We get asked a lot of questions. And there's a lot that don't get asked. If you want to know anything about Cable & Fiber just give us a call, or send us an email. We'll get right back to you.

Q: What’s the difference between CAT 5E & CAT 6?

A: CAT5E is rated to 100 MHz (MHz stands for megahertz), CAT6 is rated to 250 MHz. Both can have varied MHz levels but these are TIA/EIA minimum parameters for each type.

Q: How many CAT 5E cables can you fit in a conduit?

A: This is based on the cable diameter.

Q: What cable certifications do you have?

A: MyOffice holds the following certifications:

  • Panduit PCI (Panduit Certified Installer)
  • Berk-Tek
  • Superior Essex
  • Mohawk

Q: Do you offer warranty for your services?

A: Yes, up to a 25 year warranty.

Q: What is a Plenum ceiling?

A: According to the National Electric Code (NEC) a plenum is a "compartment or chamber to which one or more air ducts are connected and [ [ ]which] forms part of the air distribution system." In other words, the open space above your ceiling extends above other rooms in the same building or is open to ducts that connect it to other parts of the building. In a plenum ceiling air can circulate through the air ducts to the whole building.

Q: If I have a Plenum ceiling how does that affect my cabling needs? (What is the difference between PVC and Plenum rated Cable.)

A: PVC cable is the most common type of cable used today and consists of a chemical compound called Poly Vinyl Chloride. If a fire occurs, burning PVC cable can emit large quantities of dense black toxic smoke, and significant amounts of hydrochloric acid. If you have a Plenum ceiling, having PVC cable in the ceiling during a fire would cause a concentration of these fumes to be spread throughout the building. Exposure to these fumes could then hinder the safe evacuation of persons in the vicinity and result in increased fatalities. Plenum Rated Cable has a special coating on the wire, which causes it to burn at a much higher temperature and emit fewer fumes than conventional PVC. As a result, the National Electric Code (NEC) requires that only plenum rated cables be installed in plenum air spaces.

The chief difference when planning cabling for a facility with a plenum ceiling is to know that plenum cable is more expensive than PVC so make sure when you're getting estimates that they are all for plenum cable.

Q: Are you licensed & insured?

A: Yes, we hold our C-7 in house, CA Lic #827569 and we are fully insured and bonded.

Q: What is the maximum horizontal distance from the Telco closet to the workstation?

A: The maximum horizontal distance per TIA/EIA-586B.1:

  • 295 ft (90 meters),
  • 33ft (10 meters) total for patch cords (Station side + Telco Room side)
