SMF Single mode Optical Fibre Low Water Peak G652D

Short Description:

G652D single mode fiber is 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, fibre is able to open E-band (1360-1460nm) for operation, and consequently provides 100 nm more usable wavelengths.

Application

Thanks to its broad usable optical spectrum and outstanding optical performance, this 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). this single mode fibre provides more bandwidth for backbone, metropolitan area and access networks.

CABLE DESIGN

Complies with or exceeds the ITU-T Recommendation G.652.D and the IEC 60793-2-50 typeB1.3 Optical Fibre Specification
