Abstract: This presentation examines patch cord field performance problems relating to the 8-pin modular connector and cable assembly construction in general. Applicable standards such as ANSI/TIA-1096, IEC 60603-7 and IEC 60512-99-001 are reviewed. Compliance and verification issues and how they relate to patch cord performance are discussed. In addition, we will look at the darker side of patch cords in the marketplace; how false claims, inferior products and counterfeiting have the potential to slow down or disrupt network communications with potentially disastrous results. Possible solutions and safeguards are examined.
