Product Details

Description:

GL FIBER® low water peak dispersion unshifted Single-mode fibre is designed specially for optical transmission systems operating 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® fibre is able to open E-band (1360-1460nm) for operation, and consequently provides 100 nm more usable wavelengths.


Applications:

Thanks to its broad usable optical spectrum and outstanding optical performance, GL FIBER® fibre is the optimum choice that supports various applications such as Ethernet, Internet Protocol (IP), Asychronous Transfer Mode (ATM), Synchronous Optical Network (SONET) and Wavelength Division Multiplexing (WDM). GL FIBER® fibre provides more bandwidth for backbone, metropolitan area and access networks.


Feature Characteristics:

1. Designed for operation over the full optical spectrum from 1260-1625 nm, which provides 50% more usable wavelengths and hence the transmission capacity is increased
2. Outstanding optical performance supporting high-speed transmission technologies such as DWDM and CWDM
3. Being compatible with existing 1310 nm equipment
4. Good protection and excellent strip force stability
5. Accurate geometrical parameters that insure low splicing loss and high splicing efficiency

Standards

GL FIBER® fibre complies with or exceeds the ITU-T Recommendation G.652.D and the IEC 60793-2-50 typeB1.3 Optical Fibre Specification. GL FIBER® tightens many parameters of fibre products so as to offer more conveniences to customers.
