RF phase shifters are twin-ported devices that alter the phase of an output signal in response to an external signal.

Power over Ethernet (PoE) splitters receive a unified PoE signal (data and power), and then separate the data and power onto two different lines for non-PoE devices

Telephone components and accessories are used in telephone systems.

Fiber optic couplers are optical devices that connect three or more fiber ends, dividing one input between two or more outputs, or combining two or more inputs into one output.

RF power dividers and power combiners are circuits that accept an input signal and deliver multiple outputs equal in phase and amplitude.

Plate beamsplitters are semi-mirrors, which reflect part of the incident energy (absorb a relatively small part) and transmit the rest.

Nonpolarizing cube beamsplitters provide a true 50/50 split regardless of the incoming polarization.
