FAQ

Do modules from other manufacturers work with Cisco?

Cisco recommends using original modules for fullcompatibility and support. Third-party modules may not work oroperate with limitations.

Do I need a special license?

Some Cisco switch models require additional licenses tosupport high-speed modules (e.g., 100G/400G).

What is the difference between SR, LR and ER?

SR (Short Range) - up to 300m on MMF LR (Long Range) - up to 10km on SMF ER  (Extended Range) - up to 40km on SMF

What is a DOM?

Digital Optical Monitoring (DOM) allows monitoring of the module's operating parameters: temperature, voltage, optical power.

*Is the compatibility certified by Cisco or independently verified to meet industry standards?

Our products are designed to be compatible with devices from leading network equipment manufacturers, including Cisco. This compatibility is based on independent testing to meet industry standards and does not imply certification, partnership, or endorsement by Cisco or any other brand mentioned.
