What is the difference between indoor and outside cables

The difference between indoor cables and outside cables. Generally, outside cables are designed to resist water penetration by using a gell fill or dry water-blocking compounds and a polyethylene jacket.

 

The new dry cables are getting very popular, since they can be made as distribution types which are easier to terminate.

 

Many also have a PE jacket over a UL-rated PVC jacket so you can bring the cable into the building, strip off the outside jacket and run it anywhere in the building (not the 50 feet limit of PE.)

 

Indoor or premises cable must be rated for flame retardance for safety and to meet code.

Tight Buffered Fibre

Tight buffered fibre is manufactured by extruding a layer of buffer material (PVC, LSZH, ETFE, etc) on the  sruface of the fiber. Through the selection of high-quality material, dedicated equipments and precision moulds for production, the tight buffered fibre delivers excellent performance.

Simplex Cable(GJFJV)
The Simplex cable uses single 900μm or 600μm tight buffered fibre as optical transmission medium, covered with aramid yarn as Strength member, then extruded with a PVC sheath. Other sheath materials, like LSZH and TPU, are available on request.

A brief introduction of the optical fiber terminal box

The o ptical fiber terminal box adopts the design of high density and large capacity. It has a nice appearance and it has the features that are reasonable distribution, easy to find, easy to manage, easy to install and good operability. The optical fiber terminal box can be divided into: 1x8, 1x12, 1x24 and 1x48 optical fiber terminal box.

The manufacturing process of the optical cable

The manufacturing process of fiber optical cable generally includes:   Firstly , is the selection of fiber optical cable. We should choose the fiber with excellent feature of transmission and the qualified tension.   Secondly , we dye the fiber. We identify the fiber cable with the standard chromatography. And the fiber cable must be not fade and migration in high temperature.   Thirdly is the secondary extrusion. We use the plastic with high elastic modules and low coefficient of linear expansion and extrude it into the pipe with a certain size.And we fill the fiber and the moisture-proof and waterproof gel into the pipe. Then we store it a few days (not less than two day).

The MTP adapter technology of fiber optical module makes progress

At present, the MTP adapter technology of fiber optical module, which is independent research and development by China, achieves a new progress based on the original single transceiver module and reaches the domestic leading level.   The existing production of MTP adapter has been able to meet the needs of producing the fiber optic module of a variety of models and specification. And it has formed a certain capacity of mass production; the annual output reaches tens of thousands.   The MTP adapter production technology of fiber optical module uses the domestic equipments and raw materials to replace the expensive imported equipments and raw materials.   Each of the imported
