Description
FOBER FBT Coupler (70/30 Steel Tube Type) – Pack of 2
High-Performance Optical Signal Splitter for Reliable Fiber Networks
The FOBER FBT Coupler 70/30 Steel Tube Type is a premium-quality passive fiber optic component used for efficient light signal splitting in single-mode fiber applications. Designed using Fused Biconical Taper (FBT) technology, this coupler ensures precise optical signal distribution, offering a 70% to 30% split ratio. It’s ideal for situations where one output requires the majority of the optical power while a secondary path receives a smaller portion—for monitoring, backup links, or signal analysis.
Enclosed in a durable steel tube, the FOBER 70/30 FBT coupler guarantees rugged protection, long-term performance, and stable optical characteristics. Supplied in a pack of two, this product delivers great value for system installers, network engineers, and fiber optic professionals involved in FTTH, CATV, or PON deployments.
