| Residential Structured Wiring Its
not just a home anymore. It's a place to get things done-to stay connected
with the world. Its a place to be protected-to be monitored for security
and efficiency. Its a place to be entertained-to have a full lineup of
HDTV video, digital audio, and interactive choices at one's command.
Select from a premier line-up of UL-3 rated cables suited for in-wall
installation: Residential Composite, Cat6 cable, Cat5e cable and RG6
bulk cable manufactured by Avaya, Belden, Berk-Tek, Commscope, Superior Essex. |
Office Structured Wiring If your
business depends on networking count on us for all of your structured
wiring Cat6 and Cat5e bulk cable needs. The Cat6 and Cat5e UTP cables we carry allow
voice-data convergence and support for Gigabit Ethernet. Choose from
industry leading copper solutions from Avaya SYSTIMAX GigaSPEED, Avaya
SYSTIMAX PowerSUM, Belden, Berk-Tek LANmark, Commscope
and Superior Essex. Available in both plenum and non-plenum Standards supported:
10/100/1000BaseT, 155/622 ATM, 568A/B. Wire and cable specifications available. |

•
| Cat3
(Category 3) - Unshielded twisted pair with 100 ohm impedance
and electrical characteristics supporting transmission at
frequencies up to 16 MHz. May be used with 10Base-T, 100Base-T4,
and 100Base-T2 Ethernet. (Obsolete)
| |
•
| Cat5
(Category 5) - Unshielded twisted pair with 100 ohm impedance
and electrical characteristics supporting transmission at
frequencies up to 100 MHz. May be used with 10Base-T, 100Base-T4,
100Base-T2, and 100Base-TX Ethernet. May support 1000Base-T, but
cable should be tested. (Superceded by Cat5e)
|
|
•
| Cat5e
(Category 5e) - "Enhanced Cat 5" exceeds Cat 5
performance. Very similar to Cat 5, it has improved specifications
for NEXT (Near End Cross Talk), PSELFEXT (Power Sum Equal Level
Far End Cross Talk), and Attenuation. May be used for 10Base-T,
100Base-T4, 100Base-T2, 100BaseTX and 1000Base-T Ethernet. (Minimum
acceptable wiring grade)

•
| Cat6
(Category 6) - Unshielded twisted pair with 100 ohm impedance
and electrical characteristics supporting transmission at
frequencies up to 100 MHz. May be used with 10Base-T, 100Base-T4,
100Base-T2, and 100Base-TX Ethernet. May support 1000Base-T, but
cable should be tested.
