EFB KM53516 Keystone-moduuli LC Duplex OM3 Aqua kuitu-liitäntä

Aquamarine keystone modules are often mistaken for generic couplers, but the EFB KM53516 stands apart through its precision zirconia alignment sleeves and OM3-optimised multimode performance. This LC duplex module slips into any standard keystone wall plate or patch panel, instantly creating a clean fibre termination point without field polishing or splicing. The aqua housing follows the TIA-598 colour code for OM3, making it easy to identify high-bandwidth multimode links at a glance.

Highlights

• LC duplex keystone module for OM3 multimode fibre, colour-coded aqua for instant recognition
• Ceramic (zirconia) alignment sleeves ensure low insertion loss and stable mating over hundreds of cycles
• Fits standard keystone openings — ideal for wall plates, surface boxes, and modular patch panels
• Compliant with IEC 61754-20 and TIA/EIA-604-10 mechanical interface standards
• Dust caps included to protect ferrules when ports are not in use

In daily use

Installers appreciate how quickly the KM53516 snaps into a faceplate — no special tools required. The duplex LC footprint supports both transmit and receive fibres in a single module, keeping cable routing tidy in crowded enclosures. With insertion loss below 0.3 dB and return loss above 30 dB, it preserves signal integrity for 10G Ethernet and faster links over OM3 fibre. The polycarbonate housing withstands typical handling during installation and remains stable across a wide temperature range from -20 °C to +70 °C.
