Datwyler upgrades single-mode fiber cable lines

Oct. 5, 2015
Datwyler has added fiber-optic cables that feature G.652.D Bend Losses Optimized (BLO) and ITU-T G.657.A2 single-mode fibers to its fiber cable portfolio. The new fibers offer smaller bending radii, improved attenuation properties, and higher transmission quality, Datwyler says.

Datwyler has added fiber-optic cables that feature G.652.D Bend Losses Optimized (BLO) and ITU-T G.657.A2 single-mode fibers to its fiber cable portfolio. The new fibers offer smaller bending radii, improved attenuation properties, and higher transmission quality, Datwyler says.

The company says that it will replace its ITU-T G.657.A1 fiber cables with cables featuring G.652.D (BLO) fiber or, optionally in the case of its indoor cables, with bend-optimized ITU-T G.657.A2 fiber. Datwyler says it will make the change due to the superior performance of the new fibers versus the A1 fiber.

For example, the A2 fiber has demonstrate bending radius of 10 to 7.5 mm for added operational safety in FTTx and data center networks. For applications where the universal and outdoor cables would be used, G.652.D (BLO) fiber has demonstrated improved attenuation properties (e.g., ≤0.21 dB/km at 1550 nm installed) while maintaining the comparatively large mode field diameter of G.652.D and the low bending losses of G.657.A1.

Regardless of the application, deployers and planners will no longer have to allow for additional attenuation losses when connecting fibers of different mode field diameters, Datwyler says.
