Solution for my case, is change the Patch cords to "OM3 - Multimode (MMF)" Specs:

Model: Duplex Fiber (2 Fibers)
Connector-Polish A: LC-UPC
Connector-Polish B: LC-UPC
Polarity Type: A (Tx) to B (Rx)
Connector ferrule: Zirconia ceramic
Fiber Type: MMF - OM3 50/125m Multimode
Cable Length: 3 meters
Cable Diameter: 2.0mm
Cable Coating: LSZH (Low smoke zero halogen), Aqua Color.
Supported Data Rate: 1G~40Gbps
Wavelength: 850/1300nm
Maximum Insertion Loss: 0.3dB maximum (Typically loses: 0.22 dB)
Return loss: 20dB
Loss per km: 3.0 dB/km at 850nm | 1.0 dB/km at 1300nm

Topology Now 100% OK, No More Errors on Logs Report from Dell SC4020 or Switch (Port Flap - Up/Down):
