We install fiber optic cable for commercial buildings across Toronto and the GTA. Backbone between your MDF and every IDF, riser fiber up through the building, floor runs out to switches and equipment, and outside plant between buildings on the same site. Singlemode and multimode, indoor and outdoor, new build and live retrofit.
Every link is fusion spliced or factory terminated, tested against a calculated loss budget, labelled to the TIA administration standard and handed over with the results as a PDF. If a link degrades two years from now, you have the baseline that proves what changed.
What we install
Most fiber optic installation work in a commercial building falls into five jobs. A single project usually needs three or four of them.
MDF to IDF backbone
The backbone is the spine of the network. It carries every floor, every closet and every wireless access point back to the main distribution frame. We pull 6, 12, 24, 48 or 96 strand cable between the MDF and each IDF, splice it into rack mount enclosures, and leave you LC or MPO ports the switch team can patch into the same day.
Strand count is worth getting right once. Adding a second pull through an occupied riser costs more than the extra strands would have cost in the first place. We size the count for the switches you have and the ones you will buy next.
Riser fiber
Riser runs go floor to floor through a sleeved shaft or a dedicated telecom closet stack. In Ontario the cable has to carry the right flame rating for the space it passes through. FT4 for vertical riser, FT6 where the run crosses a plenum. We use rated cable, firestop every penetration we open, and keep the shaft photographed so the property manager has a record.
Floor runs and horizontal fiber
Fiber on the floor plate is for the runs copper cannot make. A camera at the far corner of a plant. A switch in a machine room 180 metres from the closet. A tenant suite two pours away from the riser. We run it in conduit, tray or J hook, terminate at a small wall mount enclosure and hand off to a media converter or an SFP port.
Fiber uplinks for switches
Uplinks are the fastest way to fix a slow branch of a network. Two strands and a pair of SFP or QSFP modules replace a copper uplink that was never going to get past a gigabit. We supply the patch cords in the right polarity, confirm the module matches the fiber type, and label both ends so nobody has to guess later.
Mismatched optics cause more uplink faults than bad fiber does. A 10GBASE-LR module on OM4 will link and then drop under load. We check the module, the fiber and the distance together.
Campus and building-to-building fiber
Between buildings on one property we install outdoor rated singlemode, direct buried in duct, in existing conduit, or aerial where a pole line already exists. Loose tube gel filled or dry water blocked cable, transitioned to indoor rated cable within the distance the code allows, grounded and bonded at both ends.
Singlemode or multimode, and how far each one goes
Multimode is cheaper to terminate and the optics cost less, so it wins inside a building. Singlemode costs more per port and goes as far as you will ever need, so it wins between buildings and on anything you expect to upgrade twice. Plenty of sites run both.

| Fiber | Core | 1 Gb | 10 Gb | 40 Gb | 100 Gb | Typical use |
|---|---|---|---|---|---|---|
| OM3 | 50 µm | 1000 m | 300 m | 100 m | 100 m | Existing in-building backbone |
| OM4 | 50 µm | 1100 m | 400 m | 150 m | 150 m | New in-building backbone, data rooms |
| OM5 | 50 µm | 1100 m | 400 m | 440 m | 150 m | Short reach 40 Gb over two strands |
| OS2 | 9 µm | 5 km | 10 km | 10 km | 10 km | Campus, outside plant, long backbone |
When copper runs out of room
Category cable stops at 100 metres. That is 90 metres of permanent link plus patch cords, and it holds no matter how good the cable is. Past that the link either fails outright or errors under load, which is worse because it looks like a software problem for weeks.
Fiber is the fix. It has no 100 metre wall, it does not pick up electrical noise, and it does not carry a ground fault from one building into another. The usual jobs we get called for:
- A shipping office or gatehouse well past 90 metres from the main closet.
- A camera or access control panel at the far end of a yard.
- Two buildings on one property that IT wants on one flat network.
- A production floor where drives and welders are corrupting a copper run.
- A mezzanine or new rack that needs its own switch instead of a long home run.
For a single device, a pair of media converters at each end turns two strands into an ordinary copper port. For anything more, a small switch in a wall mount rack is cleaner and gives you somewhere to grow.
Fiber optic installation in warehouses and plants
Warehouse work is its own trade. The distances are long, the ceilings are high, the racking is in the way and the building rarely stops running while you are in it.
What that means in practice:
- Route before cable. We walk the building first and find the path that survives a rack reconfiguration. Tray and conduit along a wall or a structural line, not the shortest diagonal across the ceiling.
- Armoured where it is exposed. Interlocked armour on anything a forklift mast, a scissor lift or a pallet can reach. Innerduct where it drops down a column.
- Height access planned, not improvised. Scissor lift or boom, with the aisle coordinated so shipping keeps moving. Most of this work happens on afternoons, nights or weekends.
- Electrical noise is not a factor. Fiber is glass. Variable frequency drives, welders, large motors and induction heaters do not touch it, which is exactly why copper keeps failing on those runs.
- Temperature and dust. Unconditioned space, loading docks and freezers need cable and enclosures rated for the range, and sealed enclosures where dust is heavy.
Fiber optic installation in offices
Office work is about the building rules more than the cable. Base building riser access, a certificate of insurance on file with the property manager, work outside business hours, protection on the finishes and a clean site at 6am.
The technical side is usually straightforward. Backbone from the MDF in the base building room to the IDF on each floor, a rack mount enclosure at both ends, LC patch panels, and copper distribution from there. On a tenant improvement we coordinate with the electrician and the drywall crew so the sleeves are in before the ceiling closes, which is the single thing that saves the most money on the job.
How the installation runs
- Site walk. We measure the real route, check closet space, power and grounding, and note what will need a lift or after-hours access.
- Design. Fiber type, strand count, route, enclosure and connector selection, and a written loss budget for each link.
- Pathway. Sleeves, conduit, tray, J hooks and firestop, coordinated with the other trades on site.
- Pull. Cable installed with tension and bend radius kept inside the manufacturer limits, with slack coiled at both ends for future re-termination.
- Termination. Fusion spliced pigtails or factory terminated assemblies into rack or wall mount enclosures.
- Test. Bi-directional loss on every strand, plus OTDR traces where specified.
- Label and close out. Ports, panels, enclosures and both cable ends labelled, with as-built drawings and the full test report.
Standards, testing and certification
An installation is finished when it is proven, not when it links. A switch will link across a bad splice and then throw errors under load six months later.
We build and test to the TIA structured cabling standards, and to the CSA flame ratings the Ontario Electrical Safety Code requires for the space the cable passes through.
Table 2
| Test | Equipment | What it measures | When it is needed |
|---|---|---|---|
| Tier 1 | Optical loss test set | Insertion loss, length and polarity on every strand, both directions, against a calculated budget | Every link, every job. This is the acceptance test. |
| Tier 2 | OTDR | A trace of every event on the strand: each splice, each connector, reflectance, and the location of any fault | Singlemode, long backbone, spliced links, outside plant, and anything under warranty |
Multimode loss testing is done with an encircled flux compliant launch, because the older mandrel wrap methods can put the same link a few tenths of a dB either side of pass. Reference cords get inspected and cleaned before every reference, and end faces get scoped, since dirty connectors cause more failures than bad splices.
Connectors, terminations and enclosures
LC is the default for anything new. Two fibers in the footprint of an old SC, and it is what every current switch and transceiver expects. SC and ST still show up on legacy panels and we match what is already there when it makes sense.
MPO and MTP is a 12 or 24 fiber connector in one housing, used for high strand count backbone and data room trunks. It cuts install time on a large pull and it keeps the enclosure tidy, but polarity has to be planned on paper before anything is ordered.
For termination we fusion splice factory pigtails in almost every case. The splice loss is lower and more consistent than field polished or mechanical connectors, and the end face quality is a known quantity. Mechanical terminations have their place on an emergency repair at 2am, not on a new backbone.
What drives the price
Two fiber jobs in the same building can differ by a factor of three. What moves the number:
- Route length and how hard the pathway is to get at. An open ceiling is quick. A hard lid with no access panels is not.
- Strand count and fiber type.
- Pathway work. New conduit, core drilling, sleeving and firestop are often more than the cable.
- Number of terminations. Every strand gets spliced and tested at both ends.
- Access. Lift work, after hours, union sites, escorted access and confined space all add hours.
- Testing level. Tier 1 is standard. Tier 2 adds time per strand.
We quote from drawings and a site walk, itemised, so you can see which line is driving the cost and decide what to change.
