Wireless systems consist of combined RF components such as transmitters, receivers, transceivers, filters, down / up converters, antennas and antenna positioners.

RF and wireless chips are integrated circuits (IC) that are designed specifically for radio frequency (RF), microwave, and other wireless communications or data transmission applications.

Laser drivers control and manage the operation of lasers used for switching in optical networks.

Wavelength division multiplexers (WDM) are passive devices that combine light signals with different wavelengths, coming from different fibers, onto a single fiber.

Specialty fiber optic components are specialty or proprietary products related to fiber optic systems.

Bit error rate testers are devices or procedures that measure the bit error rate (BER) for a specific transmission.
