This disclosure relates to fiber optic connector keying arrangements which prevent the unintended mixing of traffic when a plurality of similar fiber optic cables are to be interconnected with electronic equipment handling traffic of various types and classifications. The connector assembly at each end of a fiber optic cable comprises a hermaphrodite connector end plug (i.e., a keying insert) that has an end face configuration which is unique to that particular cable. The equipment (bulkhead) connector assembly to be connected to a given cable also includes a keying insert end plug which is identical to that of the cable. Thus, a given cable connector can be connected or coupled to, and only to, a similarly configured, bulkhead, connector assembly. Each cable comprises at each end a unique, keying insert, end plug and, therefore, each cable can be connected to only one similarly configured, bulkhead connector; and, undesirable connections, and consequent traffic mixing, are thereby precluded. Each cable and bulkhead connector assembly has a cover with a unique insert that exactly matches and precisely mates with its intended connector assembly.
