FOBER FBT COUPLER (55/45 STEEL TUBE TYPE) (2 NOS)

FOBER FBT Coupler (55/45 Steel Tube Type) – 2 Nos

The FOBER FBT Coupler (55/45 Steel Tube Type) is a high-quality optical device designed for efficient power splitting and combining in fiber optic communication systems. This pair of couplers is engineered with precision using Fused Biconical Taper (FBT) technology, delivering reliable performance in FTTH (Fiber to the Home), CATV, optical networks, and data transmission systems.

Each coupler in the pack features a 55/45 split ratio, making it ideal for applications where slightly asymmetric power distribution is required. Housed in durable steel tube casing, these couplers offer enhanced protection and long service life, even in challenging environmental conditions.

Reliable Performance with 55/45 Power Splitting Ratio

The FBT 55/45 split ratio allows for the controlled distribution of optical signals where one output receives 55% of the input power and the other 45%. This makes it suitable for use cases such as network monitoring, optical signal routing, redundant link configurations, and signal tapping without significantly degrading signal quality.

This balance provides greater flexibility over equal (50/50) splitters, especially in networks where slightly more power is needed on one line than the other.

High-Quality FBT Technology

FBT (Fused Biconical Taper) couplers are known for their cost-effectiveness, stability, and performance in single-mode fiber systems. The FOBER FBT Coupler uses advanced tapering and fusion technology to ensure precise core alignment and minimal excess loss. It supports single-mode fiber (SMF-28) and is optimized for operation in the 1310 nm and 1550 nm wavelength ranges, ensuring compatibility with most optical network equipment.

Steel Tube Encapsulation for Maximum Protection

Both couplers come housed in a compact stainless steel tube, which provides excellent protection against moisture, mechanical stress, and environmental exposure. This rugged casing ensures the couplers can be safely installed in outdoor junction boxes, distribution panels, or within harsh industrial environments, making them ideal for both indoor and outdoor use.

Low Insertion Loss and High Return Loss

The FBT couplers are manufactured to maintain low insertion loss, typically around <3.6 dB for the main path and <4.0 dB for the secondary path. They also feature a high return loss (≥ 55 dB), which is essential to minimize signal reflection and ensure stable system performance.

This makes the FOBER 55/45 FBT coupler highly efficient for long-distance transmissions and dense wavelength division multiplexing (DWDM) systems.

Plug-and-Play Design for Easy Integration

Each coupler comes terminated with standard SC/APC or SC/UPC connectors (customizable upon request), which allows for plug-and-play installation in any fiber optic setup. The steel tube format with fiber pigtails makes it easy to integrate with patch panels, splice trays, or directly into network cabinets.
