The YFZ, SFZ, YFP and SFP branch dispensers are passive distribution devices in the CATV cable transmission network. Aluminum and zinc die-casting shell, surface tin and bottom cover tin sealing process, radiation prevention, anti-interference ability, built-in PCBA for superFM design, the electrical performance index is better than the national standard. Metric and British F-head interface, super small design, light weight, easy to attach. YFZ and YFP are quadrilateral in and out, and SFZ and SFP are top in and out.
◆5-1000 MHz electrical performance is better than the national standard, each port capacitor isolation;
◆ -7 Cable core or Φ 1.68mm round copper wire is continuously straight for 20 times, the spring sheet is unchanged, and the contact performance with the inserted core wire is unchanged.
