Fiber Optic Coupler

Fiber optic couplers are devices used in fiber optic networks to split or combine optical signals. They are part of the supply class Fiber Optic Interconnectors, which includes various components used to connect and terminate fiber optic cables.

Fiber optic couplers, also known as splitters, are used to divide an incoming optical signal into multiple output signals or combine multiple input signals into a single output signal. They are commonly used in telecommunications, data centers, and other applications where multiple signals need to be distributed or combined.

Fiber optic couplers can be categorized into different types based on their operating principle. Some common types include:

1. Fused Biconical Taper (FBT) Couplers: These couplers are made by fusing and tapering two or more fibers together. They are cost-effective and widely used for splitting or combining signals.

2. Planar Lightwave Circuit (PLC) Couplers: PLC couplers are fabricated using lithographic techniques on a silica substrate. They offer low insertion loss, high reliability, and excellent uniformity.

3. Wavelength Division Multiplexing (WDM) Couplers: WDM couplers are used to combine or separate signals of different wavelengths in wavelength division multiplexing systems. They enable multiple signals to be transmitted over a single fiber.

Fiber optic couplers are essential components in fiber optic networks, allowing for efficient signal distribution and management. They are available in various configurations, including single-mode and multimode options, with different splitting ratios and connector types.

In summary, fiber optic couplers are devices used to split or combine optical signals in fiber optic networks. They are part of the Fiber Optic Interconnectors supply class, which includes various components used in fiber optic systems.
