Hi Team,

According to the data sheet, this device supports 130m cable length.

The standard cable length of 10BASE-Te, 100BASE-TX and 1000BASE-T is 100m.

What technology enables this product to support 130m?

Hi Atsushi-san,

The TDR diagnostic test feature could support up to 130m.

Hi Hillman-san,

Thank you for your reply.

I understand about TDR diagnostic test.

However, just because the cable diagnosis supports 130m does not mean that communication at 130m is possible.

We believe this product has technology such as noise reduction and signal conditioning that allows communication up to 130m.

What technology does this product use to enable communication up to 130m?

Hi Atsushi-san,

Due to the US Christmas and New Year holiday, the response to your question will be delayed. Sorry for the wait and any inconvenience it may cause.

Thanks,

David

Hi Atsushi-san,

I double check with the team internally. It seems like we can reach 130m with two DP83867 and CAT5E shielded cable.
