## Summary description

The Tecline 90744 is a metallic LC/LC fibre optic adapter designed for single-mode applications. It ensures reliable connections in fiber optic networks, providing low insertion loss and high durability. Ideal for use in telecommunications and data transmission systems.

## Long description

The Tecline 90744 Metallic Single-mode LC/LC fibre optic adapter provides a compact, metal-housed coupling for joining two LC single-mode connectors. Designed for precision alignment of ceramic ferrules, this adapter supports standard single-mode optical fibres and delivers consistent low insertion loss and mechanical durability. Its metallic shell offers improved grounding and resistance to wear in installation panels, patch boxes, and outdoor enclosures where a stable optical connection is required.
Advantages
The metallic construction enhances mechanical strength and shielding while maintaining precise alignment for LC connectors, which helps minimize insertion and return loss. The adapter is compatible with standard single-mode LC plugs and is designed for repeatable connections with stable optical performance over many mate/unmate cycles. Its compact footprint allows installation in dense patch panels and small enclosures, and the durable materials resist deformation under normal handling and rack-mounted use.
Suitable for
 Telecommunications racks and central offices
 Data centre patch panels and fibre distribution frames
 FTTx termination points and subscriber installations
 Laboratory test benches and fibre performance testing
 Outdoor enclosures with proper environmental sealing
Key specifications
 Connector interface: LC to LC duplex format
 Mode: single-mode (SM)
 Housing material: metallic shell for enhanced durability
 Ferrule alignment: precision ceramic sleeve
 Typical optical performance: low insertion loss and low back reflection (single-mode optimized)
 Mounting: panel or adapter plate compatible, compact form factor
 Durability: designed for multiple mate/unmate cycles
How to use
Install the adapter into the appropriate panel cut-out or adapter plate, ensuring the adapter is seated securely and aligned with adjacent modules. Insert LC single-mode connectors gently into each side until a positive latch is felt; avoid excessive lateral force to preserve the ceramic alignment sleeve. For duplex connections, ensure correct orientation of the duplex clip or housing to maintain transmit/receive alignment. When removing connectors, depress the connector latch fully and withdraw in a straight motion to prevent damage to the ferrules or sleeve.
Usage recommendations
For optimal performance, keep connector endfaces clean and inspect them before mating using an appropriate fibre inspection tool. Use dust caps when connectors are unmated and follow standard single-mode handling practices: avoid bending fibres below specified bend radii, secure patch cords to reduce mechanical strain, and perform optical testing after installation to verify insertion loss and return loss are within expected limits.
