Can you repair a cut fiber cable yourself?

No, an optical fiber core is as thin as a human hair and requires a professional fusion splicer to fuse the glass together with extreme precision. Mechanical quick-fix connectors cause unacceptable signal loss and will fail over time.

How quickly can you respond to repair a damaged fiber cable?

For urgent fiber outages, such as during property excavation or landscaping, we prioritize rapid troubleshooting and repair throughout Greater Stockholm to minimize downtime.

How do you locate an invisible fiber break?

We use advanced OTDR instruments (Optical Time Domain Reflectometer) that send light pulses through the cable to measure down to the exact meter where the break or attenuation is located, even inside buried conduit.

Do RUT or ROT tax deductions apply to fiber repair in houses and apartments?

Yes, repairing and installing fiber optic cables and data networks inside the home (both houses and apartments) qualify as IT services for a 50 percent RUT tax deduction on labor costs. For excavation and cable laying in the ground on your property lot, the 30 percent ROT tax deduction applies instead. We apply the deduction directly on your invoice.

Do you provide a measurement report after fusion splicing?

Yes, as an authorized electrical contractor equipped with in-house calibrated OTDR testers, we always perform optical attenuation testing and provide a written measurement protocol verifying optimal bandwidth.

Can you relocate or extend a fiber box or media converter indoors?

Yes, we regularly assist with professional cable extension, rerouting, and precision splicing when relocating fiber boxes during renovations or remodeling.

How We Repair Broken Fiber and Severed Cables

Fast Contact

Call us directly for emergency advice and booking. We usually respond the same day, including evenings and weekends.

Troubleshooting & OTDR Testing

Fusion Splicing & Verification

We splice the fiber optic cable with our fusion splicer, perform attenuation checks, and ensure your internet is fully functional before leaving.

Emergency Repair of Severed Fiber Optic Cables and Ground Excavation

Fiber cuts frequently occur without warning during garden landscaping, deck construction, drainage, or earthworks when an excavator or shovel damages the underground conduit. When a fiber line is severed, Smista Elinstallation provides rapid response across Greater Stockholm. We expose the damaged section, inspect the microducts, and fuse the microscopic glass fibers inside robust, watertight splice enclosures certified for direct underground burial. Once reburied with protective conduit, your high-speed internet link is fully restored.

Precision Fusion Splicing and OTDR Troubleshooting

Because fiber optics transmit data via light pulses through microscopic glass cores, twisted repairs or mechanical quick connectors cause unacceptable signal attenuation and fail over time. Our certified technicians utilize advanced fusion splicers with automatic core alignment that fuse fiber ends with an electric arc for near-zero attenuation (under 0.05 dB per splice). Using calibrated OTDR (Optical Time Domain Reflectometer) instruments, we pulse light through the strand to locate hidden faults down to the exact meter and certify the entire optical link before commissioning.

Building Networks, Cross-Connection, and Fiber for Businesses and Housing Cooperatives

For housing cooperatives (BRF), property managers, and commercial enterprises, we install, terminate, and upgrade complete property fiber backbones. Our services encompass termination and fusion splicing in optical distribution frames (ODF), patch panel cross-connections, and structured routing of fiber and Cat6 data cabling in server rooms and comms racks. We ensure maximum bandwidth, compliant labeling, and dependable redundancy for high-performance enterprise networks.

RUT and ROT Tax Deductions for Fiber and Data Networks

Private homeowners benefit from generous Swedish tax relief when hiring Smista Elinstallation for fiber and network projects. Indoor repairs, relocations, and installations of fiber cabling, media converters, and data networks qualify for a 50 percent RUT tax deduction on labor costs for IT services in both villas and apartments. For trenching, excavation, and conduit burial on your residential lot, the 30 percent ROT tax deduction applies instead. We apply the deduction directly on your invoice and handle all reporting to Skatteverket.
