Review: It just works!!! - Finding cheap optics that actually work is not always an easy endeavor. I have purchased multiple brands of optics for multiple switches by different vendors, and even with the “secret” command to enable 3rd party transceivers, they still don’t work. Since I had a chance to test out this brand, I jumped at it and requested the 40G QSFP+ (Arista) and figured I’d give it a shot. The optic arrived very well packaged in a blister pack tucked away in a box, simple but effective. I popped it in my Arista, changed the speed to 40g on my port and boom! I was up and running. I’ve included snapshots of all the applicable “show” commands for the transceiver but as a note, the “show interfaces eeprom” command outputs a lot of lines so that is in 2 pics Pros: • Cost • Shipping time (arrived next day) • Usability/interoperability • Specs Cons: • None so far, will update once I use the full 40g lane *I received this free as part of the Vine Voices Review program. My reviews and opinions are unbiased, honest and are never coerced from the vendor*
Review: Great module for connecting to the now very economical 40gig cards - This was my 9th Opstran module. I have a 100gig switch that also supports lower speeds, and I put this in for connections to 40gig NICs in some of my hosts where a 3 foot DAC wouldn't work. Great choice, reasonable price, and consistent quality from Opstran.

This transceiver module worked on the first attempt in the Arista switch where installed. Testing resulted near 40Gbps without any errors or retransmits.
