ITU-T G652D Zero Water Peak SM Optical fiber, Ulusi wamtundu umodzi wamtundu umodzi umatchedwanso ulusi wamtundu umodzi wosabalalika wokhala ndi bandi yotalikirapo yomwe imagwiritsidwa ntchito kwambiri pakali pano.Kutalika kogwira ntchito kumatha kuchokera ku 1310nm ndi 1550nm.
Kufotokozera:
Ulusi Wamtundu Umodzi Wosinthika Nondispersion wokhala ndi Wavelength-segment Extension (G652D)
Muyezo wotsatira:
Imakwaniritsa ndikudutsa zofunikira za ITU-T G.652.D&IEC B1.3
Zogulitsa:
1260 ~ 1625mm kufala kwa gulu lonse, magwiridwe antchito abwino kwambiri amakwaniritsa zofunikira za DWDM ndi machitidwe a CWDM
Malangizo ogwiritsira ntchito:
Oyenera mitundu yonse ya kapangidwe chingwe kuwala, kuphatikizapo kuwala CHIKWANGWANI chingwe, sheathed anagona chingwe, chigoba chingwe, chapakati chubu chingwe ndi sheathed chingwe, etc.

Mu 2004, GL CHIKWANGWANI anakhazikitsa fakitale kubala mankhwala chingwe kuwala, makamaka kubala dontho chingwe, panja kuwala chingwe, etc.
GL CHIKWANGWANI tsopano 18 waika zida utoto, 10 wa seti ya yachiwiri pulasitiki ❖ kuyanika equipments, 15 waika SZ wosanjikiza zida zokhotakhota, 16 waika zida sheathing, 8 waika FTTH dontho zipangizo kupanga chingwe, 20 ya zida OPGW kuwala chingwe equipments, ndi 1 zida zofananira Ndi zida zina zambiri zothandizira kupanga.Pakali pano, mphamvu pachaka kupanga zingwe kuwala ukufika miliyoni 12 pachimake-km (avareji tsiku kupanga 45,000 Km pachimake ndi mitundu ya zingwe angafikire 1,500 Km).Mafakitole athu amatha kupanga mitundu yosiyanasiyana ya zingwe zamkati ndi zakunja (monga ADSS, GYFTY, GYTS, GYTA, GYFTC8Y, chingwe chaching'ono chowulutsidwa ndi mpweya, ndi zina).mphamvu ya tsiku ndi tsiku ya zingwe wamba imatha kufika 1500KM/tsiku, mphamvu yopanga tsiku lililonse ya chingwe chotsitsa imatha kufikira max.1200km/tsiku, ndi mphamvu tsiku kupanga OPGW akhoza kufika 200KM/tsiku.
