Appendix C 10G Sfp+ Modules - Ruijie Networks RG-S2910C-XS-P Series Hardware Installation And Reference Manual

Ruijie Networks provides appropriate 10G SFP+ modules according to the types of interfaces of the switch modules. You
can select the SFP+ module to suit your specific needs. The following models and technical specifications of some 10G
SFP+ modules are listed for your reference.
Table C-1 Models and Technical Specifications of the 10G SFP+ Optical Module
Model
XG-SFP-SR-MM850
XG-SFP-LR-SM1310
XG-SFP-ER-SM1550
For the XG-SFP-ER-SM1550, do not use short distance optical fiber for the avoidance of the overload of the
optical receiver. If the optical power of the module's receiving end is larger than or equal to -1dBm, an
appropriate attenuator should be added on the link to make sure the optical power is less than -1dBm.
