Single Mode G.652.D Optical Fiber
Sinocomms' G.652.D single-mode optical fiber is designed specially for optical transmission systems operating over the entire wavelength window from 1260nm to 1625nm. By suppressing the water peak that occurs near 1383nm in conventional single mode fiber due to hydroxyl (OH-) ions absorption, G.652.D fiber is able to open E-band (1360nm-1460nm) for operation, and consequently provides 100nm more usable wavelengths.
Sinocomms tightens many parameters of optical fiber products so as to offer more conveniences to customers.
