Ordered a ton of these, all arrived and are working in my Intel X710-B2 as well as my Dell S4128F-ON without issues.

Product is 100% compatible with the Cisco original for a fraction of the cost
Great fast free shipping
SUPER SUPPORT from the Sales including Rose Luo and Tyler..
Both amazingly competent, precise and very knowledgable folks.
Companies are not made Great but rather it is the employees that make it great !
Rose and Tyler are examples of that :)

Excellent SFP, compatible with everything I've tried so far.

Nice contact with representative, good service and quick delivery

Worked out of the box like a charm with my Mikrotik CRS510 switch and Intel XXV710 25G adapter card, even though this cable was pre-programmed to Cisco. I used FS 10ft multi-mode OM3 LC duplex cables, which it had no issues running 10G over. And I received the item in less than 3 days even though shipping was free.

Worked perfectly with my Cisco SG-300 switch. Thanks!
