FUSED PUMP SIGNAL WDM 980 nm
Fused Fiber WDM
The Gooch & Housego fused pump signal WDM, 980 nm multiplexes signal and pump power in 980 nm, 960 nm or 1060 nm-pumped erbium doped fiber amplifiers.
G&H proprietary manufacturing technology provides uniquely low excess loss and wavelength dependence, along with low polarization and temperature dependence for all ports. The ultra-low loss of these components promotes high efficiency of use of pump power and low noise figure.
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 allow for 960 nm,980 nm or 1060 nm pumping and C, L or C+L signal bands.
Reliability is assured through qualification to Telcordia GR-1221, with a field proven FIT rate of <1.
For the sub-miniature version of this product please refer to the sub-miniature pump signal WDM data sheet.

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 fibre 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.
