FAQ's - General

  • 1.01 - What are the UJ products?

    The Universal Joint (UJ) is a solution for connecting different types of submarine optical telecommunication cables, regardless of design or manufacture, using common construction equipment and standard piece-parts in the joint.

    Building on the UJ principles, the UQJ (Universal Quick Joint) has been developed to connect smaller diameter un-repeatered submarine cables taking account of the simpler cable construction and the requirement for a faster and simpler process.

    The UC (Universal Coupler) is a solution for coupling types of submarine optical telecommunication cables to submerged housing (repeater, equalizer, branching unit), regardless of design or manufacture, using common construction equipment and standard piece-parts in the joint.

    UJ, UQJ and UC products are therefore jointing piece parts or jointing tools produced and sold by each Consortium Member.

  • 1.02 - What is the UJC and who are the UJC?

    UJC is the short name of for the Universal Jointing Consortium made up of four members:

    - Alcatel-Lucent Submarine Networks (ASN)

    - Global Marine Systems Ltd (GMSL)

    - Kokusai Cable Ship Co Ltd (KCS)

    - SubCom, a TE Connectivity Limited Company (TE SubCom)

    The UJC members share a common aim to cooperate on the development and maintenance of a standardised cable jointing technology for underwater cables known as Universal Jointing (UJ), Universal Coupling (UC) and Universal Quick Joint (UQJ).

    The origin of universal jointing for fibre optic cables goes back to the late 1980s, when AT&T, BT (Marine) Ltd and Les Cables de Lyon, formed a consortium to supply an universal jointing and coupling solution for installation and maintenance purposes. The aim was to supply a standard jointing technology platform that offers common tools and piece parts for assembly of joints in different cable types. By the early 1990s, the four members listed above were actively involved in the development of the universal jointing technology. The first consortium agreement was signed in 2000 to develop and improve the universal jointing technologies. The members have recently renewed the agreement to continuing their commitment and collaboration in this field.

    Today, the majority of maintenance authorities for undersea telecommunications cables deploy UJ technology and standards on their cable systems worldwide.

  • 1.03 - What’s the difference between a UJ, a UC and a UQJ?

    The UJ (Universal Joint) and UC (Universal Coupling) are used in medium and long-haul submarine networks where repeaters or optical amplifiers are deployed.

    The UJ provides a connection between cables and the UC provides a connection between a cable and submerged plant optical housing such as a repeater or branching unit.

    The UQJ (Universal Quick Joint) is a cable-to-cable joint for use unpowered short-haul cable systems.

  • 1.06 - What is a UJ bulletin?

    A UJ bulletin is an official communication about any universal jointing topic, which has been agreed by all Consortium Members. All UJ bulletins can be found on our website: http://www.ujconsortium.com. Note official UJ Bulletin carry UJ consortium logo at the top of the bulletin. For ease of reference, bulletins are classified under 5 main categories:

    - Safety

    - New Product

    - Product Change

    - Information

    - Phase Out

  • 1.07 - Is there a system or procedure to keep good track of UJ kits and piece parts?

    Traceability of components is one of the fundamentals of the UJC product and as any effective QA system, is assured in the supply and implementation of the technology. For the supply of UJC products, each individual UJC member, as suppliers of the KITs, maintains an effective traceability system for material, manufacturing and inspection records, traceable from the KIT number and unique serial number including on the KIT box labelling. In addition each separate part included within the kit has traceability labelling which allow for the same records to be retrieved.  As such, users of the UJ technology can put in place as well a system that records the sealed KIT’s serial number or details of unkitted piece parts used, through their own QA organisation. Establishing the traceability system in inventory is kits owner’s responsibility. For any enquiry on a KIT’s traceability records the provider of the kit should be contacted in the first instance giving the KIT and serial number. Where the supplier is not known the coordinator should be contacted.

  • 1.08 - Does the UJC provide consultancy services?

    The UJC does not offer consultancy services but the individual consortium members may provide such service. Customers should contact directly individual consortium members for more information on such services.

  • 1.09 - Does the UJC provide guidelines on jointing activities management?

    UJC members provide the training and qualification of UJ/UC/UQJ qualified jointers.

    Guidance / recommendation on the size and degree of qualification of operational jointing teams as well as jointing work organization, e.g. equipment sparing or QA organization is outside the UJC remit.  These activities are the responsibility of the companies using or providing marine services.

  • 1.10 - Does UJC provide marine services?

    No. The UJC’s role is to collaborate on development of common jointing technology. Marine services are not part of the scope of the consortium.
