Corning SMF-28e+ optical fiber is an evolutionary product that builds on over 15 years of proven performance from SMF-28 optical fiber. It addresses the transmission potential of full spectrum, optical transmission by eliminating high attenuation in and around the water-peak region (1360 nm - 1460 nm).

SMF-28e fiber is compliant with the new International Telecommunication Union (ITU) standards for low water-peak fibers, ITU G.652.C, as well as Telecommunications Industry Association and Electronic Industries Alliance (TIA/EIA) standards.

The fiber provides network planners with versatility and flexibility to grow their cost-sensitive systems as the demand from their customers grow. SMF-28e fiber has unsurpassed specifications to enable optical transmission throughout the entire single-mode operating window and is optimized for 16+ channel coarse wavelength division multiplexing (CWDM) networks.

This premium attenuation fiber is suitable for transmission applications in the access and metropolitan/access application spaces. SMF-28e fiber is suitable for various applications with link lengths less than 80 km and data rates around 2.5 Gbps.

While providing compatibility with carriers' legacy systems, SMF-28e fiber is optimized for various CWDM applications and provides flexibility and versatility in network design, as it enables the use of the full transmission window.

This means network designers will be able to implement network strategies that use current technologies and at the same time serve as an upgrade path for future network needs. The synergies created by the combination of SMF-28e fiber and CWDM will enable carriers greater transmission capacity and lower system cost.

As the first manufacturer to upgrade standard single-mode fiber worldwide, Cornign is providing customers with greater value today and in the future. Corning SMF-28e+ fiber is:

  • Corning's standard single-mode fiber offering, delivering optimized capability, network design flexibility and confidence in long-term performance
  • The world's most widely demanded full-spectrum fiber
  • In compliance with or exceeding the industry's most stringent requirements, including:
    • ITU-T G.652 (Categories A, B, C & D)
    • IEC Specifications 60793-2-50 Type B1.3
    • TIA/EIA 492-CAAB
    • Telcordia's GR-20
  • The industry leader in comprehensive standard single-mode fiber specifications

As Corning's premier standard single-mode fiber, SMF-28e+ fiber is one in a long line of optical innovations. Corning SMF-28e+, an ITU-T G.652.D-compliant optical fiber, is expanding the capability of the world's most dynamic metropolitan and access networks.

SMF-28e+ fiber conforms to the major optical fiber industry standards including ITU-T G.652 (Categories A, B, C & D), IEC 60793-2-50 (type B1.1 & B1.3) and TIA/EIA-492CAAB fiber.
