01
Design inputs
Specify both termination addresses, fibre count, connector type and intended optical system. Request fibre type, route length, attenuation, splice records and bidirectional OTDR traces. A fibre category such as G.652 is a starting point, not a complete optical design.
02
Delivery scope
Define demarcation at each optical distribution frame, local access and every intermediate handoff. Confirm rack space, power and site access for customer equipment, and responsibility for amplifiers or regeneration. Lease and long-term fibre-right arrangements require a segment-specific proposal.
03
Acceptance & operations
Agree measured loss at the working wavelengths, test methods, repair ownership, access procedures and change notification. Assess shared ducts and cable sections when requesting diversity. Unlit-fibre availability must be confirmed independently of a carrier's lit-service map.
