Fiber Optics
Complete fiber optic solutions for businesses across Mississauga, Toronto, and the GTA — from backbone design and cable pulling to termination, testing, and certification.
Fiber optic cabling delivers the highest-speed, most reliable connectivity available for building and campus networks. AN Telecom Solutions provides complete fiber optic services for businesses across Mississauga, Toronto, and the GTA — from initial planning through installation, termination, and certification — for both single-mode and multi-mode applications.
Whether you need a backbone run between floors, a building-to-building link across a campus, or a fiber demarc extension from your ISP's point of entry, we handle the full scope of work and certify every strand before handoff.
Single-Mode vs Multi-Mode Fiber
The right fiber type depends on the distance, bandwidth, and application. Here's how they compare.
Single-Mode (OS1 / OS2)
Uses a smaller core (9 micron) and a single light path. Designed for long-distance runs — up to tens of kilometres. OS2 is the standard for most new outdoor and long-haul installations. Common for building-to-building, campus backbone, and ISP demarc connections.
Multi-Mode (OM3 / OM4)
Uses a larger core (50 micron) and multiple light paths. Designed for shorter distances — up to 300m (OM3) or 400m (OM4) at 10 Gbps. Common for in-building backbone runs between server rooms and telecommunications closets. OM4 supports 40/100 Gbps at shorter distances for data center use.
For most commercial buildings in the GTA, multi-mode OM3 or OM4 handles in-building backbone needs, while single-mode OS2 is used for anything that leaves the building or covers longer distances. We help you choose the right type based on your actual requirements — not just what's cheapest or most expensive.
Connector Types
We terminate and test all common fiber connector types used in commercial and data center environments.
LC Connectors
Small form-factor, push-pull latching. The most common connector in modern networking equipment and patch panels.
SC Connectors
Push-pull snap-in design. Common in legacy installations and some ISP demarc equipment.
MPO/MTP Connectors
Multi-fiber connectors (12 or 24 fibers) used in high-density data center and trunk cabling applications where space and speed matter.
ST Connectors
Bayonet-style twist-lock connector found in older installations and some industrial applications.
Our Fiber Optic Process
Every fiber project follows a structured approach to ensure reliable, certified results.
Planning and Design
Site survey, route planning, cable type selection (single-mode or multi-mode), connector specification, and capacity assessment.
Pulling and Installation
Fiber cable pulling through conduits, raceways, and riser shafts with proper bend-radius protection. We follow manufacturer pull-tension limits to prevent damage to the fibers during installation.
Termination and Splicing
Precision termination of fiber ends with LC, SC, or MPO connectors. Fusion splicing for permanent joins where connectors aren't practical — measured to under 0.1 dB loss per splice.
Testing and Certification
OTDR testing, light-source and power-meter testing, and full documentation of insertion loss for every strand. You receive a certified test report for your records.

Fiber optic cabling integrates directly with your structured copper cabling infrastructure. We frequently install fiber backbone runs that connect telecommunications rooms across floors, then transition to copper Cat6/Cat6A for horizontal distribution to workstations.
For server room and data center environments, we install high-density fiber patching in rack-mounted enclosures with proper strain relief and cable management.
Frequently Asked Questions
When do I need fiber instead of copper cabling?
Fiber is the better choice when you need to span distances over 100 metres (the limit for copper Ethernet), when you need bandwidth above 10 Gbps, or when you're connecting separate buildings. It's also required for ISP demarc extensions and backbone runs in larger buildings. For horizontal runs to individual desks, copper Cat6/Cat6A is usually more cost-effective.
What is OTDR testing?
OTDR (Optical Time-Domain Reflectometer) testing sends a light pulse down the fiber and measures reflections to identify the exact location and magnitude of any splices, connectors, bends, or breaks along the run. It's the definitive way to verify a fiber installation meets spec and to pinpoint problems in existing runs.
Should I choose single-mode or multi-mode?
For in-building backbone runs under 300 metres, multi-mode (OM3 or OM4) is typically the cost-effective choice and works with less expensive transceiver optics. For campus runs, building-to-building links, or anything over 300 metres, single-mode (OS2) is the standard. We recommend based on your specific distances and bandwidth requirements.
Can you extend a fiber run from my ISP?
Yes. ISP demarc extensions are one of our most common fiber projects. We extend the fiber from where your ISP terminates (usually the building entrance or basement) to your server room or telecommunications closet, including all splicing, patching, and testing.
