we describe a new design of high-speed data transmission
used in BESIII trigger system
with optical fibers that was based on the on-chip serial/deserial transmitter in FPGA.Multi-channels and real-time data transmission was studied and tested carefully.A high level of confidence bit error rate
better than 2.3 × 10-16
was obtained.Real-time data could be transmitted synchronously among multi-channels.The transmission was tested in cosmic-ray test of MDC of BESIII.It provides reliable data transfer and meet the requirements of BESIII.
