The current loop is actually "proper" .
There are 3 parts to current loop
1) transmitter (switch)
2) receiver (opto coupler in dec stuff)
3) current source
You will have problems if things don't match. An active transmitter has to
connect to a passive receiver.

There is a DF11-F module that converts TTY to EIA and back again, 2 2-slot
cards, cable,e tc. (Page 4-80 in the peripheral handbook from 73-74). The
handbook did not indicate a specific PDP 11 from this time (05/10/35/40,
etc)
