What we do
Fiber splicing, testing,
and emergency repair
Four services, one specialty. We splice and test fiber for internet service providers and utility contractors, and we answer the phone when a line gets cut.
24/7 Emergency Fiber Repair
Fiber cut? We roll now.
A cut fiber line is an outage that bills by the minute, and every hour it stays down is customers on the phone and penalties on the contract. Call us at any hour and we mobilize a splicer and a stocked trailer immediately, locate the fault, restore the strands, and hand you the test results.
- A splicer answers the phone, so the first conversation is technical rather than a ticket number
- Fully stocked splice trailer, so the repair does not stall waiting on closures or hardware
- OTDR fault location on arrival, because the visible cut is not always the only damage
- Every restored strand tested and documented, so you can close the ticket on evidence

Who we serve
We work for the people who build and run the network
Miller Optical is a subcontractor by design. Our clients are the providers and contractors who need splicing done to a standard they can hand to an owner.
Internet service providers
You have more fiber to terminate than splicers to terminate it, and the demand is lumpy. We add senior splicing capacity for the length of a build so you can meet the spike without carrying the payroll through the quiet stretch.
Utility contractors
You place cable extremely well and would rather not staff the specialty at the end of it. We work behind your crews on the splice and test scope, and we answer the phone at 2am when a bore finds a line the locate missed.
Municipalities and campuses
You own fiber that nobody has records for, and the first real problem is that the as-builts are wrong. We test and trace the fiber to establish what you actually have, document it, and fix what is broken, with the same crew doing both.
Project scale
We have worked the builds you are bidding
Splicing capacity is not measured in headcount. It is measured in whether the crew has done work at your scale before, whether they finish segments while the build is still moving, and whether the documentation is good enough that acceptance is a formality rather than an argument.
Miller Optical has run the splice and test scope on citywide fiber builds alongside our sister company Miller Utilities, which means we have seen these projects from the placement side as well as the splice side. That is a different kind of experience than repair work alone, and it is the reason we can tell you honestly at the bid stage what a schedule will actually take.
- Splice and test scope on multi-phase citywide fiber builds, not just single-segment repairs
- Shared project history with Miller Utilities, so we have worked the same builds from both ends
- Documentation produced as segments complete, which is what keeps a large build's closeout from stacking up
- Crews mobilize as a self-contained truck-and-trailer unit, so a remote phase does not need staging from you
Where we work
Based in Hastings, working the Upper Midwest
Miller Optical is based in Hastings, Minnesota, and our routine footprint covers Minnesota, North Dakota, South Dakota, Iowa, and Wisconsin. Fiber runs between towns rather than inside them, so we work corridors and builds rather than service territories.
Our crews travel as a self-contained unit, a truck and a splice trailer, so we mobilize nationally for the right project.

Beyond the region
Our crews carry everything they need with them: a truck, a splice trailer with fusion splicers and an OTDR on board, and the closures and hardware to finish the job. That is why distance is a scheduling conversation rather than a hard boundary. If your project sits outside the Upper Midwest, call and we will tell you honestly whether we can get there in a useful timeframe.
FAQ
Questions we get asked most
Don't see your question? Call us any time at (651) 273-3065 and we'll walk you through it.
Yes. Emergency splice repair is our featured capability and the line is answered around the clock, including nights, weekends, and holidays. If a fiber line has been cut, call (651) 273-3065 and we mobilize a splicer with a fully stocked splice trailer immediately. The person who answers splices fiber for a living, so the first conversation is technical rather than administrative.
Call us, then stop work at the dig site and leave the cable untouched. Do not pull the ends, cut them back, or tape them together, because every foot of preserved slack keeps the repair to a single splice point. Have the location, the approximate strand count, and the cable owner ready so we can load the right closures and hardware before we leave.
It depends on where our crew is when you call and where the damage is, so rather than quote a blanket response time we cannot honor, we give you a realistic mobilization window on the phone and update it if it changes. What we commit to is mobilizing immediately. Our crews travel as a self-contained truck-and-trailer unit, which is what lets us cover long distances without waiting on staging.
We are a fiber optic services contractor. That means fusion splicing for inside plant and outside plant, OTDR testing and loss certification, tracing and fault location, splice support alongside active builds, and 24/7 emergency repair when a line gets cut. We do not place cable and we do not do low-voltage or structured cabling, because staying narrow is what keeps the splicing standard high.
Our routine footprint is the Upper Midwest: Minnesota, North Dakota, South Dakota, Iowa, and Wisconsin. We are based in Hastings, Minnesota. Because our crews travel as a self-contained truck-and-trailer unit, we also mobilize nationally for the right project, so it is worth calling even if you are outside the region and we will tell you honestly whether we can help.
Yes, and that is most of our work. Internet service providers use us for contract splicing capacity when a build outruns their own splicers, and utility contractors use us for the splice and test scope behind their placement crews. We follow your standards, your labeling conventions, and your documentation format, and we do not bid placement work, so there is no conflict in bringing us onto a project you are already running.
Miller Optical has been splicing fiber since 2015, and we staff senior-level splicers on every job. There is no junior crew to send when the schedule gets tight, because we do not have one. Splicing is the only thing this company does, so the same experienced people show up on your project every time.
Yes, every splice is verified with an OTDR before the case is sealed, and the results come back to you as written documentation. We treat verification as part of splicing rather than an add-on, because a splice that passes visually but fails at loss budget is a truck roll you end up paying for twice.
Yes. Miller Optical is the fiber services division, and each company in the group runs its own specialty rather than sharing a general labor pool. We handle fiber splicing, testing, tracing, and emergency repair, while utility-scale construction such as directional boring, plowing, and cable blowing sits with Miller Utilities. If a project needs both, we can get you to the right crew rather than stretching ours to fit.
