DS92LV2421: How to insert galvanic isolation in channel-Link II transmission line

Part Number: DS92LV2421


My industrial customer is considering image transmission using channel - Link II.
The data rate the customer is thinking is about 1.8 Gbps.
The transmission distance is about 40 m or more.
Devices are DS92LV2421 and DS92LV2422.

We believe that DS15BA101 and DS15EA101 are also required as a cable extender that realizes transmission of 40 m or more.

The customer's challenge is the need to isolate the board and cable.
Can you tell me if there is a solution to isolate such a high speed data line?
