DUAL WINDOW COUPLER
Fused Fiber Coupler
Gooch & Housego’s dual window coupler provides new levels of performance and reliability for two-window couplers.
The coupler enables coupling and splitting simultaneously over the 1310 nm and 1550 nm windows.
Within optical networks the ultra-low insertion loss of the wideband coupler makes it easier to meet stringent optical power budgets. Furthermore the component is designed for high reliability and low FIT rates, through robust fusion and advanced component packaging.
Components are available in a variety of package styles to suit a wide range of applications, including optical networking. Wavelengths other than 1310/1550 nm are also available as a custom product. Please contact us to discuss your specific requirements.

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 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.
