Description

高速データレート光伝送システム、例えば１００ギガビット（１００Ｇ）光ファイバネットワークの場合、予想ラインカードコネクタインターフェイスの１つは、２４心の多心プッシュオン（ＭＰＯ）コネクタ、例えばＭＴＰ（登録商標）コネクタである。これは、潜在的に問題であるが、その理由は、既存のネットワークシステム及び高速データレート光伝送システム向きに設計されたネットワークシステムの中には、１２心ＭＰＯコネクタを利用しているものがあるからである。同様に、２４心幹線接続方式が実施される場合、アクティブ組立体、例えばトランシーバ相互間の光ファイバ極性を維持する接続を可能にする２４心‐２４心パッチコードは、高速データレート光伝送システムの実施を容易にすることになる。 High data rate optical transmission systems, for example, in the case of 100 gigabit (100G) optical fiber network, one of the expected line card connector interface 24 fibers multifiber push-on (MPO) connector, for example, MTP (TM) connector is there. This is potentially a problem because some existing network systems and network systems designed for high data rate optical transmission systems utilize 12-core MPO connectors. Because. Similarly, when a 24-core trunk connection scheme is implemented, an active assembly, such as a 24-fiber to 24-fiber patch cord that allows connections to maintain fiber optic polarity between transceivers, is used in high-speed data rate optical transmission systems. Implementation will be facilitated.

本明細書で説明する組立体、システム及び方法は、一般に、高速データレート光伝送システム、例えば情報を例えば１０ギガビット（１０Ｇ）〜１２０Ｇの速度で光学的に転送することができるシステムに関する。典型的な高速データレート光伝送システムでは、多数のチャンネルが設けられ、各チャンネルは、選択されたデータレートをサポートすることができ、全体的データレートは、チャンネルのデータレートに用いられるチャンネルの数を乗算して得られる値で定められる。例えば、高速データレート光伝送システムの典型的なチャンネルは、１０Ｇ通信をサポートすることができ、したがって、１２チャンネル型システムでは、通信データレートを１０Ｇから１２０Ｇまでの１０Ｇの倍数で調節することができる。これよりも多くのチャンネルが追加された場合又はチャンネル当たりのデータレートが異なる場合、他のデータレートが得られる。特定のシステムデータレートについて所与の範囲のオプションが存在し、４０Ｇ及び１００Ｇが可能性として存在する。 Assemblies, systems and methods described herein are generally high-speed data-rate optical transmission system, a system which can be optically transferred, for example information, for example 10 gigabit (10G) to 120 g rate of. In a typical high data rate optical transmission system, a number of channels are provided, each channel can support a selected data rate, and the overall data rate is the number of channels used for the channel data rate. It is determined by the value obtained by multiplying. For example, a typical channel of a high-speed data rate optical transmission system can support 10G communication, so in a 12-channel system, the communication data rate can be adjusted in multiples of 10G from 10G to 120G. . If more channels are added or if the data rate per channel is different, other data rates are obtained. There are a range of options for a particular system data rate, with 40G and 100G being possible.
