Single Mode Three Window 1x2 Fiber Optic Coupler Splitter 50/50 Split Ratio
Three-Window Coupler (TWC) is Built by asymmetric coupling technique, TWC operating bandwidth is expanding to 1310nm, 1490nm and 1550nm three communication windows. The TWC coupler has the same coupling ratio on 1310, 1490 and 1550nm communication windows, with low excess loss and low PDL. TWC is widely used for communication systems, CATV, FTTH, where multiple optical signals pass through single fiber.
Feature:
High Stability and Reliability
Low Insertion Loss
Low Polarization Dependent Loss
Wide Operation Wavelength
Application:
FTTX networks
CATV links
PON networks
