The Reflex Photonics LLF and SLF optical FMC mezzanine cards may be used in applications including embedded VPX systems and industrial applications. They may also be used as evaluation platforms for the LightABLE™ LL and the SpaceABLE® SL optical transceiver modules.
The electrical interfaces are based on CML logic levels and support 10 Gbps data rates per link, for a total bandwidth of 100 Gbps full duplex (10-lane VITA 57.1) or 120 Gbps full duplex (12–lane VITA 57.4) and 240 Gbps half duplex (12–lane VITA 57.4) depending on the version.
The FMC cards are available for use in rugged applications using LightABLE optical transceivers (LLF models) or rugged applications in space using the SpaceABLE optical transceivers (SLF models). The cards are single-width conduction-cooled VITA 57.1 or VITA 57.4 cards. An optional MPO front panel bracket accessory is available for compatibility with air-cooled applications.
The LLF and SLF cards incorporate optical modules with preprogrammed parameters for configuration—only power and high-speed signaling is required. An I2C serial interface is provided to interrogate the module.
