 Current is provided to the DBR chip through an SMA connector.  The central conductor of the SMA connects to the laser anode, and the shield connects to the laser cathode.  //This is a direct, unprotected connection to the DBR chip, so care must be taken to avoid ESD damage.// Current is provided to the DBR chip through an SMA connector.  The central conductor of the SMA connects to the laser anode, and the shield connects to the laser cathode.  //This is a direct, unprotected connection to the DBR chip, so care must be taken to avoid ESD damage.//
