Description
Overview
GAOTek optical fiber external transmitters are designed according to CATV standards. It modulates the CATV RF amplitude signal into a 1310 nm / 1550 nm optical signal and then transmits it to an optical node in the HFC network through a single-mode optical fiber. It is mainly used for TV signal medium-sized network transmission and can be used for many purposes.
