Upstrem SNR low on Fiber Optic


I was told by my lineman that my line is converted to Fiber Optic, but looking at my stats I get very low Upstream SNR. Does upstream SNR stays like this ? I have 4 mb connection. Also I was facing disconnection issue yesterday 5 to 10 disconnection in 1 hour.

Having this low SNR, does this mean I still have copper line.

Yes, it stays like this when you have 4 Mb connection.

When lineman says you have fiber optic he most likely means the cable that connects your modem to nearest cabinet (MSAG) is copper while from that cabinet to exchange office is fiber optic cable.

How can i check my internet connection speed?
