The 1550nm externally modulated optical transmitter is designed exclusively for fiber optic communication. Its major function is to transform electrical signals into optical signals and transmit them across optical fiber. Externally modulated optical transmitters have a working wavelength of 1550 nm and employ external modulation technology, which means they use an external modulator to change the intensity or other properties of an optical signal in order to send an electrical signal. External modulation technology is more adaptable and efficient than direct modulation technology, making it suited for long-distance and high-speed data transfer.

PL1550T Externally Modulated Optical Transmitter combines a high linear LiNbO3 external modulator with an imported low-noise DFB laser. When the CNR is high, the optimal CTB and CSO are guaranteed by an excellent pre-distortion circuit. PL1550T 1550nm Externally Modulated Optical Transmitter has excellent performance that is the ideal choice for long-distance transmission and large area covered local networks.
