Product description:
DF-318G-LRC transceivers are designed for using in Fiber Channel links up to 8.5Gb/s data rate over multimode fiber and compliant to SFI electrical specifications. The transmitter input and receiver output impedance is 100 Ohms differential.
Data lines are internally AC coupled.
The module provides differential termination and reduce differential to common mode conversion for quality signal termination and low EMI.
 

Pin definition: 
The SFP+ modules are hot-pluggable.  Hot pluggable refers to plugging in or unplugging a module while the host board is powered.  The SFP+ host connector is a 0.8 mm pitch 20 position right angle improved connector specified by SFF-8083, or stacked connector with equivalent with equivalent electrical performance.   Host PCB contact assignment is shown in Figure 2 and contact definitions are given in Table 2.   
 
SFP+ module contacts mates with the host in the order of ground, power, followed by signal as illustrated by Figure 3 and the contact sequence order listed in Table 2.
