GYFx®系列全干式光缆GYFY、GYFA、GYFS、GYFY53、GYFA53，是长飞光纤光缆（上海）有限公司在传统油膏填充式光缆基础上开发的一种新型光缆。采用特种阻水纱、阻水带等干式材料，取代了传统的纤膏、缆膏，完成了松套管和缆芯的阻水功能，是一种安全、高效的全干式阻水方式。
作为国内首次开发出此类全干式光缆的厂家，长飞（上海）公司已为该系列产品申请获得专利。
YOFC(SH) GYFx® series Totally Dry Cable, including GYFY, GYFA, GYFS, GYFY53, GYFA53, is a newly developed product on the basis of traditional gel filling optical fiber cable. Special dry materials such as water-blocking yarn and water-blocking tape are substitute for the gel filling to achieve the water-blocking purpose. Not only the cable core, but also the loose tube can completely prevent water from ingress. It is proved to be a reliable and effective method.
As the originally inventor of this Totally Dry Cable in
l 光缆接续前无需清除油膏和清洁光纤，提高安装效率，减少安装费用；
No need to remove messy gel and clean the fibers before splice, increase installation efficiency and save the expense.
l 光缆重量轻，方便敷设与维护，降低施工成本；
Light cable weight, be convenient for the installation and maintenance, and reduce construction cost.
l 由于没有使用油膏，避免造成环境污染和人体损害；
Gel free, avoid environment pollution and do no harm to human body.
l 干式阻水材料与光纤、光缆各组件具有更好的相容性；
Dry water-blocking materials are compatible with the optical fiber and each components of the cable.
l 非金属加强芯使光缆有效用于雷电频繁和存在干扰电流的场所;
All dielectric strength member ensure the cable be applied in the area of frequent thunder and current interference.
l 生产工艺和过程相对简单，可降低光缆的生产成本；
Simplify the production process, reduce the cable manufacture cost.
可广泛应用于核心网、接入网和光纤到户，敷设方式有管道、架空、直埋等。
Adopted to core network, access network and fiber to the home. Cable laying methods: duct, aerial and direct buried.
