LogiLink NK0031 Keystone LC-Duplex Multimode OM3/OM4 Fibre Optic Coupler, Aqua

Where standard fibre couplers simply bridge connections, the LogiLink NK0031 Keystone Module refines the link with zirconia ceramic alignment sleeves and a snap-in footprint that fits any standard keystone cutout. This LC-Duplex adapter in aqua is built for OM3 and OM4 multimode networks, delivering low-loss performance in patch panels, wall outlets, and data centre cabling.

Highlights

• LC-Duplex to LC-Duplex keystone coupler for multimode fibre
• Supports OM3 and OM4 laser-optimised fibre (aqua colour code)
• Zirconia ceramic sleeves ensure precise alignment and durability
• Snap-in mounting for standard 19.2 x 14.9 mm keystone cutouts
• Insertion loss below 0.3 dB; return loss above 30 dB
• UL 94V-0 flame-retardant ABS housing
• RoHS and REACH compliant; meets TIA/EIA-568-C.3 and IEC 61754-20

In daily use

Install the NK0031 in seconds: press it into a keystone wall plate, patch panel, or surface-mount box. The LC-Duplex ports accept standard multimode connectors, and the ceramic sleeves maintain consistent optical alignment even after hundreds of mating cycles. The aqua housing instantly identifies OM3/OM4 multimode links, simplifying moves, adds, and changes in high-density environments.
