This 1310nm/1550nm fiber optic coupler (optical splitter) is Telcordia GR-1221/GR-1209 and RoHS compliant. It works well even in the outdoor application or harsh environment.
1310nm/1550nm Fiber Optic Coupler (Optical Splitter): Single mode Fiber Coupler
Usually, optical fiber coupler has only one input or one output. A coupler with only one input is also known as an optical splitter or beam splitter, and the one with only one output is referred to as a combiner. The beam splitter/combiner forms the most common type of fused biconical taper (FBT) coupler-based branching components. They are widely used in fiber optic networks, being deployed as a standalone component for fiber-to-the-home applications or many other places that fiber signal splitting are required. A beam splitter/combiner is a symmetric fiber coupler with identical constituent fibers.

Sometimes, 1 by 2 and 2 by 2 fiber optic couplers are highly asymmetric (with splitting ratios from less than 1% to 50%, also called tap couplers). This kind of fiber optic coupler branch off a small portion of the signal power, for example, for monitoring signal level status in a fiber transmission link.
With the excellent FBT (fused biconic taper) method, Lfiber design and provide high-end optical couplers for customers all over the world. Since Lfiber has invested a great deal of time and effort in R&D, we are now able to offer a variety of optical fiber couplers and fused WDMs (wavelength combiner/splitter) with different operating wavelengths, fiber types, connector types, handling power, package sizes, etc. Also, we support customizing these fiber optic components for specific applications on request.
