An electronic apparatus having an optical communication capability of the present invention has a casing 10 and optical filters 12 and 13 for screening an infrared beam emitting/receiving device 25. The optical filters 12 and 13 each has a particular screening characteristic. The filters 12 and 13 are selectively removably fitted in a beam input/output window 111 formed in the casing 10. With these filters 12 and 13, it is possible to use one of the filters 12 and 13 matching the varying environment, and therefore to intercept optical noise lying in a broad wavelength range.
Appareil électronique à capacité de communication optique, comprenant un boîtier 10 et des filtres optiques 12 et 13 pour protéger un dispositif d'émission/réception de faisceaux infrarouges 25. Les filtres optiques 12 et 13 ont chacun une caractéristique de protection particulière. Permutables à volonté, ils s'adaptent dans une fenêtre d'entrée/sortie de faisceau 111 formée dans le boîtier 10. Il est donc possible de les interchanger en fonction des conditions ambiantes et d'intercepter ainsi le bruit optique sur une large plage de longueurs d'onde.
