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.

Gooch & Housego’s FFW-X wavelength division multiplexers (WDMs) are single mode (SM) optical fiber components and modules. They enable two or three wavelengths to be combined or separated. For the FFW-X series, Gooch &Housego (G&H) utilizes low-loss fused fiber technology – no light leaves the fiber and therefore no alignment is required and there are no unwanted reflections. Furthermore, the output fiber pigtails may be directly integrated into beam delivery systems. These high-performance parts are available in many wavelength configurations (including a duplexing version), fiber and connector options, with standard as well as subminiature packages. They can therefore be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds. Visible Wavelength Combiners:Designed for applications in display systems, sensors and biomedical equipment, G&H’s FFW-xxxxxxxxx single mode visible wavelength fused fiber combiners enable any two or three primary colors in the visible wavelength region to be combined or separated. Visible wavelength combiners are available for either two (red/green, blue/green, red/blue light) or three wavelengths, providing full RGB operation and enabling full color displays. All variants are available on a custom basis, so please contact AMS Technologies to discuss your specific requirements. Near Infrared WDMs:Designed for applications in fiber laser, sensing, biomedical, military and avionics, the FFW-xxxxxxxxx near infrared WDMs enable the low-loss combining or splitting of a pair of wavelengths within the 700 nm to 1199 nm region. G&H can rapidly produce such custom WDMs, with typical minimum wavelength separation of 50 nm. Specific applications could include combining two sensor wavelengths onto one fiber, splitting laser harmonics, or combining wavelengths in fiber lasers. WDMs for 2 µm Operation:Gooch & Housego’s FFW-xxxxxxxxx fused WDMs for 2 µm operation combine multiple wavelengths of light in single mode (SM) fiber whilst maintaining low loss. G&H proprietary manufacturing technology provides low loss with low polarization dependence (PDL). The all-fiber construction offers excellent reliability and high power handling characteristics. These high-performance parts are available in many wavelength configurations, housing, fiber and connector options and can therefore be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds. Duplexing WDMs 1310/1550 nm & 1625 nm (FFW-4xxxx11xx):G&H’s FFW-4xxxx11xx series of duplexing WDMs enable the low-loss combining or splitting of a pair of wavelengths. 1310 nm/C band or 1310 nm/L band components are used to double network bandwidth whilst the 1310/1625 nm component is used to add or drop a supervisory wavelength from a system. G&H proprietary manufacturing technology provides uniquely low excess loss and wavelength dependence along with low polarization and temperature dependence for all ports. In addition to the standard wavelengths, other combinations such as 1550/1625 nm are available. Please contact AMS Technologies with your specific requirements.
