M4300-8X8F (XSM4316S) SFP+ compatibility

Hi danielator

Welcome to the Community!

Let me answer your questions, sequentially:

• Yes, M4300 series models, including our great half-width M4300-8X8F 16-port 10G switch with 8x10GBASE-T and 8xSFP+, can accept third-party SFP+ modules (SFP+ ports are not locked). Let me nuance that: we strive to offer maximum compatibility with standard based, high quality third-party modules, but we don't claim universal support. Our M4300 documentation specifies NETGEAR-only compatible modules. There are thousands of modules on the market, and NETGEAR designs and tests its switch products for use with genuine NETGEAR Modules only. The use of third-party modules may result in reduced network performance and reliability, such as packet loss and connectivity issues. While the use of third-party Modules does not affect the NETGEAR switch's warranty, NETGEAR may not provide technical support for networking problems it determines are caused by third-party Modules only.

• Yes, it is able to provide 1.5W power to the SFP/SFP+ modules.

• Only MSA standard SFP+ modules are meant to be allowed by our hardware and software.

Finally, I've looked at Gateway SDI-TO-IP SFP+ (emSFP) modules from Embrionix. We didn't test these modules. In reading the application note about MSA SFP & SFP+, I would strongly advise for SFP+ MSA Datacom SFF-8431 compliance. But still cannot attest we can successfully connect these modules. 

Feel free to explain more about your experience with these modules, such as: which switches did you test previously etc..
