G.652D Product Model: GYFXTY 2~12C Our Ref: No.TS-FT V1.0 GENERAL 1.1 These optical cables have excellent protection, optical transmission and mechanical performance. 1.2 The cable differential is to be composed of a single loose tube. 1.3 This specification covers the construction and the properties of Single Tube Dielectric Optical Cable. 1.4 This cable shall be used for internal or external installation, such as local internal networks and FDDI networks. 1.5 This cable has transmission capacity in wavelength of 850nm, 1310nm or 1550nm. 1.6 Color pattern is the same as NBR 9140 (Brazillian Standard) 1.7 Applicable Specification: ETT 0011/95 (Telcon) CROSS-SECTION FIGURE Optical Fiber Jelly PBT loose tube PE shealth Aramid Yarn Figure 1, Cross-section of Cable (GYFXTY 12C)

2 OPTICAL FIBER IN CABLE (ITU- G.652.D) Optical properties of the SM fiber are achieved through a germanium doped silica base core with a pure silica cladding which meets ITU-T G652D, UV curable acrylate protective coating is applied over the glass cladding to provide the necessary maximum fiber lifetime. Geometrical, optical, and mechanical characteristics of fiber in cable as the following table: 3.1.

Remark: No attenuation changes is considered as the attenuation changes 0.05 db. ENVIRONMENT CONDITIONS The cable shall retain the optical properties, detailed in the present specification over the following: Installation temperature : -10 C to + 70 C Operating temperature : -20 C to + 70 C Storage / Shipping temperature : -20 C to + 70 C Relative humidity : 0 to 90 %

6 IDENTIFICATION MARKING Unless otherwise specified, the cable sheath marking shall be as follows: Color : white Contents: The name of manufacturer, the year of manufacture, the type of cable, length marking Interval: 1m PACKING AND SHIPMENT 8.1 Reel Length Standard reel length: 4 km/reel 8.2 Cable Drum The cable are packed in iron-wooden drums The minimum barrel diameter of the drum shall be more than 30times of the nominal diameter for armored cable, and 25 times of the nominal diameter for unarmored cable. 8.3 Labeling The direction of rotation of the color scheme is shown by marking the clockwise and anti-clockwise ends with red and green adhesive tape respectively. The markings are on both sides of the flanges as follows: Cable Type / Size Cable Length Gross Weight FUTONG GROUP Shipping mark 8.4 Packing Both cable ends are provided with protections against water penetration and firmly secured to the drum, so the cable cannot move and the turns cannot slide when it is moved, handled or laid. The inner end has at least 3 meters of accessible length to perform reception tests in the cables.
