OZ Optics’ FOBS-12N series of miniature polarization maintaining fiber optic beam splitters are used to split the light traveling through a fiber into two fibers, or to split or combine orthogonally polarized light into separate fibers. These splitters feature a rugged miniature housing to fit into compact spaces in equipment and systems.

Light from a fiber is first collimated, then sent through a beam-splitting optic to divide it into two beams by either a fixed ratio or into two orthogonal polarizations. The resultant output beams are then coupled back into the output fibers. This flexible design allows splitters with different fiber types on the input and output ports. For example, light from a single mode fiber could be split into its two orthogonal states and then launched into two polarization maintaining fibers. Standard products for 1550 nm applications are readily available, while custom items can be made with rapid turnaround at low cost. Products for other wavelengths, such as 980 nm, 1300 nm, or 1480 nm are offered. Contact AMS Technologies for details and a quotation.

Also known as optical taps, the FOBS-12N series of miniature polarization maintaining splitters use a partially reflecting mirror to transmit a portion of the light from the input fiber to the main output fiber and reflect the remainder of the light to the second output fiber. All ports using polarization maintaining fiber are aligned so that polarized light aligned parallel to the stress rods on the input fiber emerge from the output fibers in the same manner, maintaining the polarization state to a high degree. Splitters that only split off a small portion of the input light are commonly known as taps. These splitters are often used for power monitoring applications. The small signal, typically between 1% and 10%, is sent to a monitoring photodiode, while most of the signal goes on to the main destination.
