TELECOMMUNICATION ASSOCIATIONS• EIA (Electronic Industry Association) - The standards address commercial building cabling for telecom products and services. The three standards are formally titled ANSI/TIA/EIA-568-B.1-2001, -B.2-2001, and -B.3-2001.

•TIA (Telecommunications Industry Association) – A global trade association headquartered in the United States that represents about 600 companies. TIA helps create universal networking standards for the telephone, data and the convergence of these industries.

•BICSI (Building Industry Consulting Services International) - The organization has membership in nearly 100 countries. This organization's certifications are considered the defacto certification for cable installers and designers who specialize in complex voice/data cable layouts.

BANDWIDTH

FIBER OPTIC CABLE

Fiber Optic Cable bandwidth varies from system to system . The end-to-end bandwidth of a fiber system is related to the respective bandwidths of its component parts.

Essential elements of end-to-end bandwidth are:

• Transmitter (type and wavelength)

• Fiber Optic Cable (distance)

COPPER

15 YEARS AGO

• Cat3 – 16 Mhz (Telephone)

• Cat4 – 20 Mhz (obsolete)

• Cat5 – 100 Mhz (obsolete)

TODAY

• Cat5e – 100 Mhz+ (VoIP)

• Cat6 – 200 Mhz (Gigabit)

• Cat6A – 550 Mhz (10Gigabit))

• Cat7 – 600 to 700 Mhz (M.Media)

Page 15: Network Technology Presentation   Bvh V01

CATEGORY 5e/6• CAT5e easier and less expensive to install than CAT6

but no “Headroom” for Gig (BVH recommends Min.6)• Will not support upcoming Technologies (10G)• 3-5 years away from the end of its lifespan

• Latest standard UTP cable (Supports 10G)• Difficult and time consuming to install• Very sensitive

EMI Temperature

CATEGORY 6A

CATEGORY 7• Shielded Cable•Category 7 is around the corner……

POWER OVER ETHERNET

802.3af up to 12.95Watts over UTP

The IEEE 802.3af PoE standard (ratified June, 2003) provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA) to each device. Only 12.95 W is assured to be available at the powered device as some power is dissipated in the cable.

Power Options

• Midspan (hard-wired)

• Within switch (auto-sensing)

Equipment using• IP Phones

• Wireless Access Points

• IP Cameras

ITS NOT “JUST A WIRE” ANYMORE

TODAYS TECHNOLOGIES IMPACT THE CABLE INFRASTRUCTURE:

• Gbe (Horizontal and Backbone)

• 10Gbe (Horizontal and Backbone)

• Power over Ethernet

• Voice Over I.P.

= ADDITIONAL PATHWAYS, SPACES AND RACK SPACE!!!

* The ENTIRE Cable Infrastructure Can Only Run As Fast As Its Weakest Link

Page 23: Network Technology Presentation   Bvh V01

SUMMARIZE

• TODAYS TECHNOLOGIES IMPACT THE ENTIRE CABLE INFRASTRUCTURE

• CAREFUL PLANNING IS REQUIRED

• FUTURE TECHNOLOGIES CAN RUN SEAMLESSLY OVER A STANDARS-BASED

CABLE INFRASTRUCTURE!
