Loss Over 1×2 Simplex Fiber Optic WDM Coupler 50/50 SC UPC 1310nm
Optic Coupler Brief Introduces:
Fused WDM modules are designed for multiplexing and demultiplexing
two wavelengths. These versatile, mux, and demux products are based
on Fused Taper Fiber technology. This proven technology produces
high-quality 3-port devices with low PDL, low insertion loss, and
stable environment performance.
Single-mode wideband couplers have 80nm bandwidth, compared to 40nm
of standard single-mode couplers. This product has very low excess
loss and high-temperature stability.
Coupling ratio can be specified. Couplers working at center
wavelength other than 1550nm or 1310nm can also be provided.
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
