I dont see why the fibre/copper demarcation would be significant.
Read in another thread that the CLI is a simple modem signal sent down the copper, it cannot be sent down the fibre in that manner so the equipment in big green cabs had to be capable of creating CLI signals. Some Cable infrastructure builders cut corners and bought cheap equipment that did not do this.
