A fiber optic transceiver is a device that uses fiber optical technology to send and receive data. The transceiver has electronic components to condition and encode/decode data into light pulses and then send them to the other end as electrical signals. To send data as light, it makes use of a light source, which is controlled by the electronic parts, and to receive light pulses, it makes use of a photodiode semiconductor.The NWF4010H is a HDMI fiber optic transceiver, and the technology is digital uncompressed. It transmits the HDMI signal data of 1920X1080P@60Hz without delay, uncompressed and no lost. The wavelength can be 10G.It is unlike the normal analog optic transceiver transmit badly and unstabitily. The case can be stand alone or U rack mount
