MTS-4000 MPO OTDR: All-in-one integrated solution automating OTDR tests of MPO cables.

This OTDR is well suited for use in high-density fibre environments, multi-fibre MPO cables eliminate the expense of running individual patch cords for each service turn-up. Widely used in Data Centre interconnects, MPO cables are spreading into telecom access applications such as FTTH, FTTA or C-RAN. The use of an MPO switch is the best way to accurately and quickly characterize individual fibres of an MPO cables with an OTDR.

Intuitive Tier 2 Fibre Testing

Tier 2 testing with an OTDR is frequently performed in addition to basic, Tier 1 tests. Tier 2 is a complementary test to Tier 1 and fibre inspection and is recommended for proper documentation of the fibre infrastructure, and proof of work. The OTDR characterizes the different passive elements or events that have been installed and is the only effective test tool that locates breaks, damaged and/or dirty connectors, MPO excessive loss, bends and kinks, and fibre misrouting.
