Whakaahuatanga Hua

•Ko te FWDM (Focus Filter Wavelength Division Multiplexer) he mea hanga i runga i te hangarau tātari kiriata angiangi pumau mō te taiao.

•Ka whakakotahi, ka wehe rānei ēnei taputapu i te mārama i ngā roangaru rerekē i roto i te awhe roangaru whānui.

•He iti rawa te ngaronga whakaurunga, he iti te whakawhirinaki ki te porowhita, he teitei te wehenga me te pumau taiao pai rawa atu. Ka taea te whakatutuki i te kaha whakahaere mana teitei mā te tukatuka pigtail ahurei me te paninga AR kounga teitei.

•Kua whakamahia whānuitia ēnei wāhanga i roto i ngā EDFA, ngā whakakaha Raman, ngā whatunga WDM me ngā taputapu muka whatu.

•Ka taea e te FWDM T1550 R1310 me te 1490 te whakatutuki i te whakareatanga tohu whatu e rua-hongere 1550/1310 me te 1490 me te tango i ngā momo tohu whatu.

•Te hanga i te whakarea kaha tuku muka whatu kotahi, e whakamahia whānuitia ana i roto i te whakahoutanga whatunga muka whatu me te CATV me ētahi atu.

•He iti te ngaronga whakaurunga o te taputapu, he ara whatu kore-epoxy, he nui te ōwehenga memeha, he tino pono, ā, he tino pumau.

•Tikanga mōkihi: Ngongo maitai, pouaka ABS pango.

•Muka whatu tahanga, Taura Tāuru/Taputanga 0.9 mm, 2.0 mm, me te 3.0 mm.
