Failure rates of optical transceivers

[mahiraman]

Hi,

We’ve been using for a long time transceivers (40G MPO) from an aftermarket vendor (fs.com) for our CISCO 3132Q-X usually they work well, but lately we have been seeing more failures than usual (suddenly a perfectly working transceiver starts having plenty of CRC errors that only go away once we replace the transceiver). Might be also related to the size of our deployment as, we have a several hundred optical transceivers (More units = more failures).

But lately we are wondering if it would make more sense to use original transceivers instead of aftermarket.

What’s your experience with aftermarket vs original optical transceivers? Reliability, MTBF, etc?

Thanks!

yes cisco always suggest to cisco one for better outcome also have life time warranty

Honest optic is same all models,. vendor to vendor flashing is different thats all.

Try fs.com (they better worth with cisco)

To be honest, we have stopped buying Cisco-branded optics for more than 5 years now.   

Aside from price, we use 3rd party optics for the following reasons: 

• 3rd party optics do not trigger bugs as often as Cisco-branded optics
• Compatibility-wise, we regularly encounter issues where we cannot use a specific CIsco-branded optics because of bugs, firmware needs to be upgrade.  If we use 3rd party optics we do not see such obstacles.
