FUSED COUPLER 980 NM
Fused Fiber Coupler
The Gooch & Housego fused coupler, 980 nm enables the accurate splitting and monitoring of pump power in 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 a wide variety of tap ratios, housing and connector options and can therefore be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds. Standard variants for 960 nm and 1060 nm may also be selected.
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 contact the sales office.

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.
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.
