A bare fiber, a core with its cladding surrounded by a coating-is still very sensitive to the adverse environment regardless of
how perfect the coating is . Thus , in practice, you will find a fiber only in some protective enclosure, which is called fiber-optic cable,
Since optical fiber is the main transmission medium in modern telecommunications .
Bare glass fibers are based on silica or other glass materials. The glass surface is susceptible to abrasion and mechanical flaws.
To protect the cable from the environment, the buffer coating or jacket fits over the core and cladding.
The diameter ranges from 250μm to 900μm, usually 250um for single mode and multimode fibers, but 400um is also very common in polarization maintaining fibers. It provides mechanical protection while allowing for flexibility in the fiber.
Description and Application
G655 fiber (Large Effective Area High Capacity Positive Dispersion Shifted Single-mode Fiber) is comprehensively optimized for attenuation
and dispersion performance at the 1550nm operating wavelength. The fiber has the lowest attenuation and moderate dispersion at 1550nm,which enables excellent performance in multi-channel Dense Wavelength Division Multiplex (DWDM) systems traditional operating in the C-band(1530nm-1565nm),as well as in emerging L-band(1565nm-1625nm)system.
Application
G655 fiber is the commercialized fibre that has the largest effective area in the G.655 series. This fiber is suitable for application of high output power Erbium Doped Fibre Amplifier (EDFA)and multi-channel Dense Wavelength
Division Multiplex(DWDM), and can be effectively applied in the high bit-rate both single-and multi-channel, long distance digital transmission links even without dispersion compensation .
Norms
G655 fibre complies with or exceeds the ITU-T Recommendation G.655 Optical Fibre Specification . we tightens many parameters of fiber products so as to offer more conveniences to customers .
Process
G655 fibers are manufactured using the advanced Plasma Activated Chemical Vapor Deposition (PCVD)process. Because of the inherent advantages of the process, our fibres show extremely refined refractive index(RI)profile control, excellent geometrical performance,low attenuation, etc.
Characteristics
Being applicable in the high bit-rate operation across 1530-1565nm and 1565-1625nm band
Large effective area ensures good economic return from the transmission system
Low attenuation, low dispersion, low PMD and low zero dispersion slope that satisfy the demand of transmission links
Low bending induced loss at 1550 nm and at the more sensitive 1625 nm wavelength
