These are effectively a higher-performance version of a diplexer, typically with a narrow split between the two frequencies in question (typically around 2%-5% for a commercial two-way radio system). With a duplexer the high- and low-frequency signals are traveling in opposite directions at the shared port of the duplexer.
The diplexer is a different device than a passive combiner or splitter. The ports of a diplexer are frequency selective; the ports of a combiner are not. There is also a power "loss" difference - a combiner takes all the power delivered to the S port and equally divides it between the A and B ports. A diplexer does not.
A diplexer is to allow two signals to be carried over a single path - i.e. to provide two-channel multiplexing. Generally a diplexer consists of a pair of filters with non-overlapping pass-bands, so it implements frequency-division multiplexing. I agree that a device can be both a diplexer and duplexer - if it is a diplexer where the two ...
In same-band repeaters, isolation between transmitter and receiver can be created by using a single antenna and a device called a duplexer. The device is a tuned filter connected to the antenna. In this example, consider a type of device called a band-pass duplexer. It allows, or passes, a band, (or a narrow range,) of frequencies.
An orthomode transducer (OMT) is a waveguide component that is commonly referred to as a polarisation duplexer. Orthomode is a contraction of orthogonal mode . Orthomode transducers serve either to combine or to separate two orthogonally polarized microwave signal paths. [ 1 ]
There's a difference, of course, between ethnicity, nationality, and heritage -- but when it comes to general folks, it's hard to explain the distinction.

A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment ...
