The GT 380 Mobile Cable Drum is a high‑quality, portable cable reel designed for reliable deployment and retrieval of fiber optic and other low‑diameter cables in demanding environments. With an outer width of 380 mm, height of 491 mm, and depth of 291 mm, this compact drum offers an optimal balance between storage capacity and portability. The empty weight is approximately 3.9 kg, and even when loaded with about 240 m of 6 mm cable the total weight remains around 11.9 kg, making it easy to transport and handle by a single operator in the field.

Engineered for robust use, the GT 380 is made from durable plastic selected for impact resistance and long service life in harsh outdoor conditions. It is suitable for professional applications such as broadcast and events, industrial sites, temporary networks, data centers, mobile communication units, and emergency response scenarios. The rugged construction helps protect the cable from mechanical stress during transport and deployment, while also supporting neat, tangle‑free winding that reduces the risk of kinks and micro‑bending losses in sensitive fiber optic lines.

Despite its compact size, the GT 380 offers impressive cable capacity tailored to common fiber diameters. It can hold up to approximately 340 m of 5 mm cable, 240 m of 6 mm cable, 180 m of 7 mm cable, or 100 m of 9.2 mm cable. This capacity range makes it suitable for a wide spectrum of temporary and semi‑permanent connections, from shorter tactical links in event technology to longer runs in campus or industrial networking. The design supports smooth payout and rewind, improving workflow efficiency and helping crews work faster and more safely on‑site.

The GT 380 is optimized for modern fiber optic connectivity. It can be equipped with widely used fiber systems such as U‑DQ(ZN)11Y cables with diameters between 6.5 mm and 7.7 mm in 12‑ or 24‑fiber configurations, as well as A‑V(ZN)11Y(ZN)11Y cables of approximately 6.0 mm with 2 or 4 fibers. This makes the drum well suited for both high‑density backbone links and lower‑fiber‑count tactical lines. When integrated as part of a pre‑assembled system, it enables rapid deployment of plug‑and‑play fiber networks in environments where time and reliability are critical.

To support a broad range of field interfaces, the GT 380 can be configured with numerous connector types. These include Eurolens (HMA) expanded beam solutions from Amphenol Precision Optics for dirt‑resistant, harsh‑environment connections, high‑density MTP® connectors compatible with US Conec technology, and standard LC, SC, and E‑2000® (LSH) connectors for straightforward integration into existing fiber infrastructures. FO2 and FO4 circular fiber connectors, as used in many broadcast and military‑grade applications, are supported via Fischer 3K.93C and LEMO series interfaces. This broad connector compatibility allows the GT 380 to act as a flexible platform across different projects and industries.

For extended functionality in the field, the GT 380 can be enhanced with an optional internal patch panel. This panel is available with up to 12 SC simplex adapters or 12 LC duplex adapters, providing a convenient interface point for distributing signals, organizing multiple channels, or connecting to various devices and extension lines. Combining the internal patch panel with pre‑terminated cables and harsh‑environment connectors turns the GT 380 into a compact, mobile fiber distribution hub that simplifies temporary network design and reduces setup errors.

In addition to the base configuration, several practical options are available to adapt the GT 380 to specific use cases. A protection and cable laying tube can be supplied as an undetachable component to guide and protect the outgoing cable, improving bend control and strain relief. An auxiliary coil supports the management of shorter patch leads or service cables directly on the drum. The reel can also be specified with harsh‑environment connectors and delivered as part of a complete cabling solution that includes compatible junction boxes. For installations that require stacking multiple reels for transport or storage, a related stackable version (SK 380) is available, ensuring easy integration into larger fleets of mobile cable drums.

Overall, the GT 380 Mobile Cable Drum is a compact and robust cable management solution tailored to the practical requirements of professional fiber optic users. Its combination of durable construction, generous capacity for various cable diameters, extensive connector support, and configurable options such as internal patch panels and auxiliary coils provides a versatile platform for reliable field connectivity.
