Ibibazo byahuye nabyo mugushiraho no gukoresha fibre optique
Intambwe ya 1: Icya mbere, urabona niba icyerekezo cya fibre transceiver cyangwa module ya optique hamwe nicyerekezo cya port cyerekanwe kiri kuri?
1.Niba icyerekezo cya optique (FX) cyerekana A transceiver kiri kandi icyambu cya optique (FX) cyerekana B transceiver ntigicanwa, ikosa riri kuruhande rwa transceiver: ikintu kimwe gishoboka ni: Transceiver (TX) ihererekanyabubasha Icyambu cyacitse kubera ko icyambu cya optique (RX) cya B transceiver kitakira ibimenyetso bya optique. Ikindi gishoboka ni uko hari ikibazo kijyanye niyi fibre ihuza icyambu cya A transceiver (TX), nkumucyo gusimbuka.
2.Niba icyerekezo cya optique (FX) cyerekana transceiver kitamurika, menya niba fibre ihuza. Fiber jumper ihujwe murwego rumwe naho ubundi ni ihuriro.
3.Icyerekezo kigoretse (TP) ntigaragaza. Nyamuneka reba neza ko umugozi wahinduwe wagizwe amakosa cyangwa uhujwe nabi. Nyamuneka koresha ibizamini bikomeza kugirango ugenzure.
4.Bamwe mu barenga bafite ibyambu bibiri bya RJ45: (ToHUB) byerekana ko umurongo uhuza uhuzaGuhindurani umurongo ugororotse. (ToNode) yerekana ko umurongo uhuza uhuzaGuhindurani umurongo.
5.Bohereza bamwe bafite MPRhindurakuruhande: umurongo uhuza uhuzaGuhindurani umurongo ugororotse unyuze kumurongo. DTEhindura: umurongo uhuza uhuzaGuhindurani i Imirongo.
Intambwe ya 2: Gisesengura niba hari ikibazo kijyanye na fibre jumper na kabel?
1.Ibikoresho bya fibre optique on-off detection: koresha urumuri rwa laser, urumuri rwizuba, nibindi kugirango umurikire fibre.Reba niba hari urumuri rugaragara kurundi ruhande? Niba hari urumuri rugaragara, gusimbuka fibre ntabwo byacitse.
2.Cable break detection: koresha urumuri rwa laser, urumuri rwizuba, rumurika kugirango umurikire umugozi cyangwa coupler. Reba niba hari urumuri rugaragara kurundi ruhande? Niba hari urumuri rugaragara, umugozi ntucika.
Intambwe ya 3: Igice cya / cyuzuye duplex nuburyo butari bwo?
Transcevers zimwe zifite FDXGuhindurakuruhande: duplex yuzuye; HDXGuhindura: igice cya kabiri.
Intambwe ya 4: Gukoresha ibikoresho bya metero ya optique
Imbaraga zumucyo za optique ya optique cyangwa module ya optique mubihe bisanzwe: multimode: -10db - 18db; uburyo bumwe 20km: -8db - 15db; uburyo bumwe 60km: -5db - 12db Niba imbaraga zumucyo za optique ya optique iri hagati ya -30db - 45db, noneho birashobora kugaragara ko hari ikibazo cyiyi transceiver.
Amashanyarazi meza agomba kwitondera ibibazo
Kugirango byorohe, nibyiza kugira ikibazo nibisubizo byuburyo, bishobora kugerwaho ukireba.
1.Ese optique ya optique ubwayo ishyigikira byuzuye-duplex na kimwe cya kabiri?
Amashanyarazi amwe kumasoko arashobora gukoresha gusa ibidukikije byuzuye muri iki gihe, kandi ntibishobora gushyigikira kimwe cya kabiri. Niba uhuza nibindi birango byaGuhindura (SWITCH) cyangwa hub (HUB), kandi ikoresha igice cya duplex, byanze bikunze bizatera amakimbirane akomeye no gutakaza paki.
2.Yigeze igeragezwa kugirango ihuze nizindi fibre optique?
Kugeza ubu, hari byinshi kandi byinshi byohereza ibicuruzwa ku isoko. Kurugero, niba guhuza ibirango bitandukanye bya transceivers bitigeze bigeragezwa mbere, bizavamo no gutakaza paki, igihe kinini cyo kohereza, kandi byihuse kandi bitinda.
3.Hariho igikoresho cyumutekano kugirango wirinde gutakaza paki?
Bamwe mu bakora inganda bakoresha uburyo bwo kohereza amakuru kugirango bagabanye ibiciro mugihe bakora fibre optique transcevers.Ikibi gikomeye cyubu buryo nuko ihererekanyabubasha ridahungabana kandi ryatakaye, kandi ibyiza ni ugukoresha igishushanyo mbonera, gishobora kwirinda amakuru neza gutakaza paki.
4. Guhuza n'imihindagurikire y'ikirere?
Iyo fibre optique transceiver ubwayo yakoreshejwe, izabyara ubushyuhe bwinshi. Iyo ubushyuhe buri hejuru (ntiburenze 50 ° C), niba fibre optique transceiver ikora mubisanzwe nikintu gikwiye gusuzumwa nabakiriya!
5.Hariho IEEE802.3u isanzwe?
Niba optique ya optique yujuje ubuziranenge bwa IEEE802.3, ni ukuvuga ko gutinda kugenzurwa kuri 46 bit. Niba irenze 46 bits, intera yoherejwe na optique transceiver izagabanywa.
6.Nyuma yo kugurisha:
Kugirango serivisi nyuma yo kugurisha isubizwe vuba na kare, birasabwa ko abakiriya bagura transibre ya fibre optique bakurikije imbaraga zuwabikoze, ikoranabuhanga, izina ndetse nandi masosiyete.
