LightSPACE 150G

LightSPACE radiation hardened optical transceivers

LightSPACE radiation hardened optical transceivers

Reflex Photonics’ LightSPACEradiation hardened transceivers are engineered to withstand radiation doses >100 krad. The LightSPACE embedded optical modules are rugged devices offering high bandwidth (greater than 150 Gbps) in a chip-size package. Furthermore, all our devices are “Space-qualified” as we carry out ECSS lot acceptance testing and component pre-screening for every batch targeted for this market. 

Specifications and features

  • Small: Less than 5 mm high.
  • Rugged: withstand radiation doses >100 krad and qualified per MIL-STD 883 shock and vibration.
  • Expected life: >20 years.
