Unitube Light-armored Fiber Ribbon Cable GYDXTW

 GYDXTW  central tube Optical Fiber Ribbon Cable

GYDXTW Fiber  optic cable is an outdoor communication optical cable of metal strength menmber of the central tube jelly-filled structure with embedding steel-polyethylene laminated shenth, consisting of the central loose tube, two parallel steel wire strength members, and sheath. The fiber ribbons are positioned in the loose tube. The tube is made of high modulus plastics (PBT) and filled with water resistant filling gel. The corrugated steel tape is longitudinally applied over the loose tube, and combined with a durable polyethylene (PE) sheath. Two parallel steel wires are embedded in two sides of PE sheath.

  Features and benefits:

• Mature ribbon technology provides good transmission performance

• Accurate fiber excess length control ensures excellent mechanical and temperature performance

• Special filling compound filled loose tubes provide perfect optical fiber protection

• All section water blocking and longitudinally corrugated steel tape armor provide good performance of moisture-proof and water block

• Two parallel steel wires provide desirable tensile strength and crush resistance

• Easy identification, branching & maintenance save splicing time and reduce project cost

• Suitable for Access network (especially in FTTC and FTTB applications), interoffice connection and CATV network

• Strict craft and raw material control enable lifespan over 25 years

  Performance:

  Applications: Suitable for long-distance communication and indoor communication Way of laying: overhead, pipeline Operating temperature: -30 ~ + 70 °C

• Note:1.suffix Xn denotes fiber type and see details in FOCC's cable coding illustration

•          2.the colour arrangement of fiber and tube is specified in the colour identification table.

Fiber coloure Identification of loose tube with FOCC

the fibers in cables can be identified by standard colour identification in compliance with YD/T901-2001 Standard.

Standard colour Identification

Note: A. when the fiber count of one loose tube is less than 12, the fibers are identified form the NO.1 colour on a stream.

         B.in standard colour identification, the NO.6 white colour could be replaced by nature colour,which called standard colour identification W.
