Gabaɗaya, ƙarfin haske na transceiver fiber na gani ko ƙirar gani shine kamar haka: multimode yana tsakanin 10db da -18db; Yanayin guda ɗaya shine 20km tsakanin -8db da -15db; kuma yanayin guda ɗaya shine 60km yana tsakanin -5db da -12db tsakanin. Amma idan hasken wutar lantarki na fiber optic transceiver ya bayyana tsakanin -30db da -45db, to da alama wannan fiber optic transceiver yana da matsala.
Yaya za a yi hukunci ko akwai matsala tare da transceiver fiber optic?
(1) Da farko, duba idan hasken mai nuna alamar fiber transceiver na gani ko module na gani da hasken mai nunin tashar tashar murɗaɗiyar biyu suna kunne.
a. Idan alamar FX na transceiver a kashe, da fatan za a tabbatar ko haɗin fiber yana da haɗin kai? Ɗayan ƙarshen jumper fiber yana haɗuwa a layi daya; an haɗa ɗayan ƙarshen a cikin yanayin giciye.
b. Idan alamar tashar tashar jiragen ruwa (FX) mai nuna A transceiver tana kunne kuma alamar tashar tashar ta gani (FX) mai nunin B transceiver ta kashe, laifin yana gefen A transceiver: yuwuwar ɗayan ita ce: A transceiver (TX). tashar jiragen ruwa ba ta da kyau saboda tashar tashar gani (RX) na mai karɓar B ba ta karɓar siginar gani; wata yuwuwar kuma ita ce: akwai matsala tare da wannan hanyar haɗin fiber na tashar tashar watsawar gani ta A transceiver (TX) (ana iya karye kebul na gani ko jumper na gani).
c. Alamar murɗaɗɗen biyu (TP) tana kashe. Da fatan za a tabbatar cewa haɗar murɗaɗɗen ba daidai ba ne ko haɗin ba daidai bane? Da fatan za a yi amfani da mai gwada ci gaba don gwadawa (duk da haka, murɗaɗɗen fitilun masu nuna alama na wasu masu juyawa dole ne su jira har sai an haɗa hanyar haɗin fiber).
d. Wasu transceivers suna da tashar jiragen ruwa na RJ45 guda biyu: (ToHUB) yana nuna cewa layin haɗi zuwa tashar jiragen ruwa.canzalayi ne madaidaiciya; (ToNode) yana nuna cewa layin haɗi zuwacanzalayi ne na tsallake-tsallake.
e. Wasu kari na gashi suna da MPRcanzaa gefe: yana nufin cewa layin haɗin zuwacanzalayi ne madaidaiciya; DTEcanza: layin haɗi zuwacanzayanayin giciye ne.
(2) Ko an karye kebul na gani da kuma jumper na fiber na gani
a. Haɗin kebul na gani da gano cire haɗin: yi amfani da hasken walƙiya, hasken rana, jiki mai haske don haskaka ƙarshen mahaɗar kebul na gani ko hada biyu; duba idan akwai haske a bayyane a daya karshen? Idan akwai haske mai gani, yana nuna cewa kebul na gani bai karye ba.
b. Gano kan-kashe haɗin fiber na gani: yi amfani da walƙiya laser, hasken rana, da sauransu don haskaka ƙarshen tsallen fiber ɗaya; gani idan akwai bayyane haske a daya gefen? Idan akwai hasken da ake iya gani, mai tsallen fiber ba ya karye.
(3) Ko rabin/cikakken yanayin duplex ba daidai ba ne
Wasu transceivers suna da FDXmasu sauyawaa gefe: cikakken duplex; HDXmasu sauyawa: rabin duplex.
(4) Gwaji tare da mitar wutar lantarki
Ƙarfin haske na transceiver fiber na gani ko ƙirar gani a ƙarƙashin yanayi na al'ada: yanayin da yawa: tsakanin -10db da -18db; Yanayin guda 20 kilomita: tsakanin -8db da -15db; Yanayin guda 60 kilomita: tsakanin -5db da -12db; Idan hasken wutar lantarki na fiber optic transceiver yana tsakanin -30db-45db, to ana iya yanke hukunci cewa akwai matsala tare da wannan fiber optic transceiver.
