BendBright™ A1+ Bend Insensitive Single Mode Fiber with Uncabled Attenuation

BendBright A1+ fiber significantly exceeds the macrobend performance requirements of G.657.A1. BendBright A1+ fiber provides this increased macrobend performance while maintaining optimal splice compatibility with the installed base of Standard Single Mode Fibers. BendBright A1+ fiber meets and exceeds the requirements of G.657.A1 and G.652D. BendBright A1+ provides low bending losses down to a minimum bend radius of 10 mm.

Features and Benefits 

• Low bending losses
  • Low bending 1550 nm loss at 15 mm bend radius; 10 turn loss ≤ 0.05 dB. ITU G.657.A1 specifies 0.25 dB.
  • Specified down to a 10 mm bend radius; 1 turn loss ≤ 0.50 dB @ 1550 nm. ITU G.657.A1 specifies 0.75 dB.
  • Allows a smaller bend radius with small diameter cables such as high density micro cables, patch cords and distribution cables.
  • Mitigates losses caused by improper installations.
  • Allow the use of smaller splice trays or closures.
  • Provides lower bending losses at higher wavelengths such as 1625 nm which future proofs the network
  • Improves long-term attenuation stability by reducing losses related to temperature cycling and mid-span buffer-tube storage.
• Full backward ITU G.652.D SMF compatibility
  • Compliant with ITU G.652.D and IEC 60793-2-50 B-652.D low water peak SMF specifications.
  • Compatible with equipment designed for G.652 fibers; fully transparent from a transmission perspective.
  • Splice compatible with ITU G.652 SMF using standard single mode fiber machine settings.
  • Full 1260-1625 nm low water peak compliance.
