There are only a hand full of actual MFG who make the optics, everything else is branding ..... :)
While there are many things that can go wrong with SFP's, but I can assure you "Packet Loss / CRC / FCS" are not due to SFP module compatibility with the Router/switch they are plugged into....(they will either work or not work) Connecting two SFP's of any brand, together (as long as the Light Freq.,light levels, Speed of SFP, matches correctly) is equivalent of using a Copper cable to connect two Ethernet ports together...... The Ethernet controller on the Router/Switch can have some issues due to negotiations, buffers etc, and the cable can be dirty or have a loose connection.... >>>>I really don't trust any MikroTik product to be very reliable, but they're >>>>cheap so we can have lots of spares. :) I have often heard this comment, but never quiet understood it.... are they not reliable because they are cheap to buy ? or are they not reliable because there is some technical short cuts taken in production ? or they are not reliable because we don't respect them (we pay a perceived 'little' for them) ? e.g. Do you think that a SFP Module with an IBM sticker that cost's $1000 is more reliable than a $30 SFP module with a Mikrotik Sticker on it ? I have news for you, there is a good chance that both units might have been mfg. in the same factory in China ! This perception of ...if it is not expensive then it is not reliable is the most serious kind of brain washing done in the world..
