The free connectors which terminate two and four pairs in field and laboratory conditions are included. This second edition cancels and replaces the first edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - measurement of the transmission performance of modular plug terminated link (MPTL) and direct attach cabling were added. - Additional requirements of test head designs of E2E link were introduced. The contents of the corrigendum 1 (2022-09) have been included in this copy.
