalle yana da hutu na bayyane. Amma ba zai iya maye gurbin OPM ba, kuma ba zai iya kammala cikakken ƙimar haɗin fiber da kansa ba.

Duk-in-Daya Hasken Hasken Ja: Haɓaka Uku Sama da Alƙalami-Jan Haske

Haɗe-haɗen tushen hasken ja a cikin na'urori-cikin-ɗaya (kamar jerin PK56B–E) yana ba da mahimman haɓakawa guda uku akan alƙalami masu haske-ja. Na farko: iko. PK56B–E jan hasken wuta ya tashi daga 2mW zuwa 20mW - sau 2 zuwa 20 fiye da na alƙalamai masu haske na yau da kullun. Ƙarfin da ya fi girma yana nufin tsayin nisan ganowa da mafi kyawun juriya ga hasken yanayi. A cikin yanayin waje mai haske a firam ɗin rarraba fiber, 2mW ja haske na iya zama gaba ɗaya ganuwa, yayin da 10mW ya kasance a bayyane a bayyane.

Na biyu: daidaita tsayin igiyoyin ruwa. Madogarar hasken ja da OPM a cikin duk-in-daya suna raba hanyar haɗin fiber iri ɗaya da tsarin daidaitawa. Lokacin amfani da tushen hasken ja don magance matsala, OPM na iya auna ƙarfin hasken ja a lokaci guda - musamman mai amfani lokacin gyara kurakuran amplifier na gani (EDFA): allurar hasken gwaji tare da tushen hasken ja, sannan auna ƙarfin fitarwa tare da OPM, yana kammala matakai biyu cikin ɗaya.

Na uku: ingancin aiki. Juyawa tsakanin yanayin ja haske da yanayin gwajin wuta akan duk-in-one yana buƙatar latsa maɓalli ɗaya. A cikin warware matsalar hanyar haɗin fiber, daidaitaccen kwarara shine: ikon gwadawa (ƙayyade idan haɗin yana al'ada) → canzawa zuwa yanayin haske ja (gano wurin hutu) → gyara → sake gwada ƙarfin (tabbatar gyara). Tare da na'urori daban-daban, wannan kwarara yana buƙatar sauyawa tsakanin na'urori biyu, aƙalla ninka lokaci.

Zaɓi Ƙarfin Hasken Ja: 2mW / 5mW / 10mW / 20mW

Samfuran PK56B–E guda huɗu sun bambanta da ƙarfin hasken ja: 10mW, 2mW, 5mW, da 20mW. Zaɓin ya dogara da mafi tsayin nisan fiber da kuke buƙatar gwadawa da yanayin aikin ku.

2mW (PK56C): dace da gwajin tsalle na fiber na cikin gida tsakanin 1km. Mafi ƙarancin wutar lantarki, rayuwar baturi mafi tsayi, mafi ƙarancin farashi. Ya dace da hanyoyin haɗin fiber na ɗan gajeren lokaci a cikin cibiyoyin bayanai da gine-ginen ofis.

5mW (PK56D): daidaitaccen zaɓi. Ya dace da hanyoyin haɗin fiber matsakaici na 2-3km. A bayyane yake a bayyane a cikin gida da na waje. Ya dace da yawancin tashar tashar sadarwa da gwajin filin FTTx.

10mW (PK56B): dace da hanyoyin haɗin fiber mai tsayi na 3-5km. Har yanzu a bayyane a cikin mahalli na waje, dacewa da kulawa na yau da kullun da magance matsalar fiber gangar jikin.

20mW (PK56E): digiri na ƙwararru. Ya dace da hanyoyin haɗin fiber sama da 5km. A bayyane yake a bayyane ko da a cikin hasken rana mai haske, wanda ya dace da gyaran kebul na akwati da matsayi mai nisa na OTDR. Lura: Hasken ja na 20mW na iya zama haɗari ga idanu a kusa da kewayon - guje wa kallon ƙarshen fiber ɗin kai tsaye.

Dabarun Aiki Hudu don Gwajin Hasken Ja

Gwajin jajayen haske yana bayyana mai sauƙi, amma dabaru da yawa na iya inganta inganci sosai. Na farko: 'alurar rigakafi.' Dogayen hanyar haɗin fiber na iya samun ƙulli da yawa. Idan an yi allurar jan haske a cikin hanyar haɗin gaba ɗaya kuma bai wuce ta ba, kar a duba tsawon tsayin gani - allurar jan haske ta kashi: allurar a farkon ƙulli na farko sannan a duba ko jan haske ya kai na biyu. Wannan da sauri keɓe wanne sashi ke da matsala.

Na biyu: 'lanƙwasa yabo.' Jajayen haske a cikin fiber yana fitowa a cikin lanƙwasa mai ƙarfi. Lokacin warware matsalar fiber, matsar da alƙalamin haske ja tare da hanyar fiber - kusa da wurin kuskure, jan haske yana haskakawa ko yawo. Wannan dabara tana da amfani musamman don magance ɓoyayyun kurakuran kamar 'fiber da beraye ke tauna' ko 'fiber da aka niƙa ta hanyar gini.'

Na uku: 'tace hasken yanayi.' A cikin waje mai haske ko ƙaƙƙarfan yanayi mai haske, hasken yanayi na iya mamaye jajayen haske. Yi amfani da aikin 'kololuwar riƙe' duk-in-ɗayan - tushen hasken ja yana aiki a yanayin juzu'i, kuma samfuran OPM kawai a cikin taga bugun bugun jini, tana tace tsangwama na yanayi. PK56B–E jerin duk suna goyan bayan yanayin haske ja.

Na hudu: 'kallon karshen fuska farko.' Kafin allurar jan haske, duba tsaftar ƙarshen fuskar fiber. Idan fuskar ƙarshen ta yi ƙura, haske mai ja yana watsawa a ƙarshen fuska, yana bayyana a matsayin hutu, lokacin da yake datti kawai. Bincika tare da ruwan tabarau mai girma kuma a tsaftace idan ya cancanta kafin gwaji - wannan yana guje wa ɗimbin ƙima.

Shawarwari Mai Aiki: Haɗa Gwajin Hasken Ja cikin Tsarin Kula da Fiber

Don ƙungiyoyin kulawa, haɗa gwajin haske na ja cikin kiyaye hanyar haɗin fiber na yau da kullun. Don sabbin hanyoyin haɗin fiber, yi tabbacin ci gaba da hasken ja yayin karɓa. Yayin sabis, yi matsalar jan haske a kowane wata (wata-wata don hanyoyin haɗin kai masu mahimmanci). Bayan kuskure, yi amfani da tushen hasken ja don gano wurin hutun farko, sannan yi amfani da OPM don tabbatar da gyara.

Don masu siye har yanzu suna cikin lokacin zaɓi, ba da fifiko ga na'urori gaba ɗaya tare da tushen hasken ja. Yayin da raka'a-cikin-ɗaya ke tsada fiye da OPMs na tsaye, dawowar saka hannun jari yana da mahimmanci idan aka auna shi akan ribar inganci da rage lokacin gyara kuskure.
