Module Technical Specifications
The ZR XENPAK supports SMF and has an SC connector.
WARNING!
To prevent permanent damage to the ZR XENPAK and other equipment: always check the optical input power of the
receiver before inserting the fiber. The maximum optical input power for the receiver is -7 dBm. If you use optical
loopback for diagnostics purposes, the loopback requires a minimum of 10 dB optical attenuation. The
recommended attenuation range is 10 dB to 15 dB.
LX4 XENPAK
Table 106 describes the specifications for the LX4 XENPAK module.
The LX4 XENPAK supports multimode fiber (MMF) in intra-building connections and single-mode fiber
(SMF) for interbuilding connections and has an SC connector.
