Mfundo Zothandiza Zokhudza Kusankha Chingwe Choyenera
Kusiyana kwa Mtengo Pakati pa Zingwe za Multi-Mode ndi Single-Mode
Mtengo umakhala ndi gawo lofunika kwambiri posankha pakati pa zingwe za multimode ndi single-mode. Zingwe za multi-mode nthawi zambiri zimakhala zotsika mtengo kwambiri chifukwa cha njira yosavuta yopangira komanso kugwiritsa ntchito ma transceiver otsika mtengo. Izi zimapangitsa kuti zikhale zosankhidwa kwambiri pa ntchito zakutali, monga mkati mwa malo osungira deta kapena ma network aku campus. Komabe, chingwe cha single mode fiber optic, ngakhale poyamba chimakhala chokwera mtengo, chimapereka ndalama zogwirira ntchito kwa nthawi yayitali. Kutha kwake kuthandizira bandwidth yayikulu komanso mtunda wautali kumachepetsa kufunikira kokonzanso pafupipafupi kapena ndalama zina zowonjezera zomangamanga. Mabungwe omwe amaika patsogolo kukula ndi kutsimikizira mtsogolo nthawi zambiri amapeza kuti mtengo woyambira wa zingwe za single-mode ndi wofunika.
Kugwiritsa Ntchito Chingwe cha Single Mode Fiber Optic ndi Zingwe za Multi-Mode
Kugwiritsa ntchito zingwezi kumasiyana malinga ndi luso lawo laukadaulo. Zingwe za fiber optic za single mode ndizoyenera kulumikizana patali, monga m'malo olumikizirana mauthenga ndi malo osungira deta othamanga kwambiri. Zimasunga umphumphu wa ma signal pamtunda wokwana makilomita 200, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito ma netiweki amsana ndi ma bandwidth apamwamba. Kumbali inayi,zingwe zama mode ambiri, makamaka mitundu ya OM3 ndi OM4, ndi yabwino kwambiri kuti igwiritsidwe ntchito patali. Nthawi zambiri imagwiritsidwa ntchito m'ma netiweki achinsinsi ndi malo osungira deta, zomwe zimathandiza kuti deta ifike pa 10Gbps patali pang'ono. Kukula kwake kwakukulu kwa pakatikati kumalola kutumiza deta bwino m'malo omwe ntchito yakutali sikufunika.
Kugwirizana ndi Zomangamanga za Network zomwe zilipo
Kugwirizana ndi zomangamanga zomwe zilipo ndi chinthu china chofunikira kwambiri. Zingwe zamitundu yambiri nthawi zambiri zimagwiritsidwa ntchito m'makina akale komwe kumafunika kukweza kotsika mtengo. Kugwirizana kwawo ndi ma transceiver akale ndi zida kumawapangitsa kukhala chisankho chabwino chosungira ma netiweki omwe alipo. Komabe, chingwe cha fiber optic cha single mode ndi choyenera kwambiri pa ma netiweki amakono komanso ogwira ntchito kwambiri. Kutha kwake kulumikizana ndi ma transceiver apamwamba ndikuthandizira kuchuluka kwa data kumatsimikizira kugwira ntchito bwino m'malo amakono. Pokweza kapena kusintha, mabungwe ayenera kuwunika zomangamanga zawo zomwe zilipo kuti adziwe mtundu wa chingwe womwe ukugwirizana ndi zolinga zawo zogwirira ntchito.
Kusintha kapena Kusintha Pakati pa Multi-Mode ndi Single-Mode
Kugwiritsa Ntchito Ma Transceiver Kuti Agwirizane
Ma transceiver amagwira ntchito yofunika kwambiri potseka kusiyana pakati pa zingwe za multi-mode ndi single-mode. Zipangizozi zimasintha ma siginolo kuti zitsimikizire kuti zikugwirizana pakati pa mitundu yosiyanasiyana ya ulusi, zomwe zimathandiza kuti kulumikizana kukhale kosasunthika mkati mwa ma network osakanikirana. Mwachitsanzo, ma transceiver monga SFP, SFP+, ndi QSFP28 amapereka kuchuluka kosiyanasiyana kwa kusamutsa deta, kuyambira 1 Gbps mpaka 100 Gbps, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito monga ma LAN, malo osungira deta, ndi makompyuta ogwira ntchito bwino.
| Mtundu wa Transceiver | Mtengo Wosamutsa Deta | Mapulogalamu Odziwika |
