The RSL connectors are the fastest FPGA connections available on SMT498.
As RSL are based on RocketIO transceiver blocks, the speed is limited by the speed
grade of FPGA installed:

Table 2 – RSL Speed VS FPGA Speed Grade

Based on the above, the 14 bi-directional links of SMT498 can provide a combined

bandwidth of up to 37.5Gbps.

Refer to the latest

SUNDANCE RSL specification

for technical information on how it

works.
