- Ihambisana ngokugcwele ne-G.652 ye-fibre yemodi eyodwa;
- 1260 ~ 1626nm ukuhanjiswa kwe-waveband egcwele;
- Ukuhlakazwa kwemodi ye-polarization ephansi kuhlangabezana nezidingo zokudlulisa ngesivinini esikhulu kanye nebanga elide;
- Isetshenziswa kumakhebula okubona ahlukahlukene, okuhlanganisa izintambo zokubona iribhoni, ezinokuncishiswa okwengeziwe okuphansi kakhulu kokugoba okuncane;
- Inamapharamitha aphezulu wokulwa nokukhathala ukuqinisekisa impilo yesevisi ngaphansi kweradiyasi encane yokugoba.
- Inothi Lokufaka Isicelo: Isetshenziswa kuzintambo ezibonakalayo zezakhiwo ezihlukahlukene, ukudluliswa kwe-wavelength egcwele ku-1260 ~ 1626nm, umzila we-FTTH wesivinini esiphezulu, izintambo ezibonakalayo ezinezidingo ze-radius encane egobayo, izintambo ezincane ezibonakalayo kanye namadivayisi we-fiber optical, kanye nezidingo. ngokusebenzisa i-L-band.
