The optical splitter ndi chimodzi mwazinthu zofunika kungokhala chete mu ulalo wa fiber optical, ndipo makamaka amasewera gawo logawanika. Nthawi zambiri amagwiritsidwa ntchito mu optical line terminalOLTndi optical network terminalONUya passive Optical network kuti muzindikire kugawanika kwa chizindikiro.
Optical splitter amagawira chizindikiro cha kuwala mumtundu umodzi wa kuwala kupita ku ma fiber angapo. Pali mitundu yambiri yogawa, 1 × 2, 1 × 4, 1 × N, kapena 2 × 4, M × N. Kamangidwe kake ka FTTH ndi:OLT(kumapeto kwa ofesi yamakompyuta) -ODN (passive optical network distribution system)-ONU(mapeto ogwiritsira ntchito), momwe chogawaniza chowonekera chimayikidwa mu ODN kuzindikira kuti ogwiritsa ntchito angapo amagawana mawonekedwe amodzi a PON. Mu dongosolo la PON, pamene kugawa kwa nyumba kumabalalika komanso kosasinthika, monga kugawa kwa nyumba zosungiramo nyumba, mtunda uli kutali, ndipo kachulukidwe ka ogwiritsa ntchito ndi otsika, njira yogawanitsa yapakati ingagwiritse ntchito mokwanira zinthu ndikuphimba zozungulira.
Chogawanitsa chimodzi chokha cha kuwala chingagwiritsidwe ntchito mu network passive Optical, kapena ma splitter angapo atha kugwiritsidwa ntchito palimodzi kugawa ma siginecha a kuwala.
Zizindikiro zomwe zimakhudza optical splitter nthawi zambiri ndi izi:
Kutayika kolowetsa
Kutayika kwa kuyika kwa fiber splitter kumatanthawuza kuchuluka kwa dB pazotulutsa zilizonse zokhudzana ndi kutayika kwa kuwala. Nthawi zambiri, chocheperako chotayika mtengo.
Chigawo chogawanika
Chiŵerengero chogawanika chimatanthauzidwa ngati chiŵerengero cha mphamvu zotuluka pa doko lililonse lotulutsa fiber splitter. Nthawi zambiri, chiŵerengero chogawanika cha PLC Optical splitter chimagawidwa mofanana, ndipo chiŵerengero chogawanika cha osakaniza tapered optical splitter chikhoza kukhala chosiyana. Chiŵerengero chapadera cha chiŵerengero chogawanika chimagwirizana ndi kutalika kwa kuwala kwa kuwala kofalitsidwa. Mwachitsanzo, pamene nthambi ya kuwala imatumiza kuwala kwa 1.31 micron, chiŵerengero chogawanika cha mapeto awiriwa ndi 50:50; potumiza 1.5μm kuwala, kumakhala 70: 30 (Chifukwa chake izi zimachitika chifukwa chakuti fiber splitter ili ndi bandwidth inayake, ndiko kuti, bandwidth ya chizindikiro cha kuwala chomwe chimafalitsidwa pamene chiŵerengero chogawanika sichinasinthe).
Kudzipatula
Kudzipatula kumatanthauza kudzipatula kwa njira imodzi ya kuwala kwa fiber splitter kuchokera ku ma siginecha owoneka munjira zina.
Bwererani kutaya
Kutaya kubweza, komwe kumatchedwanso kutayika kwa chiwonetsero, kumatanthawuza kutayika kwa mphamvu kwa siginecha ya kuwala yomwe yabwezedwa kapena kuwonetseredwa ndi kutha kwa fiber kapena chingwe chotumizira. Kutayika kwakukulu kobwerera, ndibwino, kuchepetsa mphamvu ya kuwala kowonekera pa gwero la kuwala ndi dongosolo.
Kuonjezera apo, kufanana, kuwongolera, kutayika kwa PDL polarization, ndi zina zotero ndizonso zomwe zimakhudza ntchito ya optical splitter. Optical CHIKWANGWANI ziboda ndi imodzi mwa zipangizo zofunika kungokhala chete mu ulalo CHIKWANGWANI, ndipo makamaka oyenera kulumikiza MDF ndi zida terminal mu kungokhala chete kuwala maukonde (EPON, GPON, BPON, FTTX, FTTH, etc.) kugawira zizindikiro kuwala.
