G.652.D Plus Low Loss Single-mode Fibre

Optical fibers are basically composed of two coaxial layers: core and cladding. The core is the inner part of the fiber, which guides light, whereas the cladding surrounds it completely.

Feiboer Plus Low Loss Single-mode Fibre is designed specially for optical transmission systems* which operates over the entire wavelength window from 1260 nm to 1625 nm. By suppressing the water peak that occurs near 1383 nm in conventional single mode fibre due to hydroxyl (OH-) ions absorption, GL FIBER© Plus Fibre is able to open E-band (1360 to 1460nm ) for operation, and consequently provides 100 nm more usable wavelengths. GL FIBER® Plus Fibre is effectively optimized for much lower attenuation level across the entire wavelength window from 1260 nm up to 1625 nm.

Thanks to its broad usable optical spectrum and outstanding attenuation performance, Feiboer Plus Low Loss Single-mode Fibre is the optimum choice that supports various applications such as Ethernet, Internet Protocol (IP), Asychronous Transfer Mode (ATM), Synchronous Distribution Network (SDH) and Wavelength Division Multiplexing (WDM). Feiboer Plus Low Loss Singlemode Fibre provides wider bandwidth and much lower signal attenuation for backbone, metropolitan area and access networks.

• Designed for operation over the full optical spectrum from 1260-1625 nm, and hence the transmission capacity is increased
• Much lower attenuation over the full optical spectrum from 1260 nm to 1625 nm, which meet the demand of extended long distance transmission
• Outstanding optical performance supporting high-speed transmission technologies such as DWDM and CWDM
• Being compatible with existing 1310 nm equipment
• Good protection and excellent strip force stability
• Accurate geometrical parameters that insure low splicing loss and high splicing efficiency
