About optical fiber cable filler

is the main protective layer of the optical fiber, which can prevent the tidal erosion in the air and relieve the impact of external mechanical forces such as vibration, impact, and bending of the optical fiber, and is an important material that affects the service life of the optical fiber. The fiber compound allows the optical fiber to remain in a state of free low stress in the loose tube at all times, thereby minimizing the microbending loss of the fiber and the corrosion of the fiber under stress, moisture, and moisture.


Classification of optical fiber filling compound

Fillingcompound is divided into fiber compound and cable compound, and the fiber compound is directly in contact with the fiber. It is suitable for use in fiber loose tube or large bundle tube and ribbon optical fiber cable. Mainly to protect the optical fiber in the tube, such as the flexibility and bending properties) and cable compound (not directly with the fiber contact, suitable for the optical cable, cable core clearance and coated on the core packaging surface, used to prevent water penetration into the cable); From the point of view of the thixotropy of the filling compound, it can be divided into thixotropic and non-thixotropic type; from the composition point of view, it can be divided into mineral ointment, synthetic ointment and silicone ointment (good performance but expensive price, a small proportion) .


Optical fiber cable filler characteristics analysis

1.The ideal buffer material of optical fiber cable can make the optical fiber from the microbending loss caused by external stress damage;

2.Moderate viscosity, strong thixotropy, can be filled at room temperature;

3.Water swelling and water blocking type: fast water absorption, high water absorption, good water blocking performance; thermal expansion and water blocking type: rapid thermal expansion, uniform expansion, not hard and brittle;

4.Excellent temperature performance, and long-term stability;

5.Has good compatibility with optical cable materials, small acid value, oxidation resistance, etc.

6.Good craftsmanship and quality stability.


Filling compound on the performance of fiber optic cable:

1.The flash point is too low to be flammable;

2. If the dropping point is too low, it is easy to drip at high temperature;

3.The increase in light loss due to excessive hydrogen evolution occurs;

4.Poor compatibility with optical cable components (materials) will deform the components, reduce strength and elongation, and affect the service life of the optical cable.

The various properties of the optical fiber cable filler are also related, and often an improvement in one characteristic is accompanied by a decrease in another characteristic, and an increase in dropping point may reduce the penetration.

Apple abandons the $1 billion Irish data center plan

Foreign media reported on the 10th that Apple released an announcement on Thursday local time, saying that due to the delay in the review process, Apple decided to abandon the data center construction plan in Ireland, and the investment budget of Apple’s data center plan with Ireland is set to be 1 billion US dollars.

Foreign media reported that Apple had announced in February 2015 that it plans to build a data center in a rural area in western Ireland. At the same time, Apple said it will use nearby green energy, but the plan was met with opposition from local environmentalists. Because approvals were delayed for two years, Apple has finally issued a statement saying it has to give up its plan to build a data center in Ireland.

On April 25th, Apple decided to start paying the Irish government a tax refund of 13 billion euros and the corresponding late fees from the Irish government in May. However, Apple said that the money should be placed on third-party accounts first. Nineteen months ago, the European Union ruled that Apple illegally obtained 20 years of tax assistance from the Irish government in Ireland through a taxation mechanism that does not exist in other EU countries.
