POFLink's X2 is a standardized factor for *0 Gb/s fiber optic transponders that is used for data transfer rates *0.3 Gb/s to *0.5 Gb/s. It is protocol-specific: Either *0G Ethernet or *0G Fibre Channel versions are available. X2 transponders are used in datacom optical links only (not telecom), and they are smaller than old generation XENPAK transponders. Its electrical interface to the host board is also standardized and is called XAUI (4 x 3.**5 Gb/s).

POFLink manufactures X***0G-SR**0m, X***0G-LR*0km, X***0G-ER *0km, X***0G-ZR *0kmoptical modules. All modules support Digital Optical Monitoring (DOM) function .
