Velocity Cabling installs fiber optic cabling for commercial offices, data centres, warehouses, and multi-building campuses across Toronto and the Greater Toronto Area. We install single-mode OS2 fiber for long-distance backbone and campus interconnects, and multimode OM3, OM4, and OM5 fiber for high-speed data centre and IDF-to-MDF applications. Every fiber run is OTDR-tested and certified to TIA-568.3-D pass/fail limits. Full test documentation and as-built drawings are included with every project.
Fiber Optic Cabling — The Commercial Standard for Backbone Infrastructure
Fiber optic cable transmits data as pulses of light through glass or plastic strands, enabling speeds and distances that copper cabling cannot match. Fiber is immune to electromagnetic interference (EMI), does not degrade over distance the way copper does, and supports transmission speeds from 1Gbps to 400Gbps depending on fiber type and transceiver. In commercial structured cabling, fiber is the standard for backbone runs between MDF and IDF closets, building-to-building campus interconnects, data centre inter-rack connectivity, and ISP hand-off demarcation — all environments where distance, bandwidth, and interference immunity are critical.
Up to 400Gbps Capable
OM5 wideband multimode and OS2 single-mode fiber support 400 Gigabit Ethernet, providing infrastructure that remains viable well beyond current network requirements.
EMI Immune
Glass fiber carries light, not electricity. It cannot be affected by electromagnetic interference from motors, transformers, HVAC systems, or adjacent copper cabling — critical in industrial and mixed-use facilities.
Runs Up to 10km+
Single-mode OS2 fiber supports runs of 10 kilometres or more — enabling building-to-building campus interconnects and metro Ethernet connections that are impossible with copper structured cabling.
Future-Proof Infrastructure
Fiber optic cable has a functional lifespan of 25–30+ years. Upgrading from 10Gbps to 100Gbps or beyond typically requires only new transceivers — not cable replacement.
Fiber Types We Install — Single-Mode & Multimode
Choosing the right fiber type is a technical decision based on run distance, supported speeds, and future bandwidth requirements. We install all commercial fiber standards and advise on the right specification for your building and budget.
Single-mode 9µm core. Runs up to 10km+. Ideal for campus interconnects, building-to-building, and ISP demarcation. Supports 100G and beyond.
Wideband multimode 50µm. Supports 100G/400G at up to 150m using SWDM4 transceivers. Best for data centres targeting future 400GbE.
High-bandwidth multimode 50µm. Supports 100GbE up to 100m, 40GbE up to 150m. The current standard for data centre and IDF backbone applications.
Multimode 50µm. Supports 10GbE up to 300m, 40GbE up to 100m. Cost-effective for MDF-to-IDF backbone in smaller buildings.
Pre-terminated 12- or 24-strand MPO/MTP trunk cables for high-density data centre applications. Rapid deployment with no field termination required.
Duplex LC and SC connectors for standard fiber patch panels and switch connections. Field-terminated with fusion splicing or polished connectors.
Fiber Optic Applications — Where We Install
We install fiber optic cabling across a range of commercial environments. Common applications include:
MDF-to-IDF Backbone
Fiber backbone runs between main distribution frames and intermediate distribution frames on each floor. Typically OM4 or OS2 in a star topology from the main comms room.
Data Centre Interconnects
High-density MPO trunk cables and OM4/OM5 patch cords for Top-of-Rack and End-of-Row switching. Structured fiber management with labelled enclosures and splice trays.
Campus & Multi-Building
OS2 single-mode fiber between multiple buildings on a campus, industrial park, or university site. Direct buried, conduit, or aerial runs depending on site conditions.
IP Camera & CCTV Backbone
Fiber backbone feeding NVR locations and camera aggregation switches across large facilities. Eliminates distance limitations of copper for parking garages, warehouses, and perimeter coverage.
Wireless AP Uplinks
Fiber uplinks to wireless distribution switches for high-capacity Wi-Fi 6E deployments. Eliminates switch port contention and delivers dedicated bandwidth to each AP aggregation point.
ISP & WAN Demarcation
OS2 single-mode fiber hand-off from carrier demarcation to your MDF. Correct connector types, polish types (APC/UPC), and fiber management to meet ISP hand-off specifications.
Fiber Installation Methods — Fusion Splicing & Pre-Terminated
There are two primary methods for terminating fiber optic cables in commercial installations. We use both, depending on the requirements of each project.
Fusion Splicing
Arc fusion splicing joins individual fiber strands using heat to fuse the glass cores, producing insertion loss of <0.1dB per splice — the lowest achievable. We use fusion splicing for long backbone runs, any single-mode OS2 installation, outdoor conduit runs, and any project where maximum optical performance is required. Each splice is protected in a heat-shrink sleeve inside a splice tray, and all splices are OTDR-verified.
Pre-Terminated MPO/MTP Trunk Cables
Factory-manufactured MPO and MTP trunk cables offer consistent low-loss performance and rapid deployment for data centre and high-density environments. Pre-terminated 12-strand and 24-strand trunks plug directly into fibre enclosures, eliminating field termination time. We specify and source the correct polarity (Type A, B, or C), connector type, and fiber grade for your active equipment.
Field-Polished LC/SC Connectors
For patch panel terminations in smaller installations, we install field-polished LC and SC connectors using mechanical splice or epoxy-polish methods. Suitable for multimode OM3/OM4 in IDF closets and building backbone applications where full fusion splice equipment is not warranted. All connectors are inspected with a fiber microscope and insertion-loss tested before acceptance.
OTDR Testing & Fiber Certification — What We Test
Every fiber run we install is tested with an Optical Time Domain Reflectometer (OTDR) and power meter to verify end-to-end optical performance against TIA-568.3-D channel limits. OTDR testing is not optional on our projects — it is the documented proof that your fiber infrastructure will perform as specified. Testing parameters include:
Insertion loss measured end-to-end with a calibrated power source and meter. Verified against TIA-568.3-D maximum attenuation limits for each fiber type and length.
Return loss (optical reflectance) measured at each connector and splice. APC connectors achieve >60dB return loss; UPC >50dB. Documented on OTDR trace.
Full reflectometric trace showing each event (connector, splice, bend) along the fiber with position and loss data. Confirms no hidden damage, excessive bends, or failed splices.
Individual splice insertion loss verified to <0.1dB per fusion splice. Each splice position is located on the OTDR trace and included in the documentation package.
Exact cable length confirmed by OTDR. Verifies that horizontal runs do not exceed TIA-568.3-D channel limits and documents routing for as-built drawings.
Bidirectional OTDR testing performed on single-mode OS2 and all backbone runs. Eliminates masked events and produces averaged loss figures for accurate acceptance documentation.

Why Choose Velocity Cabling for Fiber Optic Installation
OTDR-certified documentation on every project
We do not accept fiber runs on visual inspection alone. Every strand is OTDR-tested and the traces are included in your handover documentation. You receive the proof — not just an assurance — that the fiber performs to specification.
Single-mode and multimode expertise
We install OS2 single-mode for campus and long-distance applications and OM3/OM4/OM5 multimode for data centre and backbone use cases. We advise on the correct fiber type for your specific distances, speeds, and future requirements — not just the cheapest option.
Commercial-only — occupied buildings & active sites
All of our fiber projects are in commercial or industrial environments. We work in occupied buildings, coordinate access with property management, and complete backbone work during off-hours where required to avoid network disruption.
Complete as-built documentation package
Floor plans with fiber routes, rack elevations, patch panel port schedules, TIA-606 label reports, and full OTDR test documentation. Your IT and facilities teams receive the full picture — not just a job completion notice.
Fiber and copper — integrated structured cabling
We install Cat6A horizontal cabling and fiber backbone in the same project. You get a single contractor, single documentation package, and a properly integrated structured cabling system — not two separate vendors who never coordinated on rack space or labeling.
