国际环球接头联盟(UJC)-世界海缆权威的技术平台

国际环球接头联盟(UJC)是目前世界海缆行业的权威技术平台,成员包括法国的Alcatel-lucent、英国的GMSL、日本的KSC和美国的Tyco。世界海缆权威的技术平台是环球接头联盟(UJC),该联盟仅有四个成员,分别来自法国、英国、日本和美国。海底光缆要进入国际市场,必须通过该联盟的UJ认证,这就必须按照专用的技术规范,经过机械性能、电性能等在内的一系列严格测试。通过UJ认证后的海底光缆,一方面说明海缆已满足长距离传输、施工敷设要求,在性能上达到了国际水准,另一方面,说明各厂家生产的海缆能相互修复和链接,不会因采用不同厂家的海底光缆对新建及维修工程造成技术障碍。南京睿督公司咨询:025-8658 3475。

About UJ Consortium
 
Recent and Future Developments in Jointing Technology in the Undersea Telecommunications Industry
The introduction of the Universal Joint (UJ) made a huge impact on the undersea telecommunications industry when it was first introduced in 1990. As the demand for undersea cables continues to grow and cable maintenance becomes ever more complex, the role of the Universal Jointing Consortium (UJC) has never been more crucial to the industry.

The History of the Universal Joint
The philosophy of Universal Jointing for fibre optic cables was conceived in the late 1980's. In November 1990, the American Telephone and Telegraph Company, BT (Marine) Ltd., and Les Cables de Lyon, formed a consortium in contemplation of jointly entering into an agreement with the TAT9 fibre optic cable system purchasers to supply a Universal Joint and Universal Coupling (UJ/UC), for installation and maintenance. This new jointing approach (and technology) was aimed at allowing cable owners to avoid the need and expense of having to use a variety of manufacturer-specific cable jointing equipment.

The Universal Joint (UJ) is allowing manufacturers and cable owners alike, the freedom to install and purchase various underwater telecommunications cable types from different suppliers for the construction and maintenance of their networks. The standard UJ joint offers cable-specific components designed to fit together with a set of common piece parts using common tools for assembly.

The Universal Joint / Universal Coupling (UJ/UC) Consortium—which originally introduced the UJ/UC technology platform—has now grown into the Universal Jointing Consortium (UJC) with four members consisting of Alcatel Submarine Networks in France, Global Marine in the UK, Kokusai Cable Ship Co., Ltd. in Japan, and TE SubCom (US) Inc. in the USA. In addition to UJ/UC products, the UJC supports and maintains the Universal Quick Joint (UQJ) product platform. Consortium members each have specific responsibilities and work together to provide UJ, UC, and UQJ technology to worldwide cable operators, cable manufacturers, and maintenance contractors. It is testament to the effectiveness of the Consortium that these jointing technologies and standards have been adopted by the majority of optical undersea telecommunication cable maintenance authorities worldwide.

Generally, the UJ (provides a connection between cables) and UC (provides a connection between a cable and an optical housing, such as repeaters, branching units, etc.) are used in long-haul networks which are typically over 400 kilometres in length such as across Atlantic or Pacific routes. Networks of this length require the installation of repeaters or amplifiers at regular intervals along the cable to boost the optical signal as it travels down the fibre. In contrast, the UQJ was developed to meet the needs of the unpowered, non-repeatered, short-haul cable market.
