Spectrum
Keep your transponders and delegate the optical line system.
Spectrum allocates spectrum for compatible customer equipment over Colt’s line system. Between managed Wave and dark fibre, review compatibility and operations.
This is a specialised option: optical compatibility, engineering and operations must be assessed end to end.
Let’s talk
How it works
Scale your transmission without deploying the entire optical line system.
Customer transponder A
Colt line systemCustomer transponder BA boundary within the optical layer
The customer supplies and operates compatible transponders; Colt supplies the managed line system and agreed spectrum. The design defines signal injection and reception.
Validate channel width, modulation and signal compatibility with the route. Customer optical technology cannot be assumed to work over any line segment.
Customer transponder AColt line systemCustomer transponder BPerformance depends on optical margin
Modulation and transmission rate must fit the available margin. Review errors, signal quality and configuration with both operations teams.
A transponder change may require line-system revalidation. Technology flexibility is not permission to change it without coordination.

Distinguish transponder, line-system and physical-route failures. The procedure defines who diagnoses each side and what evidence they exchange.
An alternative route needs planned spectrum, compatibility and equipment. Test recovery and maintenance before carrying critical loads.
Illustrative case: from situation to decision
- Situation
- The company operates transponders but does not want to deploy the entire line system.
- Option
- Compare Spectrum, Wave and dark fibre by the optical responsibilities the team wants to own.
- Check
- Validate transponders, optical reach, allocated spectrum and responsibility for degradation.
Spectrum is neither dark fibre nor Ethernet; transponders and the line system have different owners.
Decisions for your project
- Optical compatibility
- Transponders, modulation, assigned spectrum and signal budget.
- Shared operations
- Alarms, demarcation, changes and coordination between teams.
- Route and evolution
- Diversity, maintenance and revalidation of future upgrades.
From design to operation
Joint technology and route validation, signal testing and agreement on a shared operating procedure.
