abstract = {Accurate clock and time distribution is a key requirement
for self-triggered streaming data acquisition in the CBM
experiment. This distribution is handled by the Timing and
Fast Control (TFC) system by clock forwarding and
broadcasting the common time over latency-deterministic
optical links in a hierarchical FPGA network. The
point-to-point optical connections are served by the
latency-optimized GBT-FPGA core, which has been developed at
CERN. In the presented work, the performance of GBT-FPGA
links for time and clock distribution in a scaled TFC system
with multiple hops and endpoints has been investigated.},
