Long reach interfaces use duplex LC connectors with all optical lanes multiplexed with WDM. After the encoding stage, the signals are multiplexed and sent out along the communication network. Because of the high complexity with modern wavelength-division multiplexed signals. Digital holograms can be numerically multiplexed and demultiplexed for efficient storage and transmission. The station's digital signal is multiplexed. The Line 21 data stream can consist of data from several data channels multiplexed together. Since the interfaces are "logical", many interfaces can be multiplexed onto the same transmission line. All kinds of digital communications can be multiplexed or encrypted at will. The industry soon developed and evolved with multiplexed T1 transmission schemes. Soldering components can also be more time-consuming than for multiplexed LED arrays. The upgrades made possible by the multiplexed coaxial cable were designated Caesar Phase III. In either designation, these channels are multiplexed together and sample at 8000bit/s. Between 2009 and 2015, the station had not multiplexed its channels. As of 2019, a channel of WWOR's programming is no longer multiplexed with WNYW. The result was a single machine that could be multiplexed among many users.
