ITU-G.657B3 Chingwe chosavuta kupinda
Tsegulani WhatsApp App
Mtundu:
Bend Insensitive Single-mode Optical Fiber (G.657.B3)
Zokhazikika:
CHIKWANGWANI chimatsatira kapena kupitilira luso la ITU-T G.657.A1/A2/B2/B3.
Mbali:
Malo ocheperako opindika 7.5mm, katundu wapamwamba wotsutsana ndi kupinda;
Zogwirizana kwathunthu ndi G.652 single-mode fiber. Kutumiza kwa gulu lonse (1260 ~ 1626nm);
Kutsika kwa PMD kwa kuthamanga kwapamwamba komanso kufala kwamtunda wautali. Kutsika kwapang'onopang'ono kwapang'onopang'ono, komwe kumagwiritsidwa ntchito pamitundu yonse yama chingwe kuphatikiza nthiti;
Parameter yapamwamba yoletsa kutopa imatsimikizira moyo wautumiki pansi pa ma radius ang'onoang'ono opindika.
Ntchito:
zomangamanga zonse chingwe, 1260 ~ 1626nm zonse gulu kufala, FTTH liwilo kuwala wodutsa, kuwala chingwe mu utali wozungulira yaing'ono, ang'onoang'ono kuwala CHIKWANGWANI chingwe ndi chipangizo.

Mu 2004, GL CHIKWANGWANI anakhazikitsa fakitale kubala mankhwala chingwe kuwala, makamaka kubala dontho chingwe, panja kuwala chingwe, etc.
GL CHIKWANGWANI tsopano waika 18 wa zida mitundu, 10 wa seti ya yachiwiri pulasitiki ❖ kuyanika equipments, 15 akanema SZ wosanjikiza zida zokhotakhota, 16 waika zida sheathing, 8 waika zida FTTH dontho chingwe kupanga, 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.
