Length: 1.5m to under 2m This is a fiber optic cable. As shown in the image, the interfaces are ST on both ends, so please make sure you have the correct type. If your switch is CISCO, please check the SFP interface carefully. Other manufacturers also have specifications for fiber optic interfaces. I have four more of the same item, so if you want multiple, please comment. I will list them according to the quantity requested. The box appears to be dirty due to aging.
