通信ネットワークやデータネットワークの加入者同士でデータや音声を迅速かつ安全に転送する際、パッシブ光ファイバ／メタルネットワークの構成要素は、アクティブディストリビューション・スイッチングシステムと同じくらい重要です。
ファイバ・ツー・ザ・カーブ（FTTC）は、高度な光ファイバ／メタルや同軸ケーブルのハイブリッドネットワーク・アーキテクチャであり、従来のレガシーメタルネットワークを超えるブロードバンドネットワークを実現します。このアーキテクチャは、交換局から家の前の縁石（curb）まで敷設されたインフラを使用し、既存のメタルや同軸インフラを利用して契約者にサービスを提供します。
当社は、レガシーのメタルからFTTC、FTTHインフラへの移行を支援することができます。
レガシーメタルネットワークからの移行には、光インフラの専門知識を持つサプライヤーが必要です。当社のオンラインカタログをご覧いただき、お客様のネットワークをネクストレベルに引き上げるのに役立つ製品をご確認ください。
Product Highlights
Lowest loss of any 80 µm2 terrestrial-grade, single-mode fiber
Learn MoreCorning’s SMF-28® ULL optical fiber portfolio has the lowest-loss 80 µm2 terrestrial-grade fibers available in the market – with millions of kilometers sold and deployed worldwide in the harshest environments and most demanding terrestrial core networks.
Compliant to ITU-T G.654.C, this ultra-low-loss fiber can be leveraged to extend network span lengths, skip amplification sites, upgrade to faster bit rates, add network components for improved flexibility, and/or lengthen the distance between regenerators.
Low-loss, large effective area terrestrial G.654.E compliant fiber
Learn MoreThe superior attributes of TXF® optical fiber, compliant to ITU-T G.654.E, allow for the provision of an additional network margin that can be leveraged to enable reliable, high-data-rate transmissions over longer spans and extended reach. This allows long-haul networks with TXF fiber to be designed more efficiently, reducing the need for amplification sites, which is particularly important in remote territories with challenging terrains. TXF fiber also minimizes the number of needed regenerators, even as higher data rate upgrades are planned with more stringent OSNR requirements.
Ultra-low-loss, large effective area terrestrial G.654.E-compliant fiber
Learn MoreIntroducing the latest innovation in Corning’s subsea portfolio, a 125 µm2 effective area with lowest loss. This fiber is designed for high-capacity long-haul networks and subsea systems. Compliant to ITU-T Recommendation G.654.B and G.654.E and available in a smaller, 200 µm outer diameter.
World’s most widely deployed, non-zero dispersion-shifted fiber
Learn MoreCorning® LEAF® optical fiber is the world’s most widely deployed non-zero dispersion-shifted fiber (NZDSF). Typically deployed in non-coherent long-haul and metro networks, LEAF fiber combines low dispersion and low loss. This ITU-T G.655.D-compliant fiber enables improved performance flexibility and compatibility with emerging network technologies with industry-leading performance.
LEAF fiber is built to withstand decades of demands in challenging environments and can be used in multiple network architectures. It can help existing networks evolve from 10G to the 40G and 100G systems of the future.
