Menene hanyoyin haɗin fiber?
1. Haɗi mai aiki:
Haɗin aiki hanya ce ta haɗa shafi zuwa shafi ko wani shafi zuwa kebul na fiber optic ta amfani da na'urorin haɗin fiber na gani daban-daban (fulogi da soket).Wannan hanya mai sassauƙa ce, mai sauƙi, dacewa, kuma abin dogaro, kuma galibi ana amfani da ita a cikin hanyoyin sadarwar kwamfuta a cikin gine-gine.Attenuation na yau da kullun shine 1dB / mai haɗawa.
2. Haɗin gaggawa (wanda kuma aka sani da) narkewar sanyi:
Haɗin gaggawa yana amfani da hanyoyin inji da sinadarai don gyarawa da haɗa filaye biyu na gani tare.Babban halayyar wannan hanyar ita ce haɗin haɗin yana da sauri kuma abin dogara, kuma ƙayyadaddun yanayin haɗin haɗin shine 0.1-0.3dB / aya.
Ana iya shigar da su cikin masu haɗin kai kuma a sanya su cikin kwas ɗin fiber optic.Mai haɗawa yana cinye 10% zuwa 20% na haske, amma yana sauƙaƙa don sake saita tsarin. Duk da haka, haɗin haɗin zai kasance maras tabbas na dogon lokaci kuma attenuation zai karu sosai, don haka ana iya amfani dashi kawai don gaggawa a cikin gaggawa. dan kankanin lokaci.
Ana iya haɗa shi da injina.Don yin wannan, sanya ƙarshen zaruruwa guda biyu a hankali a hankali a cikin bututu kuma ku matsa su tare.Ana iya daidaita fiber ɗin ta hanyar haɗin gwiwa don haɓaka siginar.Haɗin kai na injina yana buƙatar kusan mintuna 5 don horar da ma'aikata don kammalawa, kuma asarar hasken shine kusan 10%.
3. Haɗin fiber na dindindin (wanda kuma aka sani da zafi mai zafi):
Irin wannan haɗin yana amfani da fitarwar lantarki don haɗawa da haɗa wuraren haɗin fiber.Gabaɗaya ana amfani da shi don haɗin nisa, na dindindin ko madaidaiciya madaidaiciya.Babban fasalinsa shine haɓakar haɗin kai shine mafi ƙanƙanta tsakanin duk hanyoyin haɗin gwiwa, tare da ƙimar ƙimar 0.01-0.03dB / aya.
Koyaya, lokacin haɗawa, ana buƙatar kayan aiki na musamman (na'urar walda) da ayyukan ƙwararru, kuma wurin haɗin yana buƙatar kiyaye shi ta wani akwati na musamman.Za a iya haɗa zarurukan biyu tare don samar da ingantaccen haɗi.
Fiber da aka kafa ta hanyar haɗin kai kusan iri ɗaya ne da fiber guda ɗaya, amma akwai ɗan ragewa.Ga dukkan hanyoyin haɗin kai guda uku, akwai tunani a mahaɗin, kuma ƙarfin da aka nuna yana hulɗa da siginar.
Wajibi ne a fahimci asarar fiber na gani don yin amfani da fiber na gani da kyau.Babban aikin Fluke's CertiFiber Pro Optical Loss Tester asarar fiber shine gwada asara da gazawar sanadin fiber.
Fluke's CertiFiber Pro na gani asarar Gwajin asarar fiber na iya:
1. Gwajin atomatik na biyu na biyu - (sau huɗu cikin sauri fiye da masu gwajin gargajiya) ya haɗa da: ma'aunin hasara na gani akan filaye biyu na tsayin raƙuman ruwa biyu, ma'aunin nesa da lissafin kasafin kuɗi na gani.
2. Ba da izinin wucewa ta atomatik / gazawar bincike dangane da matsayin masana'antu ko iyakokin gwajin al'ada
3. Gano hanyoyin gwajin da ba daidai ba wanda ke haifar da sakamakon "asara mara kyau".
4.Onboard (USB) dubawa kamara yana rikodin hoton ƙarshen fiber
5. Adaftar mita wutar lantarki akwai don kowane nau'in haɗin haɗin kai (SC, ST, LC, da FC) don ingantacciyar hanyar tunani guda ɗaya.
6.Built-in video kuskure locator for asali bincike da polarity ganewa
7. Ƙarfin ma'auni na dual wavelength akan fiber guda ɗaya yana ba da damar yin amfani da mai gwadawa a cikin aikace-aikacen da ke buƙatar haɗin fiber guda ɗaya kawai.
Ba a buƙatar ƙarin kayan aiki ko matakai don biyan bukatun TIA-526-14-B da IEC 61280-4-1 buƙatun sauyin zobe.
Menene bambancin kebul na gani da fiber na gani
Kebul na gani yana kunshe da takamaiman adadin fiber na gani.An lulluɓe tsakiyar tsakiya da kusoshi da kariyar kariya don sadarwa da watsa bayanai mai girma mai nisa.
