HIGH RELIABILITY 980/1550 nm PM WDM
Fused Fiber PMWDM 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, in-process screening and customer-specific validation tests are implemented, to further enhance component reliability.
The G&H fused PM WDM, combines 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 PM WDM, specifications are based on slow axis launch, although fast axis versions are also available if requested.
Components are supplied in regular (bare fiber) or custom housings, depending on the installation environment.

1 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.
2 For operation at powers of greater than 4 W the component housing and fiber must be adequately heat-sunk (for additional information contact G&H sales). Components intended for high power operation are only available in the 2x2 configuration.
Component performance and reliability under high power must be determined within the customer system.
3 Fiber and taper proof tested during build to confirm strength.
