GL FIBER® fibre is designed specially for long-haul optical transmission systems. It makes performance optimization in both C band (1530-1565nm) and L band (1565-1625nm). Its enlarged effective area suppresses nonlinear effect in the process and increases nonlinear tolerance for transmission system. Meanwhile GL FIBER® fibre reduces attenuation in both C band and L band. The fibre fully meets the demands for transmitting signal with high speed, high capacity and extended networking distances over one single fibre.

Applications

GL FIBER® Fiber is the ideal solution for high-performance applications, including Ethernet, IP networks, SONET, and WDM, thanks to its expansive effective area and superior low-attenuation characteristics.

GL FIBER® Fiber enhances system performance by supporting high input power and reducing power distribution density through its enlarged effective area. This design effectively suppresses nonlinear effects such as Brillouin scattering, self-phase modulation, and cross-phase modulation, making it well-suited for multi-channel DWDM systems.

Additionally, GL FIBER® Fiber delivers ultra-low signal attenuation, meeting the stringent requirements for long-haul optical transmission while providing greater system redundancy.

Standards

GL FIBER® fibre complies with or even exceeds the ITU-T G.654.B/E recommendation and IEC 60793-2-50 B1.2 Optical Fibre Specification. GL FIBER tightens many parameters of fibre products.

Characteristics

• Designed for 40G/100G/ 100G beyond large capacity, long haul Dense Wavelength Division Multiplexing (DWDM) system operation over C band (1530-1565nm) and L band (1565-1625nm)
• Large effective area reduces nonlinear effect in the transmission process, ensuring good system performance
• Lower attenuation level, which meets the demand of extended long distance transmission
• Lower bending induced loss at 1550nm and more sensitive 1625 nm window.
