2x2 Fiber Coupler

In today's world, from the internet in your home to big lab setups, splitting a light signal reliably is a must. That's where our 2x2 fiber coupler comes in. I think it's a fantastic, no-fuss component for the job. Housed in a tough ABS box and fitted with standard FC/APC connectors, this unit gives you great performance and flexibility. It simply takes an input signal and splits it cleanly into two outputs, keeping your network running smoothly.

This is a key piece for any passive optical network (PON). We make it using the trusted Fused Biconical Taper (FBT) process. Basically, we carefully fuse and taper the fibers to create a spot where light can share between them. This allows for very precise power splitting. It's not just a simple splitter; it gives you a defined ratio, which is so important for managing signal strength in complex systems.

The 2x2 design means it can handle two inputs and two outputs, which I like for its versatility. It works perfectly with the standard 1310nm and 1550nm wavelengths. This makes it ideal for modern PON systems where different signals travel upstream and downstream. The FC/APC connectors are a great choice because they cut down on light reflection, a real plus for keeping signals clean in systems like CATV.

We build this 2x2 fiber coupler to perform well and last. Here's what you can expect:

• Low Loss:​ It keeps your signal strong, which helps your network reach further.

• High Return Loss:​ The APC connectors minimize reflections. This protects your laser sources from feedback.

• Low PDL:​ The performance stays steady no matter the light's polarization.

• Good Uniformity:​ The split is accurate and consistent on both outputs.

• Tough & Stable:​ We test it to handle changes in temperature, humidity, and stress. I'm confident it will hold up in real-world conditions, indoors or out.
