1x2 4x8 Single Mode FBT Splitter 1310nm 1550nm Fiber Optic Coupler

1x2 FBT (Fused Biconical Taper Splitter):   This splitter couples two or more optical fibers together using fused biconical tapering technology to split optical signals. A 1x2 designation indicates one input port and two output ports, distributing the input optical signal to the two output ports in a specific ratio.

Features

* Splitting Ratio:

   This product has a splitting ratio of 5:95. Common splitting ratios include 50:50 (equal split), 80:20, and 90:10. The specific ratio depends on the model. Equal split types offer the same output power, while non-equal split types are suitable for applications requiring different power levels.

* Operating Wavelength:

   Typically supports 1310nm, 1490nm, and 1550nm, covering telecommunications, datacom, and broadcasting applications (such as PON networks).

* Insertion Loss:

   At a 50:50 splitting ratio, the theoretical loss is approximately 3.5dB (per channel). Actual loss should be referenced in the datasheet, but is generally ≤3.8dB (including additional loss).

* Polarization-Dependent Loss (PDL):≤0.2dB, indicating insensitivity to the optical signal's polarization state.

* Directivity: ≥55dB, ensuring minimal reflected light at the input, reducing interference.

* Packaging Type: Commonly available are bare fiber (requires a junction box) or modular (packaged in an ABS housing or metal tube).

Applications

* FTTH: Distributes downstream signals or combines upstream signals in a PON (Passive Optical Network).

* Fiber Optic Testing: Splits optical light signals to multiple test equipment.

* CATV Networks: Distributes video optical signals to multiple users.

* Sensor Systems: For example, signal splitting in distributed fiber optic sensing.
