HI REL PM LOW RATIO TAP COUPLER
Fused Fiber PM Tap for use in Undersea and Space applications.
High Reliability (HI REL) Components are deployed in environments such as undersea and space, where the costs of component replacement are prohibitive.
Gooch & Housego 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 manufacturing history of very reliable terrestrial components. Full facilities are available to perform customer-specific HI REL qualification programs, which can consist of accelerated ageing and Weibull analysis.
Manufacturing is carried out on specially-developed workstations. Advanced fiber management, inprocess screening and customer-specific validation tests are implemented, to further enhance component reliability.
The G&H fused PM low ratio tap, taps-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.
Components are supplied in regular (bare fiber) or custom housings, depending on the installation environment.

1 All specifications are for operation on fast axis at center wavelength, room temperature, SOL (start of life) and no guard banding.
2 Tap path not specified for PER
3 Center wavelength selected from within the available wavelength range supplied.
4 Return loss is the ratio of power launched to power reflected for port P1. Directivity for the 2x2 component is the ratio of power launched to P1 to the power reflected to P4. Guaranteed by design.
5 Fiber and taper proof tested during build to confirm strength.
