Subscriber socket. GMF 351 Multimedia - description
GMF-35x series multimedia sockets are designed for MATV systems in which the return channel is used – data transmission service (Internet) and VoIP telephony are offered. The socket distributes the sum of signals transmitted in coaxial cable to the appropriate outputs: R (FM radio receiver), TV (TV receiver), D – DATA (cable modem). The housing design of the GMF multimedia socket allows it to be installed in a plastic OGF housing (mouse). Thanks to this, it can be used in cable TV installations as an end subscriber outlet. GMF series multimedia sockets are designed for indoor use. Full operating frequency range 5-862MHz. Distribution of signals into separate, dedicated outputs: R/TV/DATA. Equal attenuation of signal losses for both transmission directions in the DATA path. Effective interference blocking from the output side in the direction of the return channel >30dB. Robust, die-cast ZnAl housing. Very high shielding factor. Simple installation and secure connection – "F" sockets. Aesthetic housing of the "mouse" type. TECHNICAL DATA: Stop band: RTV->EC: 5-65 MHz
