EFB Electronics Acoplador de fibra ótica LC Duplex OS2 monomodo, caixa de plástico azul, formato SC simplex, uma peça

Network technicians and data centre managers often need a reliable, low-loss interconnect for single-mode fibre links in patch panels and wall outlets. The EFB Electronics LC-Duplex OS2 coupler fits into standard SC-simplex cut-outs, letting you join two LC-terminated OS2 cables with precision alignment inside a compact blue plastic body. Its one-piece housing means fewer parts to handle during installation, and the zirconia ceramic sleeves keep insertion loss low for stable gigabit and 10G links.

Key specifications

• Connector type: LC-Duplex to LC-Duplex (female-to-female)
• Fibre type: OS2 single-mode (9/125 µm)
• Housing material: Plastic, blue
• Mounting: Fits SC-simplex panel cut-outs
• Design: One-piece body for quick snap-in installation
• Sleeve material: Zirconia ceramic for precise ferrule alignment
• Insertion loss: ≤ 0.2 dB typical
• Durability: ≥ 500 mating cycles

Why choose it

This coupler simplifies fibre management by adapting LC duplex connections to existing SC-simplex infrastructure without replacing panels. The blue colour coding follows common OS2 single-mode identification, reducing the chance of mixing multimode and single-mode links. The one-piece design eliminates loose sleeves or clips, so it stays intact even in high-vibration environments. With zirconia sleeves, you get consistent low loss across repeated connections, which is critical for long-haul or high-speed backbone links.

Ideal use cases

• Terminating OS2 fibre runs at patch panels in data centres
• Connecting LC-to-LC single-mode jumpers through wall plates
• Upgrading legacy SC-simplex panels to accept LC duplex connectors
• Creating test points in FTTH distribution boxes
• Joining two pre-terminated OS2 cables in a protected enclosure

Good to know

The coupler is designed for OS2 single-mode fibre, which supports wavelengths of 1310 nm and 1550 nm. It is not intended for multimode fibre. The blue plastic housing is flame-retardant and RoHS compliant. For best performance, clean connector end faces before mating. The coupler is sold individually; order quantity should match the number of ports needed.
