Talk to the installer
Discuss network cabling directly with TKWIT
TKWIT is a Sri Lankan systems integrator, not only a product seller: our own team surveys, designs, installs, tests and supports the system. Our Colombo-based team plans, installs, tests and supports projects across Sri Lanka, including Colombo 01–08 and Port City Colombo.
- Survey of cable routes, trunking, risers and rack position
- Copper data points and fibre backbone runs between floors or buildings
- Rack, patch panel and labelling work
- Testing of installed links, documentation and cable fault repair
Network points dead or a cable fault after renovation? Describe the location and we will advise.
Offices: Turnor Road, Colombo 08 and Iswari Road, Colombo 06. We reply to every enquiry as soon as we can.
Network cabling covers the practical work of getting reliable connectivity to desks, cameras, access points, printers, machines and other floors — including the untidy realities of an occupied building, existing trunking, shared risers and cable runs that were never documented. Cabling tests establish the condition of physical links; switching, VLANs, routing and provider connectivity need separate configuration and checks. The Orion City account documents dual-ISP UniFi networking and Wi-Fi, while the fibre and factory accounts describe distinct cabling work.
Plan the connected scope together: structured cabling layouts, patching and records; Wi-Fi and UniFi network planning; IP PABX voice connectivity; agreed network maintenance and support.

What's included
What does a network cabling job include?
Everything below is part of the scope we agree in writing before work starts.
Data point installation
New outlets at desks, counters, machines, cameras, access points and equipment positions, terminated and tested rather than simply pulled through.
Cable routes and containment
Trunking, conduit, tray and cable basket installed so runs are protected, separated from power where they should be, and not draped over ceilings.
Copper and fibre runs
Copper for floor and workspace distribution, fibre where distance, electrical noise or building separation calls for it — including between blocks and floors.
Rack, patch panel and switch termination
Cables brought back to patch panels in a tidy rack, patched into switches with a layout that can be traced by whoever comes next.
Upgrades and replacements
Replacing aged or damaged cabling, lifting an installation to a higher category where the equipment justifies it, and removing abandoned cable.
Troubleshooting
Tracing intermittent points, damaged runs, bad terminations and mislabelled patching — the faults that get blamed on the internet for months.
Labelling and records
Both ends labelled consistently, with a record of what runs where, so future changes take minutes rather than a morning of guessing.
Who it's for
Sites we do this work on
If your situation is not listed, ask anyway — we will tell you honestly whether it is work we do.
- Offices being fitted out, expanded or reorganised
- Businesses adding CCTV, access points or access control that need cabling first
- Factories and industrial units with long runs and harsh conditions
- Warehouses connecting offices, gates and stores across a site
- Retail and hospitality with counters, kitchens and back-of-house points
- Anyone inheriting an undocumented cabling mess from a previous contractor
Planning & design
What we work out before quoting
These are the decisions that determine whether the finished system is useful or merely installed.
- Count points, then add for change
- Desks move and equipment gets added. Providing a sensible margin of extra points during installation costs far less than returning for one outlet.
- When should a business use copper or fibre?
- Copper runs have practical length limits. Long site runs, links between buildings and electrically noisy routes point to fibre.
- Where does the rack live?
- Rack position drives every cable length on site. It needs ventilation, power, physical security and enough room to work in.
- Power over Ethernet loads
- Cameras, access points and phones drawn from switch power change switch and cable choices, so PoE is planned rather than discovered.
- Working in an occupied building
- Routes, working hours and dust control are agreed in advance so cabling work does not stop your operation.
- Cabling and Wi-Fi go together
- Wireless coverage depends on where cabling can reach. Planning both at once avoids access points landing in the wrong places.
How it works
Our implementation process
The same order every time, so you always know what stage the project is at.
- 01
Site survey
Point count, routes, rack position, existing containment and constraints.
- 02
Design and quotation
A written scope: point schedule, media, containment and rack arrangement.
- 03
Containment first
Trunking, conduit and tray installed before cable is pulled.
- 04
Cable installation
Runs pulled, dressed and terminated at both ends.
- 05
Testing
Every point tested and any failure corrected before handover.
- 06
Labelling and handover
Consistent labelling and a record of the installation.

Afterwards
Maintenance and support
Installation is the start of the relationship, not the end of it.
- Adding points as the office or site changes
- Cable fault finding and repair
- Rack tidy-ups and re-patching
- Upgrades when equipment outgrows the existing cabling
- Ongoing support alongside network and CCTV maintenance
Questions
Frequently asked
- What is the difference between network cabling and structured cabling?
- Network cabling is the practical work of installing and repairing data runs and points. Structured cabling is the designed, documented system behind it — a planned layout with defined distribution, patching and records. Small jobs need the first; whole floors and buildings benefit from the second.
- Does dual-ISP failover fix a damaged cable or guarantee uninterrupted sessions?
- No. WAN failover changes which provider connection the network uses; it does not repair a damaged local cable, failed switch or access point. Failover should be configured and tested for the agreed design, and session continuity should not be assumed. SLT and Dialog supply their circuits; TKWIT integrates the customer-side network.
- What information helps scope network fault finding?
- Describe which devices and outlets are affected, whether wired and Wi-Fi users see the same issue, when it occurs, and any recent layout or equipment changes. Existing outlet labels, rack records and available test results help distinguish physical-link faults from switching, routing or provider issues. Share sensitive configuration only through the agreed private support channel.
- Can you add cabling without disrupting our work?
- Usually yes. We agree routes and working times in advance, and much of the containment and pulling work can be done around your operation.
- Do you test what you install?
- Yes. Every point is tested and corrected before handover, and the installation is labelled so faults can be located later.
- Our network keeps dropping. Is that the cabling?
- Sometimes. Bad terminations, damaged runs and over-length cables produce exactly the intermittent behaviour usually blamed on the internet connection. We test to establish where the fault actually is.
- Which areas do you cover?
- We are based in Colombo and take cabling work throughout Sri Lanka, including Colombo and the surrounding districts. Tell us where the site is so we can plan the survey and quotation.

What people usually ask about alongside this
Structured Cabling
Structured cabling is the designed version of data cabling: one planned system serving the whole building, documented so anyone can work on it afterwards. We design and install it for offices, hotels and industrial buildings in Colombo and across Sri Lanka.
See Structured CablingWi-Fi Installation
We plan and install Wi-Fi for offices, hotels, warehouses and factories in Colombo and across Sri Lanka, so coverage holds up where people actually work — including the warehouse aisle, the far meeting room and the floor where everyone connects at once.
See Wi-Fi InstallationIP PABX & Phone Systems
We design, install and support IP PABX phone systems — extensions, menus, call routing and recording — running over the network you already have.

FAQ
Network Cabling: more questions answered
Can TKWIT design a complete business network?
Yes. TKWIT can design the switching, routing, firewall, Wi-Fi, VLAN, structured cabling and connectivity architecture required for offices, commercial buildings and distributed business environments.
What causes slow business networks even when the internet connection is fast?
Poor switching design, network loops, overloaded Wi-Fi, incorrect VLAN configuration, ageing equipment, cabling problems and local congestion can all affect performance independently of the internet connection.
Can you redesign an existing network without causing major downtime?
Yes. A migration can normally be planned in stages with configuration, testing and cutover windows designed around business operations.
