Outer Mini Fiber Optic Armoured Cable GYFXTH Aerial Communications
G657A2
A 250 μm fiber is placed in a loose tube made of a high modulus
material. The loose tube is filled with a thixotropic waterproof
compound, and a glass yarn (or aramid) is added to extrude a LSZH
outer sheath. A fiber optic cable that is mainly used for
horizontal deployment of wireless base stations. At the same time,
it can be used for building cable in integrated wiring, which is
suitable for pipe wiring when it is introduced indoors.

FAQ:
1. Is there any oil in the optical cable?
According to the actual needs of customers, we do single core and
dual cores. Normally, there is no oil, but in special environments,
this kind of optical cable requires a loose tube with optical fiber
oil inside.
2. Is the 0.9 sheath inside the optical cable?
The FTTH solution we made for customers in the UK and South Africa
contains 0.9 sheath and fiber oil.
3.Is the optical cable lightning protection? Will it conduct
electricity?
This kind of optical cable is a pure non-metal optical cable
without metal inside, and can be used in aerial or antenna.
4.Does this optical cable have UV resistance?What is the service
life of the optical cable?
Our optical cables are black, all made of new materials, have
strong UV resistance, and can be used for more than 25 years.
5. What is the outer diameter of the optical cable?
The outer diameter of the optical cable can be produced at
2.0/2.6/2.8/3.0~5.0mm.Belongs to mini optical cable.
