Whakaahuatanga Hua

•Ko te Fiber Optic Filter Wavelength Division Multiplexer (FWDM) e ahu mai ana i runga i te hangarau tātari kiriata angiangi-taiao.

•Ko enei taputapu ka whakakotahi, ka wehe ranei i te rama i nga roangaru rereke i roto i te awhe roangaru whanui.

•He iti rawa te mate whakaurunga, he iti te ti'aturi o te polarization, he nui te wehe me te tino pai o te taiao. Ka taea te whakatutuki i te kaha whakahaere mana nui ma te tukatuka poaka ahurei me te paninga AR kounga teitei.

•Ko enei waahanga kua whakamahia nuitia i roto i nga EDFAs, Raman amplifiers, whatunga WDM me nga taputapu whatu muka.

•Tātari Wavelength Division Multiplexer (FWDM), FWDM T1550 R1310&1490 ka taea te whakatutuki i te 1550/1310 &1490 e rua nga hongere tohu optical multiplexing me te demultiplexing.

•Ko te hanga kotahi te whakarea te kaha whakawhiti muka whatu, e whakamahia nuitia ana i roto i te whakahou whatunga muka whatu me te CATV etc.

•Ko te taputapu he iti te mate whakaurunga, te ara whatu epoxy kore utu, te ōwehenga ngaronga teitei, te tino pono me te tino pumau.

•Ara mokete: ngongo maitai, ABS pouaka modular pango.

•Ko te muka whatu kau, 0.9 mm, 2.0 mm, me te 3.0 mm Uea Whakauru/Putanga.
