Dhibaatooyinka la kulma rakibaadda iyo isticmaalka fiilooyinka fiber optic
Talaabada 1: Marka hore, ma aragtaa in tusaha fiilada gudbinta ama moduleka indhaha iyo tusiyaha dekeda ee lamaanaha ah ee qalloocan ay shidaan?
1.Haddii tusaha dekedda indhaha (FX) ee transceiver-ku uu shido oo tusaha dekedda indhaha (FX) ee tusaha B transceiver-ka aanu shidnayn, cilladdu waxay ku taal dhinaca A transceiver: hal suurtagal ah waa: A transceiver (TX) gudbinta indhaha Dekeddu way jabtay sababtoo ah dekedda indhaha (RX) ee transceiver B ma hesho signalka indhaha. Suurtagalnimada kale ayaa ah in ay jirto dhibaato xiriirinta fiber-ka ee A transceiver (TX) dekedda indhaha, sida iftiinka. boodboodku wuu jabay.
2.Haddii tusaha dekedda indhaha (FX) ee transceiver uusan iftiimin, go'aami haddii isku xirka fiber-ku-xiran yahay. Jumper-ka fiber-ku wuxuu ku xiran yahay isbarbar dhig kan kalena waa isku-xiran.
3. Tusiyaha la maroojiyey (TP) ma iftiimiyo. Fadlan hubi in xadhigga lamaanaha ah ee qalloocan uu khalad yahay ama si khaldan ugu xidhan yahay. Fadlan isticmaal tijaabiyaha sii wadista si aad u hubiso.(Si kastaba ha ahaatee, qaar ka mid ah tilmaamayaasha lamaanaha qalloocan ee transceivers waa in ay sugaan ilaa isku xirka fiber-ka laga shido).
4. Qaar ka mid ah transceivers waxay leeyihiin laba dekedood oo RJ45 ah: (ToHUB) waxay tilmaamaysaa in khadka isku xirka isku xirafurayaashawaa xariiq toosan. (ToNode) waxay muujinaysaa in khadka isku xirka ee isku xirafurayaashawaa xariiqda isdhaafsan.
5. Gudbiyeyaasha qaarkood waxay leeyihiin MPRbeddelodhinaca: khadka isku xirka isku xirka ahfurayaashawaa qaab toosan oo toos ah.DTE-gabeddelo: khadka isku xirka isku xirkafurayaashawaa hab iskutallaab ah.
Talaabada 2: Falanqee in ay dhibaato ka jirto fiilada boodboodka iyo fiilada?
1.Optical fiber connection on-off detection: isticmaal tooshka laysarka, iftiinka qoraxda, iwm. si aad u iftiimiso jumper fiber-ka Haddii uu jiro iftiin muuqda, boodboodka fiberku ma jabo.
2.Cable break detection: isticmaal tooshka laysarka, iftiinka qoraxda, iftiimiye si aad u iftiimiso isku xirka fiilada ama lammaanaha. Bal eeg haddii uu jiro iftiin muuqda oo dhinaca kale ah? Haddii uu jiro iftiin muuqda, fiilada ma jabna.
Talaabada 3: Habka kala badh/buuxadu ma khaldan yahay?
Transceivers qaarkood waxay leeyihiin FDXfurayaashadhinaca: buuxa duplex; HDXfurayaasha: laba-labo-badh.
Tallaabada 4: Isticmaalka ogaanshaha qalabka mitirka korantada indhaha
Awoodda iftiinka ee transceiver indhaha ama moduleka indhaha ee xaaladaha caadiga ah: multimode: -10db-18db; hal qaab 20km: -8db–15db; hal qaab 60km: -5db–12db Haddii awooda iftiinka ee transceiver indhaha u dhexeeya -30db-45db, markaas waxaa la xukumi karaa in ay jirto dhibaato transceiver this.
Transceivers indhaha waa inay fiiro gaar ah u yeeshaan arrimaha
Si loo fududeeyo, way fiicantahay in la helo qaab su'aal iyo jawaabo, kaas oo lagu gaari karo jaleeco.
1.Does transceiver indhaha laftiisa taageertaa-duplex buuxa iyo badh-duplex?
Qaar ka mid ah chips-yada suuqa ku jira waxay isticmaali karaan oo keliya jawi laba-duplex ah hadda, mana taageeri karaan nus-duplex-ka. Haddii aad ku xirto noocyada kale eefurayaasha (DAD) ama hub (HUB), oo waxay isticmaashaa qaab laba-labo-labo ah, waxay hubaal ahaan keeni doontaa isku dhacyo halis ah iyo luminta xirmooyinka.
2.Miyaa lagu tijaabiyay isku xidhka transceivers kale fiber optic?
Waqtigan xaadirka ah, waxaa jira in badan oo ka mid ah transceivers indhaha ee suuqa. Tusaale ahaan, haddii iswaafajinta noocyada kala duwan ee transceivers aan horay loo tijaabin, waxay sidoo kale keeni doontaa luminta baakidhka, wakhti dheer oo gudbin ah, iyo degdeg ah oo gaabis ah.
3.Ma jiraa qalab badbaado oo lagaga hortagayo luminta xidhmada?
Qaar ka mid ah soosaarayaasha ayaa isticmaala habka wareejinta xogta si ay u yareeyaan kharashyada marka ay soo saarayaan fiilooyinka fiber optic. Khasaaraha ugu weyn ee habkan ayaa ah in gudbintu ay tahay mid aan degganayn oo luminta baakidhka, iyo waxa ugu fiican waa in la isticmaalo naqshadaynta khadka xajinta, taas oo si badbaado leh uga fogaan karta xogta. khasaare baakidh.
4.La qabsiga heerkulka?
Marka fibre optic transceiver laftiisa la isticmaalo, waxay dhalin doontaa kulayl sare. Marka heerkulku aad u sarreeyo (oo aan ka badnayn 50 °C), haddii fibre optic transceiver uu si caadi ah u shaqeeyo waa arrin mudan in ay tixgeliyaan macaamiisha!
5.Ma jiraa heerka IEEE802.3u?
Haddii transceiver-ka indhaha uu la kulmo heerka IEEE802.3, taas oo ah, wakhtiga daahitaanka waxaa lagu xakameynayaa 46 bits. Haddii ay dhaafto 46-bits, fogaanta uu gudbinayo qalab-beeraha indhaha waa la soo gaabin doonaa.
6.Adeegga iibka kadib:
Si loo sameeyo adeegga iibka kadib jawaab degdeg ah oo degdeg ah, waxaa lagu talinayaa in macaamiisha ay iibsadaan transceivers fiber-optic iyadoo loo eegayo xoogga soo saaraha, tignoolajiyada, sumcadda iyo shirkadaha kale.
