1×2 1490 & 1550nm Dual Window Singlemode FBT Coupler Splitter With ABS Box

1×2 1490 & 1550nm Dual Window Singlemode FBT Coupler Splitter With ABS Box

The 1×2 1490 & 1550nm Dual Window Singlemode FBT Coupler Splitter With ABS Box is a high-precision optical power-splitting device engineered for reliable performance across the 1490 nm (E-band) and 1550 nm (C-band) wavelength windows. Manufactured using advanced Fused Biconical Taper (FBT) technology, this splitter delivers low insertion loss, accurate split ratios, excellent wavelength stability, and consistent optical characteristics for dual-wavelength fiber-optic communication systems.

Encased in a durable ABS protective box, the splitter provides enhanced mechanical stability and convenient installation into fiber distribution frames, patch panels, and customer premises equipment. The high-quality fused-taper design ensures low polarization-dependent loss (PDL) and stable performance under various network conditions.

Available in multiple split/coupling ratios—such as 50/50, 60/40, 70/30, 80/20, and 90/10—this dual-window coupler splitter is ideal for FTTH/FTTx deployments, EPON/GPON PON systems, CATV distribution networks, CWDM/DWDM monitoring, optical sensing, and fiber-optic test environments requiring precise and stable signal branching.
