Mavuto omwe amakumana nawo pakuyika ndi kugwiritsa ntchito ma transceivers a fiber optic
Khwerero 1: Choyamba, kodi mukuwona ngati chizindikiro cha fiber transceiver kapena optical module ndi chizindikiro cha doko chopindika chilipo?
1.Ngati chizindikiro cha kuwala (FX) cha A transceiver chilipo ndipo chizindikiro cha optical port (FX) cha B transceiver sichiyatsidwa, cholakwikacho chili kumbali ya A transceiver: zotheka chimodzi ndi: Transceiver (TX) kutumiza kwa optical Doko lathyoka chifukwa doko la optical (RX) la B transceiver sililandira chizindikiro cha kuwala.Njira ina ndi yakuti pali vuto ndi chingwe ichi cha fiber cha A transceiver (TX) optical port, monga kuwala. jumper yathyoka.
2.Ngati chizindikiro cha optical port (FX) cha transceiver sichiunikira, dziwani ngati chingwe cha fiber chikugwirizanitsa.Fiber jumper imalumikizidwa molumikizana ndipo inayo ndi yolumikizira.
3.Chizindikiro chopotoka (TP) sichiwala.Chonde onetsetsani kuti chingwe chopindika ndicholakwika kapena cholumikizidwa molakwika.Chonde gwiritsani ntchito continuity tester kuti muwone.(Komabe, zizindikiro zina zopotoka za transceivers ziyenera kudikirira mpaka ulalo wa ulusi utatsegulidwa).
4.Ma transceivers ena ali ndi ma doko awiri a RJ45: (ToHUB) akuwonetsa kuti mzere wolumikizana womwe umalumikiza masinthidwe ndi mzere wowongoka.(ToNode) ikuwonetsa kuti chingwe cholumikizira cholumikizira masiwichi ndi mzere wodutsa.
5.Ma transmitters ena ali ndi kusintha kwa MPR kumbali: mzere wogwirizanitsa wogwirizanitsa kusinthako ndi njira yowongoka.
Khwerero 2: Unikani ngati pali vuto ndi fiber jumper ndi chingwe?
1.Optical fiber connection pa-off kuzindikira: gwiritsani ntchito nyali ya laser, kuwala kwa dzuwa, ndi zina zotero kuti muwunikire fiber jumper.Kuwona ngati pali kuwala kowonekera kumbali inayo?Ngati pali kuwala kowoneka, fiber jumper sidasweka.
2.Kuzindikira kwachingwe: gwiritsani ntchito tochi ya laser, kuwala kwa dzuwa, chowunikira kuti muwunikire cholumikizira chingwe kapena coupler.Kuwona ngati pali kuwala kowoneka kumbali inayo?Ngati pali kuwala kowonekera, chingwecho sichimasweka.
Khwerero 3: Kodi njira ya theka/full duplex ndiyolakwika?
Ma transceivers ena ali ndi masiwichi a FDX kumbali: duplex yodzaza;Kusintha kwa HDX: theka la duplex.
Khwerero 4: Kugwiritsa ntchito zida zowunikira zamagetsi zamagetsi
Mphamvu yowala ya transceiver optical kapena optical module pansi pazikhalidwe zachilendo: multimode: -10db-18db;single mode 20km: -8db–15db;single mode 60km: -5db-12db Ngati mphamvu yowala ya transceiver ya kuwala ili pakati pa -30db-45db, ndiye kuti ikhoza kuweruzidwa kuti pali vuto ndi transceiver iyi.
Ma transceivers owoneka ayenera kulabadira zinthu
Pofuna kuphweka, ndi bwino kukhala ndi kalembedwe ka mafunso ndi mayankho, omwe angapezeke pang'onopang'ono.
1.Kodi transceiver ya kuwala yokha imathandizira full-duplex ndi theka-duplex?
Tchipisi zina pamsika zitha kugwiritsa ntchito malo okhala ndi duplex pakadali pano, ndipo sangathe kuthandizira theka-duplex.Ngati mungalumikizane ndi masiwichi ena (SWITCH) kapena hub (HUB), ndipo imagwiritsa ntchito mawonekedwe a theka-duplex, zidzayambitsa mikangano yayikulu komanso kutayika kwa paketi.
2.Kodi yayesedwa kuti igwirizane ndi ma transceivers ena a fiber optic?
Pakali pano, pali ma transceivers ochulukirachulukira pamsika.Mwachitsanzo, ngati kugwirizana kwa mitundu yosiyanasiyana ya ma transceivers sikunayesedwe kale, kungayambitsenso kutayika kwa paketi, nthawi yayitali yotumizira, komanso mofulumira komanso pang'onopang'ono.
3.Kodi pali chida chachitetezo choteteza kutayika kwa paketi?
Opanga ena amagwiritsa ntchito njira yotumizira deta kuti achepetse ndalama popanga ma transceivers opangidwa ndi fiber optic.Choyipa chachikulu cha njirayi ndikuti kufalitsa kumakhala kosakhazikika komanso kutayika kwa paketi, ndipo zabwino kwambiri ndikugwiritsa ntchito kapangidwe ka mzere wa buffer, womwe ungapeweretu deta. kutayika kwa paketi.
4.Kusinthasintha kwa kutentha?
Pamene fiber optic transceiver ikagwiritsidwa ntchito, imatulutsa kutentha kwakukulu.Kutentha kukakhala kokwera kwambiri (osapitirira 50 ° C), kaya fiber optic transceiver imagwira ntchito nthawi zonse ndi chinthu choyenera kuganizira ndi makasitomala!
5.Kodi pali muyezo wa IEEE802.3u?
Ngati transceiver ya kuwala ikukumana ndi muyezo wa IEEE802.3, ndiye kuti, nthawi yochedwa imayendetsedwa pa 46 bits.Ngati ipitilira ma bits 46, mtunda womwe umaperekedwa ndi transceiver ya kuwala udzafupikitsidwa.
6.After-sales service:
Pofuna kuti ntchito yogulitsa pambuyo pogulitsa iyankhe mwamsanga komanso mofulumira, tikulimbikitsidwa kuti makasitomala agule ma transceivers a fiber-optic malinga ndi mphamvu ya wopanga, teknoloji, mbiri ndi makampani ena.
