Product description:
TELEVES 231201 is an OUTDOOR Optical Node for both FTTB (Fiber-To-The-Building) and FTTC (Fiber-To-The-Curb) facilities, where it becomes the link between the end of the optical network trunk and the end user for delivering TV signals via coaxial cable. Only for forward channel transmission. By means of a LED graphical scale, you get the optical level information of the forward channel at the input of the device. It is equipped with separate stages of RF and IF, with controls for equalisation and attenuation. A hybrid circuit in its output stage contributes to achieve a high output power. Features a test output to avoid cutting services to the user in testing operations.
