forms of EMI

– Allows higher data rates and

longer distances than copper

Overview

3. Estimating Keys

HC Estimating Keys

• Specs located in Division 27

• Understand outlet configuration

– How many cables per WA outlet/drop location?

– Prints typically indicate via symbols and notes

• Remember distances

– 90M (295’) max

– Includes up/down (8’), service loops (1’ WA, 10’ TR)

– Max takeoff distance around 250’

– Include 10% overage on print distance for unknowns

• Identify if plenum cable needed! $$$

HC Estimating Keys

• Components

– 1 jack and 1 patch panel port per WA cable

– Patch panels typically 24- & 48-port configurations

– 1 RU (1.75”) horizontal manager per 24-port patch

panel

– 2 vertical cable managers per rack (1/2 rack or full rack

as needed)

• Be careful about Cat 6 requirements

– Most projects “min compliant” product

– 6E more expensive; make sure it is required

– 6A generally on high-end projects; make sure

HC Estimating Exercise

• Requirements

– 1 floor building; 10 WA with 2 Cat 6 min compliant cables

– TR in center of floor; existing rack already in place; no wire mgt

– Average cable run from prints is 150’

• Task

– Specify number of jacks, number and type of patch panels,

amount of cable, and horizontal and vertical wire mgt panels

– Faceplates: Assume 1 x 2-port, single gang for each WA location

HC Exercise Answers

• Components

– Jacks

• 2 jacks x 10 WA locations = 20 Cat 6 jacks

– Patch Panels

• 2 cables x 10 WA = 20 total cables

• 1 x 24-port Cat 6 patch panel

– Cable

• 150’ + 15’ (10%) + 16’ (up/dn) + 11’ (TR/WA svc) = 192’ avg

• 20 cables x 192’ avg cable = 3840’ (come in 1000’ boxes)

– Horizontal Wire Mgt

• 1 RU mgr / 24-port pp; 1 x 1 RU horizontal manager

– Vertical Wire Mgt

• 2 half rack verticals (may not require)

BB Estimating Keys

• Understand type of fiber required

– Some specs say “multimode”; several versions

– Use Accu-Tech team to specify correct version

• Fiber components

– 2 connectors / 2 adapter panel ports per fiber strand (1 each end)

– Adapter panels typically in 6- and 12-port versions

– Verify wall mount or rack mount fiber enclosures

– Example: 12-f from TR-ER, SC connectors, rack mount needs…

• 24 x fiber connectors; 2 x 12-pack SC adapter panels,

2 x 12-fiber or greater rack mount fiber enclosures

BB Estimating Exercise

• Requirements

– 12-strand, 50u MM fiber cable from ER to TR

– SC connectors

– Rack mount enclosure

– 200’ distance as shown on prints

• Task

– Specify number of connectors, number and type of patch panels,

number and type of adapter panels, and amount of cable

BB Exercise Answers

• Components

– Connectors

• 12 connectors x 2 ends = 24 x 50u SC fiber connectors

– Patch Panels

• 2 x rack mount fiber enclosures (12-fiber minimum)

– Adapter Panels

• 6-port: 2 panels per end; 4 x 6-port SC adapter panels

• 12-port: 1 panel per end; 2 x 12-port SC adapter panels

– Cable

• 200’ + 20’ (10% ovr) + 16’ (up/dn) + 20’ (TR svc) = 256’/cable

Testing

• Copper: What kind of testing required?

– Small jobs: Continuity only; larger: 568-C verified tester

– Accu-Tech can help you get the testers you need

• Fiber testing: What kind of testing?

– Power Meter Testing: tests the total loss (in dB) of the

cable plant (cable, connectors, splices)

– OTDR Testing (Optical Time Domain Reflectometer):

tests the total loss of the cable plan, but gives individual

values for loss at each connector and loss of cable

What are the three fiber optic connector types

commonly used today, and, which is the smallest?

3. Warranties and

Certifications

Specifications

• Generally, end users will develop a

specification for their data cabling,

including:

– Performance level required (Cat 5e/6, etc)

– Manufacturers accepted

• “Sole source”: one brand specified by name, no alternatives

• List of brands: two or more that are acceptable

• Performance only: no brands specified if meet performance

– Contractor qualifications

• Experience

• Industry Certs: RCDD (bicsi.org), BICSI certified techs, etc.

• Manufacturer Certs: Authorization by mfg to warrant installs

(more in final section, “Certifications and Warranties”)

Specification Strategy

• Use your relationship to influence spec

– Encourage the EU to write the spec in a way that favors

your experience, certifications, mfg relationships

– This puts you in a stronger position to win the bid

• Leveraging manufacturers with spec

– If you position a line…

• The mfg will register it with you

• This give you preferential pricing

– When a spec comes out listing mfgs…

• Be sure you are getting the “project pricing” available

• Be sure no other integrator is “protected”

(termination areas and cabling types)

of a 568-C compliant cabling system?

3. Warranties and

Certifications

Warranties

• Warranties

– Common industry practice for mfgs to offer extended

warranties on performance of cabling systems

– Term: Typically 25-year

– Requirements

• Use of required products

• Testing and documentation to 568-C standard

• “Certification” of installer

Certifications

• What is a certification?

– Marketing relationship between mfg and integrator

– Generally requires:

• Opening in geography (city) or market segment (schools)

• Commitment of annual purchase level

• Training of techs and designers (varies by mfg)

• What is a certification?

– Marketing relationship between mfg and integrator

– Generally requires:

• Opening in geography (city) or market segment (schools)

• Commitment of annual purchase level

• Training of techs and designers (varies by mfg)

• Why need certification?

– To compete on larger projects or at specific EUs must have it

– Can’t get one from everyone, so need to be strategic

• Check your customer’s specs: Who do they require?

• 1 brand name; 1 low-cost

1. The Importance of

Partnerships


Strategy


Commitment

The Right Partnership

Critical

• Accu-Tech: A Great Partner to Build On

– Carry every major line in the country

– 35 stocking locations from which to pull

– Know the landscape of this market

• We want to be your partner!

– Place you into projects

Partnerships


Strategy


Commitment

A Winning Strategy

Dedicate people to this endeavor

– Put someone in charge: “Everybody’s responsibility is

nobody’s responsibility”

– Focus salespeople, or at least, make cabling a focus:

Talk about it, incentivize it, measure it

– Have a group of dedicated (or, mostly dedicated) data

cabling technicians

Invest in training

– Sales and technical staff

– ATC, Bicsi.org, foa.org

A Winning Strategy

Start small

– Small wins leads to big wins

– Learn to quote, install, manage smaller, less-risky projects first

– Go after smaller projects with smaller clients first

– Shy away from quoting anything of size until you are ready


Partnerships


Strategy


Commitment

Critical Ingredient:

Commitment

• Difficult to break into a new market, to do it

profitably and long-term

– You will experience a learning curve, which will cost you

– You are going to make mistakes, and you likely will be tempted to

cut and run sometime in the first six months

• Therefore, up front commitment is critical

2 Key Commitments

1. Commitment to continue after failure

– Keep in mind the profit and increased control over accounts you

can have when (not if!) this division becomes a success

– Especially critical to keep in mind when you have a bad job, or

when one of your existing accounts gives the cabling to

someone else

2. Commitment to investing in this business

– $$$: Training, tools, incentives, marketing

– People: Focused staff, internal processes, accountability

If you do not invest in this business,

you will not succeed in it.
