2. Requires 5 dB 1550 nm fixed loss attenuator for < 20 km. Attenuator is available as a spare. The part number is 15216-ATT-LC-5=. You must
use a 5 to 10dB of attenuation when connecting a fiber loopback to the XFP optical port. Connection of a direct fiber loopback to the XFP can
permanently damage the port's optics.
