PM WDM
Fused Fiber WDM
The Gooch & Housego fused PM WDM, combines multiple wavelengths of light in PM fiber whilst maintaining polarization.
G&H proprietary PM manufacturing technology provides low loss, with high polarization extinction ratio. 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.
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.
Key Features
• Low loss
• High PER
• High power handling
• PM PANDA fiber on all ports
• Slow axis operation as standard
• Fast axis operation available on request
Applications
• Pump signal WDM for EDFA
• Fiber lasers
• Instrumentation

1 Measured reference port P3 input for signal wavelength, P2 input for pump wavelength and P1 input for signal and pump wavelengths.
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 The performance and reliability of optical connectors is not guaranteed for optical powers of greater than 1 W.
4 For connectorized component, operating temperature range is –5 – +75oC.
