Isiguquli se-photoelectric singathuthukisa ngokushelela i-Ethernet yasekuqaleni esheshayo futhi sivikele ngokugcwele izinsiza zenethiwekhi zangempela zomsebenzisi.Ingase futhi ibizwe ngokuthi i-optical fiber transceiver.Isiguquli se-photoelectric singabona ukuxhumana phakathi kweswishi nekhompyutha, singasetshenziswa futhi njengesidluliseli sokudlulisa, futhi singenza ukuguqulwa kwemodi eyodwa enemodi eminingi.Phakathi nenqubo yokufaka isicelo se-transceiver ye-fiber optical, kufanele kuqashelwe ukuyigcina, ukuze kwandiswe impilo yesevisi yomshini.
Uyini umsebenzi wesiguquli se-photoelectric?
1. Isiguquli se-photoelectric asikwazi nje ukubona ukuxhumana phakathi kweswishi nesishintshi, kodwa futhi ukuxhumana phakathi kweswishi nekhompyutha, kanye nokuxhumana phakathi kwekhompyutha nekhompyutha.
2. I-Transfer relay, lapho ibanga langempela lokudlulisela lidlula ibanga elivamile lokudluliswa kwe-transceiver, ikakhulukazi uma ibanga langempela lokudlulisela lidlula i-120Km, uma izimo zesayithi zivuma, sebenzisa ama-transceivers angu-2 ngokudlulisela emuva kuya emuva noma sebenzisa ukukhanya- Iziguquli ze-Optical. ngoba ukudlulisa kuyisixazululo esingabizi kakhulu.
3. Ukuguqulwa kwemodi eyodwa enemodi eminingi.Uma uxhumano lwe-fiber yemodi eyodwa-multi-mode ludingeka phakathi kwamanethiwekhi, isiguquli semodi eyodwa-multi-mode singasetshenziswa ukuxhuma, okuxazulula inkinga yokuguqulwa kwe-fiber yemodi eyodwa-multi-mode.
4. Ukudluliselwa kwe-wavelength division multiplexing.Lapho izinsiza zekhebula le-fiber optical ebangeni elide zinganele, ukuze kwandiswe izinga lokusebenzisa ikhebula lokukhanya nokunciphisa izindleko, i-transceiver kanye ne-multiplexer ye-wavelength division ingasetshenziswa ndawonye ukuze kudluliselwe iziteshi ezimbili zolwazi ngepheya efanayo. imicu ye-optical.
Ungayigcina kanjani i-fiber optic transceiver?
1. Ekusetshenzisweni kwe-fiber optic transceivers, kuyadingeka ukuqinisekisa ukuthi izingxenye ze-laser kanye namamojula okuguqulwa kwe-photoelectric we-transceiver optical aqhutshwa ngokuqhubekayo futhi ajwayelekile, futhi umthelela we-pulse current osheshayo uyagwenywa, ngakho-ke akufanelekanga shintsha umshini njalo.Igumbi lekhompiyutha eliphambili elimaphakathi lapho kugxilwe khona ama-transceiver optical kanye nephoyinti lesethi ye-1550nm optical transmitter optical amplifier kufanele ifakwe amandla kagesi we-UPS ukuvikela izingxenye ze-laser nokuvimbela imojula yokuguqula isithombe kagesi ukuthi ingalinyazwa ukushaya kwenhliziyo okuphezulu.
2. Indawo yokusebenza enomoya, ekhipha ukushisa, efaka umswakama, futhi icocekile kufanele igcinwe ngesikhathi kusetshenziswa ama-transceivers e-fiber optic??Ingxenye ye-laser ye-optical transmitter iyinhliziyo yemishini futhi idinga izimo zokusebenza eziphezulu.Ukuze kuqinisekiswe ukusebenza okuvamile kwemishini, umenzi we-A isiqandisi kanye nesistimu yokwenqatshwa kokushisa ifakwe kumishini, kodwa lapho izinga lokushisa elizungezile lidlula ububanzi obuvunyelwe, okokusebenza akukwazi ukusebenza ngokujwayelekile.Ngakho-ke, ngenkathi eshisayo, lapho igumbi lekhompiyutha eliphakathi linemishini eminingi yokushisa kanye nezimo ezimbi zokuphefumula kanye nezimo zokushisa ukushisa, kungcono ukufaka uhlelo lwe-Air conditioning ukuqinisekisa ukusebenza okuvamile kwe-transceiver optical.I-diameter esebenzayo ye-fiber core isezingeni le-micron.Uthuli oluncane olungena ku-interface esebenzayo ye-pigtail luzovimbela ukusakazeka kwamasignali optical, okubangela ukwehla okuphawulekayo kwamandla optical kanye nokunciphisa isilinganiso sesignali-kuya-umsindo wesistimu.Lolu hlobo lwezinga lokuhluleka lungaba ngu-50%, ngakho igumbi lekhompyutha Ukuhlanzeka nakho kubaluleke kakhulu.
3. Ukusetshenziswa kwe-fiber optic transceivers kumele kuqashelwe futhi kuqoshwe.I-transceiver ebonakalayo ifakwe i-microprocessor ukuqapha isimo sangaphakathi sokusebenza sohlelo futhi iqoqe imingcele ehlukahlukene yokusebenza yemodyuli, futhi ibonise ngokubonakalayo ngohlelo lokubonisa lwe-LED ne-VFD, ukuze kukhumbuze inani ngesikhathi Kubasebenzi, i-optical transmitter ifakwe i-alamu ezwakalayo futhi ebonakalayo.Uma nje abasebenzi besondlo benquma imbangela yephutha ngokusho kwemingcele yokusebenza futhi babhekane nayo ngesikhathi, ukusebenza okuvamile kwesistimu kungaqinisekiswa.
