## Long description

The EFB Elektronik B71901L12OM3 fibre optic adapter is a multi-mode LC connector module designed for structured cabling and network patching installations. Sized to fit standard rack and panel mounts, it combines an Aqua and Grey finish to indicate multi-mode fibre compatibility and to match common data-centre colour conventions. The adapter supports reliable optical mating between LC-terminated multi-mode cables and helps maintain low insertion loss in short- to medium-distance network links.
Advantages
This LC Aqua Grey multi-mode adapter delivers consistent alignment for duplex LC connectors and reduces back reflections and insertion loss when used with compatible multimode fibres. Its compact form factor and standard panel width make it simple to integrate into patch panels, chassis or wall-mounted frames. The colour coding improves visual identification of multi-mode links, speeding installation and maintenance tasks.
Suitable for
 Data centre patching and fibre-management panels
 Local area network (LAN) multimode connections
 Telecommunications closets and equipment racks
 Short- to medium-distance optical links within buildings

How to use
Install the adapter into a compatible rack-mounted patch panel or chassis slot sized for the module width and height. Insert LC-terminated multimode fibre connectors into the adapter ports until a firm click indicates full engagement, observing the duplex orientation for transmit and receive alignment. When removing, depress the connector latch and withdraw straight to avoid stressing the ferrule. Inspect fibre endfaces and clean with approved optical cleaning tools before mating to ensure optimal signal transfer.
Usage recommendations
Use this multi-mode LC adapter with matching multimode cables and transceivers; follow standard fibre-handling procedures, keep bend radii above manufacturer minimums, and perform endface cleaning and inspection before connection. For permanent installations, label ports according to your cabling scheme and verify link performance with an optical test set after installation.
