GJJV-1B6A2 隐形光缆 – 0.9mm 尼龙紧套 G657A2

描述

GJJV-1B6A2 Invisible Optical Fiber Cable

GJJV-1B6A2 是一款0.9mm 尼龙紧套室内隐形光缆，专为隐蔽式光纤布线设计。采用 ITU-T G.657A2 弯曲不敏感单模光纤，即使绕过狭窄拐角和受限路径也能保证可靠的光学性能——是 FTTH 入户布线、多住户单元 (MDU) 安装和注重美观的表面贴装应用的理想选择。

Key Features

• 超薄外形：外径 0.9±0.1 mm，沿墙壁、踢脚线或天花板角落表面安装时几乎不可见
• 弯曲不敏感 G.657A2 光纤：宏弯损耗 ≤0.1 dB @1550nm（1圈10mm半径），可紧密布线而无信号衰减
• 耐用尼龙外护套：透明尼龙护套保护光纤，同时保持隐蔽外观
• 轻量化：约 0.9 kg/km，易于搬运和安装
• 宽工作温度：-10°C 至 +50°C 可靠运行

Applications

• FTTH 入户/楼内引入布线
• 多住户单元 (MDU) 光纤分配
• 沿墙壁、踢脚线、装饰线条表面安装
• 办公室和商业建筑光纤到桌面
• 酒店、医院和古建筑等要求最小视觉影响的应用
