An optical transmitter is a unit that converts electrical signals into optical signals, launching modulated light into a fiber for transmission over a communication link.
An optical transmitter is the device at the sending end of a fiber optic link that converts electrical signals into light. Using a light source such as a laser or LED, it modulates the light to encode the data and launches it into the optical fiber. The transmitter performs the electrical-to-optical conversion that begins fiber communication.
The characteristics of the transmitter, including its wavelength and output power, must be matched to the fiber and the receiver for the link to perform well. The light it launches travels through the fiber to the receiving end, so the quality of that launched signal and the fiber carrying it both affect the performance of the link.
In commercial and industrial fiber systems, optical transmitters work with fiber and receivers to carry data, video, and communication. The fiber and its connections must preserve the optical signal launched by the transmitter so that it reaches the receiver with its information intact.
Because the transmitter's wavelength and output must suit the fiber and receiver, matching it to the rest of the link is essential, and the fiber carrying its launched light must preserve the signal so that it arrives intact at the receiving end.
At Windy City Wire, the focus on fiber optic cable for commercial communication supports the links that optical transmitters begin. Supplying quality fiber matched to the operating wavelength helps ensure that the light a transmitter launches reaches its destination with its signal preserved.
