physical layer issue.CRC is increasing rapidly.

with such high input errors and increasing crc values, this suggest a physical layer problem. you can also see that you recieve a lot of runts .this could be due to number of factors, faulty cable,Network noise due to near by electronics/Grounding,Fautly Transciever or adapter, fault at the TX side of line, etc bottom line check for physical layer issues.Network analyzer may help to pin down the problem source.

Ochuko,
Is this a new install? did you recently light up this fiber? We know it is SM fiber, thus there could be attenuation issues at the RX, maybe need to see the DB level verse the specifications and see if you are in-line !
please advise,

Please post your show controller POS interface, this should kind of give you where the errors are accuring, if you place a internal loop does the error stop? i would check the light level, then engage your ISP for H2H test( head 2 head)
