G.652 Standard ib hom fiber ntau yog dab tsi?
G. 652 fiber ntau yog thawj tiamtib - hom fiber ntau, tus cwj pwm los ntawm qhov tsis muaj fiber ntau dispersion thaum lub sijhawm ua haujlwm wavelength ntawm 1300NM, thiab qhov kev sib kis ntawm qhov system tsuas yog txwv los ntawm fiber ntau attenuation. Tab sis hom fiber ntau no muaj qhov poob qis hauv 1300NM band, xws li 0.3 txog 0.4dB / km; Qhov poob hauv 1550NM band yog me me, xws li 0.2 ~ 0.25dB / KM. Lub dispersion nyob rau hauv 1300nm band yog 3.5ps / (nm / km), thiab nws loj dua nyob rau hauv 1550nm band, txog 20ps / (nm / km). Hom fiber ntau no tuaj yeem siv tau rau 2.5Gbit / s lub cev lub cev hauv 1550nm band, tab sis vim muaj qhov sib txawv loj hauv pawg no, yog tias lub teeb liab 10Gbit / s raug xa mus rau qhov deb ntawm ntau tshaj 50KM, yuav tsum muaj qhov cuam tshuam loj ntawm cov nyiaj them poob haujlwm. Tsis tas li ntawd, nws txoj kev siv kuj ua rau cov kab poob thiab txo qis relay nrug, yog li nws tsis haum rau DWDM systems.

FAQ
Q: Qhov txawv ntawm APC thiab UPC polish hom yog dab tsi?
A: APC (Angled Physical Contact)connectors muaj lub ntsej muag kawg uas txo cov kev xav rov qab. UPC (Ultra Physical Contact) connectors muaj lub ntsej muag tiaj tus kawg. APC yog qhov zoo dua rau kev xav txog - cov ntawv thov nkag siab.
Q: Cov ntaub ntawv tsho dab tsi muaj?
A: Peb lub tsho xaiv muaj: PVC, LSZH (Tsawg Haus Luam Yeeb Zero Halogen), thiab OFNP (Optical Fiber Nonconductive Plenum).
Q: Dab tsi cable diameters kuv tuaj yeem xaiv?
A: Cov khoom no muaj nyob rau hauv 3.0mm, 2.0mm, thiab 0.9mm txheej diameters.
Q: Kuv puas tuaj yeem xaj cov khoom sib txawv ntawm txhua qhov kawg?
A: Yog. Cov kev xaiv Connector suav nrogLC, SC, ST, FC, thiab MU. Tiv tauj peb rau hybrid configurations.
Q: Puas muaj kev cai ntev?
A: Yog. Kev cai ntev tuaj yeem tsim tau raws li qhov project xav tau.
