GJFJBV Flat Twin Duplex 2 Core Indoor Optical Cable

Description

This flat twin duplex indoor cable utilizes either 900μm or 600μm flame-retardant tight buffer fiber for optical

communication. The tight buffer fiber is reinforced with aramid yarn as strength member units, and this ass-

embly is extruded with a layer of PVC or LSZH material as the inner jacket. The cable is then finished with a

layer of flat PVC or LSZH jacket, providing a comprehensive outer sheath with low smoke, zero halogen, and

flame-retardant properties.

Application

1 Indoor Distribution: Tailored for indoor applications, this cable is designed to facilitate efficient communication
within buildings.
2 Pigtail Compatibility: Well-suited for use as a pigtail, seamlessly connecting with communication equipment to
ensure reliable performance.
3 Suitable for Communication Equipment: Specifically crafted to meet the requirements of communication equi-
pment, ensuring compatibility and effective service.
4 Convenient Installation: Engineered for easy installation, the cable can be conveniently set up, providing a
straightforward process for various communication applications.

Characteristic

1 Flat Twin Configuration: The cable is structured with two single fibers as the basic unit, arranged in a flat

twin configuration for practical use.

2 0.6 Tight Buffer with Kevlar Yarn: Each single fiber is equipped with a 0.6 tight buffer, reinforced with Kevlar

yarn for enhanced durability and protection.

3 Flexible or Independent Strength Member in Outer Sheath: The outer sheath of the cable features either

flexibility or an independent strength member, providing additional support and resilience.

4 Excellent Mechanical and Environmental Performance: Engineered for superior mechanical and environmental

performance, the cable is designed to withstand various conditions while maintaining reliable functionality.

Standards

* The GJFJV cable aligns with multiple standards such as YD/T1258.2-2003, ICEA-596, GR-409, IEC794, and

others. Additionally, it fulfills the criteria set by UL for OFNR (Optical Fiber Nonconductive Riser) approval.
