This content is about 4 what you should know features about G 657 A/B bare fiber in OSP networks.

1. What you should know is about the G.657 standard was developed by the International Telecommunications Union (ITU) to provide consistency in the evolving requirements for bend-insensitive singlemode fiber. This class of fiber enables cost reductions through compact cable designs, reduced space requirements and more relaxed deployment requirements.
It includes these G.652D-compliant designations for long reach applications:
• G.657.A1 (10 mm minimum design radius)
• G.657.A2 (7.5 mm minimum design radius)
and these G.652-compatible designations for short-reach (< 1 km) drop applications:
• G.657.B2 (7.5 mm minimum design radius)
• G.657.B3 (5 mm minimum design radius)

2. What you should know is about the industry’s first full-spectrum ZWP single-mode fiber exceeds the requirements of the G.657.A standard and is fully compatible with G.652.D fibers. a truly “bend-optimized” fiber. This G.657.A1 fiber offers low attenuation, excellent macrobend performance (which also guards against any long-term reliability threat from risky bends), exceptional PMD, and is fully splice-compatible with the existing installed base of fibers.

3. What you should know is that for in-building, central office and cabinet applications, bending optimized fiber offers enhanced bend performance ideally suited for in-building and connectivity applications and full compatibility and compliance with the installed base of conventional G.652.D single-mode fibers. It is an excellent choice for OSP drop cables for Fiber-to-theHome (FTTH), cell sites, enterprise networks, or any application where small bend diameters may be encountered.

4. What you should know to Recognizing the need to speed and simplify MDU in-home wiring applications, G 657 Fiber which allows optical cables to be bent and routed in ways never before feasible with traditional drop cables. G.657.B3 solution, can be bent to a 5 mm radius and stapled, with negligible signal loss and no degradation in
transmission quality, offering reliable support for such FTTH applications as high-definition television, on-demand video, ultra high speed data, voice, and online gaming.
