I was trying to install Fiber LAN card(1000 based LX) of 3Com brand and vendor name "Cacheflow Inc" buto both those not supported by Mikrotik OS 3.23.

Which brand of fiber NIC is supported by Mikrotik3.23 ?

Only the connector is SFP not SC or ST, you can use patchcord from SC to SFP

Eko

Well not really a just a patchcord. You need an SFP/Mini-GBIC adapter. You can get those for copper and fiber.
