1×2 single-mode FBT coupler is designed for efficient optical power splitting in fiber networks. Utilizing fused biconical taper (FBT) technology, it ensures low insertion loss and excellent uniformity across both 1310nm and 1550nm wavelengths (dual window). The bare fiber (250μm) construction allows for easy splicing and integration into various optical systems, making it ideal for FTTx, passive optical networks (PON), and laboratory applications.
