Qaabka qeexida:foorarsi aan dareen lahayn oo hal qaab ah (G.657A2)
Heerka fulinta:Buuxi shuruudaha ITU-T G.657.A1/A2/B2 tifaftirka farsamada fiber indhaha.
Tilmaamaha alaabta:
- Radius foorarsiga ugu yar wuxuu gaari karaa 7.5mm, oo leh iska caabin foorarsi heer sare ah;
- Si buuxda ula jaan qaada G.652 fiber hal-hab ah;
- 1260 ~ 1626nm gudbinta hirarka buuxa;
- Kala firdhinta qaabka hoose ee polarization waxay buuxisaa baahiyaha gudbinta xawaaraha sare iyo fogaanta;
- Loo isticmaalo fiilooyinka indhaha ee kala duwan, oo ay ku jiraan fiilooyinka indhaha ee ribbon, oo leh hoos u dhac dheeraad ah oo aad u yar ee leexinta yar;
- Waxay leedahay heerar sare oo ka-hortagga daalka si loo hubiyo in nolosha adeegga hoosteeda foorarsiga yar yar.
- Fiiro gaar ah Codsiga: Waxaa lagu dabaqaa fiilooyinka indhaha ee qaabab kala duwan, gudbinta hirarka buuxa ee 1260 ~ 1626nm, FTTH-xawaaraha sare ee xawaaraha sare ee indhaha, fiilooyinka indhaha ee leh shuruudaha radius qalloocan yar, fiilooyinka indhaha ee yar yar iyo aaladaha fiber indhaha, iyo shuruudaha isticmaalka L-band.
