VMIC 332-999995-000 D RPTS Repeat Module

Module Feature

332-999995-000 D is a single-slot 6U VMEbus RPTS signal repeat module developed by VMIC,specially designed for VMIC fiber reflective memory ring network. It regenerates and reshapes serial fiber differential signals,restoring signal amplitude and timing integrity to extend the effective transmission distance of the reflective memory fiber ring. The module is fully interoperable with VMIC 5530M,VMIVME-5565,VMIPCI-5565 and other 5565 family reflective memory nodes. VME bus interface supports A16/A24 addressing and D08/D16/D32 data transfer,operates as VME slave for configuration and status readback. Dual fiber ports implement ring in and ring out connection;signal path uses hardware hardwired regeneration without software latency. Built-in BIT diagnostic continuously monitors optical receive power,signal lock status and power supply health;fault condition will latch alarm flag and drive front panel LED indicator. Rugged Eurocard PCB with conformal coating,shock and vibration screened for power plant cabinet environment,widely used in gas/steam turbine distributed control,hardware-in-loop real-time simulation,aerospace test and long-distance multi-node reflective memory VME chassis.

Working principle

In reflective memory fiber ring topology,the incoming serial optical signal is converted to electrical signal,clock and data are recovered,signal waveform is reshaped and re-amplified,then converted back to optical signal and forwarded to next ring node. This hardware regeneration eliminates signal attenuation and jitter accumulated over long fiber cable. VME interface only handles configuration and fault status reading;the main signal repeater path runs transparently independent of VME bus activity. BIT circuit monitors optical receiver power level and signal synchronization state to judge fiber link health.
