Smart Product Number: 1550B-HP
1550 nm Select Cutoff Single-Mode Fiber
Nufern’s 1550B-HP high-performance select cutoff bend insensitive single-mode fiber is optimized for use in small form factor active and passive components requiring tight bend radii. With a bend loss considerably lower than SMF-28™, 1550B-HP is ideal for the video leg in FTTH CWDM and applications such as smaller form factor C and Lband components and low NA planar waveguides.
