Please be respectively equipped with sheath extension in optical cable both sides, can not only effective protection optical cable, while can also prevent optical cable be pressurized sliding.
The purpose of this utility model is achieved through the following technical solutions：
Inside cable under a kind of twin-core blanket with sheath extension, including the first sheath extension, the second sheath extension,
First circular optical cable part and the second circular optical cable part, the first circular optical cable part and the second circular optical cable part bonding composition
Ribbon optical fiber cable component, the first circular optical cable part and the second circular optical cable part respectively includes tight tube fiber, aramid yarn adds
Strong element layer and restrictive coating, the tight tube fiber include bare fibre, coat and fixed coating successively from the inside to the outside；Described
One sheath extension and the second sheath extension are respectively arranged on the first circular optical cable part and the second circular light by connector
The both sides of cable part, the first sheath extension, the second sheath extension, the first circular optical cable part and described second
The central point of circular optical cable part is located on same axis.
In the present invention, the cross section of the first sheath extension and the second sheath extension is one end
The small pyramidal structure of the big other end, the sheath extension can effectively prevent optical cable and slided by external force.
In the present invention, the first sheath extension, the second sheath extension and the restrictive coating are
PVC oversheaths, LSZH oversheaths or TPU oversheaths, with good flame retardant property and mechanical performance.
The utility model has the beneficial effects that：
（1）By the first circular optical cable part and the second circular optical cable part bonding composition ribbon optical fiber cable component so that optical cable
Component has bearing capacity, while being equipped with multilayer coating structure layer so that has stronger mechanical performance and environmental performance；
（2）It is respectively equipped with the first sheath extension and the second sheath extension in ribbon optical fiber cable component both sides so that optical cable
Component is suitable for laying under blanket, and will not be moved with being pressurized, and enhances the safety and reliability laid under blanket.
