It is constructed of robust materials compatible with the platform's thermal management system and provides a secure fit to prevent dust ingress, enhancing system reliability. The panel interfaces directly with the chassis slot. ## Function The single-slot filler panel is a passive component designed for use in the LTB series chassis, serving to physically occupy an unused slot within the platform. It maintains proper airflow management and electromagnetic compatibility (EMC) by blocking the opening and preventing the ingress of dust and other contaminants. ## Platform Designed for integration into EXFO LTB series modular test platforms as a blank cover panel that occupies unused single module slots in the chassis rack system. Maintains proper airflow patterns and electromagnetic shielding integrity within the test platform enclosure while providing aesthetic uniformity across the front panel interface. Enables field technicians to configure custom test setups by selectively populating only required test modules while maintaining chassis structural integrity and thermal management specifications. ## Application Passive mechanical component used to cover vacant slots in EXFO LTB optical test platforms, maintaining internal airflow, preserving cooling efficiency, and providing protection against dust or contamination. Ensures chassis integrity, proper ventilation, and prevents electromagnetic interference in modular test environments. Essential for system maintenance when not all available slots are populated with active test modules. ## Accessories Designed to cover empty slots in LTB-1, LTB-2, LTB-8, and LTB-12 mainframes. Maintains proper airflow and thermal conditions within the LTB chassis. Compatible with all LTB series platforms. Secured with screws to the mainframe chassis. No electronic interfaces or connectors as this is a passive mechanical component. ## Interface Blank passive slot filler panel for empty slots in LTB series optical test platforms. No electronic interfaces or connections. Maintains proper airflow and prevents dust ingress. Compatible with LTB-1, LTB-2, LTB-8, and LTB-12 mainframes. Mechanical interface only, mounting via standard slot connection mechanism. No power, data, or optical interfaces. ## Images - - - -
