GAO’s small form-factor pluggable known as SFP GE-FX and DWDM transceivers are types of optical transceivers used in networking and telecommunications. GAO’s SFP GE-FX transceivers are specifically designed to support Gigabit Ethernet connectivity over fiber optic cables. Our product use laser technology to transmit and receive data signals over the fiber optic medium, allowing for high-speed data transmission over long distances. DWDM which is the dense wavelength division multiplexing is used to increase the capacity of fiber optic networks by transmitting multiple wavelengths of light (channels) simultaneously over a single fiber. Each wavelength can carry its own data stream, effectively multiplying the capacity of the fiber. 


GAO’s SFP GE-FX & DWDM transceivers comprise of laser diode, photodiode, transmitter, receiver, optical connector, EEPROM (Electrically Erasable Programmable Read-Only Memory), digital diagnostic monitoring (DDM), and wavelength-specific components (DWDM Transceivers).
