FTTH High performance FBT fiber optic splitter coupler

Kufotokozera Kwachidule:

FBT ndi mtundu waufupi wa Fused Biconic Taper ziboda, izo zochokera luso chikhalidwe, kuti mtolo pamodzi awiri kapena kuposa kuwala ulusi, ndiyeno kukoka chulucho makina Sungunulani anatambasula, ndi zenizeni nthawi kuwunika kusintha kwa chiŵerengero, sipekitiramu chiŵerengero zofunika mutatha kusungunula, mbali imodzi imasunga ulusi umodzi (yonse yodulidwa) monga chothandizira, mapeto ena ndi kutulutsa njira zambiri.

Monga chimodzi mwa zigawo zikuluzikulu za maukonde a GPON FTTx, optical splitters akhoza kuikidwa mu Central Office kapena mu imodzi mwa malo ogawa (kunja kapena m'nyumba) chifukwa ma FBT copers ndi okhazikika kwambiri kwa ma multiport optical signal kugawanika ndi kutayika kochepa. FBT ma couplers adapangidwa kuti azigawanitsa mphamvu ndikugogoda pazida zoyankhulirana, netiweki ya CATV, ndi zida zoyesera.

Zogulitsa Zamankhwala

1. Kufanana kwabwino komanso kutayika kochepa kolowetsa
2. Low Polarization Dependent Loss
3. Wabwino Zimango
4. Malo ogwirira ntchito: -40ºC mpaka +85ºC
5. High Polarization Extinction Ratio & Excellent Uniformity
6. Kulowetsa kwa CHIKWANGWANI: 0.9mm kapena 250μm CHIKWANGWANI chosankha
7. Kutulutsa kwa CHIKWANGWANI: 250μm wopanda CHIKWANGWANI (Ndiwopindulitsa pakuphatikiza) G.657A CHIKWANGWANI

Zofunsira Zamalonda

1. Fiber to the point (FTTX)

2. CHIKWANGWANI chakunyumba (FTTH)

3. Passive Optical network (PON, GEPON)

4. Manetiweki amdera lanu (LAN)

5. Cable TV (CATV)

6. Zida zoyesera
