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

Fiber optic switches route an optical signal without electro-optical and opto-electrical conversions

Audio connectors are used to affix cables to other audio equipment, providing electronic signal transference and grounding protection

Audio amplifiers are used in circuits and systems to process audio signals

Digital audio systems electronically record and store audio signals such as voice, music, alarm, and security messaging for broadcast, editing, monitoring, and playback

Video, audio, and multimedia chips are IC chips designed for video, audio, and multimedia applications

Audio analyzers measure the noise and audio spectrum of output from an amplifier or a stereo

Audio amplifiers and preamplifiers are units that amplify a sound signal, which is then sent to a speaker or another amplifier

Audio transformers are involved in the transmission of voice or sound signals. They often require wide frequency bandwidth with low distortion and noise suppression

Audio visual service providers design, integrate, and install multimedia equipment for corporate, production, and broadcasting applications

Optical isolators are optical devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause feedback problems

Telephone components and accessories are used in telephone systems.

Audio transducers and buzzers are used in electronic equipment, toys and various warning devices as the sounding component

Optical manufacturing services design, fabricate, finish and test optical components and optical elements

Video and audio software is used to process audio and video signals. Applications can include motion analysis, security, ID systems, etc
