Product information "Beamsplitters & Combiners"

PM or SM Splitters/Combiners; 1550 nm, Other; Splitting Ratio 50/50-90/10; PDL ±0.25 dB; Directivity >50 dB

OZ Optics’ fiber optic beamsplitters are used to divide light from one fiber into two or more fibers. Light from an input fiber is first collimated, then sent through a beam-splitting optic to divide it into two. The resultant output beams are then focused back into the output fibers. Both 1xN and 2xN splitters can be constructed in this fashion with as many as eight or more outputs, with both low return losses and low insertion losses.

Standard parts available in this series are FOBS-12P (1x2) and FOBS-22P (2x2) pigtail-style splitters, FOBS-12 (1x2) and FOBS-22 (2x2) receptacle-style splitters, as well as LDBS-12P (pigtail-style) and LDBS-1 (receptacle-style) laser diode to fiber splitters, and finally ULBS-12P (pigtail-style) and ULBS-1 (receptacle-style) laser to fiber splitters

This design is extremely flexible, allowing to use different fiber types on different ports, and different beamsplitter optics inside. Custom designs combining circulators, polarizing splitters and non-polarizing splitters in the same package are routinely manufactured. Splitters can be made with either fibers permanently attached to each port (pigtail style) or with receptacles on each port that one can plug your fiber into (receptacle style). OZ Optics can also build source to fiber couplers with built-in beamsplitters for either laser or laser diode sources. Contact AMS Technologies for details.

If size is a concern, we recommend that you consider OZ Optics’ miniature line of splitters.

Within OZ Optics’ series of beamsplitters and combiners, the two most common types of splitters offered are polarizing beamsplitters and polarization maintaining (PM) beamsplitters. Polarizing beamsplitters split incoming light into two orthogonal states. They can also be used to combine the light from two fibers into a single output fiber. When used as a beam combiner, each input signal will transmit along a different output polarization axis.

PM 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 made using polarization maintaining fiber are aligned so that polarized light aligned parallel to the stress rods on the input fiber emerges 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 and often used for power monitoring applications. For a very cost-effective alternative configuration, combining the functions of a tap and monitor photodiode in a single unit, we invite you to review OZ Optics’ OPM series of inline optical taps and monitors.

FOBS-12N SM Splitters

Single Mode Splitters, Miniature Size; 980 to 1550 nm; Splitting Ratio 50/50 to 98/2; Polarization Dependent Loss 0.1 dB; Directivity >50 dB OZ Optics’ FOBS-12N series of miniature polarizing (single mode) 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. The FOBS-N12 series of polarizing beam splitters split incoming light into two orthogonal states. They can also be used to combine the light from two fibers into a single output fiber. When used as a beam combiner, each input signal will transmit along a different output polarization axis. By default, the output fibers on a polarizing splitter are aligned so that the output polarization from each fiber is in line with the stress rods of the fibers. If the input fiber is a polarization maintaining (PM) fiber, the input fiber is aligned such that light polarized parallel to the fiber’s stress rods is transmitted to port 1 of the splitter, while light polarized perpendicular to the stress rods is transmitted to port 2 of the splitter.
