The history of XAGA series heat shrinkable closures & cable repair sleeves

The XAGA series heat-shrinkable closures, produced by CommScope (formerly under the Raychem brand), have a rich history in the telecommunications industry, tracing back to the innovations of heat-shrink technology developed in the mid-20th century.

Origins of Heat-Shrink Technology:

The development of heat-shrinkable materials can be attributed to Raychem Corporation, founded in 1957 by Paul Cook, a Stanford University chemical engineer. Raychem pioneered the use of radiation cross-linked polymers, which formed the basis for heat-shrinkable tubing. This technology found widespread application in electrical insulation and sealing, particularly for wires, cables, and components in harsh environments.

XAGA Series Introduction:

The XAGA series was introduced in the 1980s, specifically designed to address the needs of the growing telecommunications and fiber-optic industries. The series leveraged Raychem's expertise in heat-shrink technology, applying it to cable splicing and closure systems that needed protection against moisture, mechanical damage, and environmental exposure.

• XAGA 500/550: Initially, the XAGA 500 and 550 models were developed for copper telecommunications cables, offering high-quality environmental sealing and mechanical protection in both underground and aerial applications. These closures became popular for their ease of installation, durable sealing properties, and ability to extend the lifespan of spliced cables.

• XAGA 1000: As fiber-optic technology became more widespread, Raychem introduced the XAGA 1000, tailored specifically for fiber-optic cables. This model provided the same robust protection as the earlier models but was adapted to meet the higher performance demands of fiber-optic infrastructure.

Adoption and Growth:

During the 1990s and 2000s, the XAGA series became a standard in the telecommunications industry due to its ability to protect cable splices from environmental degradation, particularly in challenging conditions like moisture-rich environments, extreme temperatures, and mechanical stress.

Raychem was eventually acquired by Tyco International in 1999, and the XAGA series continued to evolve under Tyco Electronics. In 2010, Tyco Electronics became TE Connectivity, continuing to manufacture the XAGA series. Eventually, CommScope acquired TE Connectivity's Broadband Network Solutions (BNS) business in 2015, inheriting the XAGA product line, which remains widely used in fiber-optic and copper network installations worldwide.

XAGA’s Legacy:

The XAGA series' innovative use of heat-shrinkable materials to create reliable, long-term cable protection made it a foundational product in the development of modern telecommunications infrastructure. Its success comes from a combination of:

• Durability and sealing performance.
• Adaptability for both copper and fiber-optic cables.
• Ease of installation with heat-shrink technology, which reduces the need for extensive tools or preparation.

Today, the XAGA series remains a bench mark and trusted solution for telecommunications and utility companies looking to protect cable splices in various environments.
