Enhanced Single-Mode Optical Fiber

Enhanced Single-Mode Optical Fiber
Product description

ESMF (Enhanced Single-Mode Fiber) provides improved performance across the entire 1260 nm to 1625 nm wavelength spectrum for use in metro, access, and long-haul networks. It has low dispersion in the 1310 nm window and low attenuation in the 1383 nm water-peak region, allowing use of the extended band (1360 nm to 1460 nm). With its wide operating spectrum, ESMF expands the fiber's future growth capability and allows flexible configuration of voice, data, and video services within the fiber. It can be used in all cable constructions, including loose lube, tight buffered, ribbon, and central tube designs. 

The tighter geometrical, attenuation and PMD specifications of ESMF enable superior performance in long-haul, metropolitan, access and premises applications in telecommunications, CATV and utility networks. ESMF is completely interchangeable with standard single-mode fiber. 

Prysmian's Advanced Plasma Vapor Deposition (APVD™) manufacturing process ensures the highest quality and purity of fibers. Proprietary ColorLock™ coating process further enhances the performance, durability and reliability of the fiber, even in the harshest environments.

 

Features and Benefits 

  • Low 1383 nm (Water-Peak) Attenuation
    • Provides expanded fiber capacity and cost savings through the use of cheaper lasers in the entire 1260 to 1625 nm range, multiplexing filters and a higher number of channels.
  • Low hydrogen sensitivity
    • Low attenuation in the 1383 nm region even as the fiber ages, for improved performance and long life.
  • Lower PMD of 0.06 ps/km Link Design Value
    • Extends the PMD distance performance, reducing regeneration costs.
  • Proprietary PCVD and 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, thereby enhancing fiber identification and the reliability of colored fibers. Consistent, vibrant color for ease of use and flexibility.
