Description:
  ● BIDI optical modules use different center wavelengths in the transmit and receive directions, thus enabling bi-directional transmission of optical signals within the same fiber.
        BIDI modules must be used in pairs, for example, if SFP- XG-LX-SM1330-BIDI is used at one end, must be used at the other end.
