1×2 1260~1620nm All Band Singlemode FBT Coupler Splitter With Steel Tube

1×2 1260~1620nm All Band Singlemode FBT Coupler Splitter With Steel Tube

The 1×2 1260~1620nm All Band Singlemode FBT Coupler Splitter With Steel Tube is a high-performance optical power-splitting device designed to support the full telecom wavelength range—from 1260 nm to 1620 nm, covering O, E, S, C, L, and U bands. Manufactured using advanced Fused Biconical Taper (FBT) technology, this splitter provides low insertion loss, high splitting accuracy, excellent wavelength stability, and reliable performance across the entire operating band.

Encased in a durable stainless-steel protective tube, the splitter delivers outstanding mechanical protection and long-term environmental resistance, ensuring stable optical characteristics even in harsh field installations. Its precision fused-taper structure enables low polarization-dependent loss (PDL) and highly uniform splitting performance over broad wavelength ranges.

Available in multiple coupling/split ratios—including 50/50, 60/40, 70/30, 80/20, and 90/10—the FBT device is ideal for multi-wavelength optical systems such as FTTH/FTTx deployment, CWDM/DWDM monitoring, PON networks, CATV transmission, optical sensors, and broadband testing.
