The JDSU ONT-600 Multiport Test Module (MTM) provides support for multiple protocols, Layers 1 to 3, and port density for 155 Mbps to 11.3 Gbps rates. The MTM supports multiport testing with four small form pluggable port banks consisting of an SFP for lower rates and an XFP for 10G rates. Each port bank supports one test, enabling up to four concurrent test sessions.
