Interfaces and external services can change. Follow the current on-screen controls, check dates and vendor documentation, and verify important results independently before acting on them.
Important: Do not rely on this result alone for purchasing, configuration, security, safety, compliance, contractual or fault-diagnosis decisions. Results can be incomplete, delayed, misleading or wrong. Verify important findings with the relevant provider, manufacturer documentation and an appropriate independent test or qualified professional.
Planning
Fibre Cable Guide guide
Compare fibre categories, connectors and common Ethernet optics for planning.
Open Fibre Cable GuideWhat you need
- Required speed, distance, fibre category and connector context
How to use it
- 1Identify the link speed and distance.
- 2Compare single-mode and multimode categories.
- 3Match the optic and connector at both ends.
- 4Verify the exact equipment datasheets.
Understanding the results
- Cable colour is only a clue; printed markings and specifications are stronger evidence.
Recommended next actions
- Confirm transceiver support, polarity, cleaning and loss budget before purchase.
Common problems
- Mixing incompatible optics, connectors or fibre types can cause loss or failure.
Privacy and security
- No network credentials are required.
Worked example
- Scenario
- Planning a 10 Gb link across a building
- Example input
- 10 Gb, 250 m, existing OM3
- How to read it
- The guide helps shortlist a compatible multimode optic, subject to both device datasheets.
Limitations
- Actual reach depends on optic specification and the complete optical loss budget.
Do not rely on one result for a production, security, safety, purchasing or contractual decision. Verify important findings independently.
