3、 Equipment installation and activation
Unpacking inspection
Open the packaging box and confirm if the listed materials match the packing list. If there are any defects, please contact us promptly.
Installation steps
After removing the device, place it steadily on a horizontal desktop or fix it on a rack;
Fasten the nuts of the two sets of screws that fix the equipment onto the ear holes on both sides of the rack, and then thread the bolts through the ear holes of the equipment and the rackEarholes, finally riveted together with nuts;
Input the signal that needs to be compensated from the optical interface on one end of the device, and output the signal from the optical interface on the other end of the device.
4、 Common problems and solutions
1No signal output: Please check if the optical port is properly connected and if the wavelength of the optical signal is within the operating wavelength range of the device. If it cannot be solvedPlease contact us promptly.
