GYFTY Fiber Optic Cable is used for duct and aerial installation.The Optical fiber can be single mode and high silica material (based on ITU-T recommendation G652.D). This type of fiber optic cable is 12F,24F, 48F,96F,144F and 288F.
The Operation wavelengths of Single mode Optical Fiber should be 1310nm, 1490nm, 1550nm and 1625nm wavelength bands.
The geometric structures and optical characteristics should be as per ITU-T Rec. G652.D.
Technical properties:
All optical fibers with primary coating shall pass the proof test before cabling.
The tensile load carried for duration of approximately 1 second is less than 5N (about 0.4Gpa, 58Kpsi).
The proof strain of optical fiber shall not be less than 1%.
The minimum bending radius of the coated fiber should be less than 30mm.
All fibers used in the cable are color-coded with undeniable color to facilitate individual fiber identification, The colofcoding should be according to IEC 304 as follow:
No. of fibers | Color of fiber | No. of fibers | Color of fiber |
1 | Blue | 7 | Red |
2 | Orange | 8 | Black |
3 | Green | 9 | Yellow |
4 | Brown | 10 | Violet |
5 | Grey | 11 | Pink |
6 | white | 12 | aqua |
