All three share the same cable core and fibre performance, so the choice costs you only sheath and armour money.\"}},{\"@type\":\"Question\",\"name\":\"What fibre counts can you produce?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"24 to 576 cores in loose-tube stranded designs (4\u00d76 up to 24\u00d724 tube configurations). Centre-tube designs (GYXTW) cover 2\u201324 cores for access networks. Ribbon designs (GYDTA \/ GYDTS) for high-count backbones on request.\"}},{\"@type\":\"Question\",\"name\":\"Which fibre type should be specified \u2014 G.652D or G.655?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"G.652D is the default for metro, access and FTTH: lowest cost, full 1310\/1550 nm windows. G.655 (NZDSF) suits long-haul DWDM links where dispersion management matters. For FTTH drop and in-building runs, ask for G.657A1\/A2 bend-insensitive fibre.\"}},{\"@type\":\"Question\",\"name\":\"Can the cable be supplied with LSZH sheath for tunnels?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. Flame-retardant LSZH sheathed versions are produced against confirmed specification, with IEC 60332-3 flame performance and IEC 61034 \/ 60754 smoke and halogen verification.\"}}]}<\/script>\n<!--
