A technician is running a new cable connection from a cable modem to a coaxial wall outlet installed by the ISP. Which connector type is used to terminate this type of cable?
- AF-connector
- BST connector
- CRJ11 connector
- DBNC connector
Show answer & explanationAnswer & explanation
Correct answer: A. F-connector
F-connectors are the threaded screw-on connectors used to terminate RG-6 coaxial cable for cable modem and cable TV installations. BNC connectors are older twist-lock coaxial connectors typically used in networking or video equipment, not modern residential cable service.
Why the other options are wrong
- B. ST connectors are used to terminate fiber optic cable, not coax.
- C. RJ11 connectors are used for analog telephone lines, not coax.
- D. BNC connectors use a twist-lock design and are found on older coax networks or video gear.
F-Connector
A threaded, screw-on coaxial connector used with RG-6 cable for cable television and cable internet service.
- Used by cable modems and cable TV boxes
- Threaded design provides a secure, weatherproof connection
- Different from BNC, which uses a twist-lock mechanism
Memory trick: F for fastened-on, screw it tight for cable TV.
