1550nm Single Window 1× 2 Single-Mode 2:98 Ratio Fiber Fused
Couplers
Optic Coupler Brief Introduces:
Fiber optical couplers are capable of separating an optical signal
on a single optical fiber into two in a designated ratio, and can
perform the opposite task of combining two signals into one.
Our WDM couplers are capable of dividing two wavelengths on a
single optical fiber into two wavelengths on two fibers, and can
likewise combine two wavelengths on two fibers onto a single fiber.
2× 2 Fiber Optic Coupler Features& Benefits:
1) Low loss&Low WDL
2) Ultra low PDL
3) Ultra wide operation bandwidth +/-80nm
4) High directivity
5) Mini-size package
6) Dual operating window
7) Compact package
