| Low Water Peak Single Mode Optical Fiber [LWPF] |
LWPF is designed to provide improved performance across
the full wavelength region form 1265 to 1625nm.
LWPF fully meets ITU-T G.652 and is available for use in
loose tube cable, ribbon and other cable designs.
It use ultra-pure materials based on silica, so this optical fiber
has excellent optical and mechanical performance.
