Application Notes: AllWave® FLEX Fiber and the G.657 Standard
The G.657 standard was developed by the International Telecommunications Union (ITU) in 2006 to provide consistency in the evolving requirements for bend loss insensitive single-mode fiber. OFS was an active participant in the development of the ITU-T G.657 standard, and our AllWave FLEX Zero Water Peak Fiber exceeds its requirements, while maintaining full compatibility with G.652.D fibers. A truly “bend-optimized” fiber, AllWave FLEX Fiber offers low attenuation, excellent macrobend performance (which helps guard against any long-term reliability threat from risky bends), and exceptional PMD for applications such as premises and FTTx where small bend diameters are encountered. It is fully splice-compatible with the existing installed base of single-mode fiber.

Ask the Experts: Measuring Attenuation
Question How is attenuation measured in optical fiber?
   
Answer
AttenuationAt OFS, we measure the attenuation of every spool of fiber using a standard cutback technique specified under Fiber Optic Test Procedure (FOTP) 78. This procedure also specifies the control of launch conditions in accordance with FOTP 50. Standards for measuring single-mode and multimode fiber have been established by the Telecommunications Industry Association (TIA) and adopted by the American National Standards Institute (ANSI). Equivalent standards are published internationally by the International Electrotechnical Commission (IEC). By following the standardized procedures, OFS is assured of achieving accurate, repeatable measurements.

Technical Topics: FOLS Updates its Premises Cost Model

FOLS LogoWhen designing a Local Area Network (LAN), network designers must balance the desire for performance, scalability, and flexibility with the need to be cost-effective. To help determine the best solution for their network, many designers are using the Premises Cost Model from the TIA’s Fiber Optics LAN Section (FOLS) to help them compare the installed first costs of several standards-compliant architectures. The FOLS Premises Cost Model, designed based on input from OFS and other manufacturers, compares the cost of a traditional hierarchical star architecture (UTP horizontal with fiber riser backbone) to other standards-compliant architectures. The model can be completely customized to each user’s installation.
