What is Inside the Combo Cable Modem Router?

Leave a comment

First off, know that there are two variations of the combo cable modem: the external and internal combo cable modem. In cases that relate to combo cable TV services, chances are they will incorporate a device called a set-top combo cable box. This type of combo cable modem device only requires your standard keyboard and mouse to gain internet access.

Upgraded versions of these devices (from standard combo cable system to digital combo cable) will be able to connect to the internet by default without needing to connect to the CATV. While best combo cable modem routers combos typically come in different shapes and sizes, depending on the ISP, all combo cable modems have the same set of essential components.

Coaxial Cables Explained

Leave a comment

A coaxial cable has a solid copper or copper-clad-steel centre conductor surrounded by a non-conductive dielectric insulating material. The dielectric is surrounded by foil shield/s and/or copper braid/s which form the outer conductor and also shield against electromagnetic interference (EMI). The outer conductor/shield is encased in a PVC jacket.

Most coaxial cables for video applications have a nominal impedance of 75 ohms. Their differing electrical and physical characteristics make it important to select the correct type of cable to suit the application.

Coaxial cables that conform to U.S. Government specifications are identified with an RG designation. The meaning of the individual components of the designation are:

If the letters A, B or C appear before the slash (/) it indicates a specification-modification or revision. As an example, RG 8/U is superseded by RG 8A/U.

Leave a comment

Multimedia Solutions cabling has always been committed to delivering safe and reliable cablings for critical comms system. We are proud to inform that our fire alarm cable (FAC Series) and Security Comms (SAC series) Cables are now UL Listed, complying to the FPLR / CMR standards critical for Alarm systems. These cables are also available in Low Smoke Zero Halogen sheathing to ensure minimum smoke density and toxicity when burnt.

Fire alarm cable (12 to 18 AWG; 1 or 2 pairs or more) are widely used in fire alarm or intercom systems. Security alarm cable (12 to 22 AWG; 1 or 2 pairs or more) are most suitable for applications such as security , intercom , broadcast and audio. Designed with PVC-CMR outer sheath provides much better fire performance over the commonly offered PVC outer sheath.

Both types of alarm cables comply to stringent flame retardant standard ie IEC 60332-1, low smoke IEC 61034, zero halogen and low acidity IEC 60754 , UL certified NEC FPLR & CMR .

Both alarm cables offered in both unshielded and shielded design. The unshielded version offered for low electromagnetic interference environment and, the shielded version is especially suitable for environment with high level of “white noise”. The alarm cables are twisted to minimize crosstalk interferences and are available in awg sizes up to multi pairs counts.
