Which types of optical cables are used for the tpu outer sheath for optical cables?

　　TPU (thermoplastic polyurethane) outer sheaths for optical cables are widely used in a variety of types of optical cables due to their wear resistance, tensile resistance, flexibility, and excellent moisture and flame retardancy properties, especially those that require high mechanical protection and harsh environmental adaptability. Here are some cable models that may use TPU outer sheaths:

　　Armored field fiber optic cable: such as GJYPJH-2B1 and other models, this type of fiber optic cable is usually used in field wiring, emergency repair and other scenarios, and needs to have good wear resistance, tensile resistance and flexibility to adapt to complex and changeable field environments. TPU outer sheath can effectively protect the cable from external damage and improve the service life of the cable.

　　Other special-purpose optical cables: such as ADSS (all-dielectric Self-supporting) power optical cables, OPGW (fiber optic composite overhead ground wire) optical cables, etc. These optical cables are usually installed on power lines and need to withstand greater mechanical stress and harsh climatic conditions. The TPU outer sheath can meet these special needs due to its excellent physical properties and weather resistance.

　　In addition, the TPU outer sheath is also widely used in optical cables that require a higher fire rating due to its good flame retardant properties, such as flame retardant optical cables GYTZA.

　　It is important to note that the choice of cable type and outer sheath material is usually determined according to the specific application scenarios and needs. Therefore, in practical applications, the most suitable cable type and outer sheath material should be selected according to factors such as the use environment, tranSMission requirements and cost of the cable.

　　Overall, the TPU outer sheath has been widely used in various types of optical cables due to its various excellent properties, providing effective protection and support for optical cables.
