BendBright™ A1 Single-Mode Optical Fiber

Prysmian BendBright™ A1 Single Mode Fiber
Product description

BendBright™ A1 fiber encompasses all the features of ESMF Optical Fiber (Enhanced Single-Mode Fiber) and provides high resistance to macro-bend losses, particularly in the 1600 nm wavelength region. 

This fiber can be used in all cable constructions, including loose tube, tight buffered, ribbon, and central tube designs. It supports long-haul, metropolitan, access and premises (FTTH) applications in telecommunications, CATV, utility and intelligent traffic networks. 

Using wavelengths in the L-band is a challenge for standard fiber, due to its macro-bend sensitivity. BendBright™ meets and exceeds this challenge. 

BendBright A1 fiber is further enhanced with Prysmian’s proprietary ColorLock™ coating. This coating enables optimum fiber performance, reliability and durability, even in harsh environments.

 

Features and Benefits 

  • Low bending losses
    • Up to 1/10th the bending loss of standard single mode fiber provides improved system performance.
  • Low bending loss at 15 mm bend radius; 10 turn loss ≤ 0.25 dB at 1550 nm.
    • Specified down to a 10 mm bend radius; 1 turn loss ≤ 0.75 dB at 1550 nm.
    • Allows a smaller bend radius with small diameter cables such as high density micro cables, patch cords and distribution cables.
    • Improperly installed small diameter bends result in lower attenuation impacts on systems.
    • 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 temperature cycling and mid-span express tube routing loss performance providing long-term attenuation stability.
  • Lower PMD of 0.06 ps/√km Link Design Value
    • Extends the PMD distance performance, reducing regeneration costs.
  • Improved Geometrical Parameters
    • Low splice loss and high splice yield.
  • Proprietary APVD™ Manufacturing Process
    • Superior geometry, uniformity and purity.
  • Revolutionary ColorLock™ Coating Process
    • Increased reliability, durability, and superior aging performance, resulting in lower maintenance and replacement costs. Makes color a component of the coating, thus enhancing fiber identification and colored fiber reliability. Consistent, vibrant color for ease-of-use and flexibility.
