How do you observe your packet loss? Via SNMP? If you're using SNMP with
32 bit counters and a 5 minute poll interval, 110-115 Mbps is when you
should expect to see strange effects due to counter wraparound.

We use STM-1 links on several Juniper M7i routers, and have no problems.
We have observed traffic of more than 130 Mbps on quite a few occasions
(but this is when we *know* that the link in question needs an upgrade).
