電光發射器與光電接收器

81490A 光電發射器專為 IEEE 802.3ae-LR、ER 相符性測試而最佳化。高達 35 GHz 的調變頻寬擴充了應用軟體功能，使其能夠產生任意調變光信號。

Keysight 81491A 參考發射器旨在為 NRZ 和 PAM4 信號提供出色的眼圖品質，速率高達 32Gbaud，可當作通用的 E/O 轉換器使用。

Keysight's 81491A Reference Transmitter is designed to offer excellent eye quality for NRZ and PAM4 signals at baud-rates up to 32Gbaud and can serve as universal E/O converter.

The 81495A reference receiver is ideally suited for IEEE 802.3ae-LR, -ER loop back compliance test. The linear transfer from optical to elctrical domain supports also O/E converter applications for oscilloscopes and spectrum analyzers.
