Izincazelo ezimfushane
Le transmitter iyinkomba ephezulu, enemisebenzi eminingi engu-1550nm eshintshwayo ngaphakathi esezingeni eliphezulu. Yamukela i-laser ephezulu ye-DFB, enesinxephezelo esakhelwe ngaphakathi sokuhlanekezela kanye nokulawula kwe-AGC, APC, ne-ATC, okuthuthukisa kakhulu inkomba ebanzi yohlelo.
I-ST1550I uchungechunge lwe-1550nm i-optical transmitter eshintshiwe yangaphakathi iyithuluzi eliyinhloko lokwakhiwa kwamanethiwekhi okudlulisela esibili e-CATV. Isetshenziselwa ikakhulukazi izinsizakalo ze-value-added njengamasiginali wesithombe se-TV, amasiginali we-TV yedijithali, amasignali ocingo, namasignali edatha (noma idatha ecindezelweyo). Kuyisixazululo sekhwalithi ephezulu kodwa esishibhile ukuthola ukudlala kathathu kanye nezinhlelo zokudlulisa inethiwekhi ze-FTTx.
Izici Ezisebenzayo
1. Yamukela ukutshiyoza kwasekuqaleni okuphansi kanye nelaser ye-DFB ephezulu njengomthombo wesiginali.
2. Isekhethi ephelele yangaphambi kokuhlanekezela iqinisekisa ukusebenza okuphelele kwe-CTB ne-CSO ngevelu eliphezulu le-CNR.
3. Ukulawula inzuzo ezenzakalelayo (AGC) kunika amandla okukhiphayo okuzinzile kumazinga ahlukene wokufaka we-RF.
4. Amanethiwekhi ahlukene angenziwa elungiselelwe ukulungiswa kwe-OMI.
5. Ukulawula izinga lokushisa kwekesi okuzenzakalelayo ngokugcwele, abalandeli abahlakaniphile, abalandeli baqala ukusebenza lapho izinga lokushisa lekesi lifinyelela ku-30 ℃.
6. Ugesi owakhelwe ngaphakathi oyisipele okabili, ipulaki eshisayo, neswishi ezenzakalelayo kuyasekelwa.
7. Imingcele yokusebenza yomshini wonke ilawulwa yi-microprocessor kanye nokuboniswa kwesimo se-LCD kuphaneli yangaphambili kunemisebenzi eminingi efana nokuqapha isimo se-laser, ukuboniswa kwepharamitha, i-alamu yephutha, ukuphathwa kwenethiwekhi, njll.; uma amapharamitha okusebenza e-laser ephambuka ebangeni elivunyelwe elibekwe isofthiwe, uhlelo luzokhala ngokushesha.
8. Kunikezwe isixhumi esibonakalayo esijwayelekile se-RJ45, esisekela ukuphathwa kwenethiwekhi okukude ye-SNMP ne-WEB.
