Issue 1.01

Both of the testing documents TSD-2000-4-2-1 (for LSPM) and TSD-2000-4-2-2 (for OTDR) provide guidance on the application of BS EN 61280-4-1 – which features requirements or recommendations for the use of reference grade terminations on the test cords. TSD-2000-4-2-3 results from work undertaken by FIA Project Team RGT on the specification, procurement and use of test cords – which is critical now that the pass/fail limits for many installed links have dropped to such low levels.
