Kweli nqaku ndiza kuthetha malunga nokuba yintoni ebangela ilahleko kuthumelo lwefiber optics. Masifunde...
Isizathu sokuba kutheni i-fiber optical ithatha indawo yosasazo oluphakathi kunye nomgama omde weentambo zenethiwekhi kungenxa yokuba ukuhanjiswa kwe-fiber optical kunelahleko ephantsi, kwaye ilahleko yayo yahlulwe ngokulandelayo:
Ukulahlekelwa kukulahlekelwa kwamandla okukhanya okubangelwa ukuxutywa, ukusabalalisa kunye nokuvuza kwe-medium (umoya) xa ukukhanya kuhanjiswa kwi-fiber optical (i-fiber optical ayikwazi ukuhlukanisa ngokupheleleyo ukukhanya, okuya kubangela ukuvuza kokukhanya). Ilahleko yale nxalenye yamandla iyanda ngomgama wothumelo. Ukunyuka kuchithwa kwinqanaba elithile.
Umzekelo: Imodyuli ye-1310nm ye-optical ibala ilahleko yokuhanjiswa kwekhonkco kwi-0.35dBm/km,
Imodyuli ye-1550nm ye-optical ibala ilahleko yokuhanjiswa kwekhonkco kwi-0.20dBm / km.Kwaye le lahleko iya kuchaphazeleka ngamaxabiso ahlukeneyo, kwaye ukulahleka kokuhanjiswa kwekhonkco kuhambelana nezinga.
Ukusasazwa ikakhulu kubangelwa kukuba amaza ombane ombane ohlukeneyo obude bamaza ahamba kwindawo enye ngesantya esahlukileyo, nto leyo ekhokelela kwiinxalenye ezahlukeneyo zamaza ophawu lokukhanya ezifika kwindawo yokwamkela ngamaxesha ahlukeneyo ngenxa yokuqokelelwa kwemigama yothumelo, okukhokelela kwi-pulse. ukwandisa kunye nokungakwazi ukwahlula umqondiso. ixabiso. Ukubalwa kwexabiso lokusasazwa kunzima kakhulu kwaye ngokuqhelekileyo kubhekiselwa kuphela.
Ukulahleka kokufakwa, ngokude nje ukuba i-interface iphela kwi-fiber optical ifakwe, ingavalwanga ngokupheleleyo, okubangelwa ukuvuza kokukhanya kunye nezinye izinto, okubangelwa ukulahlekelwa kokufakwa. Ngokuqhelekileyo, ilahleko yokufaka iphakathi kwe-0.15-0.35dbm.
Oku ngasentla yinkcazo yolwazi olulahlekileyo lwe-optical fiber transmission eziswe yi-Shenzhen HDV photoelectric Technology Co., Ltd. Iimveliso zemodyuli eziveliswe yikhava yenkampani. iimodyuli zefiber optical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl. Ezi mveliso zemodyuli zingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi. Iqela le-R&D elinobuchule kunye nelomeleleyo linokunceda abathengi abanemiba yobugcisa, kwaye iqela leshishini elicingayo nelinobuchule linokunceda abathengi bafumane iinkonzo ezikumgangatho ophezulu ngexesha lokubonisana kwangaphambili kunye nomsebenzi wasemva kokuvelisa. Wamkelekile kuwe Qhagamshelana nathi kulo naluphi na uhlobo lombuzo.
