Iyo imishinga idahwitse ihuye nintera ndende, fibre optique ikoreshwa. Kuberako intera yoherejwe ya fibre optique ari ndende cyane, muri rusange, intera yoherejwe ya fibre imwe ya fibre imwe irenga kilometero 10, kandi intera yoherejwe ya fibre yuburyo bwinshi irashobora kugera kuri kilometero 2.
Mumiyoboro ya fibre optique, dukunze gukoresha fibre optique. None, nigute ushobora guhuza fibre optique? Reka turebere hamwe.
Ubwa mbere, uruhare rwa fibre optique
Trans optique ya fibre optique irashobora kwagura intera yoherejwe na Ethernet no kwagura radiyo ya Ethernet.
② Amashanyarazi ya fibre optique arashoborahindurahagati ya 10M, 100M cyangwa 1000M Ethernet y'amashanyarazi na optique.
③ Gukoresha fibre optique kugirango wubake umuyoboro urashobora kuzigama ishoramari.
Fiber Amashanyarazi ya fibre optique akora imikoranire hagati ya seriveri, abisubiramo, hubs, terminal hamwe na terminal byihuse.
Trans optique ya fibre optique ifite microprocessor hamwe ninteruro yo gusuzuma, ishobora gutanga amakuru atandukanye ahuza amakuru yimikorere.
Icya kabiri, niyihe transceiver optique ihindura kandi niyihe yakira?
Iyo ukoresheje fibre optique, inshuti nyinshi zizahura nibibazo nkibi:
1.Ese optique ya fibre optique igomba gukoreshwa kubiri?
2.Ese optique ya fibre optique igabanijwemo imwe yo kwakira niyindi yohereza? Cyangwa hashobora gukoreshwa gusa transiteri ebyiri gusa?
3. Niba optique ya fibre optique igomba gukoreshwa kubiri, birakenewe ko bahuje ikirango nicyitegererezo? Cyangwa ibirango ibyo aribyo byose birashobora gukoreshwa hamwe?
Igisubizo: Amashanyarazi ya fibre optique akoreshwa muburyo bubiri nkibikoresho byo guhindura amafoto, ariko biranashoboka guhuza fibre optique hamwe na fibreGuhindura, fibre optique ya transfert na SFP. Ihame, mugihe cyose optique yoherejwe yoherejwe nuburebure buringaniye Imiterere ya signal encapsulation ni imwe kandi byombi bishyigikira protocole runaka kugirango ugere kuri fibre optique.
Mubisanzwe, uburyo bumwe-bubiri-fibre (fibre ebyiri zirakenewe kugirango itumanaho risanzwe) transcevers ntabwo igabanijwe kumpera yohereza no kurangiza, kandi irashobora gukoreshwa igihe cyose igaragara muri babiri.
Gusa fibre transceiver imwe (fibre imwe irakenewe kugirango itumanaho risanzwe) izagira ihererekanyabubasha kandi iherezo ryakira.
Muyandi magambo, ibipimo bitandukanye (100M na Gigabit) hamwe nuburebure butandukanye (1310nm na 1300nm) ntibishobora kuvugana. Mubyongeyeho, niyo fibre transceiver imwe hamwe na fibre ebyiri yibirango bimwe byahujwe, ntibishoboka kuvugana. Imikoranire.
Ikibazo rero ni iki, transceiver imwe ya fibre imwe niki kandi ikwirakwiza fibre ebyiri? Ni irihe tandukaniro riri hagati yabo?
Transceiver imwe ya fibre imwe ni iki? Transibiver ya fibre ebyiri ni iki?
Imiyoboro imwe ya fibre yerekana uburyo bumwe bwa optique ya optique. Transceiver imwe ya fibre ikoresha intangiriro imwe gusa kandi impande zombi zahujwe niyi nkingi. Transceivers kumpera zombi zikoresha optique yumurongo utandukanye, kuburyo zishobora kwanduzwa mukimenyetso kimwe cyumucyo.
Ikwirakwizwa rya fibre fibre ikoresha ibice bibiri, imwe yo kohereza hamwe niyakirwa, kandi impera imwe igomba kwinjizwa kurundi ruhande, kandi impande zombi zigomba kwambuka.
1.Single fibre transceiver
Umuyoboro umwe wa fibre ugomba gushyira mubikorwa ibikorwa byohereza no kwakira ibikorwa. Ikoresha umurongo wigice cyogukwirakwiza tekinoroji yohereza no kwakira ibimenyetso bibiri bya optique hamwe nuburebure butandukanye kuri fibre optique.
Kubwibyo, uburyo bumwe bumwe bwa fibre transceiver yanduzwa binyuze muri fibre optique, bityo urumuri rwohereza no kwakira rwanduzwa binyuze muri fibre icyarimwe. Muri iki kibazo, kugirango ugere ku itumanaho risanzwe, uburebure bubiri bwumucyo bugomba gukoreshwa kugirango butandukanye.
Kubwibyo, optique ya module yuburyo bumwe bumwe bwa fibre transceiver ifite uburebure bubiri bwumucyo wasohotse, mubisanzwe 1310nm / 1550nm. Muri ubu buryo, hari itandukaniro hagati yimpera zombi zimpande zombi:
Transceiver kumpera imwe yohereza 1310nm kandi yakira 1550nm.
Iyindi mpera isohora 1550nm ikakira 1310nm.
Biroroshye rero kubakoresha gutandukanya, kandi muri rusange bakoresha inyuguti aho.
A-terminal (1310nm / 1550nm) na B-terminal (1550nm / 1310nm) byagaragaye.
Abakoresha bagomba gukoresha AB guhuza, ntabwo AA cyangwa BB ihuza.
AB iherezo rikoreshwa gusa kuri fibre optique.
2. Transibiver ya fibre ebyiri
Ikwirakwizwa rya fibre fibre ifite icyambu cya TX (icyambu cyohereza) hamwe nicyambu cya RX (icyambu cyakira). Ibyambu byombi byohereza ku burebure bumwe bwa 1310nm, kandi no kwakira ni 1310nm. Kubwibyo, fibre ebyiri zibangikanye zikoreshwa mugukoresha insinga zirahujwe.
3. Nigute dushobora gutandukanya insimburangingo imwe ya fibre transibiver?
Kuri ubu hariho uburyo bubiri bwo gutandukanya insimburangingo imwe ya fibre itandukanye.
HenIyo optique ya optique yashizwemo na module optique, transceiver ya optique igabanijwemo fibre imwe ya fibre hamwe na transibiri ya fibre ikurikije umubare wa cores ya optique ya fibre ihuza. Umurongo wa fibre optique usimbuka uhujwe na fibre transibre imwe (iburyo) ni fibre yibanze, ishinzwe kohereza no kwakira amakuru; Umurongo ni ibice bibiri. Intangiriro imwe ishinzwe kohereza amakuru naho ubundi intangiriro ishinzwe kwakira amakuru.
HenIyo optique ya fibre optique idafite module ya optique yashyizwemo, birakenewe gutandukanya fibre imwe ya fibre transceiver hamwe na fibre ebyiri ya fibre ukurikije module yashizwemo. Iyo module imwe ya fibre optique module yinjijwe muri optique ya fibre optique, ni ukuvuga, intera ni ubwoko bworoshye, fibre optique ni fibre imwe (ishusho iburyo); iyo module ya fibre ebyiri-fibre optique yinjijwe muri optique ya fibre optique, Nukuvuga ko, iyo intera ari ubwoko bwa duplex, iyi transceiver ni fibre-fibre (ishusho yibumoso).
Icya kane, icyerekezo no guhuza optique fibre transceiver
1.Icyerekezo cya optique fibre transceiver
Kubyerekana icyerekezo cya fibre optique, dufite ingingo yabanjirije iyi ibirimo.
Hano twongeye gusubiramo dukoresheje ishusho kugirango byumvikane neza.
2.Ihuza rya fibre optique
