Welcome To Twentsche (Nanjing) Fibre Optics Ltd. (for short: TFO)！
Several fibers are coated in a soft tube unit, it’s called micro bundle unit. Several microbundle units wrapped a layer of swelling tape and two ripcords. A corrugated steel tape is applied around it. Two parallel steel wires are placed at the two sides and the cable is completed with an outer sheath.
Characteristics：
1.Excellent mechanical performance, especially crush resistance performance, it is suitable for direct buried
2.Excellent temperature performance, reach to -45℃
3.Very soft micro bundle unit, convenient installation
4.Corrugated steel tape can prevent moisture, rodent and better crush resistance
5.Parallel high modulus steel wires as strength member to withstand axial loads
6.Outer sheath protects cable from ultraviolet radiation
Installation：Direct buried, Duct, Aerial
Applications：Long distance, LAN communication
Temperature Range：Transportation：-45~+70℃；Installation：-5~+50℃；In use：-45~+70℃
