Chidziwitso: 1. Kusintha kwa zinthu kulipo.
2. Yatchulidwa popanda cholumikizira, ndipo onjezerani kutayika kwina kwa 0.2dB pa cholumikizira chilichonse.
Mafotokozedwe Akatundu
•Fiber Optic Filter Wavelength Division Multiplexer (FWDM) imachokera ku ukadaulo wofewetsa filimu yopyapyala yokhazikika pa chilengedwe.
•Zipangizozi zimaphatikiza kapena kulekanitsa kuwala pa mafunde osiyanasiyana pa mafunde ambiri.
•Amapereka kutayika kochepa kwambiri kwa ma insertion, kudalira pang'ono kwa polarization, kudzipatula kwakukulu komanso kukhazikika kwabwino kwa chilengedwe. Kutha kugwira ntchito mwamphamvu kwambiri kumatha kuchitika kudzera mu kukonza kwapadera kwa pigtail ndi AR coating yapamwamba kwambiri.
•Zigawozi zagwiritsidwa ntchito kwambiri mu EDFAs, Raman amplifiers, WDM networks ndi fiber optical instruments.
•Filter Wavelength Division Multiplexer (FWDM), FWDM T1550 R1310 & 1490 ikhoza kukwaniritsa 1550/1310 & 1490 two channel optical signal multiplexing ndi demultiplexing.
•Kupanga chochulukitsa mphamvu ya single optical fiber transmission, chomwe chimagwiritsidwa ntchito kwambiri pakukweza maukonde a fiber optical ndi CATV etc.
•Chipangizochi chili ndi kutayika kochepa kwa kuyika, njira yowunikira yopanda epoxy, chiŵerengero chachikulu cha kutha kwa zinthu, kudalirika kwambiri komanso kukhazikika kwakukulu.
•Njira yopangira phukusi: Chubu chachitsulo, bokosi lakuda la ABS.
•Ulusi wopanda kuwala, Chingwe Cholowera/Chotulutsa cha 0.9 mm, 2.0 mm, ndi 3.0 mm.
•Ulusi wopanda kuwala, Chingwe Cholowera/Chotulutsa cha 0.9 mm, 2.0 mm, ndi 3.0 mm.
Mapulogalamu
- HFC (network ya ulusi ndi coaxial ya CATV, CCTV)
- Mapulogalamu onse a FTTH.
- Dongosolo la netiweki ya fiber optic yopanda ntchito.
Mawonekedwe
•Njira zodziwika bwino zopangira FBT
•Kuchita bwino kwa Broadband
•Kukhazikika kwa chilengedwe
•Kugawanika kwa ma polarization sikukhudza
•Phukusi laling'ono kapena lolimba
•Zolumikizira zokhazikika ndi zingwe zolumikizira zikupezeka.
•Yopangidwa ndi ukadaulo wosakanikirana.
•Kutayika Kochepa kwa Kuika (IL)
•Kudzipatula kwakukulu-
•Kutayika Kotsika Kodalira Polarization (PDL)
•Fyuluta ya WDM ya doko la 1x2 yokhala ndi kapangidwe kakang'ono
•Mafunde ogwirira ntchito osiyanasiyana
•Kudalirika kwambiri komanso kukhazikika kwambiri
