Hardware Installation and Reference Guide Appendix

For the XG-SFP-ER-SM1550 and XG-SFP-ZR-SM1550 modules, please do not use short-distance fiber-optic cables for connection
to avoid overloading the optical receiver of the module. If the optical power at the receiving end of the module is greater than
or equal to -1 dBm, an appropriate attenuator should be added at the receiving end of the module to make the optical power
at the receiving end less than -1 dBm.
The module is a laser device. Please do not look into the laser beam directly.
To keep the module clean, please make sure that the dust cap is mounted when it is not connected to cables.
Table 7-8 10-Gigabit SFP+ Cable Modules and Specifications
You just need to plug both ends of the SFP+ cable module into the corresponding ports of the switches respectively. No extra
cable is required.
