Strange CAN BUS waveforms when using the PCAN optoadapter

Hi all,

I have 3 devices in a CAN bus system.
1st device is isolated from the others by using the PCAN optoadapter.
CAN BUS data rate is 250kB/sec
1st sends 4 TPDOS at 100ms.
2nd device sends 1 TPDO at 10ms
3rd device sends 4 TPDOs at 100ms.
Cable length 2-3meters.
