description

Specific coupler for sensor applications where the directivity is the most important characteristic.

These couplers can be used at all wavelengths guided by the fibre with almost no change in coupling ratio. Due to the technology based on wave front division, they are only slightly sensitive to modal injection.

   
 
 

TECHNICAL SPECIFICATIONS

Product made to be used in round trip configuration.
Fibers are protected with black loose tube 900µm in order to avoid noise by external light.
One port is dedicated for injection and it is identified by a blue marking.

Note: There is no established standard for multimode components metrology. Values can vary substantially according to measurement bench set up (laser, diode, detector, etc.) Customers must check adequacy of performances on their system.
