Smaller bending radii, improved attenuation properties and higher transmission quality are the significant benefits passed on to Datwyler's customers, the company reckons, as it switches to two new single-mode fibers based on G.652.D (BLO) and ITU-T G.657.A2 fiber.

According to a press release, in the future, the company's fiber-optic (FO) indoor cables -- previously incorporating bend-optimized single-mode ITU-T G.657.A1 fiber -- will be supplied as standard by Datwyler with bend-optimized G.652.D bend-loss optimized (BLO) fiber, or optionally with bend-optimized ITU-T G.657.A2 fiber. The latter has been tried and tested in FTTx networks and data centers, notes Datwyler, with users benefitting from a low bending radius of 10 to 7.5 mm for added operational safety.

The company clarifies that its FO Universal and FO Outdoor series cables will now no longer be offered with ITU-T G.657.A1 fiber but, from now on, in addition to ITU-T G.652.D, will be available with G.652.D BLO fiber.

"The convincing argument for this new fiber is not only that it has improved attenuation properties, e.g. ≤0,21 dB/km @ 1550 nm (installed), but also that it incorporates the essential advantages of the 'old' fibers, namely the comparatively large-mode field diameter of G.652.D and the low bending losses of G.657.A1," commented a Datwyler representative.

The representative added that planners and network operators of LANs, data centers, FTTx and city networks "will gain from using the cables with the new G.652.D (BLO) fibers, in that they no longer have to allow for additional attenuation losses when connecting fibers of different mode field diameters. These fibers therefore give them and the companies installing them a greater safety buffer."
