What is Universal Jointing?

  * Print
  * Email

Universal Jointing is a method of connecting all types of submarine
optical tele-communication cables with a common set of construction
equipment & methods.

kit details
The benefits of the Universal Joint (UJ) for the repair and
installation of subsea fibre optic cable systems are widely
acknowledged within the Telecommunication Industry. Since its first
installation in 1990 the technology has proven its reliability
in-service and provides an efficient and cost effective method of
connecting most types of submarine optical telecommunication cables,
using a common set of equipment and standardised piece parts.

Universal Joint Pedigree

For TAT-8 (commissioned 1988) the system suppliers, Cable de Lyon, AT
&T and STC, cooperated to integrate their own proprietary
Interconnection Devices ~ integrating three separate designs was
costly and troublesome.
As TAT-9 progressed a single joint concept was developed by AT&T (now
Subcom) and BT (now Global Marine) to simplify future maintenance ~
this became the UJ technology.
In 1990 Cable de Lyon (now ASN) joined the consortium.
In 1992, after the success of UJ in the Atlantic, KDD (now KCS)
joined the agreement as it was introduced into the Pacific.
In 1996 a new product, the Universal Quick Joint (UQJ) and agreement
was developed for the short-haul non-repeatered market.
In 2000 The predecessor organisations of SubCom, Kokusai Cable Ship
(KCS), Alcatel Submarine Networks (ASN) & Global Marine combined
agreements for the UJ and the UQJ to form a single agreement under
the

Universal Jointing Consortium (UJC)

recent cable systems where UJ has been used as the maintenance
solution include:
APCN2, Flag, SMW3&4, Unity, EASSy, EIG, WACS ....

UJC ruling principles

  * Advance the state of the submarine cable jointing arts, through
    sharing of the expertise for the mutual benefit of the submarine
    cable industry.
  * Optimize customer return on investment in the technology
  * Assure the uniform introduction of new and tested improvement to
    this technology in a cost-effective way.
  * Maintain common technical, manufacturing and engineering
