1550nm高消光比强度调制器
The Photline MXER-LN series of intensity modulators is a family of high perfor-mance modulators exhibiting superior Extinction Ratio. Their specific design re-lies on iXblue “Magic Junction” (patent n° US2008193077).
MXER-LN series intensity modulators are key devices in all applications where a combination of high extinction and high bandwidth is required: laser pulse picking prior optical amplification, pulse generation or lidar based sensing systems are a few examples, as well as fiber optics sensors.
FEATURES
• Superior extinction ratio: 40 dB
• High bandwidth
• X-cut for high stability
• Low drive voltage
• Low insertion loss
APPLICATIONS
• Pulse generation / picking
• Carrier suppression
• Fiber optics sensors
• Pulse applications
OPTIONS
• 20 GHz version
• 1060 nm, 1300 nm band versions
RELATED EQUIPMENTS
• Pulsed driver DR-PL
• MBC Automatic Bias Controllers

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
