Start with the route and the work
| Option | Useful questions | Limit to resolve |
|---|---|---|
| Fiber | Is a protected route available? Which speed, optics and strand count fit the plan? | Pathway, cable rating, installation access and optical acceptance. Fiber does not supply PoE to the far building. |
| Dedicated wireless bridge | Is there a suitable radio path and mounting location at each end? | Obstructions, clearance around the radio path, interference, weather exposure and measured capacity. |
| Separate internet connections | Does each building need independent service or a secure connection between sites? | Provider availability, recurring cost, routing, remote access and support ownership. |
| Copper between buildings | Does the proposed link satisfy distance, environment and electrical design requirements? | Building-entry, bonding and surge concerns need a qualified design. A connector fitting is not approval. |
The workshop needs scanners and four cameras
Worked example
A nearby workshop, with trees between buildings
The office and workshop need shared business applications. Trees interrupt the direct radio path. Existing conduit might support a fiber route, but its condition and access are unknown.
Next step: inspect the proposed pathway and survey a viable radio path. Compare the installed cost, needed capacity, maintenance and failure consequences. Do not choose a bridge solely from the straight-line distance.
- Office networkRouting, access policy and an available uplink.
- Inter-building linkVerified fiber or a surveyed radio path.
- Workshop networkLocal power, switch, PoE and required Wi-Fi.
Specify what success looks like
“Test scanners along the working route while the four cameras stream at their planned settings. Verify allowed access to the office application and blocked access from guests. Record link performance, power dependencies and recovery after an agreed interruption.”
Add actual application targets, test duration and environmental conditions. A radio’s advertised link rate or an optic’s maximum reach is not an acceptance result.
Find the missing dependency
Your fiber path is ready, but the workshop has no suitable power for the switch and cameras. Can the fiber itself solve that?
Show the answer
No. Plan suitable local power, switching and device power at the workshop. Fiber carries the optical signal; it does not deliver PoE through the optical strand.

Read the answers and explanations
- Survey a viable path and compare a protected cable route.
Path conditions must support the design; distance alone is insufficient.
- Through a suitable local power and PoE arrangement.
An optical link does not remove the far building’s power requirements.
- The required tasks under planned demand, with access and recovery checks.
The test must reflect the actual work and conditions.
