Corning® SMF-28e® Optical Fiber
Evolving Networks Now
As the global standard of excellence for standard single-mode fiber, Corning® SMF-28e® fiber is the most
demanded optical fiber in the world. SMF-28e fiber was introduced in 2001 as the enhanced version of
the trusted SMF-28® fiber, Corning’s flagship standard single-mode product for nearly two decades.
Every day, moreSMF-28e fiber is deployed than any other optical fiber product because customers value
the industry-leading product specifications backed by the world leader in optical fiber.
SMF-28e fiber is advancing communications applications worldwide by
evolving networks to a higher level of performance capability. While
traditional standard single-mode fibers are designed for use
in only the original &conventional transmission bands,
SMF-28e fiber enables flexible networks that can operate
throughout the single-mode fiber operating window.
SMF-28e fiber is optimized for widespread deployment
in metropolitan and access networks, where complete
compatibility with existing infrastructure coupled
with the ability to deploy advanced services or new
cost-saving technologies enables maximumreturn
on investment.

Standards Evolution Opens New Opportunities
The optical communication industry agrees that fiber design must continually evolve to stay aligned with
advancements in network design. International fiber standards have most recently been updated to reflect
the full-spectrum capability of current-generation standard single-mode fibers. Full-spectrum fibers have
permanentlyreduced attenuation in the water peak region as compared to conventional fibers.
Full-spectrum fibers are being rapidly
adopted by network operators to take
advantage of current generation technology while ensuring compatibility
with legacy systems and interoperability with the installed base of conventional single-mode fiber.

Both the International Telecommunications Union (ITU) and the International Electrotechnical Commission
(IEC) have incorporated reduced
water peak requirements into fiber and
cable specifications.Corning used its unmatched experience in the manufacturing of optical fiber to evolve standard singlemode fiber to meet and exceed the highest industry standards. 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.
