Guud ahaan, awoodda iftiinka ee transceiver fiber optic ama module indhaha waa sida soo socota: multimode waa inta u dhaxaysa 10db iyo -18db; hal hab waa 20km inta u dhaxaysa -8db iyo -15db; iyo hal hab waa 60km u dhexeeya -5db iyo -12db inta u dhaxaysa. Laakin haddii awooda iftiinka ee fibre optic transceiver ay u muuqato inta u dhaxaysa -30db iyo -45db, markaa waxay aad ugu badan tahay in transceiver fiber optic-gani uu leeyahay dhibaato.
Sidee lagu qiyaasaa in ay dhibaato ka jirto transceiver fiber optic?
(1) Marka hore, arag haddii iftiinka tusaha ee fibre-soo-saarka fiilada indhaha ama moduleka indhaha iyo iftiinka tusaha ee dekedda lamaanaha ah ee qalloocan ay shidan yihiin.
a. Haddii tilmaame FX ee transceiver uu dansan yahay, fadlan xaqiiji in isku xirka fiber-ku uu yahay mid isku xiran? Mid ka mid ah dhammaadka boodboodka fiber-ka ayaa isku xiran; dhamaadka kale wuxuu ku xiran yahay habka iskutallaabta.
b. Haddii tusaha dekedda indhaha (FX) ee transceiver A uu shido oo tusaha dekedda indhaha (FX) ee transceiver-ka B uu maqan yahay, ciladdu waxay ku taal dhinaca A transceiver: hal suurtagal ah waa: transceiver (TX) gudbinta indhaha dekeddu waa xun tahay sababtoo ah dekedda indhaha (RX) ee transceiver B ma helin signalka indhaha; suurtogalnimada kale waa: waxaa jira dhibaato ah xiriirka fiber this ee dekedda gudbinta indhaha ee transceiver A (TX) (fiilada indhaha ama jumper indhaha laga yaabaa in la jebiyo).
c. Tusiyaha lamaanaha qalloocan (TP) waa dansan yahay. Fadlan iska hubi in xidhiidhka lammaane ee qalloocan uu khaldan yahay ama xidhiidhku uu khaldan yahay? Fadlan isticmaal tijaabiyaha sii wadista si aad u tijaabiso (si kastaba ha ahaatee, nalalka tilmaamayaasha ee lamanaha qalloocan ee qaar ka mid ah transceivers waa in ay sugaan ilaa inta isku xirka fiberku ku xiran yahay).
d. Transceivers Qaarkood waxay leeyihiin laba dekedood oo RJ45 ah: (ToHUB) waxay tilmaamaysaa in khadka isku xidhkabeddelowaa xariiq toosan; (ToNode) waxay tilmaamaysaa in xariiqda isku xidhkabeddelowaa xariiq isdhaafsan.
e. Kordhinta timaha qaarkood waxay leeyihiin MPRbeddelodhinaca: waxay ka dhigan tahay in khadka isku xirka eebeddelowaa xariiq toosan oo toos ah; DTEbeddelo: khadka isku xirka eebeddelowaa hab isdhaafsi.
(2) Haddii fiilada indhaha iyo boodboodka fiber indhaha la jabiyay
a. Isku xirka fiilada indhaha iyo ogaanshaha goynta: isticmaal tooshka laysarka, iftiinka qoraxda, jirka iftiinka si aad u iftiimiso hal daraf ee isku xirka fiilada indhaha ama isku xidhka; bal eeg haddii uu iftiin muuqda ka jiro dhinaca kale? Haddii uu jiro iftiin muuqda, waxay muujinaysaa in xadhigga indhaha uusan jabin.
b. Ogaanshaha-off-ka ee isku xirka fiber indhaha: isticmaal tooshka laysarka, iftiinka qorraxda, iwm. bal eeg haddii uu iftiin muuqda ka jiro dhinaca kale? Haddii uu jiro iftiin muuqda, boodboodka fiberku ma jabo.
(3) Haddii qaabka kala bar/buuxa ee laba-laabka ah uu khaldan yahay
Transceivers qaarkood waxay leeyihiin FDXfurayaashadhinaca: buuxa duplex; HDXfurayaasha: laba-labo-badh.
(4) Ku tijaabi mitirka korontada indhaha
Awoodda iftiinka ah ee transceiver fiber optic ama module indhaha ee xaaladaha caadiga ah: multi-mode: inta u dhaxaysa -10db iyo -18db; hal-hab 20 kiiloomitir: inta u dhaxaysa -8db iyo -15db; hal-hab 60 kiiloomitir: inta u dhaxaysa -5db iyo -12db; Haddi awooda iftiinka fibre optic transceiver u dhexeeya -30db-45db, markaas waxaa la xukumi karaa in ay jirto dhibaato transceiver fiber optic.
