FUSED PUMP SIGNAL WDM 1480 nm
Fused Fiber WDM
The Gooch & Housego fused pump signal WDM, 1480 nm multiplexes signal and pump power in 1480 nmpumped erbium doped fiber amplifiers.
G&H proprietary manufacturing technology provides uniquely low excess loss, along with low polarization and temperature dependence for all ports.
These high performance parts are available in many wavelength configurations, housing, fiber and connector options. They can therefore be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds.
Wavelength configurations are 1480 nm–C band and 1480 nm–L band.
Key Features
• Ultra-low typical <0.05 dB excess loss
• Wide range of regular parts available
• High power handling
Applications
• C or L-band pump/signal multiplexing
• 1480 nm pump rejection
• Fiber lasers

Operating/storage temperature range2
-40 – +75°C/-40 – +85°C
1 Measured reference port P3 input for signal wavelength, P2 input for pump wavelength and P1 input for signal and pump wavelengths.
2 For connectorized component, operating temperature range is –5 – +75ºC.
3 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.
4 The performance and reliability of optical connectors is not guaranteed for optical powers of greater than 1 W.
