Key Features * Very precise coupling ratio adjustment -- from 0 to 99% The F-CPL-VP polarization main- taining (PM) version preserves the orientation of the fast and slow axes throughout the tuning range, while maintaining low crosstalk between the polarization states. Both coupler versions are offered at either 1310 and 1550 nm. Other wavelengths are available -- please call Newport. * Low insertion loss * High polarization isolation * PM and non-PM types available Ordering Information Typical Price 0-80% 0-99% Model Model Code Description F-CPL-V8013 10 0-80% Coupler, 1310 nm Insertion Loss [dB] F-CPL-V8015 20 0-80% Coupler, 1550 nm Polarization Isolation [dB] -20 F-CPL-V9913 30 0-99% Coupler, 1310 nm F-CPL-V9915 40 0-99% Coupler, 1550 nm Dimensions [mm] 25 x 38 x 63 (Micrometer - 28 long) F-CPL-VP8013 15 0-80% PM Coupler, 1310 nm F-CPL-VP8015 25 0-80% PM Coupler, 1550 nm F-CPL-VP9913 35 0-99% PM Coupler, 1310 nm F-CPL-VP9915 45 0-99% PM Coupler, 1550 nm 0.05 Minimum Coupling EDUCATIONAL KITS PM Standard Coupling Ratio Fiber Optic Connector Options Please use the following Model Number to order our variable couplers with connectors: F-CPL-VP-OPT- Model Connector Code Style Code 25 45 55 65 75 Note: For connector price information, see page 5-34.

The coupling ratio can be continuously varied by adjusting a micrometer which changes the separation of the two fiber cores. FIBER OPTIC COMPONENTS FROM NEWPORT Variable Ratio Couplers Maximum Coupling The coupling ratio is varied by changing the fiber separation. Variable PM coupler with adjustable coupling ratio from 0 to 80%, optimized for 1550 nm, with FC/APC Connectors. Web: www.newport.com 5-9
