Before you specify fibre sensing
A practical working brief for infrastructure project teams. Use it before requesting proposals or agreeing a trial.
Use this worksheet before requesting proposals or agreeing a trial. Write what is known and mark what still needs evidence. It is a discussion aid, not an engineering specification or acceptance standard.
1. Define the decision
Asset or application:
Operating problem and consequence:
Decision required, owner and deadline:
2. Describe what useful information means
Event or condition to detect or measure:
Required location, timing and verification:
Who receives the information and what action follows:
3. Establish the starting point
Known fibre route, access and survey status:
Installation, power, communications and interface constraints:
Unverified assumptions and who will resolve them:
4. Compare the full scope
- Equipment, software and licence rights are described.
- Fibre, site work and access responsibilities are stated.
- Integration, commissioning and training are included or explicitly excluded.
- Recurring support costs and customer operating tasks are recorded.
- Unpriced dependencies remain visible as unknowns.
5. Agree the evidence
Representative target events and ordinary conditions:
Acceptance criteria, evidence record and decision authority:
Known limitations and treatment of incomplete results:
6. Choose the next action
Next step: clarify the brief / survey / compare proposals / trial / review evidence
Named owner and decision date:

How to choose a fibre sensing solution
Define the operating problem. Test the assumptions. Give suppliers a brief they can answer.
