1x3 single mode 1310/1550nm optical fiber coupler, Low insertion
loss 3 way optical splitter 3 in 1 out SC/APC connector
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.
