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).


Finally, we twist the number of extruded fiber together with the strengthen unit and add a layer sheath around the cable.


We, Sopto, strictly adhere to the production process provide the standard fiber optical cable for you!

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

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.
