Product Details
CATV 5 way fused FBT passive fiber splitter 1x5 singlemode optical
coupler module with 20% splitting ratio
Dual window coupler (DWC) is built by asymmetric coupling
technique. The operating bandwidth of this normal coupler is
expanding to ±40nm, and the ultra broadband coupler is expanding to
±80nm. The DWC coupler has the same coupling ratio on both 1310nm
and 1550nm communication windows, and with low excess loss and low
PDL. DWC couplers are widely used for communication systems, CATV,
and FTTH.
