G.652.D Fiber Optic Bare Fiber Low Water Peak Single Mode Optical Fiber
The Low Water Peak Single Mode Fiber G.652D Bare Colour Fiber Supports Ethernet, Internet, long-distance trunk communications, CATV, and WDM.
It can replaces standard single-mode fiber, can be used in all cable types including ribbon, slotted core, stranded, central tube, ADSS, OPGW, and internal tight buffer designs.The Low Water Peak Single-mode Fibre has low attenuation and excellent bending resistance and geometrical properties.
The T-OF002 G.652.D fiber optic Low water peak non-zero dispersion shifted single mode optical fiber, which complies with or exceeds the standard of ITU-T G.652D and IEC60793-2-50 B1.3 type optical fiber. It applied to the transmission system of full wavelength from 1260nm to 1625nm. It eliminates the assimilating water peak induced by OH- @ 1383nm of standard single mode optical fiber. And enlarges the work windows to E wavelength (1380nm-1480nm). The G.652.D optical fiber eigenvalue of attenuation and dispersion optimized at all wave length. Which satisfies the transmission demand of multiple channel and high speed.
This G652D Single-mode Low Water Peak Fiber is fully compatible with ITU T.G652D & ITU T.G67A1. Which is ideally designed for use in backhaul, metropolitan, and FTTX networks.
