Lightwin LKUP DSC-DSC MM OM3 Duplex SC Fiber Optic Coupler, Ceramic Sleeve, Metal Housing, Aqua, Panel Mount

In a busy data center, a network technician needs to join two duplex SC multimode OM3 patch cables quickly and reliably. The Lightwin LKUP DSC-DSC MM OM3 coupler snaps into a standard panel cutout, aligning the ceramic sleeves to keep insertion loss below 0.2 dB. Its metal housing with flanges ensures a secure, long-lasting connection for high-speed 10G/40G/100G Ethernet links.

Key specifications

• Connector type: Duplex SC to Duplex SC
• Fiber mode: Multimode OM3 (aqua sleeve)
• Sleeve material: Ceramic (zirconia)
• Housing material: Metal with panel-mount flanges
• Insertion loss: < 0.2 dB typical
• Mating cycles: > 500
• Operating temperature: -20°C to +70°C
• Compliance: IEC 61754-4, TIA/EIA-604-3, RoHS, REACH

Why choose it

This coupler is built for demanding environments. The ceramic sleeve provides precise fiber alignment, minimizing signal loss and back reflection. The metal housing offers durability and EMI shielding, while the aqua color coding instantly identifies OM3 multimode compatibility. Panel-mount flanges allow easy installation in patch panels, wall plates, or enclosures.

Ideal use cases

• Data center cross-connects and interconnects
• LAN and SAN backbone patching
• Telecommunications distribution frames
• Fiber-to-the-desk applications
• Temporary link extension in testing labs

Good to know

The coupler is compatible with all standard duplex SC connectors, including UPC and APC polished ferrules (APC may require adapter with angled alignment). It supports OM3 multimode fiber for distances up to 300 m at 10G and 100 m at 40G/100G using SR4 optics. For best performance, clean connectors before mating and use dust caps when not in use.
