Quick answer
What is fiber optic cabling?
Fiber optic cabling carries data as light through glass strands instead of electricity through copper. It supports far longer distances and higher speeds than copper, isn't affected by electrical interference, and is the standard choice for building backbones, connections between buildings, and high-bandwidth links.
Los Angeles IT installs, splices, terminates, and tests fiber optic cabling for Los Angeles businesses from our Century City headquarters. Because we also configure the network equipment on each end, your fiber is installed with the switches and transceivers it needs to work. Projects are quoted after a site walk, and repairs are $95 per hour.

How It Works
How We Install Fiber Optic Cabling
Fiber work is precise. We document every strand so the next person knows exactly what's there.
STEP 01
Site walk
We map routes between rooms and buildings, check existing conduit and pathways, and confirm the speeds and equipment involved.
STEP 02
Design & quote
You get a fiber plan with fiber type, strand count, termination, and testing, plus a fixed quote.
STEP 03
Install & splice
We pull fiber through conduit and pathways, fusion-splice and terminate in enclosures, and label everything.
STEP 04
Test & connect
We test each strand, document results, and install and configure the switches and transceivers on each end.
Pricing
How Much Does Fiber Optic Installation Cost?
Fiber installation cost depends on distance, indoor vs. outdoor routing, existing conduit, strand count, fiber type, and the number of terminations. Every quote starts with a site walk, so the price reflects your building, not a guess.
Fiber repairs, troubleshooting, and re-termination are $95 per hour. Network equipment on each end can be included in the project or supported on our managed IT plans from $300/month.
What affects the price
- Distance and routing
- Existing conduit or new pathways
- Strand count and fiber type
- Splicing and terminations
- Indoor, outdoor, or buried runs

Fiber Types
Single-Mode or Multimode Fiber?
Multimode fiber (OM3/OM4) is common inside buildings for shorter backbone runs and uses lower-cost optics. Single-mode fiber (OS2) handles much longer distances and higher future speeds, and is the usual choice between buildings and for long campus runs.
We recommend based on your distances, existing equipment, and growth plans, and often install extra strands so future needs don't require a new pull.
Quick guide
- In-building backbone: multimode or single-mode
- Between buildings: single-mode
- Long campus runs: single-mode
- Spare strands for growth
Testing
Splicing, Termination, and Testing
A fiber link is only as good as its splices and connectors. We fusion-splice pigtails for low-loss terminations, mount them in rack enclosures, and clean and inspect every connector.
Each strand is tested with a light-loss meter and, where needed, an OTDR, which shows splice and connector loss along the run. You get documented results for every link.
What you receive
- Fusion-spliced terminations
- Labeled strands and enclosures
- Light-loss test results
- OTDR traces where required
Repair
Fiber Optic Repair and Troubleshooting
When a fiber link goes down, it's usually a damaged connector, a bad patch cable, a failed transceiver, or a physical break. We test from both ends to find the fault, clean or re-terminate connectors, replace optics, and splice breaks.
Because we also manage network infrastructure, we can tell whether the problem is the glass or the equipment.
Common fiber problems
- Dirty or damaged connectors
- Failed transceivers
- Breaks from construction
- Mismatched fiber and optics

FAQ
Fiber Optic Cabling: Frequently Asked Questions
How much does fiber optic installation cost?
It depends on distance, routing, conduit, strand count, fiber type, and terminations. We quote after a site walk. Repairs are $95 per hour.
When does a business need fiber instead of Ethernet cable?
Fiber is used when a run exceeds 100 meters, between buildings, for network backbones between closets, and where you need higher speeds or electrical isolation.
What's the difference between single-mode and multimode fiber?
Multimode is used for shorter in-building runs with lower-cost optics. Single-mode supports much longer distances and is standard between buildings.
Do you do fusion splicing?
Yes. We fusion-splice pigtails and repairs for low-loss connections and terminate in rack-mount enclosures.
Do you test fiber after installation?
Yes. Every strand is tested for light loss, with OTDR testing where required, and results are documented.
Can you run fiber between buildings?
Yes. We install indoor/outdoor and direct-burial fiber through conduit or aerial pathways between buildings.
Can you repair a broken fiber link?
Yes. We locate the fault, then clean, re-terminate, replace optics, or splice the break.
Do you install the switches and transceivers too?
Yes. As an IT company, we install and configure the network equipment on both ends of the fiber.
Is fiber faster than Cat6?
Fiber supports higher speeds over much longer distances. Inside a single room, Cat6A can also carry 10 Gbps up to 100 meters.
How long does fiber installation take?
It depends on distance and pathways. We give you a schedule with the quote after the site walk.
Can you upgrade our old multimode fiber?
Yes. We can test existing fiber to see what it supports, or install new single-mode or OM4 for higher speeds.
Which areas do you serve?
We install fiber across Los Angeles County, Orange County, the Inland Empire, and San Diego County.
