Cable gender changer InLine 69927B — adapter for reversing connector polarity

IP68 protection:The fiber optic coupler reliably protects fiber optic connections from water, dust, and extreme temperatures—ideal for demanding environments.
Robust and durable:Made from resistant PA66 with a silicone seal—for a long service life even under demanding conditions.
Easy to install:Pre-assembled LC duplex sockets and tool-free screw connection enable quick and secure installation.
Versatile:Ideal for single-mode connections with LC duplex connectors – e.g., in outdoor installations, industrial environments, or network cabinets.
Standardized installation options: M20 thread size fits into many common housing openings and ensures flexible integration.

The InLine® LC fiber optic cable coupling is the ideal solution for anyone who needs reliable and permanently protected fiber optic connections in demanding environments. With protection class IP68, the coupling is ideal for outdoor use, in damp or dusty environments, and in extreme temperatures from -40 °C to +85 °C.
The housing made of robust PA66 plastic in combination with a high-quality silicone seal ensures a durable and resistant connection. The integrated LC duplex sockets enable a secure connection of two single-mode fiber optic cables with LC connectors (UPC or APC). The M20 thread allows the coupler to be easily integrated into standardized openings in housings or distribution cabinets.
Installation is quick and easy: the pre-assembled sockets, dust-protected housing parts, and screw connections are intuitively designed and can be assembled without additional tools. This means that the connection is not only mechanically stable, but also reliably protected against external influences.
Whether for industrial applications, professional network installations, or demanding outdoor scenarios, with the InLine® fiber optic coupling, you are on the safe side.

How to use

Install the coupling by inserting it into an M20-compatible opening in the enclosure or cabinet and secure it using the screw connection. Connect two single-mode LC cables (UPC or APC) into the pre-assembled LC duplex female sockets. Ensure seals and housing parts are correctly positioned to maintain IP68 protection. No special tools are required for assembly; follow standard fiber handling practices to avoid contamination of connector endfaces.

Recommendations

For reliable long-term performance, clean connector endfaces before mating, verify the cable diameter matches 2.9 mm, and install the coupling in an appropriate M20 opening. Avoid mechanical strain on the fiber cables and check seals after any maintenance or reinstallation.
