What does CMX stand for on wire?
Outdoor rated cable (CMX) is a perfect solutions for installations that want to go in to outdoor spaces. They are waterproof, UV resistant and can even be directly buried.
Can CMX cable be used in walls?
CMX is a residential grade cable.
| Rating | Usage |
|---|---|
| CM, CMG, CL2 | In-wall rated; permitted in 1-2 family residential riser applications, or in riser with raceway/fireproof shaft; not permitted in plenums |
Can CMX cable be used indoors?
In residential applications the NEC Article 800.113 allows for CMX rated Ethernet cable to be used as indoor/outdoor cable without restriction assuming the following rules are obeyed: The cable OD (overall diameter) does not exceed 0.25”
Can you run cable and Ethernet cable together?
You can run ethernet cables next to electrical cables if the ethernet cable is shielded, but even then you should keep 8in between them. Non-shielded cables can lose data and bandwidth when run next to power cables. PoE cables run too close to power cables can cause heating and fires.
Is CMX a plenum?
CMP cables are plenum cables; these cables are used if networking must be done in air ducts. They can be used for commercial or residential spaces. They will not combust and cannot actually cause fires.
Can cat6 riser cable be used outside?
Cat 6, Cat 5, or Cat 5e Ethernet cables can be run outdoors to network computers with a local area network (LAN) between homes or other buildings. Although ordinary Ethernet cables can be used, the better option is to use the more expensive weatherproof Cat 6 cables.
Do I need shielded ethernet cable?
As with many things in the AV industry, there’s no hard and fast rule when to use shielded vs. unshielded cable. Next generation cabling systems that perform beyond 10 GB/s transmission speeds will require shielded cabling and components, which makes STP systems more future-proofed than UTP.
Which ethernet cable for outdoor use?
Cat6 Shielded Cable
Cat6 Shielded Cable is typically best for outdoor networking. This outdoor ethernet cable is best when placed underground.
What’s the difference between riser and plenum cable?
Usually, riser cables are installed in between the walls of buildings. They can also be installed in areas that do not pose danger in case of a fire. Plenum rated cable is a cable that is suited to go in the plenum spaces of buildings.
Is it OK to use Ethernet coupler?
It is OK to use unshielded Ethernet cable with shielded couplers. Do NOT use shielded cable with unshielded couplers as you may create an opportunity for interference on your cable run.
Can you run 2 Ethernet cables next to each other?
It will be fine to run them next to each other, especially for home use. Ethernet cables are designed to be very resistant to interference.
Is it OK to run cat6 and power together?
Its very simple; just don’t put your Ethernet cables near any of power cables. Run your data cables 10″ to 12″ from your power cables. For future updates, put your cables inside conduit so that you can pull more cables or replace cables in the future.
What is plenum Ethernet cable?
A plenum cable can simply be referred to an Ethernet networking electrical cable that is rated to be run in plenum spaces of buildings. Generally, this sort of space lies in between floors of a given building.
What makes wire plenum rated?
Plenum rated cable has a special insulation that has low smoke and low flame characteristics. Plenum cable is mandated to be installed in any “air handling” space. For example, most large office buildings use the ceiling to return air to the AC unit.
What is plenum air space?
In building construction, a plenum (pronounced PLEH-nuhm, from Latin meaning full) is a separate space provided for air circulation for heating, ventilation, and air-conditioning (sometimes referred to as HVAC) and typically provided in the space between the structural ceiling and a drop-down ceiling.
What’s the difference between plenum and non-plenum?
Thus, fire and building safety codes mandate plenum-rated cables be used in plenum spaces and air ducts. They can also be used in non-plenum areas. Non-Plenum cables, on the other hand, are much cheaper and not as fire-resistant. When burned, they release toxic fumes such as hydrochloric acid and dioxin.
What is a non-plenum space?
The entry goes on to explain that a non-plenum airspace contains air that doesn’t move, as opposed to circulating air in a plenum airspace. A non-plenum airspace can accidentally become a plenum airspace if ducts become damaged or disconnected. This is dangerous, as circulating air can feed a fire.
Can plenum cable be used in walls?
Can be used in walls and beneath floors. Useful when the fire code does not have any restrictions on cable type. Often used for patch cords and jumpers.
When should plenum cable be used?
If you have a large wall or ceiling return air grate; remove and see if there the air is channeled through sheet metal ducting. If there is no sheet metal duct; just the open ceiling or wall space, then you are required by law to use Plenum Rated cable.
Is riser better than plenum?
The higher fire resistance of plenum cables make them a lower risk in a building fire than riser cables (which are, in turn, safer than general-purpose cables).
