光ファイバートランスポンダーのチュートリアル
光ファイバートランスポンダーとは何ですか?
光ファイバトランスポンダは、特定の用途に応じて波長変換トランスポンダ、WDMトランスポンダ、またはファイバ対ファイバメディアコンバータとしても知られ、WDM(波長分割多重)システム、特にDWDM(高密度波長分割多重)システムにおいて重要な役割を果たします。 「トランスポンダー」という名前は、送信機と応答機を組み合わせたもので、その目的がわかります。 これらは、最大 11.32 Gpbs のデータ レートの SFP、SFP+、XFP、および QSFP トランシーバーをサポートする、プロトコルおよびレート透過性のファイバー メディア コンバーターです。 光ファイバートランスポンダーは、波長 (1310 から 1550) を変換し、光パワーを増幅することでネットワーク距離を延長し、光信号のリタイム、再生、再形成という「3 つの R」をサポートできます。 一般に、このデバイスには O-E-O (光-電気-光) 機能があります。 光ファイバートランスポンダーと光マルチプレクサーは通常、端末マルチプレクサー内に存在します。

| 1R | 1R is shorthand for reamplification. It was used in the earliest fiber optic transponders. As the name implies, 1R does not employ any methods to "clean up" the signal. Rather, it simply takes the incoming external optical signal and converts it to analog. This process happened regardless of signal integrity. As a result, if the incoming optical signal was "junk", the analog version of it would be "junk" as well. Another consequence of 1R was that, because of the signal degradation inherent to long-range communications that would occur, the practical distance of DWDM systems was limited. |
| 2R | 2R is shorthand for reshaping and reamplification. Before the incoming external signal is reamplified, it first goes through a process to clean it up. The quality of the signals was monitored at this point. |
|
3R Reamplify, Retime, and Reshape |
3R is shorthand for reamplify, retime, and reshape. This system is more advanced than both 1R and 2R systems. Signal quality can be monitored more closely and accurately, thanks to the inclusion of quality bits embedded in the signal. The quality bits inform the system of the level of health and degradation of the signal. 3R systems are capable of the monitoring of bidirectional communication. |
| Muxponder or Multiplexed Transponder | Muxponder has different names depending on vendor. It essentially performs some relatively simple time division multiplexing of lower rate signals into a higher rate carrier within the system (a common example is the ability to accept 4 OC-48s and then output a single OC-192 in the 1550 nm band). More latest muxponder designs have absorbed more and more TDM functionality, in some cases obviating the need for traditional SONET/SDH transport equipment. |
