Gooch & Housego’s range of high reliability (HI-REL) fused fiber optic components are deployed in environments such as undersea and space where the costs of component replacement are prohibitive, and reliability is of premier concern. Gooch & Housego (G&H) is established as a supplier of these components to major undersea equipment manufacturers. G&H’s HI-REL capability is built upon the foundation of a long-established history of manufacturing very reliable components for land-based (or terrestrial) systems in volume.

Full facilities are available to carry out customer-specific HI-REL qualification programs, which can include accelerated ageing and Weibull analysis. Manufacturing is carried out on specially developed workstations. Advanced fiber management, in-process screening and customer-specific validation tests are implemented to further enhance component reliability.

Failure rates for undersea telecommunication systems and components are often described using a FIT rate (Failures in Time). The fused fiber couplers from our HI REL coupler range offer a very low 0.1 FIT rate, equivalent to one failure in roughly fifty thousand components in 25 years.

The ultra-low loss of G&H fused fiber components helps to promote low noise figure and improved system margin in undersea transmission systems. Components are supplied in regular (bare fiber), semi-ruggedized (ø0.9 mm sleeving) or custom housings, depending on the installation environment. Please contact AMS Technologies to discuss your specific requirements.

Services for HI REL customers include custom qualification programs, dedicated workstations, full traceability of materials and processing, advanced fiber management, and customer-specific validation tests. G&H high reliability fused fiber optic component types available include fused fiber couplers, tap couplers, wavelength division multiplexers (WDMs) and pump combiners:

FFC-xxxxHBxx0 series high reliability fused couplers are available for the 980 nm band (FFC-xx3xHB2x0) with coupling ratios of 5%, 10% or 50% and OFS–BFO5635–02 optical fiber as well as for C or L band (FFC-xxxxHB1x0) with coupling ratios of 2%, 5%, 10% or 50% and Corning SMF-28e+ Photonic optical fiber.

FFP-xx3xxxHx0 series high reliability fused polarization maintaining (PM) couplers are available for five wavelength ranges from 915 to 1599 nm with coupling ratios of 1%, 5%, 10% or 50% and 250 µm buffer Panda PM optical fiber.

FPU-XXX3XXHX0 series high reliability PM low ratio tap couplers tap-off low power from a signal path whilst maintaining polarization through the component. G&H proprietary PM manufacturing technology provides tap ratios as low as 0.01% with ultra-low loss and high polarization extinction ratio. These PM low ratio tap couplers are available for any operating wavelength from 1450 to 1620 nm with coupling ratios of 0.01%, 0.1%, 1%, 5% or 10% and Nufern PM14XX C-A optical fiber.

FFW-xC3xH2xx0 series high reliability wavelength division multiplexers (WDMs) are available for 1550 nm (C band) signal wavelength and pump wavelengths of 980 nm (FFW-5C3xH22x0, OFS BFO5635-02 optical fiber) as well as 1480 nm (FFW-3C3xH21x0, Corning SMF-28e+ Photonic optical fiber).

FPW-5C3xH2xx0 series high reliability 980/1550 nm PM wavelength division multiplexers (WDMs) combine multiple wavelengths of light in PM fiber whilst maintaining polarization. In common with all PM components, it is necessary to launch into either the slow or the fast axis to maintain polarization. For the G&H FPW-5C3xH2xx0 PM WDMs, specifications are based on slow axis launch, although fast axis versions are also available if requested.

PBC-xxxxxxxxx series high reliability polarization beam combiners enable the efficient combination of two orthogonally polarized sources of light into a common output fiber. This allows EDFA (Erbium Doped Fiber Amplifier) designers to double pump powers whilst ensuring pump redundancy should a pump failure occur, enabling higher power EDFAs and in turn greater data carrying capacity. Applications include high-power optical amplifiers and undersea systems. All ports consist of polarization maintaining fiber.

18-X Dual-clad Fiber Couplers

Fused; Fiber Type DC (Nufern SM-9/105/125), MM (Nufern 105/125, 250), SM (SMF-28); 1250-1700 nm; Number of Legs 1x2, 2x2; SM IL ≤0.5-≤3.7 dB; Dimensions Ø2.9x50.8 mm Gooch & Housego’s (G&H) 18-X series of fused dual-clad fiber (FDCF) couplers and optical splitters offers a high coupling efficiency for multi mode (MM) fiber over a broad wavelength range with a low wavelength dependent loss. Light launched in the single mode core of the input single mode (SM) fiber or dual-clad (DC) fiber will transmit 100% through G&H’s 18-XXXXX-XX-XXXXX series FDCF coupler directly to the inner core of the output DC fiber, while light launched in the inner cladding of the DC fiber will couple to the multi mode (MM) fiber with at least 50% coupling efficiency depending on the core size of the MM fiber as a bigger MM fiber (i.e. 250 µm core) results in a higher coupling transmission percentage (70% or higher) to the MM fiber. As different DC fibers have different operating wavelength ranges, proper choice of SM fiber is very important for building a high-performance FDCF coupler. The typical 2x2 FDCF couplers have DC fiber in two opposite leads and MM fiber in the other two arms. The DC input fiber can be optionally replaced with a matching SM fiber and the MM output fiber can be terminated to form a 2x1 FDCF coupler.

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.

FFS-X SM Fiber Couplers

Fused; Fiber Type SM; 450-1599 nm; Number of Legs 1x2, 2x2; Splitting Ratio 1/99,999-50/50, Other; Fiber Length 0.5, 1 m; RL ≥50 dB; Dimensions Ø3.0x50/60, Ø5.0x75, 80x10x8, 5x5x85 mm Gooch & Housego’s FFS-X series of single mode (SM) fiber couplers split or combine light in the visible or (near) infrared regions. The couplers utilize Gooch & Housego’s (G&H) low-loss fused fiber technology. No light leaves the fiber, therefore no alignment is required and there are no unwanted reflections. Furthermore, the output fiber pigtails may be directly integrated into beam delivery systems. Visible Wavelength SM Fiber Couplers:Within the FFS-xxxxxxxxx series of visible wavelength fiber couplers, versions optimized for any wavelength within the range of 450 to 700 nm may be selected. These couplers are designed for applications in display systems, sensors and biomedical equipment. Near Infrared SM Fiber Couplers:G&H’s FFS-xxxxxxxxx series of near infrared couplers splits light at any selected wavelength from 700 to 1199 nm. These couplers are designed for applications in fiber laser, sensor and avionics applications. Ultra-low Ratio Tap SM Fiber Couplers:G&H’s FFS-xxxxxxAxx series of ultra-low ratio tap couplers splits a very small amount of light from a signal path to a tap port. Suitable for very high optical power, its main application is in the monitoring of optical sources such as fiber lasers. Low tap ratios such as 0.1%, 0.01% or 0.001% enable the monitoring photodetector to operate without damage or saturation. Gooch & Housego proprietary manufacturing technology provides ultra-low loss in the signal path, thereby maximizing optical power handling. Consistently high return loss (>55 dB) reduces the amount of optical power reflected back along the input fiber. This helps the fiber laser operate in a stable manner. Standard ultra-low ratio parts are available for wavelengths from 700 to 1599 nm. For other wavelengths, coupling ratios or customized fiber types please contact AMS Technologies.
