1×2 1310 & 1550nm Dual Window Singlemode FBT Coupler Splitter With ABS Box

1×2 1310 & 1550nm Dual Window Singlemode FBT Coupler Splitter With ABS Box

The 1×2 1310 & 1550nm Dual Window Singlemode FBT Coupler Splitter With ABS Box is a high-performance optical power-splitting device engineered for stable and precise operation across both the 1310 nm (O-band) and 1550 nm (C-band) wavelength windows. Utilizing advanced Fused Biconical Taper (FBT) technology, this splitter ensures low insertion loss, accurate split ratios, excellent wavelength stability, and reliable performance for multi-wavelength optical communication systems.

Encased in a durable and compact ABS box, the device provides enhanced mechanical protection and ease of installation, making it ideal for integration into fiber distribution frames, patch panels, and customer premises equipment. Its high-quality fused taper structure ensures low polarization-dependent loss (PDL) and consistent optical characteristics, even under varying environmental conditions.

Available in multiple split/coupling ratios—such as 50/50, 60/40, 70/30, 80/20, and 90/10—this dual-window FBT coupler splitter is widely used in FTTH/FTTx networks, EPON/GPON PON systems, CATV distribution, CWDM/DWDM monitoring, optical sensing, and fiber-optic test setups requiring accurate and stable signal branching across both wavelength bands.
