Muri rusange, imbaraga za luminous ya optique fibre transceiver cyangwa module ya optique nuburyo bukurikira: multimode iri hagati ya 10db na -18db;uburyo bumwe ni 20km hagati ya -8db na -15db;nuburyo bumwe ni 60km iri hagati ya -5db na -12db hagati.Ariko niba imbaraga za luminous ya fibre optique transceiver igaragara hagati ya -30db na -45db, noneho birashoboka cyane ko iyi fibre optique ifite ikibazo.
Nigute ushobora kumenya niba hari ikibazo cya fibre optique transceiver?
.
a.Niba igipimo cya FX cyerekana transceiver kizimye, nyamuneka wemeze niba fibre ihuza ihuza?Impera imwe ya fibre isimbuka ihujwe kuburinganire;iyindi mpera ihujwe muburyo bwambukiranya.
b.Niba icyerekezo cya optique (FX) cyerekana A transceiver kiri kandi icyambu cya optique (FX) cyerekana B transceiver cyarazimye, ikosa riri kuruhande rwa A transceiver: ikintu kimwe gishoboka ni: Trans transiver (TX) optique yoherejwe icyambu ni kibi kuko icyambu cya optique (RX) cya B transceiver kitakira ibimenyetso bya optique;ikindi gishoboka ni: hari ikibazo kijyanye niyi fibre ihuza icyambu cyohereza imiyoboro ya A transceiver (TX) (insinga ya optique cyangwa optique ishobora gusimbuka).
c.Ikimenyetso cyahinduwe (TP) kirahari.Nyamuneka menya neza ko guhuza kugoretse guhuza ari bibi cyangwa guhuza ni bibi?Nyamuneka koresha ikizamini cyo gukomeza kugirango ugerageze (icyakora, amatara yerekanwe yerekana amatara ya transcevers agomba gutegereza kugeza fibre ihuza).
d.Transceivers zimwe zifite ibyambu bibiri bya RJ45: (ToHUB) byerekana ko umurongo uhuza umurongo uhinduka umurongo ugororotse;(ToNode) yerekana ko umurongo uhuza kuri switch ari umurongo wambukiranya.
e.Kwagura umusatsi bimwe bifite MPR ihinduka kuruhande: bivuze ko umurongo uhuza umurongo uhinduka umurongo ugororotse;Guhindura DTE: umurongo uhuza kuri switch ni uburyo bwambukiranya.
(2) Niba insinga ya optique na fibre optique yasimbutse
a.Umuyoboro wa optique uhuza no gutahura: koresha itara rya laser, urumuri rwizuba, umubiri wumucyo kugirango umurikire impera imwe yumurongo wa optique cyangwa guhuza;reba niba hari urumuri rugaragara kurundi ruhande?Niba hari urumuri rugaragara, byerekana ko insinga ya optique itavunitse.
b.Kumenyekanisha kumurongo wa fibre optique: koresha laser flashlight, urumuri rwizuba, nibindi kugirango umurikire impera imwe ya fibre jumper;reba niba hari urumuri rugaragara kurundi ruhande?Niba hari urumuri rugaragara, gusimbuka fibre ntabwo byacitse.
(3) Niba igice / cyuzuye duplex uburyo aribeshya
Transceivers zimwe zifite FDX zihindura kuruhande: duplex yuzuye;Guhindura HDX: igice cya duplex.
(4) Gerageza ukoresheje metero ya optique
Imbaraga zamurika za optique ya fibre optique cyangwa module ya optique mubihe bisanzwe: uburyo bwinshi: hagati ya -10db na -18db;uburyo bumwe-kilometero 20: hagati ya -8db na -15db;uburyo bumwe-kilometero 60: hagati ya -5db na -12db;Niba imbaraga za luminous ya fibre optique transceiver iri hagati ya -30db-45db, noneho birashobora kugaragara ko hari ikibazo cyiyi fibre optique.
