2.Idan alamar tashar tashar jiragen ruwa (FX) mai nuna alamar transceiver ba ta haskakawa ba, ƙayyade idan haɗin fiber yana da haɗin kai.Ana haɗa jumper na fiber a layi daya kuma ɗayan shine haɗin giciye.
3.The Twisted biyu (TP) nuna alama ba ya haske.Da fatan za a tabbatar cewa murɗaɗɗen kebul ɗin biyu ba daidai ba ne ko an haɗa shi da kuskure.Da fatan za a yi amfani da ma'aunin ci gaba don dubawa.(Duk da haka, wasu ma'anoni masu murɗaɗɗen nau'in transceivers dole ne su jira har sai an kunna hanyar haɗin fiber).
4.Wasu transceivers suna da tashoshin RJ45 guda biyu: (ToHUB) yana nuna cewa layin haɗin da ke haɗa maɓallan shine madaidaiciyar layi ta hanyar madaidaiciya.(ToNode) yana nuna cewa layin haɗin da ke haɗa masu sauyawa shine layin giciye.
5.Wasu masu watsawa suna da maɓallin MPR a gefe: layin haɗin da ke haɗa maɗaukaki shine yanayin layi madaidaiciya.Maɓallin DTE: layin haɗin da ke haɗa maɗaukaki shine yanayin giciye.
Mataki na 2: Bincika ko akwai matsala tare da jumper fiber da na USB?
1.Optical fiber connection on-off detection: yi amfani da hasken wuta na Laser, hasken rana, da dai sauransu don haskaka tsallen fiber. Dubi idan akwai haske mai gani a ɗayan ƙarshen?Idan akwai hasken da ake iya gani, mai tsallen fiber ba ya karye.
2.Cable break detection: yi amfani da hasken walƙiya na laser, hasken rana, mai haskakawa don haskaka haɗin kebul ko ma'amala. Duba idan akwai haske mai gani a ɗayan ƙarshen?Idan akwai hasken da ake iya gani, kebul ɗin ba ya karye.
Mataki na 3: Shin rabin/cikakkiyar hanyar duplex ba daidai ba ne?
Wasu transceivers suna da FDX masu sauyawa a gefe: cikakken duplex;HDX sauyawa: rabin duplex.
Mataki na 4: Yin amfani da gano kayan aikin mitar wutar gani
Ƙarfin haske na mai ɗaukar hoto ko na'urar gani a ƙarƙashin yanayin al'ada: multimode: -10db-18db;Yanayin guda 20km: -8db–15db;Yanayin guda 60km: -5db–12db Idan hasken wutar lantarki na na'urar tantancewa yana tsakanin -30db-45db, to ana iya yanke hukunci cewa akwai matsala tare da wannan transceiver.
Ya kamata masu ɗaukar gani na gani su kula da al'amura
Don kare kanka da sauƙi, yana da kyau a sami salon tambaya da amsa, wanda za'a iya samu a kallo.
1.Shin mai ɗaukar hoto da kansa yana goyan bayan cikakken duplex da rabin duplex?
Wasu kwakwalwan kwamfuta a kasuwa na iya amfani da yanayin cikakken duplex kawai a halin yanzu, kuma ba za su iya tallafawa rabin duplex ba.Idan kun haɗa zuwa wasu nau'ikan masu sauyawa (SWITCH) ko hub (HUB), kuma tana amfani da yanayin rabin duplex, tabbas zai haifar da rikice-rikice masu tsanani da asarar fakiti.
2.An gwada shi don haɗin kai tare da sauran transceivers fiber optic?
A halin yanzu, ana samun ƙarin na'urorin gani a kasuwa.Misali, idan ba a gwada daidaiton nau'ikan nau'ikan transceivers daban-daban a baya ba, hakanan zai haifar da asarar fakiti, dogon lokacin watsawa, da sauri da jinkiri.
3.Shin akwai na'urar tsaro don hana asarar fakiti?
Wasu masana'antun suna amfani da yanayin canja wurin bayanai don rage farashin lokacin da ke kera fiber optic transceivers.Babban hasara na wannan hanyar ita ce watsawar ba ta da kwanciyar hankali da asarar fakiti, kuma mafi kyawun ita ce yin amfani da ƙirar layin buffer, wanda zai iya kiyaye amincin bayanan. asarar fakiti.
4. Temperatuur daidaitawa?
Lokacin da ake amfani da fiber optic transceiver kanta, zai haifar da zafi mai zafi.Lokacin da zafin jiki ya yi yawa (ba fiye da 50 ° C ba), ko fiber optic transceiver yana aiki akai-akai yana da mahimmancin la'akari da abokan ciniki!
5.Shin akwai mizanin IEEE802.3u?
Idan transceiver na gani ya hadu da ma'aunin IEEE802.3, wato, ana sarrafa lokacin jinkiri a 46 ragowa.Idan ya wuce 46 ragowa, za a gajarta tazarar da na'urar gani ta gani.
6.Bayan-tallace-tallace sabis:
Don sa sabis na tallace-tallace ya amsa da sauri da wuri, ana ba da shawarar cewa abokan ciniki su sayi transceivers fiber-optic bisa ga ƙarfin masana'anta, fasaha, suna da sauran kamfanoni.
