The GJYXCH self-supporting butterfly drop cable is designed for subscriber connections in Fiber to the Home (FTTH) networks and is also suitable for FTTO, FTTB, and other fiber access applications. It features a compact butterfly-shaped cable core, two parallel phosphated steel wire strength members, and an additional steel messenger wire for self-supporting aerial installation. The low-smoke zero-halogen (LSZH) flame-retardant outer sheath provides protection for indoor and subscriber access environments.

With its reinforced structure and integrated messenger wire, this cable offers improved tensile performance for overhead drop connections. Its compact profile and easy-stripping design simplify installation, fiber splicing, and maintenance in residential buildings and commercial premises.

Key Features

• Self-Supporting Structure: An integrated steel messenger wire provides additional tensile strength for aerial subscriber drop installations without requiring a separate support cable.
• Dual Steel Strength Members: Two parallel phosphated steel wires reinforce the cable core and improve resistance to tensile forces and external pressure.
• Bend-Insensitive Fiber Compatibility: Supports B6-series optical fibers to help maintain transmission performance in installations with tight bends and corners.
• Compact Butterfly Design: The flat cable profile facilitates routing through building access pathways and subscriber premises.
• Easy Stripping and Splicing: The central groove simplifies sheath removal, fiber access, fusion splicing, and field maintenance.
• LSZH Flame-Retardant Jacket: The low-smoke zero-halogen sheath supports indoor cabling requirements where reduced smoke and halogen emissions are important.
• Flexible Fiber Options: Supports up to four optical fibers for different subscriber connection requirements.
• Multiple Jacket Colors: Available in white or black to suit different installation environments.

Product Overview

The GJYXCH self-supporting butterfly drop cable provides a practical solution for the final connection between fiber distribution points and end-user premises. Its design combines optical transmission, mechanical reinforcement, and aerial support in a compact cable assembly.

The optical fiber is positioned at the center of the cable, with two parallel phosphated steel wires arranged on either side. These strength members reinforce the cable core and help protect the optical fiber against mechanical stress during installation and operation. An additional steel messenger wire provides load-bearing support for overhead installations requiring a defined span.

The LSZH flame-retardant outer jacket helps meet indoor cable safety requirements while protecting the cable structure during handling and routing. The butterfly-shaped profile and central groove also simplify cable stripping, fiber termination, and fusion splicing, improving installation efficiency for access network technicians.

The cable supports several single-mode fiber options, including B1.1, B1.3, B6a, and B6b. Conventional single-mode fibers are suitable for standard optical access links, while bend-insensitive fiber options help accommodate tight bends and space-constrained installation routes.

With its integrated messenger wire, reinforced metal structure, and compact dimensions, the GJYXCH cable is suitable for aerial subscriber drops and last-mile fiber access projects where additional tensile support is required.
