I have a Cisco 2960S which connects to a core 4500X switch. When I first inserted fiber cables the 2960 was having a link flap issue. That was resolved by using a different sfp module. However there is now a high input error rate. Not just in the 2960, but the port in the core switch is also having a high rate of input error.
This is from the 2960S
