Network tester

The ant-20E network tester, an expanded version of ant-20, checks Sonet and sdh hierarchies up to oc-48/stm-16 rates while also measuring jitter. A 2.5-Gbit/sec module for 1310 or 1550 nm, jitter modules for rates to 622 Mbits/sec, and jitter modules for 2.5 Gbit/sec are available. The unit enables access to electrical and optical interfaces from DS-1 to OC-48 and from E1 to stm-16.
