Transceivers seem to work happily in a pair of SFP ports in some Unifi kit, including sending power and other sensor information to the devices.

Thank you for your prompt response Friday. I am trying to put a quick feasibility/confidence/proof of concept demonstration model together. (PS …I like and appreciate your online documentation, simple one-stop for everything.

The 10-12 working days to produce the cables were expected. Your website does a very good job explaining the timing of the order.

Yes, we strongly favor FS brand transceivers. They consistently work for us and are cost-effective.

Works perfect in our Fortinet switches

compatible with Ruijei network switch ?

I use them with Mikrotik routers & switches and ZyXEL GS range switches, as well as Siklu radios. Work fine and plan to keep using them (only have around 30 but so far so good).

Bought for my Cisco 3750 12s as well as some media converters MMC-GASFP and fiber cables to match and it was just plug and play. worked out of the box. i was worried about it being cheap rubbish but after testing, it has exceeded my expectations. delivery has been perfect getting overnight shipping and its overnight. no fuss, no issues and one very happy customer

What can I say? I plugged them into the switches and they worked and started passing data. Very pleased.
