Copper cable plant
Cat5e, Cat6 and Cat6A runs, home-run to a labeled patch panel.
NETWORKING & CABLING · CCB #249201 · MILWAUKIE, OR
The network is only as good as the cable plant under it.
Switches and Wi‑Fi get the credit. The copper and fiber underneath them get the blame when something drops. We pull, terminate and certify a cable plant built to carry what you plug into it today and what you plug into it in five years.
SECTION 01 / WHAT WE PULL
One cable plant, built to spec.
Copper for the desks and access points, fiber for the backbone, all of it home-run to a rack that makes sense to the next person who opens the door.
U02
Fiber backbone
OM4 and OS2 for building-to-building links and anywhere copper runs out of distance.
U03
Rack & patch
Dressed, labeled patch panels and grounded racks that a stranger could trace.
U04
Wi‑Fi cabling
PoE drops to access point locations planned around the building, not just the ceiling grid.
SECTION 02 / WHAT A RACK SHOULD LOOK LIKE
Dressed, grounded, labeled. Not a cable ball.
A rack somebody can trace with their eyes is a rack that gets fixed in minutes instead of hours. Cable management, grounding and labeling are not upsells — they are how the job is supposed to be done.
Licensed crew, twenty-two years in the trade, one invoice for the cable plant.
SECTION 03 / BUILDINGS THAT FIT
Any building with more than one closet.
- CommercialOffices, tenant improvement, multi-floor
- IndustrialWarehouse, plant, distribution
- RetailStorefront, multi-site rollouts
- EducationCampus, classroom, district
- HealthcareClinic, care facility, compliance-sensitive
SECTION 04 / READ THE LABEL
The spec sheet.
Published cabling standards, so the conversation starts with the same numbers. What your building needs depends on distance, device count and what you are plugging in at the far end — that is what the walkthrough is for.

SECTION 05 / WHY IT MATTERS
A network is only documented if somebody wrote it down.
A patch map that lives in one technician's head is a network that breaks the day he doesn't answer the phone. We hand over a labeled record before we leave — that is the actual deliverable, not the cable.
SECTION 06 / CERTIFY, DON'T EYEBALL
A cable that looks fine and a cable that tests fine are different claims.
Drops get a certification test as part of the process, alongside the visual check. That is the difference between a network you can trust under load and one that works fine until it doesn't.
Dressed, not dumped
Combed cable is not decoration. It's how you find the bad one.
SECTION 07 / DUE DILIGENCE
Before you hire anybody for cabling.
Four questions worth asking any bidder, including us.
- How is each drop tested and certified?Ask for a certification report, not just a handshake.
- Will you get a labeled port/patch map?Before the invoice, not after, and not held in someone's head.
- Is the category spec'd for your device count and PoE load?"Network cable" is not a category. Cat6 and Cat6A carry different loads over different distances.
- Who owns the switch configuration once cabling is done?Cabling and network configuration are usually two different scopes. Ask where the line is drawn.
SECTION 08 / THE RUN

SECTION 09 / THE OTHER TRADES
You own the network. We own the cable underneath it.
IT providers
You own the switches and the network. We get the copper and the fiber to where you need them, terminated, tested and labeled.
General contractors
We work to your schedule and alongside your trades. Off-hours and weekend pulls in occupied buildings are normal for us.
Property & facility managers
One licensed, bonded, insured contractor for the cabling across your buildings.
SECTION 10 / THE PART NOBODY SEES
Grounding is not optional. It's why the network doesn't hum.
A copper bus bar, bonded properly, is unglamorous and it is also the reason a rack full of switches doesn't develop ground loops six months later. We do it every time, not just when someone asks.
TELECOM ROOM
An IDF is a room, not a closet with a shelf.
A telecom room does specific jobs an ordinary closet does not: it holds temperature and humidity within a range the equipment tolerates day and night, not just during business hours; it runs off a dedicated circuit so a tripped breaker in a break room doesn't take the network with it; and it gives a technician clearance to stand in front of an open rack without turning sideways. A plywood backboard on one wall carries the ground bar and any wall-mounted gear. The door swings out, not in, so it never blocks the rack it's protecting. None of this shows up on a floor plan drawn before the network was scoped — it gets added, or worked around, after the fact.
- CircuitDedicated, separate from lighting and outlet loads.
- ClimateTemperature and humidity held to a range year-round, not just office hours.
- BackboardPlywood, for the ground bar and wall-mounted gear.
- Door swingOutward, clear of the rack it protects.
- SizingSized to the drop count it serves, not the space left over.
PATHWAY & SEPARATION
Data cable routed next to a ballast is a fault waiting on a schedule.
Low-voltage data cable and power conductors share a lot of the same ceiling space, and code sets rules for how close they get. Run copper cable parallel and close to a lighting ballast, a motor, or a transformer for any distance and it can pick up enough electrical noise to show up as errors on a live link — the cable still passes a continuity check, but the network drops packets under load. Where a data run has to cross power, it crosses at ninety degrees, not alongside it. Cable tray gets filled to a fraction of its capacity, not packed tight, so a cable can still be pulled or added later without damaging what's already resting on it. None of this is visible once the ceiling tile goes back up.
- SeparationMinimum distance held from parallel runs of power conductors and ballasts.
- CrossingAt ninety degrees, never run alongside power.
- Fill ratioConduit and tray filled to a fraction of capacity, not packed tight.
- SymptomInduced noise shows up as link errors, not a failed continuity test.
- TimingRouting decided before the ceiling tile goes back, not after.
TOPOLOGY & DISTANCE
Every drop is a star, home-run to one room, on purpose.
Structured cabling is built as a star: every outlet runs its own cable back to one telecom room, and no drop ever daisy-chains from one device to the next. That single rule is what makes a bad cable a one-outlet problem instead of a building-wide one. The star has a distance budget, too — a permanent link tops out at ninety meters, and the patch cords at each end eat into the same hundred-meter ceiling. That number is routed distance, not straight-line: a cable that climbs a wall, crosses a plenum and drops down a chase can burn through the budget on a run that looks short on a drawing. A telecom room on the wrong floor doesn't get a pass on the math — it just runs out of reach.
- TopologyStar only — no daisy-chaining between outlets.
- Link limit90-meter permanent link inside a 100-meter total channel.
- Patch cordsCount against the same budget at both ends.
- MeasurementRouted cable length, not straight-line distance.
- ReachFixed by geometry, not extended by adding equipment.
POWER BUDGET
A switch's power supply is a budget, and PoE devices spend it fast.
Every powered port has a class rating, but the number that actually matters is the switch's total PoE budget — the sum every port can draw from one power supply. Fill a switch with cameras, access points and badge readers and it's easy to spec a device count that the per-port rating allows but the chassis wattage does not, which is a gap you find at the worst time, not during the walkthrough. Load also has a physical side: a bundle of cables all carrying near-maximum PoE current heats up, and the more cables cinched together the more that heat has to dissipate somewhere, which is why guidance caps how many fully loaded cables belong in one bundle. Tallying device wattage before finalizing cable count is a planning step, not an afterthought.
- Budget checkPer-port class rating versus total switch chassis wattage.
- Load stackingCamera, access-point, and badge-reader loads stack against one power supply.
- HeatBundled cable heats up under sustained PoE draw.
- Bundle limitCable count per bundle scales with how heavily loaded it is.
- Planning stepDevice wattage tallied at design stage, before cable count is set.
CERTIFICATION PARAMETERS
A cable can pass a tone test and still fail every parameter that matters.
A tone-and-probe check confirms a cable is connected. Certification checks whether it performs. A certifier runs an autotest against published limits for wire map, length, insertion loss, near-end crosstalk (how tightly a pair's twist keeps it from bleeding noise into its neighbor), return loss, and propagation delay and skew between pairs (the timing difference between pairs once you push gigabit traffic across all four). Each parameter gets its own pass, fail, or marginal reading against the limit line for that cable category, not a single pass/fail for the whole link. A drop that's within spec on length and wire map can still fail on crosstalk if it was terminated with too much twist pulled out at the jack. That's the difference a report catches and a visual check does not.
- ParametersWire map, length, insertion loss, near-end crosstalk, return loss.
- TimingPropagation delay and skew between pairs.
- ScoringPass, fail, or marginal against its category's limit line.
- DistinctionA connected cable is not the same claim as a certified one.
- TerminationExcess twist removed at termination shows up as a crosstalk failure.
BACKBONE RISERS
Backbone cable crossing a fire-rated floor is a code problem before it's a network problem.
The backbone that ties an IDF on one floor back to the MDF has to get from one floor to the next, and that means crossing a fire-rated floor or wall assembly. Each penetration needs a firestop system rated to match that assembly, sized to the actual bundle of cable passing through it — not an oversized sleeve left open around the edges for whatever gets added later. That habit is exactly the problem: a riser sleeve opened up to make room for a future add and never resealed is a fire-rated floor that no longer performs to its rating, and it's how that rating quietly falls out of compliance years after the original build-out, long before anyone re-inspects it. Planning the riser pathway and its firestop at design stage, before the backbone is pulled, is what keeps that from happening.
- PathCrosses fire-rated floor and wall assemblies between IDF and MDF.
- Firestop ratingMatched to the assembly it penetrates.
- SizingSized to the actual cable bundle, not left oversized for later.
- Future addsMean resealing, not just reopening.
- PlanningRiser pathway and firestop planned before the backbone is pulled.
DEMARC TO MDF
The carrier's responsibility ends at a box on the wall.
Every building has a demarcation point — the spot where the carrier's incoming service physically ends and the building's own cabling begins, usually a small box near where the service enters. Past that box, extending the connection back to the actual MDF is the building's scope, not the carrier's, and it's a step that gets missed in a lease or a build-out because nobody assigned it to anyone. For a facility where downtime actually matters, that single entrance point is also a single point of failure: one cut line at the property boundary takes the whole building offline regardless of how redundant the network is inside the walls. Planning a second physical entrance path, on a different side of the building, is what makes that redundancy real instead of theoretical — and it has to be planned before the conduit under the parking lot gets poured.
- DemarcWhere the carrier's responsibility ends, not where the network starts.
- Scope gapExtending demarc to the MDF is building scope, easy to miss in a lease or build-out.
- RiskA single entrance path is a single point of failure regardless of internal redundancy.
- DiversityA second entrance path has to enter from a different side of the building.
- TimingEntrance conduit gets planned before site work closes it in.

SECTION 12 / BEFORE YOU CALL
Straight answers.
What's the difference between Cat6 and Cat6A for my office?
Cat6 runs 10 Gbps to about 55 meters; Cat6A holds 10 Gbps to the full 100 meter channel and handles higher PoE loads with less heat buildup in a bundle. Which one you need depends on distance and device count, which is what the walkthrough sets.
Do you test every drop?
Drops are terminated and tested as part of handover, and you get a labeled patch map.
Can you extend or fix cabling someone else installed?
Often, yes. We walk the site first and tell you what is reusable before quoting anything.
Do you run fiber too?
Yes, both OM4 multimode and OS2 single-mode for backbone runs and building-to-building links.
Are you licensed for this work?
We hold Oregon CCB #249201, Oregon electrical licence 4911LEA, CLE723 and Washington licence KNEPPJK854KK, with $2,000,000 in liability insurance and a $50,000 bond.
How do I get a quote?
Book a walkthrough. We count drops and closets, then you get a written scope and price you can compare against anyone else's.
