The 10G-CAB-05 .5 Meter Fiber Cable w/SFP+ Modules is designed for use with Luxul managed switches that have 10 Gigabit stacking ports. It is .5M long and provides a cost-effective short run alternative to using more expensive fiber-based SFP+ modules. It offers a plug-and-play method for stacking two Luxul switches and when multiple 10G-CAB-05 are purchased, can be used to stack up to up to 16 Luxul switches.
