The purpose of this programme is to develop two C-band high power (30dBm and 35dBm) optical fibre amplifier engineering models for space laser communication. These amplifiers are ideal for use in the application of LEO to ground, intra and inter satellite links (LEO to GEO and GEO to GEO). To achieve this goal, the following objectives have been completed:
Module design, assembly, integration and test
The challenges within this programme include:
Achieving a design with a small footprint and low mass.
The optical fibre amplifier modules developed within this programme offer the following benefits:
Designed to ensure survival and operation of the module under harsh space environmental and launch conditions.
The modules developed feature:
Components have been tested and selected to minimise the effect of radiation induced attenuation.
The modules developed include the following:
D-Sub electrical interfaces
The project plan covers the following phases and milestones
Assembly integration and test, hardware acceptance review (HAR).
The project has successfully completed the Hardware Acceptance Review (HAR) in September 2018 after the assembly, integration and test of two optical fibre amplifier modules developed within the programme was completed. Images of the two modules are shown below.
