G.652D Single-mode Optical fiber (B1.3)
Madzi otsika pachimake osabalalitsa kusamutsidwa single-mode CHIKWANGWANI ndi oyenera kufala dongosolo lonse gulu 1280nm ~ 1625nm, amene osati amasunga otsika kubalalitsidwa chikhalidwe gulu 1310nm, komanso ali ndi imfa otsika pa 1383nm, kupanga E band. (1360nm ~ 1460nm) yogwiritsidwa ntchito mokwanira. Kutayika ndi kubalalitsidwa kwa gulu lonselo kuchokera ku 1260nm kupita ku 1625nm kumakongoletsedwa, ndipo kutayika kopindika kwa 1625nm wavelength kumachepetsedwa, komwe kumapereka zothandizira bandwidth kwa network ya msana, MAN ndi netiweki yofikira.

G.657A1 Ulusi wopindika wa single-mode
Mankhwalawa amatengera luso lazopangapanga lopangira ndodo, lomwe limatha kuwongolera OH-omwe ali ndi ndodo yopangidwa ndi fiber mpaka pamlingo wotsika kwambiri, kotero kuti mankhwalawa ali ndi mphamvu yabwino kwambiri yochepetsera komanso nsonga yamadzi otsika, ntchito yabwino kwambiri yotumizira. Mankhwalawa amatha kuonetsetsa kuti pali utali wopindika pang'ono pomwe akugwirizana kwathunthu ndi netiweki ya G.652D, kotero CHIKWANGWANI chimatha kukwaniritsa zofunikira zama waya za FTTH.

Madzi otsekereza chingwe chodzaza Jelly
Cable jelly ndi chisakanizo chokhazikika chokhazikika cha hydrocarbon yolimba, yolimba komanso yamadzimadzi. Jelly ya chingwe imakhala yopanda zonyansa, imakhala ndi fungo losalowerera ndale ndipo ilibe chinyezi.
M'kati mwa zingwe zoyankhulirana za pulasitiki, anthu amazindikira kuti chifukwa cha pulasitiki imakhala ndi chinyezi china, zomwe zimapangitsa kuti chingwecho chikhale ndi mavuto m'mawu amadzi, nthawi zambiri chimayambitsa chingwe chachikulu ndi kulowerera kwa madzi, kukhudzidwa kwa kulankhulana, kusokonezeka kwa magetsi. kupanga ndi moyo.
