FTTH Waxqabadka sare ee FBT fiber optic splitter lamaanaha

Sharaxaad Gaaban:

FBT waa qaabka gaaban ee Fused Biconic Taper splitter, waxay ku salaysan tahay tignoolajiyada soo jireenka ah, in la isku xidho laba ama in ka badan oo fiilooyinka indhaha ah, ka dibna la jiido kala jiidashada mashiinka koodhka, iyo kormeerka waqtiga dhabta ah isbeddelka saamiga, shuruudaha saamiga muuqaalka. Kala-baxa dhalaalka ka dib, hal dhinac ayaa haysta hal fiber (inta soo hadhay ee la gooyey) sida gelinta, dhamaadka kale waa wax soo saar badan oo kanaal ah.

Sharaxaada Alaabta

Sida mid ka mid ah qaybaha muhiimka ah ee shabakadaha GPON FTTx, kala qaybiyeyaasha indhaha waxaa lagu dhejin karaa Xafiiska Dhexe ama mid ka mid ah meelaha wax lagu qaybiyo (dibadda ama gudaha) sababtoo ah FBT coupers aad ayey u xasilan yihiin kala qaybsanaanta calaamadaha indhaha ee multiport oo leh khasaaro galinta hoose. Lammaanayaasha FBT waxaa loogu talagalay kala qaybinta korontada iyo ku dhejinta qalabka isgaarsiinta, shabakada CATV, iyo qalabka tijaabada.
